Several studies have shown that our visual system may construct a “summary statistical representation” over groups of visual objects. Although there is a general understanding that human observers can accurately represent sets of a variety of features, many questions on how summary statistics, such as an average, are computed remain unanswered. This study investigated sampling properties of visual information used by human observers to extract two types of summary statistics of item sets, average and variance. (...) We presented three models of ideal observers to extract the summary statistics: a global sampling model without sampling noise, global sampling model with sampling noise, and limited sampling model. We compared the performance of an ideal observer of each model with that of human observers using statistical efficiency analysis. Results suggest that summary statistics of items in a set may be computed without representing individual items, which makes it possible to discard the limited sampling account. Moreover, the extraction of summary statistics may not necessarily require the representation of individual objects with focused attention when the sets of items are larger than 4. (shrink)

We contrast two theoretical positions on the relation between phenomenal and access consciousness. First, we discuss previous data supporting a mild Overflow position, according to which transient visual awareness can overflow report. These data are open to two interpretations: (i) observers transiently experience specific visual elements outside attentional focus without encoding them into working memory; (ii) no specific visual elements but only statistical summaries are experienced in such conditions. We present new data showing that under data-limited conditions observers cannot discriminate (...) a simple relation (same versus different) without discriminating the elements themselves and, based on additional computational considerations, we argue that this supports the first interpretation: summary statistics (same/different) are grounded on the transient experience of elements. Second, we examine recent data from a variant of ‘inattention blindness’ and argue that contrary to widespread assumptions, it provides further support for Overflow by highlighting another factor, ‘task relevance’, which affects the ability to conceptualize and report (but not experience) visual element.

Comparing datasets, that is, sets of numbers in context, is a critical skill in higher order cognition. Although much is known about how people compare single numbers, little is known about how number sets are represented and compared. We investigated how subjects compared datasets that varied in their statistical properties, including ratio of means, coefficient of variation, and number of observations, by measuring eye fixations, accuracy, and confidence when assessing differences between number sets. Results indicated that participants implicitly create and (...) compare approximate summary values that include information about mean and variance, with no evidence of explicit calculation. Accuracy and confidence increased, while the number of fixations decreased as sets became more distinct , demonstrating that the statistical properties of datasets were highly related to comparisons. The discussion includes a model proposing how reasoners summarize and compare datasets within the architecture for approximate number representation. (shrink)

This evenhanded treatment addresses the decades-old dispute among probability theorists, asserting that both statistical and inductive probabilities may be treated as sentence-theoretic measurements, and that the latter qualify as estimates of the former. Beginning with a survey of the essentials of sentence theory and of set theory, the author examines statistical probabilities, showing that statistical probabilities may be passed on to sentences, and thereby qualify as truth-values. An exploration of inductive probabilities follows, demonstrating their reinterpretation as estimates of truth-values. Each (...) chapter is preceded by a summary of its contents.

Background: Mental healthcare needs person-tailored interventions. Experience Sampling Method (ESM) can provide daily life monitoring of personal experiences. This study aims to operationalize and test a measure of momentary reward-related Quality of Life (rQoL). Intuitively, quality of life improves by spending more time on rewarding experiences. ESM clinical interventions can use this information to coach patients to find a realistic, optimal balance of positive experiences (maximize reward) in daily life. rQoL combines the frequency of engaging in a relevant context (a (...) ‘behavior setting’) with concurrent (positive) affect. High rQoL occurs when the most frequent behavior settings are combined with positive affect or infrequent behavior settings co-occur with low positive affect. Methods: Resampling procedures (Monte Carlo experiments) were applied to assess the reliability of rQoL using various behavior setting definitions under different sampling circumstances, for real or virtual subjects with low-, average- and high contextual variability. Furthermore, resampling was used to assess whether rQoL is a distinct concept from positive affect. Virtual ESM beep datasets were extracted from 1058 valid ESM observations for virtual and real subjects. Results: Behavior settings defined by Who-What contextual information were most informative. Simulations of at least 100 ESM observations are needed for reliable assessment. Virtual ESM beep datasets of a real subject can be defined by Who-What-Where behavior setting combinations. Large sample sizes are necessary for reliable rQoL assessments, except for subjects with low contextual variability. rQoL is distinct from positive affect. Conclusion: rQoL is a feasible concept. Monte Carlo experiments should be used to assess the reliable implementation of an ESM statistic. Future research in ESM should asses the behavior of summary statistics under different sampling situations. This exploration is especially relevant in clinical implementation, where often only small datasets are available. (shrink)

According to the Bayesian view, scientific hypotheses must be appraised in terms of their posterior probabilities relative to the available experimental data. Such posterior probabilities are derived from the prior probabilities of the hypotheses by applying Bayes'theorem. One of the most important problems arising within the Bayesian approach to scientific methodology is the choice of prior probabilities. Here this problem is considered in detail w.r.t. two applications of the Bayesian approach: (1) the theory of inductive probabilities (TIP) developed by Rudolf (...) Carnap and other epistomologists and (2) the analysis of the multinational inferences provided by Bayesian statstics (BS). ... Zie: Summary. (shrink)

In this paper, a criticism of the traditional theories of approximation and idealization is given as a summary of previous works. After identifying the real purpose and measure of idealization in the practice of science, it is argued that the best way to characterize idealization is not to formulate a logical model – something analogous to Hempel's D-N model for explanation – but to study its different guises in the praxis of science. A case study of it is then (...) made in thermostatistical physics. After a brief sketch of the theories for phase transitions and critical phenomena, I examine the various idealizations that go into the making of models at three difference levels. The intended result is to induce a deeper appreciation of the complexity and fruitfulness of idealization in the praxis of model-building, not to give an abstract theory of it. (shrink)

The distinction between access consciousness and phenomenal consciousness is a subject of intensive debate. According to one view, visual experience overflows the capacity of the attentional and working memory system: We see more than we can report. According to the opposed view, this perceived richness is an illusion—we are aware only of information that we can subsequently report. This debate remains unresolved because of the inevitable reliance on report, which is limited in capacity. To bypass this limitation, this study utilized (...) color diversity—a unique summary statistic—which is sensitive to detailed visual information. Participants were shown a Sperling-like array of colored letters, one row of which was precued. After reporting a letter from the cued row, participants estimated the color diversity of the noncued rows. Results showed that people could estimate the color diversity of the noncued array without a cost to letter report, which suggests that color diversity is registered automatically, outside focal attention, and without consuming additional working memory resources.

