Self-dehumanisation in severe alcohol use disorder: Links with self-stigma and environmental satisfaction

Metadehumanisation (i.e., the perception of being considered as less than human by others) is proposed to be widespread in stigmatised populations, such as people with severe alcohol use disorder (SAUD). However, the relations between metadehumanisation, self-dehumanisation (i.e., the self-perception of being less than human), and stigmatisation (i.e., the negative taint applied to some groups) remain unexplored. The aim of this research is thus to investigate the relations between these processes. Metadehumanisation, self-dehumanisation, self-stigma (and its subdimensions) and environmental satisfaction were assessed in 120 inpatients with SAUD and analysed in a mediational model. Stigma awareness was positively associated with metadehumanisation, whereas environmental satisfaction was negatively associated with metadehumanisation. Stigma's application to the self was associated with increased self-dehumanisation. Self-stigma and self-dehumanisation are closely intertwined phenomena. Self-dehumanisation seems to follow a multi-step process suggesting that some steps, such as dehumanisation awareness, are missing from current models of dehumanisation.     

Prevalence of Nonsuicidal Self‐Injury in Nonclinical Samples: Systematic Review,Meta‐Analysis and Meta‐Regression

Published prevalence estimates of nonsuicidal self‐injury (NSSI) among nonclinical samples are highly heterogeneous, raising concerns about their reliability and hindering attempts to explore the alleged increase in NSSI over time. Accordingly, the objectives of this study were to investigate the influence of methodological factors on heterogeneity in NSSI prevalence estimates, explore changes over time, and estimate overall international NSSI prevalence. Results showed that methodological factors contributed over half (51.6%) of the heterogeneity in prevalence estimates, and, after adjusting for these factors, NSSI prevalence did not increase over time. Overall, pooled NSSI prevalence was 17.2% among adolescents, 13.4% among young adults, and 5.5% among adults. Clearly, development of standardized methodology in NSSI research is crucial if accurate estimates are desired.     

THE EFFECTS OF SEXUALLY VIOLENT ROCK MUSIC ON MALES'ACCEPTANCE OF VIOLENCE AGAINST WOMEN

The effects of sexually violent music on undergraduate males'( N = 75) attitudes toward women, acceptance of violence against women, and self-reported sexual arousal were evaluated. The experimental manipulation involved exposure to sexually violent heavy-metal rock music, Christian heavy-metal rock music, or easy-listening classical music. One month before the experimental manipulation, participants were administered two covariate measures (religious orientation and sex-role orientation); the Attitudes toward Women Scale; the Sex-Role Stereotyping, Adversarial Sexual Beliefs, Acceptance of Interpersonal Violence, and Rape Myth Acceptance subscales from the Sexual Attitudes Survey; and a sexual arousal index. The results indicated that males with an extrinsic religious orientation were more accepting of sexist and rape-supportive beliefs. Exposure to heavy-metal rock music, irrespective of lyrical content, increased males sex-role stereotyping and negative attitudes toward women. An unexpected finding was grearer self-reported sexual arousal in response to classical music. Results are discussed with respect to participant and stimulus characteristics and experimenters'gender.

The Dialogical Subject and its Multiple and Opposing Positions

The aim of our study is to describe how the voices of others constitute the dialogical subject: an individual who is not closed off from others, but is, rather, characterized by intersubjectivity and a plurality of positions in connection with those of others. Analysis of ten semi-structured interviews carried out on members of an association supporting the right of fathers to joint custody of children shows that interviewees employed a wide variety of voices – voices in support of shared custody, but also voices which opposed it. While they most often identified with and assumed voices in favor of joint custody, they also did so with voices expressing opposing positions. Our results belie the common expectation that individuals who are committed to a cause will not be open to the opinions of others, and are incapable of seeing the world from others’ points of view.     

Bias in Conditional Inference: Implications for Mental Models and Mental Logic

Three experiments are reported in which subjects are given the opportunity to make any of the four inferences associated with conditional statements: modus ponens (MP), denial of the antecedent (DA), affirmation of the consequent (AC), and modus tollens (MT). The primary purpose of the research was to establish the generality and robustness of polarity biases that may be occasioned by systematic rotation of negative components in the conditional rules. In Experiments 1 & 2, three forms of conditionals were used: “if (not) p then (not) q”, “(not) p only if (not) q” and “(not) q if (not) p”. Experiment 1 used a conclusion evaluation task, whereas Experiment 2 used a conclusion production task. In Experiment 3, thematic conditionals were presented with and without a preceding scenario.

The biases investigated were (a) affirmative premise bias—the tendency to draw more inferences from affirmative premises and (b) negative conclusion bias—the tendency to draw more inferences with negative conclusions. The suggestive evidence for affirmative premise bias in the literature was not supported: very little evidence was found for it in the current experiments. Robust findings of negative conclusion bias were, however, found across the three experiments, although the bias was mostly restricted to DA and MT inferences. This suggests that the bias is best regarded as a difficulty with double negation.

The results are discussed with respect to both the mental logic and mental model accounts of propositional reasoning. Neither theory as currently formulated can explain all of our findings, although a plausible revision of each is considered.     

Morphological effects in children word reading: A priming study in fourth graders

A growing corpus of evidence suggests that morphology could play a role in reading acquisition, and that young readers could be sensitive to the morphemic structure of written words. In the present experiment, we examined whether and when morphological information is activated in word recognition. French fourth graders made visual lexical decisions to derived words preceded by primes sharing either a morphological or an orthographic relationship with the target. Results showed significant and equivalent facilitation priming effects in cases of morphologically and orthographically related primes at the shortest prime duration, and a significant facilitation priming effect in the case of only morphologically related primes at the longer prime duration. Thus, these results strongly suggest that a morphological level is involved in children's visual word recognition, although it is not distinct from the formal one at an early stage of word processing.
