The mediating effect of reflective-analytic cognitive style on rational thought

Abstract

We investigate whether non-miserly cognitive styles mediate the effects of cognitive ability and thinking dispositions on rational thought. Specifically, we review relevant literature on two dimensions that define non-miserly cognitive style: reflection-impulsivity and analytic-intuitive. We use these two dimensions to identify a continuum of cognitive styles that vary from miserly (impulsive-intuitive) to non-miserly (reflective-analytic) and are congruent with tendencies to commit specific rational thinking errors. Further, we argue that this continuum, which we label reflective-analytic cognitive style, mediates the effect of cognitive ability and thinking dispositions on rational thought. We conduct an experiment testing our predictions and find evidence, via structural equation modelling, that reflective-analytic cognitive style does mediate the effect of cognitive ability (as measured by working memory capacity) and thinking dispositions (as measured by need for cognition and actively open-minded thinking) on responses to traditional rational thinking tasks.     

Social Responsiveness and Objectification: The Moderating Roles of Serotonin Transporter and Serotonin Receptor 2A Genotypes in an Objectification Theory Model of Disordered Eating

Feminist scholars have called for gender researchers to consider gene-environment interactions for gender-imbalanced disorders (Salk and Hyde Psychology of Women Quarterly, 36, 395–411, 2012). Responding to these calls, the present study integrates objectification theory (Fredrickson and Roberts Psychology of Women Quarterly, 21, 173–206, 1997) and genetic research. In the tested model, objectification experiences are associated with disordered eating through body surveillance and body shame, and serotonin transporter (SLC6A4) genotypes (5-HTTLPR and rs25531), serotonin 2A receptor SNP genotypes (HTR2A rs6311), and the epistatic interaction between those genotypes function as moderators. U.S. undergraduate women (n?=?526) completed self-reports of objectification, body surveillance, body shame, and disordered eating and donated buccal cells for genetic analyses. The association between objectification and disordered eating was mediated by body shame, but not body surveillance. The paths from objectification to both body surveillance and body shame were moderated by genotypes. The indirect effect of objectification on disordered eating through body shame was only present for SLC6A4 L′ and rs6311 G homozygotes. Our results are consistent with previous evidence that serotonin system genetic variation is associated with disordered eating risk. They provide evidence of a non-deterministic genetic effect that is context-dependent and subtle. These findings also reinforce efforts to develop personalized prevention and treatment approaches for eating disorders.

     

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.