Three experiments examine the effect of base rate consistency under direct experience. Base rate consistency was manipulated by blocking trials and setting base rate choice reinforcement to be either consistent or inconsistent across trial blocks. Experiment 1 shows that, contrary to the usual finding, participants use base rate information more than individuating information when it is consistent, but less when it is inconsistent. In Experiment 2, this effect was replicated, and transferred in verbal questions posed subsequently. Despite experience with consistent (...) base rates increasing sensitivity to base rates in word problems, verbal responses were far from normative. In Experiment 3, participants’ use of base rates was once again moderated by its consistency, but this effect was itself moderated by the diagnosticity of base rate information. Participants were highly accurate in estimating experienced base rates. These studies demonstrate that base rate usage is complex and a function of how base rates are presented (experienced versus summary statistics) and response format (choice proportions versus probability estimates). Knowledge of base rates was insufficient for proper usage in verbal word problems. Although choice proportions showed a sophisticated sensitivity to experienced base rate information, participants seemed unable to demonstrate a similar sophistication when given typical word problems indicating that base rate neglect is a function of information representation and not an inherent processing bias.

Biological diversity would apparently seem the most intuitive and easily studied of all the ecological concepts. However, in practice biodiversity has suffered from great number of definitions that vary with the specific needs of the different researchers, thus making it extremely confusing as an ecological concept. In this paper, I shortly review the concept of biodiversity showing that there exists a substantial ambiguity among ecologists as far as biodiversity conceptualization and evaluation is concerned. I conclude that, due to this major (...) disagreement on its very nature, biodiversity may be defined simply as a set of multivariate summary statistics for quantifying different characteristics of community structure.

Ricotta argues against the existence of a unique measure of biodiversity by pointing out that no known measure of α-diversity satisfies all the adequacy conditions that have traditionally been set for it. While that technical claim is correct, it is not relevant in the context of defining biodiversity which is most usefully measured by β-diversity. The concept of complementarity provides a closely related family of measures of biodiversity which can be used for systematic conservation planning. Moreover, these measures cannot be (...) replaced by summary statistics but must rely on inventories of biodiversity surrogates at candidate sites for conservation. (shrink)

In the 24 years since the founding of BioEssays, the level of translational research, as well as the expectations for its success, have burgeoned.

Complex‐trait genetics has advanced dramatically through methods to estimate the heritability tagged by SNPs, both genome‐wide and in genomic regions of interest such as those defined by functional annotations. The models underlying many of these analyses are inadequate, and consequently many SNP‐heritability results published to date are inaccurate. Here, we review the modelling issues, both for analyses based on individual genotype data and association test statistics, highlighting the role of a low‐dimensional model for the heritability of each SNP. We (...) use state‐of‐art models to present updated results about how heritability is distributed with respect to functional annotations in the human genome, and how it varies with allele frequency, which can reflect purifying selection. Our results give finer detail to the picture that has emerged in recent years of complex trait heritability widely dispersed across the genome. Confounding due to population structure remains a problem that summary statistic analyses cannot reliably overcome. Also see the video abstract here: https://youtu.be/WC2u03V65MQ. (shrink)

Background Although, moral distress presents a serious problem among critical care nurses in many countries, limited research has been conducted on it. A validated scale has been developed to evaluate moral distress and has enabled cross-cultural comparison for seeking its root causes. Research aims This study aimed to (1) clarify the current status of moral distress among nurses who worked in critical care areas in Japan, (2) compare the moral distress levels among nurses in Japan with previously reported results from (...) the United States (US), and (3) explore the factors associated with moral distress. Research design A nationwide cross-sectional study was conducted. Participants and research context We conducted a self-administered questionnaire survey using the Measure of Moral Distress–Healthcare Professionals (MMD-HP) among critical care nurses who were randomly selected from hospitals across Japan. The mean differences between the two countries were compared using a Student's t-test with summary statistics. The factors associated with higher levels of moral distress were examined using a multiple regression analysis. Ethical considerations The study was approved by the Ethics Committee of the Tokyo Medical and Dental University (approval nos. M2018-214 and M2019-045). Results We obtained 955 valid responses from 94 facilities. In Japan, the items with the highest moral distress scores were those related to aggressive/inappropriate treatment. The total MMD-HP score was significantly higher in Japanese nurses compared to US nurses (122.8 ± 70.8 vs 112.3 ± 73.2). Some factors, such as leadership experience, were associated with higher moral distress. Discussion The top root causes of moral distress were similar to potentially inappropriate treatments in both countries. Conclusion This study revealed the factors associated with higher moral distress and its characteristics in each country. These results can be used for reducing moral distress in the future.

Summary Over the course of about two centuries, the population of Ancient Spartan full citizens – homoioi – declined precipitously. Historians typically ascribe structural, social and economic causes to this decline. In what follows, I use sample statistics to argue that despite scant evidence, the attrition rate suffered by Spartan armies on the battlefield was enough to intensify or cause the enormous population decline.

Transparency in data visualization is an essential ingredient for scientific communication. The traditional approach of visualizing continuous quantitative data solely in the form of summary statistics has repeatedly been criticized for not revealing the underlying raw data distribution. Remarkably, however, systematic and easy-to-use solutions for raw data visualization using the most commonly reported statistical software package for data analysis, IBM SPSS Statistics, are missing. Here, a comprehensive collection of more than 100 SPSS syntax files and an SPSS (...) dataset template is presented and made freely available that allow the creation of transparent graphs for one-sample designs, for one- and two-factorial between-subject designs, for selected one- and two-factorial within-subject designs as well as for selected two-factorial mixed designs and, with some creativity, even beyond. Depending on graph type, raw data can be displayed along with standard measures of central tendency and dispersion. The free-to-use syntax can also be modified to match with individual needs. A variety of example applications of syntax are illustrated in a tutorial-like fashion along with fictitious datasets accompanying this contribution. The syntax collection is hoped to provide researchers, students, teachers, and others working with SPSS a valuable tool to move towards more transparency in data visualization. (shrink)

