This brilliant exposition of the critique of identity is a classic in contemporary philosophy and one of Deleuze's most important works. Of fundamental importance to literary critics and philosophers,Difference and Repetition develops two central concepts—pure difference and complex repetition&mdasha;and shows how the two concepts are related. While difference implies divergence and decentering, repetition is associated with displacement and disguising. Central in initiating the shift in French thought away from Hegel and Marx toward Nietzsche and Freud, _Difference and Repetition_ moves deftly (...) to establish a fundamental critique of Western metaphysics.

Individual differences in police dog handlers The Polish adaptation of the NEO-FFI inventory was used in the present study to assess the personality of dog handlers. For diagnosis of the emotional intelligence, the Polish scale Popular Questionnaire of Emotional Intelligence was used. There were 601 participants out of the total estimated number of 1408 police dog handlers in Poland. The results were compared with normalization tests for the measures used. The personality profile and emotional intelligence of dog handlers differ (...) significantly from general population. Described in the NEO-FFI terms, police dog handlers are characterized by very low neuroticism, slightly above average extraversion, slightly below average openness to experience, a little above average agreeableness, and very high conscientiousness. In terms of emotional intelligence, they demonstrate higher control and understanding of emotions. It seems that the results obtained in the study may become relevant for the recruitment and training of police officers. (shrink)

There are four ways in which one might approach the concept of difference in the work of Jacques Derrida: difference as a poststructuralist critique of the supposedly post‐metaphysical attention to meaning as generated through systems; difference as the post‐phenomenological problem of time; sexual difference; and the difference between humans and non‐humans. This chapter deals with each of these problems of difference and the concept; but it is also important to begin by saying that différance is not a concept. It argues (...) with John Searle, Derrida made a claim for the force of concepts: a concept cannot have “fuzzy” boundaries, for a concept may only operate as a concept if it indicates a sense that would remain the same regardless of who speaks or how the concept is articulated: “when a concept is to be treated as a concept believe that one has to accept the logic of all or nothing.

In recent years postmodernism has been increasingly emphasizing difference to the point of rejecting anything resembling nature and essence out of fear of oppression and exclusion and for the sake of justice and liberation. In this article I argue that precisely for the sake of justice and liberation difference must be ‘sublated’ – in the Hegelian sense – into the solidarity of the different or others and that such solidarity requires a basis more enduring and more universal than the contingent (...) coincidence of interests shared by members of temporary coalitions. I make this argument by criticizing Derrida and such feminists as Iris Marion Young and Linda Nicholson on philosophical, historical, and strategic grounds. Philosophically, we need solidarity as much as we need difference. Historically, our contemporary challenge is not so much how to appreciate difference as how to find ways of living together for all our differences. Strategically, no group can effect its own liberation without solidarity with other groups. I also reconstitute a concept of human nature on the basis of a synthesis of classical objectivity and modern historicity and disclose solidarity as an essential characteristic of human nature itself that only needs activation, not invention, in the united struggle for justice and liberation.1.

Critics of a politics of difference have misidentified these social movements as asserting an identity politics of recognition. Most of these movements are better understood as resisting unjust structural inequalities.

« La différence anthropologique n’est pas l’exclusivité d’une philosophie toujours attachée à l’exception humaine, dont la biologie de l’évolution se serait affranchie en faisant de l’humain un animal comme les autres. La paléoanthropologie, qui étudie l’évolution humaine à partir de ses traces fossiles, reste partagée entre l’anti-anthropocentrisme impliqué par son ancrage dans l’évolutionnisme, et l’anthropocentrisme inhérent à son objet d’étude : confrontée à la question de ce qui fait l’unicité de « l’humain », aux différents niveaux taxinomiques de l’espèce Homo (...) sapiens, du genre Homo et de la tribu des Hominini, cette discipline mobilise des critères de définition de l’humain, nécessaires à l’interprétation des fossiles. Or la paléoanthropologie, précisément parce qu’elle est travaillée par cette injonction contradictoire, fournit à la philosophie des ressources pour penser l’humain en dehors des dualismes opposant la nature et la culture ou l’humain et l’animal. Nous nous intéresserons en particulier à la manière dont la diversité humaine du passé invite à renouveler des conceptions de l’humain qui ne reposent plus seulement sur l’identification de « propres de l’homme », mais aussi sur la confrontation à l’altérité d’autres humanités. ».

There is no difference between autonomy and non-psychopathy or, equivalently, between psychopathy and non-autonomy. Or rather, there is a difference, but it is tenuous, in that someone who is non-autonomous is non-psychopathic only as long the institution that hosts him is non-psychopathic. So his non-psychopathy, being borrowed, is both weak and ultimately devoid of reality.

