Repeated study of items with and without repeated context: aging effects on memory discriminability

Presenting items multiple times during encoding is a common way to enhance recognition accuracy. Under such conditions, older adults often show an increase in false recognition that counteracts benefits of repeated study. Using a false-memory paradigm with related study items and related lures, we tested whether repetition within the same encoding task or repetition across two different encoding tasks would be more beneficial to older adults’ memory discriminability. Results showed that, compared to items not repeated at study, items repeated in the same context and items repeated across different contexts showed improvements in memory discriminability in both young and older adults. This improvement was primarily reflected in improved recollection responses for both age groups across both repeat study conditions, as compared to no repetition. Importantly, the results demonstrated that repetition can be used to successfully mitigate age-related deficits by increasing memory discriminability and without incurring a cost of false recognition specific to any one age group.     

Interpretation Bias Training in Depressed Adolescents: Near- and Far-Transfer Effects

Depressed adolescents are characterized by negative interpretation biases. Although investigators have used cognitive bias modification for interpretation (CBM-I) to experimentally manipulate interpretation biases in depressed adults, the near- and far-transfer effects are not well understood in adolescents diagnosed with Major Depressive Disorder (MDD). In this study, we extend previous research by investigating the near- and far-transfer effects of 6 sessions of Positive versus Neutral CBM-I on independent measures of interpretation bias (near-transfer effects) and on attention biases and clinical symptoms (far-transfer effects) in a sample of adolescents with MDD (n = 46). At post-training, adolescents who received Positive CBM-I interpreted ambiguous scenarios more positively than did participants who received Neutral CBM-I, providing evidence of training effectiveness. There was no evidence, however, of near- or far-transfer effects. These findings raise concerns about the malleability of interpretation biases in adolescent depression and suggest that further work is needed to establish the clinical utility of CBM-I for adolescents with MDD.     

Recommendations to disclose sexual assault are motivated by retribution among women who endorse honor values

Rape arrests are higher in US states wherein residents more typically endorse honor values. Because honor values reflect an association between reputation and self-worth, which is based on one's ability to uphold traditional gender norms, one should expect that women who endorse honor values are motivated to conceal a sexual assault. However, honor values also engender the expectation that women defend their reputations if threatened. Thus, women from honor cultures should be more likely to seek retribution by disclosing a sexual assault to others. The current research investigates the impact of honor values on the recommendation to disclose a sexual assault when women believe the victim is motivated to protect her reputation. We evaluated the role of common post-rape emotions (shame, anger, and fear) on motivations to either conceal a “victim” status or to punish the transgression. In two studies, US women (total n = 842) responded to vignettes of sexual assault that varied the relationship of the perpetrator (acquaintance or husband). Using path modeling to test the two competing hypotheses, we found that women who endorsed honor values more strongly perceived that the victim of a sexual assault experienced more anger and fear, was more likely to seek retribution, and, in turn, were more likely to recommend that she disclose to confidants (similar across the acquaintance and husband scenarios). These findings may help increase researchers' and practitioners' cultural understanding of the help-seeking behavior of survivors of sexual assault across different communities.     

Stigma,Expressed Emotion,and Quality of Life in Caregivers of Individuals with Dementia

Expressed emotion (EE) is a measure of a caregiver's critical and emotionally overinvolved (EOI; e.g., intrusive, self‐sacrificing) attitudes and behaviors toward a person with a mental illness. Mounting evidence indicates that high levels of these critical and EOI attitudes and behaviors (collectively termed high EE) in family members are associated with a poorer course of illness for people with a range of disorders, including dementia (Nomura et al., 2005). However, less is known about factors that might trigger high EE and how high EE might impact dementia caregivers’ own mental health. In this study we propose that caregivers who perceive stigma from their relative's illness may be more likely to be critical or intrusive (high EOI) toward their relative in an attempt to control symptomatic behaviors. We further hypothesized that high EE would partially mediate the link between stigma and quality of life (QoL) as there is some evidence that high EE is associated with poorer mental health in caregivers themselves (Safavi et al., 2015). In line with study hypotheses and using a sample of 106 dementia caregivers, we found that greater caregiver stigma was associated with both high EE (for criticism and EOI) and with poorer QoL. Mediational analyses further confirmed that high EE accounts for much of the association between stigma and poorer QoL. Study results suggest that addressing caregiver stigma in therapy could reduce levels of high EE and indirectly therefore improve caregiver QoL. Intervening directly to reduce high EE could also improve caregiver QoL.     

Age-related similarities and differences in monitoring spatial cognition

Spatial cognitive performance is impaired in later adulthood but it is unclear whether the metacognitive processes involved in monitoring spatial cognitive performance are also compromised. Inaccurate monitoring could affect whether people choose to engage in tasks that require spatial thinking and also the strategies they use in spatial domains such as navigation. The current experiment examined potential age differences in monitoring spatial cognitive performance in a variety of spatial domains including visual–spatial working memory, spatial orientation, spatial visualization, navigation, and place learning. Younger and older adults completed a 2D mental rotation test, 3D mental rotation test, paper folding test, spatial memory span test, two virtual navigation tasks, and a cognitive mapping test. Participants also made metacognitive judgments of performance (confidence judgments, judgments of learning, or navigation time estimates) on each trial for all spatial tasks. Preference for allocentric or egocentric navigation strategies was also measured. Overall, performance was poorer and confidence in performance was lower for older adults than younger adults. In most spatial domains, the absolute and relative accuracy of metacognitive judgments was equivalent for both age groups. However, age differences in monitoring accuracy (specifically relative accuracy) emerged in spatial tasks involving navigation. Confidence in navigating for a target location also mediated age differences in allocentric navigation strategy use. These findings suggest that with the possible exception of navigation monitoring, spatial cognition may be spared from age-related decline even though spatial cognition itself is impaired in older age.     

Integrative perspectives on acculturation

Comments on the original article, "Rethinking the concept of acculturation: Implications for theory and research," by S. J. Schwartz, J. B. Unger, B. L. Zamboanga, and J. Szapocznik (see record 2010-08987-001). Schwartz et al are to be commended for their attempts "to propose an expanded, multidimensional model of acculturation and of the demographic and contextual forces that can influence the acculturation process" (p. 238). In their article, they called attention to key factors such as the generational status of immigrants and their children; the role of location, particularly in ethnic enclaves; and the context of reception that immigrants enter, including the potential discrimination they may face. These variables are the crucial backdrop for the authors' call to "focus on the higher order construct of receiving-culture acquisition as well as on the individual dimensions of this higher order construct-practices, values, and identifications" (p. 246). As a sociologist trained in social psychology, I am pleased by their incorporation of some of the sociological literature on these processes. However, I was surprised by important gaps in their discussion of Portes and Rumbaut's (1996, 2006) work and by their neglect of one of the most widely used terms employed by sociologists to hypothesize outcomes for the very questions Schwartz et al were posing.     

Introducing Spirituality into Psychiatric Care

Spirituality is important to many psychiatric patients, and these patients may be moved toward recovery more effectively if their spiritual needs are addressed in treatment. This, however, is rarely given expression in the psychiatric services of teaching hospitals. In order to develop this potential area of improved care, we (1) evaluated the differential attitudes of patients and psychiatric trainees toward the value of spirituality in the recovery process, (2) established a program of group meetings conducted by psychiatric residents and staff where patients can discuss how to draw on their spirituality in coping with their problems, and (3) established related training experiences for psychiatric residents. The results and implications of these three initiatives are presented.