This paper is based on the findings of research into the attitudes towards business ethics of a group of business students in Western Australia. The questionnaire upon which the research was based was originally used by Preble and Reichel (1988) in an investigation they undertook into the attitudes towards business ethics held by two similar groups of United States and Israeli business students. The specific purpose of the current investigation was to administer the same questionnaire with one minor modification to: (...) (1) two groups of Curtin University students; (2) a group of Asian students from the Australian Institute of Business and Technology (AIBT), a privately funded tertiary institution affiliated with Curtin University; and (3) a group of managers from the Australian Institute of Management (AIM), many of whom would not have been university graduates. The questionnaire was preceded by a profile inventory to establish the participant''s age, sex, occupation, course of study, whether or not they were born in Australia, their attitudes towards religion, and whether or not they saw themselves as ethically minded persons. In the original questionnaire, Preble and Reichel had asked the US and Israeli students to indicate on a five point scale, their attitudes towards a selection of business ethics situations by reflecting on thirty statements. In the replicate study, the means and standard deviations of each response of the four groups of Western Australian students were calculated and then compared with the means and standard deviations of the US and Israeli students. In summary, statistically significant differences in the scores of the original study were noted between nineteen out of thirty of the US and Israeli students in their attitudes towards business ethics. However, a closer examination and interpretation showed several of these differences to have little meaning. (p. 946) The purpose of this current study therefore, was to see if the Curtin, AIBT and AIM students'' results were statistically significant (different) to the US and Israeli student scores. The implications of understanding the way a selected group of business students in Western Australia react towards a range of ethical issues ought to have relevance for those involved in developing management education courses, particularly in view of the current economic and business climate. Studies into attitudes towards ethical issues in business have, as yet, received little attention in Australasia. This present study will hopefully lead to more thoughtful discussion of these issues.

Analysis of sites of newly integrated DNA in cellular genomes is important to several fields, but methods for analyzing and visualizing these datasets are still under development. Here, we describe tools for data analysis and visualization that take as input integration site data from our INSPIIRED pipeline. Paired-end sequencing allows inference of the numbers of transduced cells as well as the distributions of integration sites in target genomes. We present interactive heatmaps that allow comparison of distributions of integration sites to (...) genomic features and that support numerous user-defined statistical tests. To summarize integration site data from human gene therapy samples, we developed a reproducible report format that catalogs sample population structure, longitudinal dynamics, and integration frequency near cancer-associated genes. We also introduce a novel summary statistic, the UC50, which provides a single number summarizing possible clonal expansion. Using these tools, we characterize ongoing longitudinal characterization of a patient from the first trial to treat severe combined immunodeficiency-X1, showing successful reconstitution for 15 years accompanied by persistence of a cell clone with an integration site near the cancer-associated gene CCND2.

Summary Long-standing claims have been made for nearly the entire twentieth century that the biometrician, Karl Pearson, and his colleague, W. F. R. Weldon, rejected Mendelism as a theory of inheritance. It is shown that at the end of the nineteenth century Pearson considered various theories of inheritance (including Francis Galton's law of ancestral heredity for characters underpinned by continuous variation), and by 1904 he ?accepted the fundamental idea of Mendel? as a theory of inheritance for discontinuous variation. Moreover, (...) in 1909, he suggested a synthesis of biometry and Mendelism. Despite the many attempts made by a number of geneticists (including R. A. Fisher in 1936) to use Pearson's chi-square (X 2, P) goodness-of-fit test on Mendel's data, which produced results that were ?too good to be true?, Weldon reached the same conclusion in 1902, but his results were never acknowledged. The geneticist and arch-rival of the biometricians, Williams Bateson, was instead exceptionally critical of this work and interpreted this as Weldon's rejection of Mendelism. Whilst scholarship on Mendel, by historians of science in the last 18 years, has led to a balanced perspective of Mendel, it is suggested that a better balanced and more rounded view of the hereditarian-statistical work of Pearson, Weldon, and the biometricians is long overdue.

Summary Boltzmann's principle is part of classical physics, and one of the corner-stones of Planck's quantum theory. It is shown, why Planck's theory of radiation can be derived from this principle without abandoning classical physics, if due regard is taken of atomism. Finally, there is given an outline of a quantum theory completely based on statistical axioms without any appeal to nonclassical physical principles.

The usefulness of the statistic known as the p-value, as a means of quantify-ing the strength of evidence for the presence of an effect from empirical data has long been questioned in the statistical community. In recent years there has been a notable increase in the awareness of both fundamental and practical limitations of the statistic within the target research fields, and especially biomedicine. In this article I analyse the recently published article which, in summary, argues that with a (...) better understand-ing and thus more appropriate use of the statistic, many of the aforementioned limitations can be addressed. In particular, I demonstrate that the (often implicit) premises of this counterargument are questionable, in some cases arguably inconsistent, and that therefore the counterargument provides little if any justification for the continued use of the p-value. Additionally, my analysis should help researchers seeking to interpret their empirical data by illustrating the nuanced nature and the multiplicity of statistical, methodological, and epistemological issues which must be considered in this process.

Summary The journal Systematic Zoology is studied in order to see what effect factionalism in the taxonomic community had on the refereeing process. Publication patterns in the journal were largely independent of changes in editorship. Although the taxonomic community was subdivided into feuding factions during the period under study, little bias along these lines was discernible in the refereeing process when studied statistically. Several explanations are suggested for the wide-spread impression at the time that bias was pervasive.

The question of whether conscious experience is restricted by cognitive access and exhausted by report, or whether it overflows it—comprising more information than can be reported—is hotly debated. Recently, we provided evidence in favor of Overflow, showing that observers discriminated the color‐diversity (CD) of letters in an array, while their working‐memory and attention were dedicated to encoding and reporting a set of cued letters. An alternative interpretation is that CD‐discriminations do not entail conscious experience of the underlying colors. Here we (...) argue, based on conceptual considerations and consistency with neuroscience and phenomenology, in favor of the Overflow interpretation. (shrink)

Summary Between 1911 and 1914, Owen Richardson formulated a theory of photoelectricity based on thermodynamics and statistical reasoning. Although this theory succeeded in accounting for most of the relevant phenomena and despite the lack of competing causal or descriptive accounts of the phenomena, it failed to attract other physicists. This paper seeks the reasons for the neglect of this theory in contemporary cultures of photoelectric research. Four main causes of neglect are identified: the relatively high number and the nature (...) of the theory's assumptions, the contradiction of one of these assumptions with contemporary views, the failure to suggest new predictions or to account for hitherto unexplained regularities, and the view shared by many scientists that the problem of electromagnetic radiation required a radical solution that a descriptive theory could not provide. The expectation for a radical solution defines the revolutionary character of a research field. In the case of photoelectricity, it originated in a web of evidence to which other fields contributed. The very possibility of Richardson's theory shows that, taken separately, this phenomenon could receive an account which, unlike Einstein's light quantum, did not require deep changes in the conception of nature.

