Working memory binding of visual object features in older adults

Accurate mental representation of visual stimuli requires retaining not only the individual features but also the correct relationship between them. This associative process of binding is mediated by working memory (WM) mechanisms. The present study re-examined reports of WM-related binding deficits with aging. In Experiment 1, 31 older and 31 younger adults completed a visual change detection task with feature–location relations presented either simultaneously or sequentially; the paradigm was also designed specifically to minimize the impact of lengthy retention intervals, elaborative rehearsal, and processing demands of multi-stimulus probes. In Experiment 2, 38 older and 42 younger adults completed a modified task containing both feature–location relations and feature–feature conjunctions. In Experiment 1 although feature–location binding was more difficult with sequential compared with simultaneous presentation, the effect was independent of age. In Experiment 2 while older adults were overall slower and less accurate than young adults, there were no age-specific deficits in WM binding. Overall, after controlling for methodological factors, there was no evidence of an age-related visual WM binding deficit for surface or location features. However, unlike younger adults, older adults appeared less able to restrict processing of irrelevant features, consistent with reported declines with age in strategic capacities of WM.     

Global cognitive function before,surrounding, and after ischemic stroke: the role of risk and protective factors varies with time among ischemic stroke survivors

An estimated 65% of individuals demonstrate multidomain cognitive impairment poststroke, although little is known about the varying role of cognitive risk and protective factors in preischemic, peri-ischemic, and postischemic stroke phases. Longitudinal changes in global cognitive function after ischemic stroke are not well characterized, especially in older adults over age 80. We examined global cognitive function trajectories in these three phases across a mean follow-up of 8.12 (2.30) years in 159 female stroke survivors aged 65–79 at baseline using linear mixed models with change points. In separate models controlling for demographic variables, we tested the interaction of baseline risk and protective factors with stroke phase on global cognitive function. None of the prestroke global cognitive function means or trajectories differed significantly. At the time of ischemic stroke, higher body mass index (BMI), the presence of hypertension (HTN), low optimism, and higher physical function were all associated with significantly greater mean decreases in global cognition (all p’s <.0.0001), but were not significantly different from the contrasting level (all p’s >0.05). Higher BMI, the presence of HTN, low optimism, and higher physical function were in turn protective of global cognitive decline postischemic stroke (all contrasting p values <.01). Baseline factors may play either a risk or a protective role in global cognitive function depending on the phase of ischemic stroke.     

An Examination of Disclosure,Mental Health Treatment use,and Posttraumatic Growth Among College Women Who Experienced Sexual Victimization

Few investigations have sought to identify factors associated with posttraumatic growth among survivors of sexual victimization. The present study examined the relationship between posttraumatic growth, disclosure, and mental health treatment use following sexual assault. Undergraduate female psychology students (N = 85), who reported a prior history of sexual victimization, completed measures assessing trauma exposure, posttraumatic growth, disclosure, and mental health treatment use. Results revealed that degree of disclosure of the assault to support sources and mental health treatment use following sexual assault was related to increased posttraumatic growth. Findings have valuable implications for treatment interventions for survivors of sexual trauma.     

Changes in Female Rape Myth Acceptance Among College Students: A 20-Year Perspective

In this study, we compared changes in female rape myth acceptance (RMA) between 1998 and 2018 in two separate samples of college students from the same university in the U.S. Pacific Northwest. The primary measure was the Attitudes Toward Rape Victims Scale (ARVS). First, we examined the factor structure of the ARVS with confirmatory factor analysis, finding good fit for a four-factor model comprising Assigning Blame or Responsibility to the Victim (Blame/Responsibility), Considering the Victim as Deserving of Sexual Violence (Deserving), Undermining the Victim’s Credibility (Undermine Credibility), and Trivializing the Experience or Denigrating the Victim (Trivialization/Denigration). Second, we used profile analysis, a type of multivariate repeated-measures ANOVA, to examine the main and interactive effects of Survey Year, Gender, and ARVS Subscale and Item within each subscale. At the subscale level, we found large main effects for Survey Year, Gender, and Subscale, with lower scores for the 2018 sample, women, and Deserving and Trivialization/Denigration, relative to Undermine Credibility and Blame/Responsibility. We also found interactions between Survey Year and Subscale and Gender and Subscale, indicating non-parallel profiles for the 1998 versus 2018 samples and women versus men. We found similar patterns at the item level within each subscale. These results indicate a substantial decline of female RMA in college students over a 20-year period, replicate the well-established gender difference in female RMA, and demonstrate that RMA varies by item content.