Sex differences in aggressive and risk-taking behaviors have practical implications for sexual integration of military combat units. The social-role theory implies that female soldiers will adapt to their role and display the same aggressive and risk-taking propensities as their male comrades. If sex differences reflect evolved propensities, however, adoption of the soldier's role is unlikely to eliminate those differences.

Is there a moral obligation to reduce differences in income and wealth? There is an egalitarian tradition that condemns these differences, particularly as they arise in free-market capitalist society, as unfair or unjust. The opponents of this view argue that the material disparities of capitalist society have been brought about by voluntary mechanisms and thus accord with the freely exercised liberties of its citizens. They conclude that capitalist inequality is not vulnerable to the ethical complaints of its critics. (...) They maintain that the standard of living achieved as a by-product of the marketplace and its inequalities could not be adequately reproduced under egalitarian institutions. The essays in this volume, written by prominent economists, philosophers, and academic lawyers, assess the empirical and theoretical questions raised by inequalities of income and wealth. (shrink)

Computational science is intrinsically interdisciplinary; the methods of one scientist may be the objects of study for another. This essay is an attempt to develop an interdisciplinary framework that can analyse research into methods as a distinctive kind of epistemic orientation in science, drawing on two examples from fieldwork with a group of specialists in computer modelling. Where methods for simulation are objects of research in their own right, they are distinct in kind to the objects of simulation, and raise (...) a different set of sociological and philosophical questions. Drawing on the historian Hans-Jorg Rheinberger’s theory of epistemic objects, I ask: what kind of epistemic object does a method make, and how is research organized around it? I argue that methods become objects of research as purposeful things, in terms of their enrolment in the intentional structure of the experimental system. And, as methods research tends to be interventionary, in the sense that its mode of study creates and modifies its objects, we therefore observe a practical recursion, a dynamic of scientific reinvention, a ‘tuning’ of experimental systems that sheds light on the form of these systems’ historicity, their differential self-reproduction.

This essay argues that despite of the feminist critique of Merleau-Ponty his phenomenology can be positively appropriated to the theory of sexual difference. It focuses on three issues: the first one is closely linked to the Phenomenology of Perception and introduces a concept of "difference as differentiation". The second one is concerned with the intersubjective dimension of sexuality and will be called a "sexual syncretism". Finally, I’m referring to Merleau-Ponty's notion of "chiasm" in his late work The Visible and the (...) Invisible in order to apply it to the theory of sexual difference. At this point, the difference between sexual beings will be conceptualized as "chiasmatic intertwining". In doing so, I hope to show that Merleau-Ponty's phenomenology is a helpful resource for philosophical research that is mainly concerned with the questions of sexuality and sexual difference.

The relation between testosterone levels and aggressive behavior is well established. From an evolutionary viewpoint, testosterone can explain at least part of the sex differences found in aggressive behavior. This explanation, however, is mediated by factors such as prenatal testosterone levels and basal levels of cortisol. Especially regarding sex differences in aggression during adolescence, these mediators have great influence. Based on developmental brain structure research we argue that sex differences in aggression have a pre-pubertal origin and are (...) maintained during adolescence. Evidence of prenatal, adolescent, and adult levels of testosterone in relation to aggression taken together, support Archer's argument for sexual selection as the driver of sex differences in aggression.

A charitable sale housed in the Paris showrooms of Christie’s displayed works created by European artists. These were painted over or on the backs of specially commissioned carved house shutters typical of the Zafimaniry region of Madagascar. The present article considers and contrasts the two types of creativity juxtaposed at the Christie’s sale. The European work stresses the artist’s individual originality and social isolation from the everyday lives of those who come to admire or buy the works. The process of (...) the art’s production ends abruptly at the moment of exhibition and sale. In contrast, the work of the Malagasy carvers is contained within a general concern of continuing the life and growth of their families. Their art intends to harden and beautify the houses that represent the continuation of the families’ life. There is no disconnection between the carver and those who will see and use the shutters similar to that of the European artists, and there is no clear beginning or end to the process of creation similar to the point of exhibition and sale. The Malagasy carvers do not want to be different from their predecessors; they want to continue the work and lives of those they are in contact with. (shrink)