This book details how quantification can serve both as evidence and as an instrument of government, whether when dealing with statistics on employment, occupational health and economic governance, or when developing public management or target-driven policies. In the process, it presents a thought-provoking homage to Alain Desrosières, who pioneered ways to study large numbers and the politics underlying them. It opens with a summary of Desrosières's contributions to the field in which several generations of researchers detail how this (...) statistician and historian profoundly influenced them. This tribute, based on personal testimonies, bears witness to the vitality of the school of thought and analytical framework Desrosières initiated. Next, a collection of essays explores the statistical argument in the neoliberal era, examining issues such as counting the homeless in Europe, measuring the performance of public services, and quantifying the effects of public action on the unemployed in France. The third part details the uses of quantification. It reveals that although statistics are frequently used to the advantage of those in power, they can also play a vital role in challenging and resisting both the conventions underlying the measurements as well as the measurements themselves.Featuring the work of economists, historians, political scientists, sociologists, and statisticians, this title provides readers with a thoughtful look at an influential figure in the history of statistics. It also shows how statistics are used to direct public policy, the degree of conflict that is possible in their production, and the disputes that can develop around their uses. (shrink)

A number of recent discussions have argued that George Price's equationfor representing evolutionary change is a powerful and illuminatingtool, especially in the context of debates about multiple levels ofselection.

The relations between Price's equation and equationsfor evolutionary change using average fitness are closer than issometimes supposed. The two approaches achieve a similar kind ofstatistical summary of one generation of change, and (...) they achieve thisvia a similar loss of information about the underlying fitnessstructure.

Summary. — The following theorem is proved.: If the statistical predictions of quantum theory are true in general and. if the macroscopic world is not radically different from what is observed, then what happens macroscopically in one space-time region must in some cases depend on variables that are controlled by experimenters in far-away, space-like-separated. regions. By what happens macroscopically in one space-time region is meant specifically the occurrence or nonoccurrence of a macroscopic event, such as the d.etection and recording (...) of a particle by some macroscopic device. By a variable controlled. by an experimenter in a certain space-time region is meant specifically the experimental setting in that region of some macroscopic device, in which this setting is controlled. by an experimenter acting within that region. The theorem pertains speci6cally to experimental situations in which there .are two far-apart, spacelike-separated. regions in each of which there is a device that can be set at either of two alternative settings by an experimenter acting within ' that region. There. is also a long sequence of experimental results (4.e. events) in each of the two regions. The theorem asserts that, for some such cases, it is mathematically impossible, within the manifold.

Summary The study examined the relation between possible selves, academic performance, motivation, self?esteem and persistence on task. The assumption was that envisioning a desired end?state produces information processing favouring the desired state and, as a consequence, the action seems more likely and people are able to construct more efficient plans. We hypothesized that academic performance is best for subjects who are able to produce well?elaborated, vivid pictures of future selves. The sample consisted of 289 students, 14 and 15 years (...) old, of both sexes. The statistical analysis revealed that those who endorsed specific, elaborated positive selves outperformed the other groups in academic achievement. There was also indication that this group of students showed more persistence on task. The results are discussed in terms of their importance for the motivational role of possible selves in achievement situations. (shrink)

Summary Leading scholars offer perspectives from the philosophy of science on the crisis in psychiatric research that exploded after the publication of DSM-5. -/- Psychiatry and mental health research is in crisis, with tensions between psychiatry's clinical and research aims and controversies over diagnosis, treatment, and scientific constructs for studying mental disorders. At the center of these controversies is the Diagnostic and Statistical Manual of Mental Disorders (DSM), which—especially after the publication of DSM-5—many have found seriously flawed as a (...) guide for research. This book addresses the crisis and the associated “extraordinary science” (Thomas Kuhn's term for scientific research during a state of crisis) from the perspective of philosophy of science. The goal is to help reconcile the competing claims of science and phenomenology within psychiatry and to offer new insights for the philosophy of science. -/- The contributors discuss the epistemological origins of the current crisis, the nature of evidence in psychiatric research, and the National Institute for Mental Health's Research Domain Criteria project. They consider particular research practices in psychiatry—computational, personalized, mechanistic, and user-led—and the specific categories of schizophrenia, depressive disorder, and bipolar disorder. Finally, they examine the DSM's dubious practice of pathologizing normality. (shrink)

Summary The first systematic studies on the velocity of chemical reactions (now called reaction rates) were published in the 1850s and 1860s. Inquiring about the course of chemical change, their authors established empirical equations on the basis of their measurement results. But these laws, which represented reaction velocities as proportional to the actual concentration of the reagents, could not be given a physical foundation. The chemists themselves regarded their propositions as mere ad hoc hypotheses. In 1867 Leopold Pfaundler formulated (...) a qualitative theory of chemical processes based on Clausius's version of the kinetic gas theory (and more specifically on his theory of evaporation), and on Saint-Claire Deville's investigations of dissociation processes. Pfaundler's theory was based on farreaching analogies: between evaporation and dissociation; between the gaseous state and the activated state; and between evaporation- and chemical-equilibrium. Four points of Pfaundler's theory must be regarded as essential: (1) the reduction of chemical change to randomly occurring molecular collisions, only showing regularities in great numbers according to the laws of probability; (2) the idea that molecules are in different states of internal and external motion, which determines whether a collision results in a reaction; (3) the view of the reaction step as a transition from internal to external motion and vice versa; and (4) the introduction of a new molecular-kinetic definition of chemical affinity as the maximum of internal motion. With these assumptions, Pfaundler provided the empirical rate equations with a new statistical interpretation and a physical Justification. (shrink)

Verbal learning and memory summaries of older adults have usually been used to describe neuropsychiatric complaints. Bayesian hierarchical models are modern and appropriate approaches for predicting repeated measures data where information exchangeability is considered and a violation of the independence assumption in classical statistics. Such models are complex models for clustered data that account for distributions of hyper-parameters for fixed-term parameters in Bayesian computations. Repeated measures are inherently clustered and typically occur in clinical trials, education, cognitive psychology, and treatment (...) follow-up. The Hopkins Verbal Learning Test is a general verbal knowledge and memory assessment administered repeatedly as part of a neurophysiological experiment to examine an individual’s performance outcomes at different time points. Multiple trial-based scores of verbal learning and memory tests were considered as an outcome measurement. In this article, we attempted to evaluate the predicting effect of individual characteristics in considering within and between-group variations by fitting various Bayesian hierarchical models via the hybrid Hamiltonian Monte Carlo under the Bayesian Regression Models using ‘Stan’ package of R. Comparisons of the fitted models were done using leave-one-out information criteria, Widely applicable information criterion, and K-fold cross-validation methods. The full hierarchical model with varying intercepts and slopes had the best predictive performance for verbal learning tests [from the Advanced Cognitive Training for Independent and Vital Elderly study dataset] using the hybrid Hamiltonian-Markov Chain Monte Carlo approach.

