RESUMO

ACADEMIC ABSTRACT: How do social stereotypes shape and reflect images formed in the mind's eye? Visual mental imagery has long been assumed crucial in creating, maintaining, and perpetuating stereotypes and prejudice. Surprisingly, research in social cognition has only recently begun to explore the causal role of mental images in these phenomena. In contrast, cognitive neuroscience research on visual mental imagery (VMI) has explored the pivotal role of imagery in various consequential cognitive and behavioral phenomena. However, cognitive neuroscience has largely neglected how stereotypes influence mental imagery. This article provides a historical overview of the development of these two fields in terms of mental imagery and discusses recent advances at their intersection. Opportunities for additional integration are highlighted, and suggestions for furthering the dual study of stereotyping and mental imagery are provided. PUBLIC ABSTRACT: How can social stereotypes impact and mirror visual imagination? It has long been assumed that visual mental imagery plays a central role in forming, maintaining, and strengthening stereotypes and prejudice. Yet, until recently, there has been limited exploration within social psychology and cognitive neuroscience on the explicit connection between visual mental images and social stereotypes. We describe the historical progression of these fields concerning visual imagery and explore recent advancements that unite stereotyping and mental imagery research. Furthermore, we propose avenues for future research to deepen our understanding of how individuals utilize mental images in stereotyping and how mental imagery can modify stereotypes.

RESUMO

Theories of Visual Mental Imagery (VMI) emphasize the processes of retrieval, modification, and recombination of sensory information from long-term memory. Yet, only few studies have focused on the behavioral mechanisms and neural correlates supporting VMI of stimuli from different semantic domains. Therefore, we currently have a limited understanding of how the brain generates and maintains mental representations of colors, faces, shapes - to name a few. Such an undetermined scenario renders unclear the organizational structure of neural circuits supporting VMI, including the role of the early visual cortex. We aimed to fill this gap by reviewing the scientific literature of five semantic domains: visuospatial, face, colors, shapes, and letters imagery. Linking theory to evidence from over 60 different experimental designs, this review highlights three main points. First, there is no consistent activity in the early visual cortex across all VMI domains, contrary to the prediction of the dominant model. Second, there is consistent activity of the frontoparietal networks and the left hemisphere's fusiform gyrus during voluntary VMI irrespective of the semantic domain investigated. We propose that these structures are part of a domain-general VMI sub-network. Third, domain-specific information engages specific regions of the ventral and dorsal cortical visual pathways. These regions partly overlap with those found in visual perception studies (e.g., fusiform face area for faces imagery; lingual gyrus for color imagery). Altogether, the reviewed evidence suggests the existence of domain-general and domain-specific mechanisms of VMI selectively engaged by stimulus-specific properties (e.g., colors or faces). These mechanisms would be supported by an organizational structure mixing vertical and horizontal connections (heterarchy) between sub-networks for specific stimulus domains. Such a heterarchical organization of VMI makes different predictions from current models of VMI as reversed perception. Our conclusions set the stage for future research, which should aim to characterize the spatiotemporal dynamics and interactions among key regions of this architecture giving rise to visual mental images.

RESUMO

OBJECTIVE: LGBTQ-affirmative cognitive-behavioral therapy (CBT) addresses minority stress to improve sexual minority individuals' mental and behavioral health. This treatment has never been tested in high-stigma contexts like China using online delivery. METHOD: Chinese young sexual minority men (n = 120; ages 16-30; HIV-negative; reporting depression and/or anxiety symptoms and past-90-day HIV-transmission-risk behavior), were randomized to receive 10 sessions of culturally adapted asynchronous LGBTQ-affirmative internet-based CBT (ICBT) or weekly assessments only. The primary outcome included HIV-transmission-risk behavior (i.e., past-30-day condomless anal sex). Secondary outcomes included HIV social-cognitive mechanisms (e.g., condom use self-efficacy), mental health (e.g., depression), and behavioral health (e.g., alcohol use), as well as minority stress (e.g., acceptance concerns), and universal (e.g., emotion regulation) mechanisms at baseline and 4- and 8-month follow-up. Moderation analyses examined treatment efficacy as a function of baseline stigma experiences and session completion. RESULTS: Compared to assessment only, LGBTQ-affirmative ICBT did not yield greater reductions in HIV-transmission-risk behavior or social-cognitive mechanisms. However, LGBTQ-affirmative ICBT yielded greater improvements in depression (d = -0.50, d = -0.63) and anxiety (d = -0.51, d = -0.49) at 4- and 8-month follow-up, respectively; alcohol use (d = -0.40) at 8-month follow-up; and certain minority stress (e.g., internalized stigma) and universal (i.e., emotion dysregulation) mechanisms compared to assessment only. LGBTQ-affirmative ICBT was more efficacious for reducing HIV-transmission-risk behavior for participants with lower internalized stigma (d = 0.42). Greater session completion predicted greater reductions in suicidality and rumination. CONCLUSIONS: LGBTQ-affirmative ICBT demonstrates preliminary efficacy for Chinese young sexual minority men. Findings can inform future interventions for young sexual minority men in contexts with limited affirmative supports.

