THE EFFECTS OF CHILDHOOD FAMILY STRESS ON WOMEN'S DEPRESSIVE SYMPTOMS:

This study uses a life course approach to observe the interaction between stressful childhood events and recent undesirable events to predict depressive symptoms in women. Data are from a community sample ( N = 205) of adult daughters from the Cornell Women's Roles Project, aged 26–58 years. Results indicate that women who experienced mild stressors during childhood are less likely to have depressive responses to undesirable events than are those who did not have stressful family backgrounds. This buffering influence appears to be partially mediated through a woman's belief in her control over external events. In the absence of childhood strains, a close father–daughter relationship during childhood may also teach women protective mastery skills. Overall, findings suggest that women's differing depressive responses to undesirable events follow a developmental pathway beginning with early childhood experiences. We suggest that the milder childhood stressors measured in this study stimulated an adaptive family environment from which these women were able to garner life course coping strategies.     

Closing the Gap in Aboriginal and Torres Strait Islander Youth Suicide: A Social–Emotional Wellbeing Service Innovation Project

Objective

The suicide rate for Queensland's Aboriginal and Torres Strait Islander young people is over four times that of their non‐Indigenous counterparts, with Aboriginal and Torres Strait Islander children (under 15) dying by suicide at 12 times the non‐Indigenous rate. There is a need for interventions that are culturally validated and community‐endorsed. The aim of this article is to describe the design and implementation of a group‐based intervention, as well to report the results of the various qualitative and quantitative measures.

Method

Sixty‐one Aboriginal and Torres Strait Islander persons aged 11–21 years completed a social–emotional wellbeing (SEWB) program at headspace Inala. Data were available through to 2‐month follow‐up for 49 participants. The program was designed and delivered in collaboration with the local Aboriginal and Torres Strait Islander community.

Results

There was a statistically significant decrease in suicidal ideation experienced by the participants after completing the program. Qualitative measures indicated that participants experienced improved understanding of holistic health and an increased number of coping skills.

Conclusions

Not only was this the first evaluated intervention in Aboriginal and Torres Strait Islander youth to ever report a decrease in individual suicidality, the program was carefully designed and implemented in consultation with community in a culturally sensitive manner and thus provides an invaluable framework for future SEWB work.     

A Sense of Powerlessness Fosters System Justification: Implications for the Legitimation of Authority,Hierarchy, and Government

In an attempt to explain the stability of hierarchy, we focus on the perspective of the powerless and how a subjective sense of dependence leads them to imbue the system and its authorities with legitimacy. In Study 1, we found in a nationally representative sample of U.S. employees that financial dependence on one's job was positively associated with the perceived legitimacy of one's supervisor. In Study 2, we observed that a general sense of powerlessness was positively correlated with the perceived legitimacy of the economic system. In Studies 3 and 4, priming experimental participants with feelings of powerlessness increased their justification of the social system, even when they were presented with system‐challenging explanations for race, class, and gender disparities. In Study 5, we demonstrated that the experience of powerlessness increased legitimation of governmental authorities (relative to baseline conditions). The processes we identify are likely to perpetuate inequality insofar as the powerless justify rather than strive to change the hierarchical structures that disadvantage them.     

Perceived Norms,Outcome Expectancies,and Collegiate Drinking: Examining the Mediating Role of Drinking Motives

The authors examined the mediational role of drinking motives in explaining the associations among psychosocial antecedents and collegiate drinking. Results indicated that drinking motives partially mediated the relationships between outcome expectancies, perceived norms, alcohol use intensity, and alcohol‐related negative consequences.     

Longitudinal assessment of short‐term memory deterioration in a logopenic variant primary progressive aphasia with post‐mortem confirmed Alzheimer's Disease pathology

In the field of dementia research, there are reports of neurodegenerative cases with a focal loss of language, termed primary progressive aphasia (PPA). Currently, this condition has been further sub‐classified, with the most recent sub‐type dubbed logopenic variant (PPA‐LV). As yet, there remains somewhat limited evaluation of the characteristics of this condition, with no studies providing longitudinal assessment accompanied by post‐mortem examination. Moreover, a key characteristic of the PPA‐LV case is a deterioration of phonological short‐term memory, but again little work has scrutinized the nature of this impairment over time. The current study seeks to redress these oversights and presents detailed longitudinal examination of language and memory function in a case of PPA‐LV, with special focus on tests linked to components of phonological short‐term memory function. Our findings are then considered with reference to a contemporary model of the neuropsychology of phonological short‐term memory. Additionally, post‐mortem examinations indicated Alzheimer's disease type pathology, providing further evidence that the PPA‐LV presentation may reflect an atypical presentation of this condition.     

Chimpanzees demonstrate individual differences in social information use

Studies of transmission biases in social learning have greatly informed our understanding of how behaviour patterns may diffuse through animal populations, yet within-species inter-individual variation in social information use has received little attention and remains poorly understood. We have addressed this question by examining individual performances across multiple experiments with the same population of primates. We compiled a dataset spanning 16 social learning studies (26 experimental conditions) carried out at the same study site over a 12-year period, incorporating a total of 167 chimpanzees. We applied a binary scoring system to code each participant’s performance in each study according to whether they demonstrated evidence of using social information from conspecifics to solve the experimental task or not (Social Information Score—‘SIS’). Bayesian binomial mixed effects models were then used to estimate the extent to which individual differences influenced SIS, together with any effects of sex, rearing history, age, prior involvement in research and task type on SIS. An estimate of repeatability found that approximately half of the variance in SIS was accounted for by individual identity, indicating that individual differences play a critical role in the social learning behaviour of chimpanzees. According to the model that best fit the data, females were, depending on their rearing history, 15–24% more likely to use social information to solve experimental tasks than males. However, there was no strong evidence of an effect of age or research experience, and pedigree records indicated that SIS was not a strongly heritable trait. Our study offers a novel, transferable method for the study of individual differences in social learning.