_English summary_ This article investigates the impact of moral statistics on suicide in Denmark in the 19. century. Championed as a new European social science, moral statistics was able to reveal statistical regularity on social and moral issues – such as suicide. Statistics proved, firstly, that Denmark experienced one of the highest suicide rates in Europe. Secondly, as demonstrated in 1846 by the Danish physician C. J. Kayser, statistics uncovered that suicides over time occurred regularly in (...) the case of frequency, gender distribution, method of self-killing etc.. This new knowledge encouraged Danish statisticians and physicians to look for societal causes rather than the former theological focus on individual sin. The statistical representations of suicide paved the way for two different interpretations of suicide in the second half of the 19. century, one of which linked suicide rates to the evils of modernisation and secularisation of society, emphasizing drunkenness, alcoholism, and moral decline as causes of suicide. Another, less prevalent, explanation stressed the social and economic inequality of industrialisation as the cause of rising suicide rates. ‘The moral explanation’ prevailed and the official statistical reports as well as newspaper articles was clearly affected by the idea that the rising suicide rates of the 19. century reflected an attack on core values of bourgeois society; moral, sobriety and religion. This way suicide statistics was embedded in a broader social representation reflecting a fear of breakdown of traditional values in modern society. (shrink)

Summary Watters questions the universality of mental illness and warns of the harms that accompany the exportation of Western typologies to non-Western cultures. He is particularly concerned that these effects will be exacerbated by the upcoming revisions of the Diagnostic and Statistical Manual of Mental Disorders (DSM-V). Building on his examination of non-Western practices, Watters exposes the historical instability of mental health classifications in North America to question the validity of current DSM categories. Although Watters' warnings about the dangers (...) of the globalisation of the DSM are persuasive, they may be overreaching as our examination of the successful incorporation of Western created autism services, information, and interventions in the developing world suggests.

Many philosophers of science and methodologists have argued that the ability to repeat studies and obtain similar results is an essential component of science. A finding is elevated from single observation to scientific evidence when the procedures that were used to obtain it can be reproduced and the finding itself can be replicated. Recent replication attempts show that some high profile results – most notably in psychology, but in many other disciplines as well – cannot be replicated consistently. These replication (...) attempts have generated a considerable amount of controversy, and the issue of whether direct replications have value has, in particular, proven to be contentious. However, much of this discussion has occurred in published commentaries and social media outlets, resulting in a fragmented discourse. To address the need for an integrative summary, we review various types of replication studies and then discuss the most commonly voiced concerns about direct replication. We provide detailed responses to these concerns and consider different statistical ways to evaluate replications. We conclude there are no theoretical or statistical obstacles to making direct replication a routine aspect of psychological science. (shrink)

The received wisdom in statistical mechanics is that isolated systems, when left to themselves, approach equilibrium. But under what circumstances does an equilibrium state exist and an approach to equilibrium take place? In this paper we address these questions from the vantage point of the long-run fraction of time definition of Boltzmannian equilibrium that we developed in two recent papers. After a short summary of Boltzmannian statistical mechanics and our definition of equilibrium, we state an existence theorem which provides (...) general criteria for the existence of an equilibrium state. We first illustrate how the theorem works with a toy example, which allows us to illustrate the various elements of the theorem in a simple setting. After a look at the ergodic programme, we discuss equilibria in a number of different gas systems: the ideal gas, the dilute gas, the Kac gas, the stadium gas, the mushroom gas and the multi-mushroom gas. In the conclusion we briefly summarise the main points and highlight open questions. (shrink)

Cyber-bullying, and other issues related to violence being committed online in prosocial environments, are beginning to constitute an emergency worldwide. Institutions are particularly sensitive to the problem especially as far as teenagers are concerned inasmuch as, in cases of inter-teen episodes, the deterrent power of ordinary justice is not as effective as it is between adults. In order to develop the most suitable policies, institution should not be satisfied with statistics and sociological perspectives on the phenomenon, but rather seek (...) a deep ethical understanding—also referring to the biological and evolutionary past of human beings. The aim of this paper is to show a way to fill this theoretical gap, offering some answers that can illuminate future policy-oriented research and reflection. In order to do so, we will start by connecting our argument to evolutionary studies carried out in the past two decades, focusing on gossip as a tool for social assortment, thus endowed with a dual function: protect the group from free riders, intruders and bullies but also bully the deviant members. In the “Mediating gossip through social networks” section, we will see which aspects of gossip, vital for bullying, are co-opted by social network scenarios. A fundamental trait of human social life, that is the subdivision in smaller coalitions, or sub-groups, will be shown as missing in social networks dynamics—therefore constituting themselves as structurally violent. The “Why and how do social networks empower bullying?” section will deal with techno-ethical and epistemological concerns regarding how gossip, mediated by SN, manages to empower cyber-bullying. The “Self-gossip and self-mobbing in the light of the disruption of sub-moralities” section will characterize cyber-bullying as often sparked by self-gossip in a scenario where familiar sub-groups, which also mediate defense and mutual understanding, are disrupted. The “Discussion and conclusion” section will consist of a philosophical summary, divided in two parts: a pars destruens analyzing whether SN, in their actual configurations, are fit for being used by humans-like-us, and a pars construens examining the broad potential consequences of highly enforced regulation aimed at contrasting cyber-bullying.