ABSTRACTOlder adults have greater difficulty than younger adults perceiving vocal emotions. To better characterise this effect, we explored its relation to age differences in sensory, cognitive and emotional functioning. Additionally, we examined the role of speaker age and listener sex. Participants aged 19–34 years and 60–85 years categorised neutral sentences spoken by ten younger and ten older speakers with a happy, neutral, sad, or angry voice. Acoustic analyses indicated that expressions from younger and older speakers denoted the intended emotion (...) with similar accuracy. As expected, younger participants outperformed older participants and this effect was statistically mediated by an age-related decline in both optimism and working-memory. Additionally, age differences in emotion perception were larger for younger as compared to older speakers and a better perception of younger as compared to older speakers was greater in younger as compared to older participants. Last, a female perception... (shrink)

This study sought to understand the effects of tone language repertoire and musical experience on nonnative lexical tone perception and production. Thirty-one participants completed a tone discrimination task, an imitation task, and a musical abilities task. Results showed that a larger tone language repertoire and musical experience both enhanced tone discrimination performance. However, the effects were not additive, as musical experience was associated with tone discrimination performance for single-tone language speakers, but such association was not seen for dual-tone language speakers. (...) Furthermore, among single-tone language speakers, but not among dual-tone language speakers, musical experience and musical aptitude positively correlated with tone discrimination accuracy. It is thus concluded that individuals with varying extents of tone language experience may adopt different strategies when performing tone discrimination tasks; single-tone language speakers may draw on their musical expertise while dual-tone language speakers may rely on their extensive tone language experience instead.

Much research in the last two decades has demonstrated that human responses deviate from the performance deemed normative according to various models of decision making and rational judgment (e.g., the basic axioms of utility theory). This gap between the normative and the descriptive can be interpreted as indicating systematic irrationalities in human cognition. However, four alternative interpretations preserve the assumption that human behavior and cognition is largely rational. These posit that the gap is due to (1) performance errors, (2) computational (...) limitations, (3) the wrong norm being applied by the experimenter, and (4) a different construal of the task by the subject. In the debates about the viability of these alternative explanations, attention has been focused too narrowly on the modal response. In a series of experiments involving most of the classic tasks in the heuristics and biases literature, we have examined the implications of individual differences in performance for each of the four explanations of the normative/descriptive gap. Performance errors are a minor factor in the gap; computational limitations underlie non-normative responding on several tasks, particularly those that involve some type of cognitive decontextualization. Unexpected patterns of covariance can suggest when the wrong norm is being applied to a task or when an alternative construal of the task should be considered appropriate. Key Words: biases; descriptive models; heuristics; individual differences; normative models; rationality; reasoning. (shrink)

Contemporary moral psychology has focused on the notion of a universal moral sense, robust to individual and cultural differences. Yet recent evidence has revealed individual differences in the psychological processes for moral judgment: controlled cognition, mental-state reasoning, and emotional responding. We discuss this evidence and its relation to cross-cultural diversity in morality.

The aims of this study were to analyze the peak physical demands in elite futsal by quantifying the most demanding scenarios of match play and to identify the differences between playing positions and the seasonal trend for five different rolling average time windows. The most demanding scenarios of external load from distance, speed, acceleration, and deceleration variables were obtained from 14 elite futsal players using a local positioning system during 15 official matches in the premier Spanish Futsal League. The (...) results showed an extremely large effect of the time window for all dependent variables in all positional groups. Another important finding of this study was that, in regard to the seasonal trend, only defenders reported clear moderate-large positive trends for high-speed running efforts, high-acceleration efforts, and high-deceleration efforts. Finally, moderate-large individual differences in player means for all dependent variables and clear differences between games for most dependent variables were found, suggesting how likely contextual factors may exert an influence on how “demanding” the most demanding scenarios are. The findings of this study provide coaches and strength and conditioning coaches further knowledge of the peak physical demands in elite futsal competition. This valuable information may lead to a more precise position-specific training prescription. (shrink)

Utilitarianism would allow any degree of inequality whatsoever productive of the greatest happiness of the greatest number. But it does not guide political action, because determining what level of inequality would produce the greatest happiness of the greatest number is opaque due to well-known psychological coordination problems. Does Rawlsian liberalism, as is generally assumed, have some superiority to Utilitarianism in this regard? This paper argues not; for Rawls’s ‘difference principle’ would allow any degree of inequality whatsoever that best raises up (...) the worst off, and similar psychological coordination problems apply. It concludes that Rawlsian liberalism, designed to solve the problem that Utilitarianism will not give us stable rules and will counsel their violation, and giving us in the process a contract and rights within a semi-consequentialist framework, repeats (in the difference principle) that very problem of Utilitarianism. It fails substantively to guide the level of inequalities permitted in such a framework. (shrink)