     

Visual search for drowning swimmers: Investigating the impact of lifeguarding experience

How does domain expertise influence dynamic visual search? Previous studies of visual search often use abstract search arrays that are devoid of applied context, with comparatively few studies exploring applied naturalistic and dynamic settings. The current research adds to this literature by examining lifeguard drowning‐detection across two studies using naturalistic, dynamic search tasks. Behavioural responses and eye‐movement data were recorded as participants watched staged video clips and attempted to identify if a swimmer was drowning. The results demonstrate lifeguard superiority in response times to drowning events, compared to non‐lifeguards. No differences between lifeguard and non‐lifeguard eye‐movements were noted however. This suggests that the experiential benefit in response times results from other underlying processes, rather than any scanning benefits. This research highlights the complex nature of naturalistic and dynamic searches, while demonstrating the robust nature of simulated videos in producing experience effects in visual search.     

The Relationship between Intimate Partner Violence and Suicidal Ideation among Young Chinese,Korean, and Vietnamese American Women

ABSTRACT

High depression and suicide rates are critical problems that have a significant impact on the lives of young Asian American women. Intimate partner violence (IPV) has been identified as a predictor of suicidality in general female samples, but no research study has examined the relationship between IPV and suicidality in a sample of 1.5 and second-generation Chinese, Korean, and Vietnamese American women. We used data collected from 173 women (aged 18-35 years) who were screened for eligibility to participate in the development and efficacy study of Asian American Women’s Action for Resilience and Empowerment (AWARE). We measured the prevalence of (a) IPV, (b) lifetime suicidal ideation/intent, and (c) childhood abuse and tested the association between IPV and lifetime suicidal ideation/intent among study participants who completed the clinical screening assessments. The results indicated that seven out of 10 women in our sample experienced lifetime suicidal ideation/intent, psychological aggression was the most commonly reported form of IPV during the last six months, followed by sexual coercion, and history of physical and/or sexual partner violence had the most robust association with lifetime suicidal ideation/intent after controlling for demographic factors and childhood abuse. Our study suggests that suicide prevention and intervention programs for young 1.5 and second-generation Asian American women should not only address experiences of childhood abuse, but also incorporate culturally adapted behavioral health approaches to identify and target physical and sexual partner violence. Furthermore, any such programs need to integrate a systemic approach in addressing IPV within the context of various marginalized experiences of Asian American women.

Integrative approaches to couple therapy: implications for clinical practice and research

Although meta-analyses affirm that various treatments for couple distress produce statistically and clinically significant outcomes, research findings also indicate that a large percentage of couples fail to benefit or subsequently deteriorate following current therapies. Based on these findings, we advocate potential advantages of integrative approaches to couple therapy. We distinguish among assimilative, transtheoretical, and pluralistic approaches to integration and describe exemplars of each. Integrative approaches to couple therapy are compared to distillatory or common factors approaches emphasizing common elements of treatment components, therapist characteristics, and client or relationship attributes. We argue that clinical practice of integrative approaches to couple therapy requires conceptual and clinical decision-making skills transcending those of any one theoretical modality and emphasizing the selection, sequencing, and pacing of diverse interventions in a coherent manner. We conclude with implications of integrative couple-based treatments for future research.