Is truth in the law just plain truth - or something sui generis? Is a trial a search for truth? Do adversarial procedures and exclusionary rules of evidence enable, or impede, the accurate determination of factual issues? Can degrees of proof be identified with mathematical probabilities? What role can statistical evidence properly play? How can courts best handle the scientific testimony on which cases sometimes turn? How are they to distinguish reliable scientific testimony from unreliable hokum? These interdisciplinary essays explore (...) such questions about science, proof, and truth in the law. With her characteristic clarity and verve, Haack brings her original and distinctive work in theory of knowledge and philosophy of science to bear on real-life legal issues. She includes detailed analyses of a wide variety of cases and lucid summaries of relevant scientific work, of the many roles of the scientific peer-review system, and of relevant legal developments.

It is far from obvious that outside of highly specialized domains such as commercial agriculture, the methodology of biometrics—quantitative comparisons over groups of organisms—should be of any use in today’s bioinformatically informed biological sciences. The methods in our biometric textbooks, such as regressions and principal components analysis, make assumptions of homogeneity that are incompatible with current understandings of the origins of developmental or evolutionary data in historically contingent processes, processes that might have come out otherwise; the appropriate statistical methods are (...) those suited to random walks, not normal distributions. A valid methodology would further require that especially close attention be paid to the difference between aspects of processes that are plastic, those that encode their own histories or biographies, and the very small fraction of quantifications that can usefully and realistically be modeled as varying by colored noise around a central tendency that itself has some quantitative meaning. This point of view—that only a vanishingly small fraction of the quantitative information borne by any living organism is worth quantifying—is illustrated by some data on a human birth defect, namely, fetal alcohol syndrome. In a suggestive metaphor, the biometrician is like the pilgrim in Friedrich’s painting Der Wanderer über dem Nebelmeer, uncertain as to whether to measure the mountains or the clouds. The mountains stand for contingent history, the clouds for the subset of the data most closely matching controlled experiments suitable for quantitative biometric summary. Biometrics applies to the clouds, not the mountains. The success of statistical methods comes at the expense of all the theories that we simultaneously hold to be true about the biological materials to which they both pertain. Biometrics is thus complementary to all of the emerging reductionist sciences of biological structure. (shrink)

This article explains why Bohr does not need to discuss the projection postulate or the "problem of measurement". Beginning with a thumbnail sketch of Bohr 's general views, it is argued that Bohr interprets the state function as giving a statistical summary of experimental outcomes. Against the objection that Bohr was too much a microrealist to endorse such an instrumentalist statistical interpretation it is suggested that he rejected the issue of microrealism as not well formed. It is shown that (...) on his statistical interpretation Bohr does not need the projection postulate or face the usual problem of measurement. (shrink)

The aim of this study is to determine what kind of religious coping activities the refugee students forced to emigrate to Turkey due to the devastating reasons such as war and violation of rights apply in order to overcome their traumatic lives and the relationship between the use of these religious coping activities and their adaptation to the culture they live in. The fact that religion has important functions in dealing with all difficulties, especially forced migration, makes it a matter (...) of interest about what kind of religious coping process refugees have experienced for making their lives bearable. Therefore, this research is based on the assumption that the refugees mostly struggle with difficulties by using positive religious coping methods and try to achieve cultural adaptation through this struggle. The sample was selected from the refugee students from Syria, Iraq and Afghanistan continuing their education in different departments of Karabük University and in different high schools of Karabük National Education Directorate in 2017-2018 academic year. “Cultural Adaptation” and “Religious Coping Styles” scales were applied to the sample with an average age of 18. According to the research findings, cultural adaptation and positive religious coping levels of the sample group are above the average, and negative religious coping levels are below the average. There was found a positive meaningful correlation between cultural adaptation and positive religious coping of which relation was determined through some independent and demographic variables (r =.269). Therefore, it is thought that providing spiritual care for refugee students might increase the level of cultural adaptation.Summary: The aim of this study is to determine what kind of religious coping activities the refugee students forced to emigrate to Turkey due to the devastating reasons such as war and violation of rights apply in order to overcome their traumatic lives and the relationship between the use of these religious coping activities and their adaptation to the culture they live in. The fact that religion has important functions in dealing with all difficulties, especially forced migration, makes it a matter of interest about what kind of religious coping process refugees have experienced for making their lives bearable. Therefore, this research is based on the assumption that the refugees mostly struggle with difficulties by using positive religious coping methods and try to achieve cultural adaptation through this struggle. The study that was conducted according to correlational survey model, used the questionnaire technique by implementing the “Cultural Adaptation” and “Religious Coping Styles” scales together with a personal information form. The sample of the study was chosen by random sampling, and consisted of 112 volunteer refugee students from Syria, Iraq and Afghanistan, studying at different departments of Karabük University and different public high schools in Karabük. While analyzing the data, firstly, averages were calculated by obtaining total scores of the scales. In order to reveal whether students’ cultural adaptation levels differ by various variables or not, t-test (Independent Samples t-test), one-way analysis of variance (Oneway ANOVA) and Scheffe Test were applied. While analyzing relations related to religious coping, non-parametric ‘Man Whitney U’ and ‘Kruskall Wallis H’ tests were applied in accordance with the result of the normality test. In the study in which correlation test was applied to determine the relationship between cultural adaptation and religious coping, the lowest p-value was predicated as.05 to determine the level of statistical significance. According to the findings, sample group’s levels of cultural adaptation (=3,27) and positive religious coping (=3,42) were above the average, and the level of negative religious coping (=1,77) was below the average. Cultural adaptation levels of the sample group has shown significant statistical differences in terms of the nationality variable. Accordingly, Syrian students had higher cultural adaptation scores (=3,48) than Iraqi (=3,19) and Afghani students (=3,06), and the difference among them was statistically meaningful (p<.01). There wasn’t detected any significant relationship between ‘negative religious coping’ levels of the sample and demographic and other independent variables; however, there were seen statistically significant differences just in terms of nationality, gender and age range among other demographic variables. Accordingly, female students scored higher (= 64,46) in positive coping than male students (= 47,32). The difference between them is statistically meaningful (p<.01). Students at the ages of 21-24 scored higher in positive religious coping (= 70,54) and the difference between them and the students at the ages of 14-16 (= 47,47) reached meaningful level, next to this Syrian students had higher levels of positive religious coping (= 62,91) and this reached a meaningful difference (p<.01) when compared with the averages of Afghani students (= 42,63). Moreover, there was a positive significant relationship between cultural adaptation and positive religious coping (r=.269, n=112, p=.004).Forced migration caused by wars is a traumatic experience including material and moral loss. The greatest contribution of spirituality in this kind of negative experiences causing severe stress is through positive religious coping. Hence, religious and spiritual beliefs not only enable cognitive satisfaction by offering the most satisfying answers to traumatic victims’ search for meaning, yet also help them to accept the situation. This is caused due to a sense of devotion, and contribute to both their struggle with the trauma and their post-traumatic development. According to the research findings, there is a significant relationship between students’ cultural adaptation and ‘positive religious coping’ tendency. Therefore, providing these students with spiritual care and counseling might contribute to their integration process. Moreover, it has been seen that it is important to conduct value-centered projects and activities which would prevent both refugee students and locals to marginalize each other, and would improve the culture of living-together. It is also important to provide governmental and non-governmental support for these projects and activities. On the other hand, launching free language courses to resolve communication problems, which are obstacles for integration, and establishing socio-cultural networks in and around the campus for constituting more compatible relationships among the students would improve the students’ integration capability.

