Racial identity and sense of belonging: Moderators of Black college students' institutional race-related stress and anxious arousal.

OBJECTIVES: Race-related stress due to institutional racism is a pervasive reality for Black college students and contributes to poor mental health outcomes such as anxious arousal symptoms. One framework which may account for this association between chronic stress and anxious arousal symptoms is the reserve capacity model. This study investigated whether racial identity dimensions (racial centrality, public regard, private regard) and sense of belonging to the racial group contribute to this population's reserve capacity and buffer the association between institutional race-related stress and anxious arousal symptoms. METHOD: A sample of 134 Black college students completed racial identity, sense of belonging, and mental health questionnaires. These data were subjected to multiple regression analysis to assess the main and interactive effects of institutional race-related stress and dimensions of interest as predictors of anxious arousal symptoms. RESULTS: The analysis indicated that higher levels of institutional race-related stress, racial centrality, and public regard were each associated with higher levels of anxious arousal while higher levels of private regard and sense of belonging were associated with lower levels of anxious arousal. Further investigation of interaction effects revealed that high levels of sense of belonging and low levels of public regard, respectively, buffered the association between institutional race-related stress and anxious arousal symptoms. CONCLUSIONS: These findings illustrate how certain racial identity dimensions and sense of belonging contribute to the reserve capacity of Black students experiencing institutional race-related stress. Results are further discussed in the context of extant literature on Black racial identity and the university context. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Aging is associated with maladaptive episodic memory-guided social decision-making.

Older adults are frequent targets and victims of financial fraud. They may be especially susceptible to revictimization because of age-related changes in both episodic memory and social motivation. Here we examined these factors in a context where adaptive social decision-making requires intact associative memory for previous social interactions. Older adults made more maladaptive episodic memory-guided social decisions but not only because of poorer associative memory. Older adults were biased toward remembering people as being fair, while young adults were biased toward remembering people as being unfair. Holding memory constant, older adults engaged more with people that were familiar (regardless of the nature of the previous interaction), whereas young adults were prone to avoiding others that they remembered as being unfair. Finally, older adults were more influenced by facial appearances, choosing to interact with social partners that looked more generous, even though those perceptions were inconsistent with prior experience.

Links between autobiographical memory richness and temporal discounting in older adults.

When making choices between smaller, sooner rewards and larger, later ones, people tend to discount future outcomes. Individual differences in temporal discounting in older adults have been associated with episodic memory abilities and entorhinal cortical thickness. The cause of this association between better memory and more future-oriented choice remains unclear, however. One possibility is that people with perceptually richer recollections are more patient because they also imagine the future more vividly. Alternatively, perhaps people whose memories focus more on the meaning of events (i.e., are more "gist-based") show reduced temporal discounting, since imagining the future depends on interactions between semantic and episodic memory. We examined which categories of episodic details - perception-based or gist-based - are associated with temporal discounting in older adults. Older adults whose autobiographical memories were richer in perception-based details showed reduced temporal discounting. Furthermore, in an exploratory neuroanatomical analysis, both discount rates and perception-based details correlated with entorhinal cortical thickness. Retrieving autobiographical memories before choice did not affect temporal discounting, however, suggesting that activating episodic memory circuitry at the time of choice is insufficient to alter discounting in older adults. These findings elucidate the role of episodic memory in decision making, which will inform interventions to nudge intertemporal choices.