Social norm transgressions are assumed to be at the root of numerous substantial negative outcomes for transgressors. There is a prevailing notion among lay people and scholars that transgressing social norms can negatively impact one’s mental health. The present research aimed to examine this assumption, focusing on clinically relevant outcomes such as anxiety and depression. The present research further aimed to examine a social cognitive process for these outcomes in the form of fear of negative evaluations as a result of (...) one’s norm transgressing behavior. Specifically, it examined whether it is negative evaluations about ourselves or about those close to us that mediates the effect of social norm transgressions, and whether those may vary as a function of culture. Results of the present research, including a study with a community sample, suggest a positive association between social norm transgressions and psychological distress. Results also suggest that increased fear of negative evaluation mediates that association but does so differently for people from more collectivistic cultures and people from less collectivistic cultures. For people from more collectivistic cultures increased fear of negative evaluation of close others may mediate the association between social norm transgressions and psychological distress. However, for people from less collectivistic cultures that association may be mediated by increased fear of negative evaluation of oneself. Implications for research on consequences of social norm transgressions and cross-cultural differences in perceptions of such consequences are discussed as are practical implications for motivating social norm adherence and the maintenance of constructive social norms.

Traditional approaches to the fact that there are different religions with different characterizations of what is divine---exclusivism, inclusivism, and pluralism---live in fear of religious diversity and the possibility that what is divine is not one, not many, but diverse, i.e., that there are different gods that are potentially incompatible and conflicting. In this paper, I argue that this alternative--–religious diversity and an acknowledgment of the diversity of the divine--–is a more “realistic” approach to our understanding of religion and our experience (...) of what is divine.

Contemporary mate preferences can provide important clues to human reproductive history. Little is known about which characteristics people value in potential mates. Five predictions were made about sex differences in human mate preferences based on evolutionary conceptions of parental investment, sexual selection, human reproductive capacity, and sexual asymmetries regarding certainty of paternity versus maternity. The predictions centered on how each sex valued earning capacity, ambition— industriousness, youth, physical attractiveness, and chastity. Predictions were tested in data from 37 samples drawn (...) from 33 countries located on six continents and five islands. For 27 countries, demographic data on actual age at marriage provided a validity check on questionnaire data. Females were found to value cues toresource acquisitionin potential mates more highly than males. Characteristics signalingreproductive capacitywere valued more by males than by females. These sex differences may reflect different evolutionary selection pressures on human males and females; they provide powerful cross-cultural evidence of current sex differences in reproductive strategies. Discussion focuses on proximate mechanisms underlying mate preferences, consequences for human intrasexual competition, and the limitations of this study. (shrink)

Xenologica, for illustrative purposes, is applied to one of the most contentious domains of difference, race, with the aim of overcoming (...) some of the theoretical and practical limitations of classic antiracism.

The increasing digitalization in the field of psychological and educational testing opens up new opportunities to innovate assessments in many respects (e.g., new item formats, flexible test assembly, efficient data handling). In particular, computerized adaptive testing provides the opportunity to make tests more individualized and more efficient. The newly developed continuous calibration strategy (CCS) from Fink, Born, Spoden, and Frey (2018) makes it possible to construct computerized adaptive tests in application areas where separate calibration studies are not feasible. Due to (...) the goal of reporting on a common metric across test cycles, the equating is crucial for the CCS. The quality of the equating depends on the common items selected and the scale transformation method applied. Given the novelty of the CCS, the aim of the study was to evaluate different equating setups in the CCS and to derive practical recommendations. The impact of different equating setups on the precision of item parameter estimates and on the quality of the equating was examined in a Monte Carlo simulation, based on a fully crossed design with the factors common item difficulty distribution (bimodal, normal, uniform), scale transformation method (mean/mean, mean/sigma, Haebara, Stocking-Lord), and sample size per test cycle (50, 100, 300). The quality of the equating was operationalized by three criteria (proportion of feasible equatings, proportion of drifted items, and error of transformation constants). The precision of the item parameter estimates increased with increasing sample size per test cycle, but no substantial difference was found with respect to the common item difficulty distribution and the scale transformation method. With regard to the feasibility of the equatings, no differences were found for the different scale transformation methods. However, when using the moment methods (mean/mean, mean/sigma), quite extrem levels of error for the transformation constants A and B occurred. Among the characteristic curve method the performance of the Stocking-Lord method was slightly better than for the Haebara method. Thus, while no clear recommendation can be made with regard to the common item difficulty distribution, the characteristic curve methods turned out to be the most favorable scale transformation methods within the CCS.