One of the important areas of study of religious psychology is to examine the reflection of worship in the spiritual life of individuals in the context of worship psychology. In this field survey, the relations between the level of meaning in life and hopelessness of individuals who performed the ʿUmra worship are examined. The study is conducted with 214 Turkish participants who performed ʿumra in Saudi Arabia. The collected data is analyzed by questionnaire technique. "Personal Information Form", " Meaning in (...) Life Questionnaire (MLQ)" and "Beck Hopelessness Scale" are used as data collection tools. The obtained data is analyzed in the SPSS 23.0 statistical program. One Sample t-Test, Pearson Moments Multiplication Correlation Analysis, Independent Sampling t-Test, One Way ANOVA and Tukey HSD tests are used to analyse the data. It is found that the research group's level of meaning in life above average; the level of hopelessness is below average significantly. There is a significant negative correlation between meaning in life and hopelessness, feelings about the future, loss of motivation, expectation about the future. There is a significant positive correlation between searched meaning and hopelessness and loss of motivation.Summary: Many religions have some types of worship involving visiting places considered as sacred and performing some rituals there. In Islam it is called ʿUmra, which is visiting the Kaʿba without being dependent on a certain time frame except for the pilgrimage month. There are certain rites to perform ʿumra, such as entering a state of iḥrām (ritual purity in which certain actions are not permissible), completing circumambulation, and saʿy (striving to do a certain act; walking) between the hills of al-Ṣafā and al-Marwa. ʿUmra worship is a comprehensive and versatile worship, which contains psychological, sociological, physical and financial characteristics.Studying the relationship between religious beliefs and practices, the religious rituals and their psychological effects and functions of ceremonies are the some essential research topics of Psychology of Religion. Existing research in this area usually reveals the existence of a positive relationship between the religious beliefs and practices and between meaning in life and hope. Individuals who believe in a religion can find a meaning and purpose in life through prayer and worship, and at the same time have more positive future expectation to endure the difficulties of life. Meaning and hope are intertwined, which complete each other. Hopelessness is closely related to depression and suicidal desire. There is a need to find meaning and purpose in life in order to hold on to life, and for looking to the future with confidence, and overcoming difficulties.It is known that people tend to be more religious and concentrating worship during periods of loss of meaning for various reasons. ʿUmra, which includes almost all type of worship, is a special worship, which has the potential to contribute to the individual's intense emotional life for gaining new awareness and developing different behaviours to cope with such difficulties. It is because the individual would have many experiences to see the cause of existence, the meaning of his/her life, and his/her future expectation during the ʿumra worship. Thus, he/she can overcome his/her hopelessness and loss of meaning and look to the situation from different perspectives. Therefore, in this study, the following questions are explored: Does ʿumra make a positive contribution to the psychological experience of the individuals, as expected? Does ʿumra has any effect on the level of loss of meaning and hopelessness that accompanies the psychological troubles? How does the demographic variables make difference in the level of meaning in life and hopelessness of individuals who perform ʿumra? In order to find answers to these questions, the relationship between the meaning of life - the hopelessness and the ʿumra was investigated. For this purpose, the meaning and hopelessness levels of the individuals who are performing ʿumra worship were measured by psychometric methods and the relations between them were analyzed. In addition, it has been tested whether there is a difference in the meaning in life and hopelessness according to demographic variables such as gender, marital status and educational status. 214 people aged between 18-82 years participated in the research. The survey data was collected from Turkish participants who perform ʿumra in the cities of Mecca and Medina in Saudi Arabia in May 2015. "Personal Information Form", " Meaning in Life Questionnaire (MLQ)" and "Beck Hopelessness Scale" were used as data collection tools. The obtained data were analyzed in the SPSS 23.0 statistical program. One Sample t-Test, Pearson Moments Multiplication Correlation Analysis, Independent Sampling t-Test, One Way ANOVA and Tukey HSD tests were used for the purpose of analysis of the data.The most important finding of the survey is meaning in life scores of individuals who are performing the ʿumra are above average (t = 20,50; p ˂ 0,01); and scores of hopelessness are below average significantly (t = -29,80; p ˂0,01). There is a significant negative correlation between presence of meaning subscale and hopelessness (r = -,288; p ˂ 0,01); and positive correlation between search for meaning subscale and hopelessness (r =,169; p ˂ 0,05) and loss of motivation (r =,285; p ˂ 0,01). The findings show that ʿumra can affect the meaning in life positively and the hopelessness negatively. There was no significant difference between the meaning in life scores and education level and gender variable (p ˃ 0,05). As the level of education increases, hopelessness scores decrease significantly (F = 2, 627; p ˂ 0,05). Hopelessness scores show a significant difference according to gender (t = -2,708; p ˂ 0,01). Men's hopelessness levels are significantly higher than women’s. Moreover, the meaning in life of married individuals is significantly higher than single individuals (F = 3,859; p ˂ 0,05). As the age and developmental stages progressed, meaning in life (F = 7,274; p ˂ 0,01) and hopelessness scores (F = 8,119; p ˂ 0,01) significantly increased.ʿUmra may have a rapid and intensive effect on the psychology of the individual and his/her sense of world. Relevant studies in the literature also imply such results. Since ʿumra is both a journey and a collective worship, it involves many types of worship, such as praying, reading scripture, repentance and so on. The findings of this study were discussed with reference to the findings about pilgrimage and the findings of study of meaning in life and hopelessness in different samples. On the other hand, the conditions in which the data collected, the study group chosen, the instruments and techniques used for this research constitute the limitations of the present study. However, the time period in which the worship was practiced and reaching the participants in these places of worship, and the measurement of the level meaning in life and hopelessness associated with their worship of ʿumra indicates the importance and originality of this research. The results can be used in other research projects. Studies on the different psychological effects of ʿumra worship can be enriched by longitudinal investigations. (shrink)

