Children’s ability to pretend, and the apparent lack of pretence in children with autism, have become important issues in current research on ‘theory of mind’, on the assumption that pretend play may be an early indicator of metarepresentational abilities.

In this paper we call for attention to be paid to the link between logic and geometry. To apply this theme, we survey the connection between n-cubes, Lukasiewicz logics and Ulam games. We then extend what is known to the case where the number of permitted lies in a Ulam game exceeds 1. We conclude by identifying the precise sense in which these logics are paraconsistent.

Fundamental movement skill proficiency does not develop solely due to maturation, but also via diverse perceptual-motor experiences across childhood. Practicing gymnastics has been shown to improve postural control. The purpose of the present study was to examine potential changes to postural control of children following a course of educational gymnastics. Two groups of children both completed 20 × 45-min physical education lessons; one group completed educational gymnastics lessons in school delivered by a professional coach, the other group completed their typical (...) PE classes. Unipedal balancing performance was assessed by calculating the percentage of successful trials made. Postural sway dynamics were explored by calculating center-of-pressure sample entropy, 95% ellipse sway area and sway velocity. Measurements were taken before the lessons began and immediately after the lessons were completed. The gymnastics group performed better than the typical PE group at unipedal balancing. Females outperformed males in both groups. Males made different changes to postural control compared to females across 3 months. Educational gymnastics enabled children in a critical period of development to make more rapid improvements to postural performance and control. Novel movement experiences, like those offered by educational gymnastics, may have a positive influence on postural control and importantly, physical literacy. Future work should examine how sex effects the development of postural control strategies in young children. (shrink)

This book addresses the challenges of living together after empire in many post-colonial cities. It is organized in two sections. The first section focuses on efforts by people of multiple faiths to live together within their contexts, including such efforts within a neighborhood in urban Manchester; the array of attempts at creating multi-faith spaces for worship across the globe; and initiatives to commemorate divisive conflict together in Northern Ireland. The second section utilizes particular postcolonial methods to illuminate pressing issues within (...) specific contexts—including women’s leadership in an indigenous denomination in the variegated African landscape, and baptism and discipleship among Dalit communities in India. In the context of growing multiculturalism in the West, this volume offers a postcolonial theological resource, challenging the epistemologies in the Western academy. (shrink)

University students are at elevated risk for psychological distress, especially during the COVID-19 pandemic. The aim of this study was to warmly contact our students and investigate the psychological impact of the COVID-19 pandemic on the subjective wellbeing and levels of psychological symptoms of university students in Belgium. All bachelor and master students of the Vrije Universiteit Brussels were invited for a brief structured telephone interview in March, 2021. In total, 7,154 students were assessed by a structured interview, based on (...) the Kessler Psychological Distress Scale and the Anamnestic Comparative Self-Assessment. Compared to a representative sample, students considered their life during the pandemic as less satisfying compared to their life before the pandemic. Overall, all students have suffered from COVID-19 and the measures taken to contain the pandemic. Twenty percent of our sample of 7,154 VUB students scored above the K6 cutoff, indicating a heightened risk for having a diagnosable mental illness severe enough to cause functional limitations and to require treatment. This study highlights the need for psychological support for all students, during the COVID-19 pandemic. (shrink)

The past 50 years have seen an accumulation of evidence suggesting that associative learning depends on high-level cognitive processes that give rise to propositional knowledge. Yet, many learning theorists maintain a belief in a learning mechanism in which links between mental representations are formed automatically. We characterize and highlight the differences between the propositional and link approaches, and review the relevant empirical evidence. We conclude that learning is the consequence of propositional reasoning processes that cooperate with the unconscious processes involved (...) in memory retrieval and perception. We argue that this new conceptual framework allows many of the important recent advances in associative learning research to be retained, but recast in a model that provides a firmer foundation for both immediate application and future research.

The reconciliation of theories of concepts based on prototypes, exemplars, and theory-like structures is a longstanding problem in cognitive science. In response to this problem, researchers have recently tended to adopt either hybrid theories that combine various kinds of representational structure, or eliminative theories that replace concepts with a more finely grained taxonomy of mental representations. In this paper, we describe an alternative approach involving a single class of mental representations called “semantic pointers.” Semantic pointers are symbol-like representations that result (...) from the compression and recursive binding of perceptual, lexical, and motor representations, effectively integrating traditional connectionist and symbolic approaches. We present a computational model using semantic pointers that replicates experimental data from categorization studies involving each prior paradigm. We argue that a framework involving semantic pointers can provide a unified account of conceptual phenomena, and we compare our framework to existing alternatives in accounting for the scope, content, recursive combination, and neural implementation of concepts.