RESUMO

Purpose: Transgender and nonbinary (TNB) populations experience disproportionate rates of sexual assault. Despite evidence from cisgender samples linking sexual assault exposure to body image concerns and disordered eating behaviors, such as weight and shape control behaviors (WSCBs), little is known about these relationships in TNB people. The purpose of this study was to assess associations among past-year sexual assault exposure, body areas satisfaction, body weight esteem, and high-risk WSCBs in a sample of TNB young adults. Methods: A sample of 714 participants completed a cross-sectional online survey. Multivariable linear and logistic models were fit to determine associations between constructs of interest. Natural effects mediation analyses assessed for potential mediation of the relationship between sexual assault and WSCBs by body areas satisfaction and body weight esteem. Analyses were stratified by three gender identity categories. Results: Past-year sexual assault exposure was associated with significantly decreased body areas satisfaction, but only for nonbinary participants. No significant association was found between sexual assault and body weight esteem. Sexual assault was associated with significantly increased risk for WSCBs across gender identity categories. No mediation of these relationships by body areas satisfaction and body weight esteem was observed. Conclusion: Findings support clinical consideration of WSCBs in TNB survivors of sexual assault. Results suggest that multiple factors, including body image and sexual assault, may contribute separately to disordered eating behaviors in TNB young adults.

RESUMO

OBJECTIVE: LGBTQ-affirmative cognitive-behavioral therapy (CBT) addresses the adverse impacts of minority stress. However, this treatment has rarely been tested in randomized controlled trials with LGBTQ youth and never using an asynchronous online platform for broad reach. This study examined the feasibility, acceptability, preliminary efficacy, and multi-level stigma moderators of LGBTQ-affirmative internet-based CBT (ICBT). METHOD: Participants were 120 LGBTQ youth (ages 16-25; 37.5% transgender or non-binary; 75.8% assigned female at birth; 49.2% non-Latino White) living across 38 U.S. states and reporting depression and/or anxiety symptoms. Participants were randomized to receive 10 sessions of LGBTQ-affirmative ICBT or only complete 10 weekly assessments of mental and behavioral health and minority stress; all completed measures of psychological distress, depression, anxiety, suicidal thoughts, alcohol use, and HIV-transmission-risk behavior at baseline and 4 and 8 months post-baseline; 20 LGBTQ-affirmative ICBT participants completed a qualitative interview regarding intervention acceptability. RESULTS: Participants randomized to LGBTQ-affirmative ICBT completed, on average, 6.08 (SD = 3.80) sessions. Participants reported that LGBTQ-affirmative ICBT was helpful and engaging and provided suggestions for enhancing engagement. Although most outcomes decreased over time, between-group comparisons were small and non-significant. LGBTQ-affirmative ICBT was more efficacious in reducing psychological distress than assessment-only for participants in counties high in anti-LGBTQ bias (b = -1.73, p = 0.001, 95% CI [-2.75, -0.70]). Session dosage also significantly predicted reduced depression and anxiety symptoms. CONCLUSIONS: LGBTQ-affirmative ICBT represents a feasible and acceptable treatment. Future research can identify more efficacious approaches and modalities for engaging LGBTQ youth, especially those living under stigmatizing conditions, who might benefit most.
