Pornography, Individual Differences in Risk and Men’s Acceptance of Violence Against Women in a Representative Sample

Based on the Confluence Model of Sexual Aggression, we hypothesized that individual differences in risk for sexual aggression moderate the association between pornography use and attitudes supporting violence against women. This hypothesis was in keeping with the findings of a recent meta-analysis which indicated such a positive association between porn use and attitudes. However, in this meta-analysis there was also a high degree of heterogeneity among studies, suggesting the existence of crucial moderating variables. Unfortunately, the available literature included in this meta-analysis did not enable identifying the basis for such moderation. To fully test our hypothesis of individual differences moderation and related hypotheses requires a representative sample. Fortunately, a unique nationally representative sample of U.S. men in any form of post-high school education that we obtained in 1984–85 enabled testing our predictions. Participants had anonymously completed questionnaires that included items pertaining to pornography use, attitudes about violence against women, and other measures assessing risk factors highlighted by the Confluence Model. As predicted, while we found an overall positive association between pornography consumption and attitudes, further examination showed that it was moderated by individual differences. More specifically, as predicted this association was found to be largely due to men at relatively high risk for sexually aggression who were relatively frequent pornography consumers. The findings help resolve inconsistencies in the literature and are in line not only with experimental research on attitudes but also with both experimental and non-experimental studies assessing the relationship between pornography consumption and sexually aggressive behavior.     

The instantiation principle re-evaluated

Three experiments are presented in which different aspects concerning Heit and Barsalou's (1996) instantiation principle were investigated. Mean typicalities of subordinate categories within superordinates were predicted very accurately for all investigated concepts. Multiple instantiations were shown to yield somewhat better predictions than single instantiation. The instantiation principle also successfully predicted mean typicalities on a different level (i.e., in lower-level concepts). An alternative account of Heit and Barsalou's findings was also proven wrong. Finally, correspondence between empirically obtained and predicted standard deviations is argued to be dubious, because of several possible sources of bias in the observed and predicted values.     

Wittgenstein,Korsgaard and the Publicity of Reasons

In The Sources of Normativity (Korsgaard, Christine. The Sources of Normativity. Cambridge: Cambridge University Press, 1996), Christine Korsgaard tried to argue against what she called the ‘privacy’ of reasons, appealing to Wittgenstein's argument against the possibility of a private language. In recent work she continues to endorse Wittgenstein's perspective on the normativity of meaning, although she now emphasizes that her own argument was only meant to be analogous to the private language argument. The purpose of the present paper is to show that the Wittgensteinian perspective is not only not useful in support of Korsgaard's general project, but that it is positively inimical to it, in two ways. First, Wittgenstein opposes views on which principled or rule-following behavior requires that one be guided by anything like a mental representation of a rule or principle. But for Korsgaard, human action essentially requires this. Second, Wittgenstein systematically attempts to de-emphasize the importance of the first-personal perspective, and to emphasize the social functions even of concepts that might seem deployed primarily from that perspective: for example, concepts of sensations and intentions. This is the reverse of Korsgaard's emphasis. The paper also argues, however, that the private language argument does have some implications for a theory of rationality and reasons.     

Psychiatry in the labyrinth: Deconstructing deviancy

Abstract

Deviancy is a key concept in psychiatry and other therapeutic disciplines, because it dramatizes the way in which they depend on the establishment of norms, in order to justify their theory and practice. The writings of Derrida as well as Goethe provide a different view: that “deviation” from a “norm” can be fundamentally important to the well‐being of the norm. Thus deviancy can be viewed not as something to be “corrected” but rather as a creative possibility to be encouraged and shaped in productive ways. As a case of “deviancy” we have selected the writings of John Perceval, whose Narrative provides a critique of the mental‐health establishment of his day, particularly the asylum, and offers an alternative to 19th‐century views of “lunacy.” We see his “schizophrenic” commentary on his “psychosis” and its treatment as analogous to the deconstructive, “schizophrenic” discourse of postmodernity which is similarly critical of the reigning, modernist psychiatric order.     

Geometric and featural representations in semantic concepts

We explore the adequacy of two types of similarity representation in the context of semantic concepts. To this end, we evaluate different categorization models, assuming either a geometric or a featural representation, using categorization decisions involving familiar and unfamiliar foods and animals. The study aims to assess the optimal stimulus representation as a function of the familiarity of the stimuli. For the unfamiliar stimuli, the geometric categorization models provide the best account of the categorization data, whereas for the familiar stimuli, the featural categorization models provide the best account. This pattern of results suggests that people rely on perceptual information to assign an unfamiliar stimulus to a category but rely on more elaborate conceptual knowledge when assigning a familiar stimulus.     

The role of corpus size and syntax in deriving lexico-semantic representations for a wide range of concepts

One of the most significant recent advances in the study of semantic processing is the advent of models based on text and other corpora. In this study, we address what impact both the quantitative and qualitative properties of corpora have on mental representations derived from them. More precisely, we evaluate models with different linguistic and mental constraints on their ability to predict semantic relatedness between items from a vast range of domains and categories. We find that a model based on syntactic dependency relations captures significantly less of the variability for all kinds of words, regardless of the semantic relation between them or their abstractness. The largest difference was found for concrete nouns, which are commonly used to assess semantic processing. For both models we find that limited amounts of data suffice in order to obtain reliable predictions. Together, these findings suggest new constraints for the construction of mental models from corpora, both in terms of the corpus size and in terms of the linguistic properties that contribute to mental representations.     

Trajectories of Big Five Personality Traits: A Coordinated Analysis of 16 Longitudinal Samples

This study assessed change in self-reported Big Five personality traits. We conducted a coordinated integrative data analysis using data from 16 longitudinal samples, comprising a total sample of over 60 000 participants. We coordinated models across multiple datasets and fit identical multi-level growth models to assess and compare the extent of trait change over time. Quadratic change was assessed in a subset of samples with four or more measurement occasions. Across studies, the linear trajectory models revealed declines in conscientiousness, extraversion, and openness. Non-linear models suggested late-life increases in neuroticism. Meta-analytic summaries indicated that the fixed effects of personality change are somewhat heterogeneous and that the variability in trait change is partially explained by sample age, country of origin, and personality measurement method. We also found mixed evidence for predictors of change, specifically for sex and baseline age. This study demonstrates the importance of coordinated conceptual replications for accelerating the accumulation of robust and reliable findings in the lifespan developmental psychological sciences. © 2020 European Association of Personality Psychology