Throughout the biological and biomedical sciences there is a growing need for, prescriptive ‘minimum information’ (MI) checklists specifying the key information to include when reporting experimental results are beginning to find favor with experimentalists, analysts, publishers and funders alike. Such checklists aim to ensure that methods, data, analyses and results are described to a level sufficient to support the unambiguous interpretation, sophisticated search, reanalysis and experimental corroboration and reuse of data sets, facilitating the extraction of maximum value from data sets (...) them. However, such ‘minimum information’ MI checklists are usually developed independently by groups working within representatives of particular biologically- or technologically-delineated domains. Consequently, an overview of the full range of checklists can be difficult to establish without intensive searching, and even tracking thetheir individual evolution of single checklists may be a non-trivial exercise. Checklists are also inevitably partially redundant when measured one against another, and where they overlap is far from straightforward. Furthermore, conflicts in scope and arbitrary decisions on wording and sub-structuring make integration difficult. This presents inhibit their use in combination. Overall, these issues present significant difficulties for the users of checklists, especially those in areas such as systems biology, who routinely combine information from multiple biological domains and technology platforms. To address all of the above, we present MIBBI (Minimum Information for Biological and Biomedical Investigations); a web-based communal resource for such checklists, designed to act as a ‘one-stop shop’ for those exploring the range of extant checklist projects, and to foster collaborative, integrative development and ultimately promote gradual integration of checklists.

There is certainly a need for a framework to guide the study of the physiological mechanisms underlying the experience of music and the emotions that music evokes. However, this framework should be organised hierarchically, with musical anticipation as its fundamental mechanism.

The Trompenaars database (1993) updated with Hampden-Turner (1998) has been assembled to help managers structure their cross cultural experiences in order to develop their competence for doing business and managing across the world. The database comprises more than 50,000 cases from over 100 countries and is one of the world's richest sources of social constructs. Woolliams and Trompenaars (1998) review the analysis undertaken by the authors in the last five years to develop the methodological approach underpinning the work. Recently Trompenaars (...) with Hampden-Turner (Trompenaars and Woolliams, 1999) have extended the concepts into a new model on dilemma reconciliation of cultural differences. This paper reviews these latest updates in relation to dilemmas of cross-cultural business ethics. The paper asserts that knowledge in relation to business ethics is culturally specific; and that ethnocentrism is not easy to avoid. Too great an emphasis on rational-analytic conceptions of reality may mean that syntheses, emotion, and intuition, are not adequately developed. This presents implications for doing business and managing across cultures and for resolving ethical dilemmas. (shrink)

Neural networks have long been used to study linguistic phenomena spanning the domains of phonology, morphology, syntax, and semantics. Of these domains, semantics is somewhat unique in that there is little clarity concerning what a model needs to be able to do in order to provide an account of how the meanings of complex linguistic expressions, such as sentences, are understood. We argue that one thing such models need to be able to do is generate predictions about which further sentences (...) are likely to follow from a given sentence; these define the sentence's “inferential role.” We then show that it is possible to train a tree-structured neural network model to generate very simple examples of such inferential roles using the recently released Stanford Natural Language Inference (SNLI) dataset. On an empirical front, we evaluate the performance of this model by reporting entailment prediction accuracies on a set of test sentences not present in the training data. We also report the results of a simple study that compares human plausibility ratings for both human-generated and model-generated entailments for a random selection of sentences in this test set. On a more theoretical front, we argue in favor of a revision to some common assumptions about semantics: understanding a linguistic expression is not only a matter of mapping it onto a representation that somehow constitutes its meaning; rather, understanding a linguistic expression is mainly a matter of being able to draw certain inferences. Inference should accordingly be at the core of any model of semantic cognition. (shrink)

In this article we address the question of how many impossible images Escher produced. To answer requires us first to clarify a range of concepts, including content, ambiguity, illusion, and impossibility. We then consider, and reject, several candidates for impossibility before settling on an answer.

