Racial prejudice is associated with a fundamental distinction between “us” and “them”—a distinction linked to the perceived overlap between representations of the self and others. Implicit prejudice has been shown to reduce the intensity of White individuals’ hand ownership sensation as induced by the Rubber Hand Illusion (RHI) with dark rubber hands. However, evidence for this link to implicit prejudice comes from self-report questionnaire data regarding the RHI. As an alternative, we assessed the onset time of the RHI. We hypothesized that onset time of the RHI would be higher for the black compared to the white RH, acting as the mediator between implicit prejudice and magnitude of the RH illusion and proprioceptive drift. As expected, participants took longer to incorporate the black RH and presented lower RH illusion magnitude and a smaller proprioceptive drift for the black RH. Mediation analysis revealed a significant indirect effect of implicit racial bias on proprioceptive drift and magnitude of illusion through onset time to illusion only for the black RH. These findings further illuminate the connection between implicit prejudice and embodied perception, suggesting new perspectives on how implicit biases operate.

the biggest difficulties were dealing with relapses, and the lack of public resources. Religiosity and faith, isolation and advice were used as coping strategies; ambivalence in thoughts and attitudes was demonstrated.

This study examined the factor structure of the Brazilian version of the Autism-Spectrum Quotient. This is a self-report questionnaire for continuous and quantitative assessment of autistic spectrum traits in adults. Confirmatory factor analysis was performed on the five-factor model (social skill, attention switching, attention to detail, communication and imagination) proposed by the original authors, support not being found for this model in our sample. An exploratory factor analysis was then performed that resulted in an alternative three-factor model (social skills, details/patterns and imagination). Confirmatory factor analysis of the latter model revealed adequate psychometric indexes. The Brazilian version of the AQ was shown to be an adequate instrument for the evaluation of signs compatible with the autism spectrum in adults.

The ultimatum game (UG) is an endowment sharing game in which a proposer suggests a division of an asset to a recipient, who must accept or reject it. Economic studies showed that despite recipients usually rejecting unfair offers, perception and reaction to unfairness are highly dependent on who is the proposer. Event-related potentials (ERPs) commonly detected in UG games are the medial frontal negativity (MFN), a component detected in recipients facing unfair offers, and the P300, a component related to attentional and memory processes. Given this, we aimed to investigate the behavioral and ERP responses of healthy people playing the UG game with Down syndrome (DS) and typical development (TD) proposers. Nineteen subjects participated in this study. The UG behavioral data were similar to previous studies. ERP analysis showed no MFN in participants facing unfair offers. A higher P300 amplitude was detected when participants faced fair offers from TD compared to DS fair offers. We also found a positive correlation between P300 amplitude for TD offers and self-esteem scale score. Together these findings indicate that insertion of an atypical player in the UG led to changes in participants' perception and expectancy of the game.

Research on racial bias in social and cognitive psychology has focused on automatic cognitive processes such as categorisation or stereotyping. Neuroimaging has revealed differences in the neural circuit when processing social information about one’s own or another’s ethnicity. This review investigates the influence of racial bias on human behaviour by reviewing studies that examined changes in neural circuitry (i.e. ERP responses) during automatic and controlled processes elicited by specific tasks. This systematic analysis of specific ERP components across different studies provides a greater understanding of how social contexts are perceived and become associated with specific stereotypes and behavioural predictions. Therefore, investigating these related cognitive and neurobiological functions can further our understanding of how racial bias affects our cognition more generally and guide more effective programs and policies aimed at its mitigation.

Background Health professionals treating sexual dysfunction and relational dissatisfaction recognize that they are multifactorial phenomena, and depression can be bidirectionally associated with both. Aim The purpose of this study was to investigate sexual dysfunction in heterosexual couples in relation to the quality of their marital relationship and depression symptoms. Methods The sample consisted of 100 heterosexual couples recruited in Brazil. Both partners of each couple completed the Golombok-Rust Inventory of Sexual Satisfaction and the Golombok-Rust Inventory of Marital Satisfaction, which were translated and adapted, and the Beck Depression Inventory, which was validated for the Brazilian population. Both partners completed their questionnaires separately, and the couple’s surveys were linked to preserve conjugal data for dyadic analysis. The Actor-Partner Interdependence Model was used to understand how sexual dysfunction in couples is related to depression and relationship quality among and between partners. Results Sexual dysfunction was found to be strongly associated with dissatisfaction in the relationship (husbands, β = 0.57, P < 0.001; wives, β = 0.60, P < 0.001), and a positive association was found between depressive symptoms and marital dissatisfaction (husbands, β = .32, P < .001; wives β = .40, P < .001). Clinical Implication The results suggest that it is important for health professionals to be aware of the dyadic impact of struggles with both sex and the relationship and the presence of depression symptoms in patients who seek care for sexual complaints or depression and who are in a marital relationship. Strengths and Limitations The different results found for men and women may shed light on the biopsychosocial dimensions of human sexuality. When treated as a purely physical experience, sex is myopic. In this study we demonstrated psychosocial aspects associated with gender and sexuality, and the partner’s variables were found to have a greater impact on women than they did on the men. A limitation of this study is that the sample is not generalizable as it is not demographically representative of all socioeconomic groups in Brazil. Furthermore, the participants in this sample did not have clinical levels of depression, so the results cannot be extended to couples in which one or both spouses have depressive disorder. Conclusion It was found that sexual dysfunction is strongly associated with the quality of the couple relationship, and that the quality of relationship plays a mediating role between depression and marital quality, especially for the women.