With the continual development of artificial intelligence and smart computing in recent years, quantitative approaches have become increasingly popular as an efficient modeling tool as they do not necessitate complicated mathematical models. Many nations have taken steps, such as transitioning to online schooling, to decrease the harm caused by coronaviruses. Inspired by the demand for technology in early education, the present research uses a radial basis function neural network modeling technique to predict preschool instructors’ technology usage in classes based on (...) recognized determinant characteristics of technology acceptance. In this regard, this study utilized the RBFNN approach to predict preschool teachers’ technology acceptance behavior, based on the theory of planned behavior, which states that behavioral achievement, in our case the actual technology use in class, depends on motivation, intention and ability, and behavioral control. Thus, this research design is based on an adapted version of the technology acceptance model with eight dimensions: D1. Perceived usefulness, D2. Perceived ease of use, D3. Perceived enjoyment, D4. Intention to use, D5. Actual use, D6. Compatibility, D7. Attitude, and D8. Self-efficacy. According to the TAM, actual usage is significantly predicted by the other seven dimensions used in this research. Instead of using the classical multiple linear regression statistical processing of data, we opted for a NN based on the RBF approach to predict the actual usage behavior. This study included 182 preschool teachers who were randomly chosen from a project-based national preschool teacher training program and who responded to our online questionnaire. After designing the RBF function with the actual usage as an output variable and the other seven dimensions as input variables, in the model summary, we obtained in the training sample a sum of squares error of 37.5 and a percent of incorrect predictions of 43.3%. In the testing sample, we obtained a sum of squares error of 14.88 and a percent of incorrect predictions of 37%. Thus, we can conclude that 63% of the classified data are correctly assigned to the models’ dependent variable, i.e., actual technology use, which is a significant rate of correct predictions in the testing sample. This high significant percentage of correct classification represents an important result, mainly because this is the first study to apply RBFNN’s prediction on psychological data, opening up a new interdisciplinary field of research.

A central goal of the scientific endeavor is to explain phenomena. Scientists often attempt to explain a phenomenon by way of representing it in some manner—such as with mathematical equations, models, or theory—which allows for an explanation of the phenomenon under investigation. However, in developing scientific representations, scientists typically deploy simplifications and idealizations. As a result, scientific representations provide only partial, and often distorted, accounts of the phenomenon in question. Philosophers of science have analyzed the nature and function of how (...) scientists construct representations, deploy idealizations, and provide explanations. As such, our aim in this special issue is to bring these three pillars of research into closer contact with the contributions to it focusing on three main themes. -/- The first set of papers, Alan Baker (2021) and Marc Lange (2021), address mathematical explanations in science. Baker (2021), a proponent of mathematical Platonism, examines its capacity to evade the critique that the so-called Enhanced Indispensability Argument is circular. Lange (2021) examines distinctively mathematical explanations, arguing that neither Platonism nor representationalism are successful paths, and instead argues in favor of Aristotelian realism. A second theme emerging from the papers in this special issue is the impact that various conceptualizations of idealization have on our abilities to offer scientific explanations, to pro- duce an analysis of what explanations are or should be, and to understand scientific representation. Peter Tan (2021) suggests amending inferentialist accounts of scientific representation to account for inconsistent idealizations. Michael Strevens (2021) advocates a view wherein the introduction of idealizations into a model is legitimate so long as it pertains to non-difference-making factors, arguing for a logical reading of the notion of difference-making. Natalia Carrillo and Tarja Knuuttila (2022) offer an alternative account to the idealization-as-distortion view, emphasizing instead the holistic nature of idealization. -/- Finally, contributions by Carrillo and Knuuttila (2022), Terzian (2021), Valente (2021), and Rodriguez (2021) illustrate how issues regarding idealization, representation, and explanation are applied to specific contexts and across various sciences. Carrillo and Knuuttila (2022) examine conceptions of idealization in the context of models of the nerve impulse. Giulia Terzian (2021) extends the discussion of idealizations to the context of generative linguistics. Giovanni Valente (2021) examines how idealizations and evaluations of accurate representation impact capacities to explain phenomena in the context of statistical thermodynamics. Quentin Rodriguez (2021) examines the role of idealizations and analogies in various strategies to explain critical phenomena. -/- In what follows, we offer a brief overview of important philosophical issues connected to representation, idealization, and explanation in science. We then provide short summaries of the eight papers in this special issue. (shrink)

Good scientific research depends on critical thinking at least as much as factual knowledge; psychology is no exception to this rule. And yet, despite the importance of critical thinking, psychology students are rarely taught how to think critically about the theories, methods, and concepts they must use. This book shows students and researchers how to think critically about key topics such as experimental research, statistical inference, case studies, logical fallacies, and ethical judgments. Using updated research findings and new insights, this (...) volume provides a comprehensive overview of what critical thinking is and how to teach it in psychology. Written by leading experts in critical thinking in psychology, each chapter contains useful pedagogical features, such as critical-thinking questions, brief summaries, and definitions of key terms. It also supplies descriptions of each chapter author's critical-thinking experience, which evidences how critical thinking has made a difference to facilitating career development. (shrink)

Issues concerning scientific explanation have been a focus of philosophical attention from Pre- Socratic times through the modern period. However, recent discussion really begins with the development of the Deductive-Nomological (DN) model. This model has had many advocates (including Popper 1935, 1959, Braithwaite 1953, Gardiner, 1959, Nagel 1961) but unquestionably the most detailed and influential statement is due to Carl Hempel (Hempel 1942, 1965, and Hempel & Oppenheim 1948). These papers and the reaction to them have structured subsequent discussion concerning (...) scientific explanation to an extraordinary degree. After some general remarks by way of background and orientation (Section 1), this entry describes the DN model and its extensions, and then turns to some well-known objections (Section 2). It next describes a variety of subsequent attempts to develop alternative models of explanation, including Wesley Salmon's Statistical Relevance (Section 3) and Causal Mechanical (Section 4) models and the Unificationist models due to Michael Friedman and Philip Kitcher (Section 5). Section 6 provides a summary and discusses directions for future work. (shrink)