It may seem that there is no need to review such a well-known book. This is the second edition of Peter Singer's text, Practical Ethics. The first edition has been widely used and influential; indeed for many it defines the field of applied ethics. The field is lucky; rarely is such popular work so carefully argued, so factually well informed and so well written. In addition, it is unusual for the author of a basic text to be so daring. (...) Peter Singer deserves credit for placing the interests of animals and famine victims on the agenda of applied ethics, and for making that agenda so prominent in public fora. But it behooves us to scrutinize carefully the power of definitive works as well. What sets the agenda is, for that very reason, more difficult to assess critically. (shrink)

We use a spiking neural network model of working memory capable of performing the spatial delayed response task to investigate two drugs that affect WM: guanfacine and phenylephrine. In this model, the loss of information over time results from changes in the spiking neural activity through recurrent connections. We reproduce the standard forgetting curve and then show that this curve changes in the presence of GFC and PHE, whose application is simulated by manipulating functional, neural, and biophysical properties of the (...) model. In particular, applying GFC causes increased activity in neurons that are sensitive to the information currently being remembered, while applying PHE leads to decreased activity in these same neurons. Interestingly, these differential effects emerge from network-level interactions because GFC and PHE affect all neurons equally. We compare our model to both electrophysiological data from neurons in monkey dorsolateral prefrontal cortex and to behavioral evidence from monkeys performing the DRT. (shrink)

Linear structural equation models (SEMs) are widely used in sociology, econometrics, biology, and other sciences. A SEM (without free parameters) has two parts: a probability distribution (in the Normal case specified by a set of linear structural equations and a covariance matrix among the “error” or “disturbance” terms), and an associated path diagram corresponding to the functional composition of variables specified by the structural equations and the correlations among the error terms. It is often thought that the path diagram is (...) nothing more than a heuristic device for illustrating the assumptions of the model. However, in this paper, we will show how path diagrams can be used to solve a number of important problems in structural equation modelling. (shrink)

Brain imaging studies have consistently shown subgenual Anterior Cingulate Cortical (sgACC) involvement in emotion processing. COMT Val158 and Met158 polymorphisms may influence such emotional brain processes in specific ways. Given that resting-state fMRI (rsfMRI) may increase our understanding on brain functioning, we integrated genetic and rsfMRI data and focused on sgACC functional connections. No studies have yet investigated the influence of the COMT Val158Met polymorphism (rs4680) on sgACC resting-state functional connectivity (rsFC) in healthy individuals. A homogeneous group of sixty-one Caucasian (...) right-handed healthy female university students, all within the same age range, underwent rsfMRI. Compared to Met158 homozygotes, Val158 allele carriers displayed significantly stronger rsFC between the sgACC and the left parahippocampal gyrus, ventromedial parts of the inferior frontal gyrus, and the nucleus accumbens (NAc). On the other hand, compared to Val158 homozygotes, we found in Met158 allele carriers stronger sgACC rsFC with the medial frontal gyrus, more in particular the anterior parts of the medial orbitofrontal cortex. Although we did not use emotional or cognitive tasks, our sgACC rsFC results point to possible distinct differences in emotional and cognitive processes between Val158 and Met158 allele carriers. However, the exact nature of these directions remains to be determined. (shrink)

Creativity is an important quality that has been linked with problem solving, achievement, and scientific advancement. It has previously been proposed that creative individuals pay greater attention to and are able to utilize information that others may consider irrelevant, in order to generate creative ideas (e.g., Eysenck, 1995). In this study we investigated whether there was a relationship between creativity and greater learning about irrelevant information. To answer this question, we used a self-report measure of creative ideation and a blocking (...) task, which involved learning about irrelevant stimuli. We failed to find evidence for this association, with a Bayes Factor indicating support for no relationship between these measures. While it is possible that a different measure of creative ideation, for example one which does not rely on self-report, may produce different results, a more lucrative research direction may be focusing on the link between creativity and cognitive flexibility, in line with suggestions by Zabelina and Robinson (2010).

In this response, we provide further clarification of the propositional approach to human associative learning. We explain why the empirical evidence favors the propositional approach over a dual-system approach and how the propositional approach is compatible with evolution and neuroscience. Finally, we point out aspects of the propositional approach that need further development and challenge proponents of dual-system models to specify the systems more clearly so that these models can be tested.

The current practice for UK research ethics committees (RECs) is to invite researchers to attend meetings at which their applications are to be considered and for student-based research the National Research Ethics Service recommends supervisors to attend. This study aims to identify the extent to which students and their supervisors attend NHS REC meetings and whether attendance is associated with the initial outcomes of RECs.

The United Nations General Assembly adopted the Universal Declaration of Human Rights in 1948. A burgeoning human rights movement followed, yielding many treaties and new international institutions and shaping the constitutions and laws of many states. Yet human rights continue to be contested politically and legally and there is substantial philosophical and theoretical debate over their foundations and implications. In this volume distinguished philosophers, political scientists, international lawyers, environmentalists and anthropologists discuss some of the most difficult questions of human rights (...) theory and practice: What do human rights require of the global economy? Does it make sense to secure them by force? What do they require in jus post bello contexts of transitional justice? Is global climate change a human rights issue? Is there a human right to democracy? Does the human rights movement constitute moral progress? For students of political philosophy, human rights, peace studies, and international relations.

