S. and in Colombia, among adolescents and adults, and among male and female respondents. We also found that negative context of reception scores was associated with elevated scores on criterion-related factors-that is, perceived discrimination and depressive symptoms-in ways that are theoretically coherent and support measure validity.

We provide new evidence that the Perceived Negative Context of Reception scale is reliable and valid for use with Venezuelan immigrants in the U.S. and Colombia. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

The use of fNIRS in community-based research may (a) advance theoretical knowledge in psychology and neuroscience, particularly regarding underrepresented ethnic-racial communities; (b) increase diversity in samples; and (c) provide neurobiological evidence of sociocultural factors supporting human development. The review aims to introduce the use of fNIRS, including its practicalities and limitations, to new adopters inquiring how sociocultural inputs affect the brain. EPZ005687 chemical structure The review begins with an introduction to cultural neuroscience, and a review on the use of fNIRS follows. Next, benefits and guidelines to the design of fNIRS research in naturalistic environments (in the community or in the field) using a cultural lens are discussed. Strengths-based and community-based approaches in cultural neuroscience are recommended throughout.

Higher rates of lifetime trauma exposure are strongly associated with subsequent psychological sequela, specifically depression and posttraumatic stress disorder (PTSD). Communal mastery is the ability to cope with challenges and achieve goals by being closely interconnected with friends, family, and significant others. Yet, it is unknown if communal mastery is protective specifically against PTSD and depressive symptoms. Method Participants (N = 131) were Black and Latina women (88.5% Black, mean monthly income less then $750) recruited from an urban outpatient obstetric-gynecological clinic at an academic medical center. Participants completed an online questionnaire that assessed trauma history, PTSD and depressive symptoms, types of individualistic coping, social support, and communal mastery. Results Hierarchical multiple regression models demonstrated that communal mastery is uniquely associated with fewer PTSD symptoms (β = -.23, p = .003). More severe trauma history, more use of passive coping skills, and poorer social support were also significantly associated with PTSD symptoms, explaining over half of the variance in PTSD symptoms. Although significantly correlated, communal mastery was not uniquely associated with fewer depressive symptoms (β = -.13, p = .201). Conclusions These findings suggest that connectedness as assessed through communal mastery serves as an important shield against the effects of traumatic stress for Black and Latina women. Future research would benefit by exploring interventions that aim to increase communal mastery in order to help highly trauma-exposed racial and ethnic minority women in low-resource environments.

One key prerequisite for model-based decision-making is learning the transition structure of the environment-the probabilities of transitioning from one environmental state to another. In this work, we investigated how the OFC might be involved in learning this transition structure, by using fMRI to assess OFC activity while humans experienced probabilistic cue-outcome transitions. We found that OFC activity was indeed correlated with behavioral measures of learning about transition structure. On a trial-by-trial basis, OFC activity was associated with subsequently increased expectation of the more probable outcome; that is, with subsequently more optimal cue-outcome predictions. Interestingly, this relationship was observed no matter what outcome occurred at the time of the OFC activity, and thus is inconsistent with an interpretation of the OFC activity as representing a "state prediction error" that would facilitate learning transitions via error-correcting mechanisms. Finally, OFC activity was related to more optimal predictions only for subsequent trials involving the same cue that was observed at the time of OFC activity-this relationship was not observed for subsequent trials involving a different cue. All together, these results indicate that the OFC is involved in updating or reinforcing a learned transition model on a trial-by-trial basis, specifically for the currently observed cue-outcome associations.

Gaining this knowledge may foster the know-how on their role in subsequent task-engagement and also on the interlinkage among affective measures and approach/withdrawal dichotomy. Here we performed a study based on Region of Interest (ROI)-based analysis and graph-theory estimates for global and subnetworks on a limited sample of healthy 50 male volunteers who recorded resting functional magnetic resonance imaging (fMRI) and self-reported measures of Positive and Negative Affect Schedule (PANAS) and BAS-BIS (Behavioral Activation System-Behavioral Inhibition System) scores. Our study's initial results of region of interest-to-region of interest (ROI-to-ROI) connectivity revealed the connectivity of subcortical neural substrates of PANAS and BAS-BIS scores with bilateralized cortical regions. However, on probing the lateralization of strength of degree measures of the cortical-regions vital for subcortical-cortical interaction, we found, for positive affect, a left-hemispheric proclivity.