In replying to certain objections to the existence of God, Robert Adams, Bruce Langtry, and Peter van Inwagen assume that God can appropriately choose a suboptimal world, a world less good than some other world God could have chosen. A number of philosophers, such as Michael Slote and Klaas Kraay, claim that these theistic replies are therefore committed to the claim that satisficing can be appropriate. Kraay argues that this commitment is a significant liability. I argue, however, that the (...) relevant defenses of theism are committed to the appropriateness of, not satisficing, but motivated submaximization. When one submaximizes with motivation, one aims at the optimum but accepts the good enough because of a countervailing consideration. When one satisfices, one aims at the good enough and chooses the good enough because it realizes her aim at the good enough. While commitment to the appropriateness of satisficing may be a significant liability, commitment to the appropriateness of motivated submaximization is not. (shrink)

BackgroundThe Supreme Court of Canada removed the prohibition on physicians assisting in patients dying on 6 February 2015. Bill C-14, legalising medical assistance in dying (MAID) in Canada, was subsequently passed by the House of Commons and the Senate on 17 June 2016. As this remains a divisive issue for physicians, the Canadian Neurosurgical Society (CNSS) has recently published a position statement on MAID.MethodsWe conducted a cross-sectional survey to understand the views and perceptions among CNSS members regarding MAID to inform (...) its position statement on the issue. Data was collected from May to June 2016.ResultsOf the 300 active membes of the CNSS who recevied the survey, 89 respondents completed the survey, 71% of whom were attending neurosurgeons and 29% were neurosurgery residents. Most respondents,74.2%, supported the right of physicians to participate in MAID with 7.8% opposing. 37% had current patients in their practice fitting the criteria for MAID. 23.6% had been asked by patients to assist with MAID, but only 11% would consider personally providing it. 84% of neurosurgeons surveyed supported the physicians’ right to conscientious objection to MAID while 21% thought attending surgeons should be removed from the inquiry and decision-making process. 43.8% agreed that the requirment to refer a patient to a MAID service should be mandatory. Glioblastoma multiforme (65%), quadriplegia/quadriparesis secondary to spinal tumour/trauma (54%) and Parkinson’s disease (24%) were the most common suggested potential indications for MAID among the neurosurgical population.ConclusionsOur results demonstrate that most neurosurgeons in Canada are generally supportive of MAID in select patients. However, they also strongly support the physicians’ right to conscientious objection. (shrink)

Peter Achinstein (1990, 1991) analyses the scientific debate that took place in the eighteenth and nineteenth centuries concerning the nature of light. He offers a probabilistic account of the methods employed by both particle theorists and wave theorists, and rejects any analysis of this debate in terms of coherence. He characterizes coherence through reference to William Whewell's writings concerning how "consilience of inductions" establishes an acceptable theory (Whewell, 1847) . Achinstein rejects this analysis because of its vagueness and lack (...) of reference to empirical data, concluding that coherence is insufficient to account for the belief change that took place during the wave-particle debate.

Non-presentist A-theories of time (such as the growing block theory and the moving spotlight theory) seem unacceptable because they invite skepticism about whether one exists in the present. To avoid this absurd implication, Peter Forrest appeals to the "Past is Dead hypothesis," according to which only beings in the objective present are conscious. We know we're present because we know we're conscious, and only present beings can be conscious. I argue that the dead past hypothesis undercuts the main reason (...) for preferring non-presentist A-theories to their presentist rivals, rivals which straightforwardly avoid skepticism about the present.

Don’t Look Up is a 2021 Netflix original film about two astronomers who discover a 9-kilometer “planet killer” comet on a collision course with Earth. The way humanity responds to this threat – which is less than ideal, given that the movie ends with humanity’s destruction – is supposed to be an allegory for how humanity is dealing with the real-world threat of climate change. Consequently, we argue, the movie is an argument that presents the viewer with a moral imperative: (...) Do all that you can to prevent climate change. But does the argument work? To answer this question, we look at criticism of the movie, decipher its messages, examine the aptness of its analogy, and use the philosophy of Plato, Kant, and Peter Singer to explain exactly what kind of argument the film is. In the end, we conclude that, while most (although not all) criticisms of the film fall flat – it doesn’t really matter. Given that the moral imperative presented by the movie is undeniable, the only appropriate response to the film is an unrelenting effort to fulfill our duty to stop climate change. (shrink)
