Ethnic identity and personal well-being of people of color: a meta-analysis

This article summarizes research examining the relationship between the constructs of ethnic identity and personal well-being among people of color in North America. Data from 184 studies analyzed with random effects models yielded an omnibus effect size of r = .17, suggesting a modest relationship between the 2 constructs. The relationship was somewhat stronger among adolescents and young adults than among adults over age 40. No differences were observed across participant race, gender, or socioeconomic status, which findings support the general relevance of ethnic identity across people of color. Studies correlating ethnic identity with self-esteem and positive well-being yielded average effect sizes twice as large as those from studies correlating ethnic identity with personal distress or mental health symptoms. Ethnic identity was thus more strongly related to positive well-being than to compromised well-being. Overall, the corpus of research reviewed consisted of correlational designs; limited scholarship has addressed causal mechanisms, mediating factors, or psychological functions of ethnic identity across different social contexts.     

Social skills in women with Turner Syndrome

The aim of this study was to evaluate the performance of a group of women with Turner Syndrome (TS) in interpersonal situations where several social skills were required, and to compare the results with unaffected sisters. Fifty-two TS females aged 15-35 years and 33 sisters aged 16-43 were evaluated using Del-Prette Social Skills Inventory (SSI) and individual interviews. Thirty mothers to subjects and sisters answered questionnaires. It was found that TS girls' performance in SSI was as good as their sisters' and even better in meeting new people and facing unknown situations (p = 0.020). Older TS women scored better than younger ones, differently from their sisters. There were no significant correlations between total score of TS women and their age at diagnosis, time of follow-up and height z-score. Mothers reported having more problems with TS girls than with sisters. Although TS girls demonstrated having social difficulties, just a few of them spontaneously complained about interpersonal problems in the interview. Results suggest that social difficulties may not cause TS girls major problems nor make them unhappy with their social lives, and/or TS girls may not be able to perceive their own difficulties. Good performance in SSI also suggests that TS girls can identify adequate skills in presented situations and answer in a way to obtain good scores, but they may not necessarily use their skills due to other factors like anxiety and shyness. They may also have a tendency to answer SSI in a way they consider socially desirable, masking their real difficulties.     

Working memory in the oldest-old: evidence from output serial position curves

In the present study, we examined adult age differences in short-term and working memory performance in middle-aged (45–64 years), young–old (65–74 years), old–old (75–89 years), and oldest–old adults (90 years and over) in the Louisiana Healthy Aging Study. Previous research suggests that measures of working memory are more sensitive to age effects than are simple tests of short-term memory Bopp and Verhaeghen (Journal of Gerontology: Psychological Sciences 60:223–233, 2005), Myerson, Emery, White, and Hale, (Aging, Neuropsychology, and Cognition 10:20–27, 2003). To test this hypothesis, we examined output serial position curves of recall data from three span tasks: forward and backward digit span and size judgment span. Participants’ recall patterns in the size judgment span task revealed that the two oldest groups of adults showed the largest decreases in recall performance across output serial positions, but did not differ significantly from each other. Correlation analyses indicated the strongest negative correlation with age occurred with the size judgment span task. Implications of these findings for understanding strategic processing abilities in late life are discussed.     

Longitudinal relations among maternal behaviors, effortful control and young children's committed compliance

In a sample (n = 235) of 30-, 42-, and 54-month-olds, the relations among parenting, effortful control (EC), impulsivity, and children's committed compliance were examined. Parenting was assessed with mothers' observed sensitivity and warmth; EC was measured by mothers' and caregivers' reports, as well as a behavioral task; impulsivity was assessed by mothers' and caregivers' reports; and committed compliance was observed during a cleanup and prohibition task, as well as measured by adults' reports. Using path modeling, there was evidence that 30-month parenting predicted high EC and low impulsivity a year later when the stability of the outcomes was controlled, and there was evidence that 30- and 42-month EC, but not impulsivity, predicted higher committed compliance a year later, controlling for earlier levels of the outcomes. Moreover, 42-month EC predicted low impulsivity a year later. Fixed effects models, which are not biased by omitted time-invariant variables, also were conducted and showed that 30-month parenting still predicted EC a year later, and 42-month EC predicted later low impulsivity. Findings are discussed in terms of the importance of differentiating between effortful control and impulsivity and the potential mediating role of EC in the relations between parenting and children's committed compliance.     

Dynamic visual noise reduces confidence in short-term memory for visual information

Previous research has shown effects of the visual interference technique, dynamic visual noise (DVN), on visual imagery, but not on visual short-term memory, unless retention of precise visual detail is required. This study tested the prediction that DVN does also affect retention of gross visual information, specifically by reducing confidence. Participants performed a matrix pattern memory task with three retention interval interference conditions (DVN, static visual noise and no interference control) that varied from trial to trial. At recall, participants indicated whether or not they were sure of their responses. As in previous research, DVN did not impair recall accuracy or latency on the task, but it did reduce recall confidence relative to static visual noise and no interference. We conclude that DVN does distort visual representations in short-term memory, but standard coarse-grained recall measures are insensitive to these distortions.     

Common patterns of prediction of literacy development in different alphabetic orthographies

Previous studies have shown that phoneme awareness, letter-sound knowledge, rapid automatized naming (RAN), and verbal memory span are reliable correlates of learning to read in English. However, the extent to which these different predictors have the same relative importance in different languages remains uncertain. In this article, we present the results from a 10-month longitudinal study that began just before or soon after the start of formal literacy instruction in four languages (English, Spanish, Slovak, and Czech). Longitudinal path analyses showed that phoneme awareness, letter-sound knowledge, and RAN (but not verbal memory span) measured at the onset of literacy instruction were reliable predictors, with similar relative importance, of later reading and spelling skills across the four languages. These data support the suggestion that in all alphabetic orthographies, phoneme awareness, letter-sound knowledge, and RAN may tap cognitive processes that are important for learning to read.     

D1/D5 dopamine receptors modulate spatial memory formation

We investigated the effect of the intra-CA1 administration of the D1/D5 receptor antagonist SCH23390 and the D1/D5 receptor agonist SKF38393 on spatial memory in the water maze. When given immediately, but not 3h after training, SCH23390 hindered long-term spatial memory formation without affecting non-spatial memory or the normal functionality of the hippocampus. On the contrary, post-training infusion of SKF38393 enhanced retention and facilitated the spontaneous recovery of the original spatial preference after reversal learning. Our findings demonstrate that hippocampal D1/D5 receptors play an essential role in spatial memory processing.     

Social and moral norm differences among Portuguese 1st and 6th year medical students towards their intention to comply with hand hygiene

This study examines social and moral norms towards the intention to comply with hand hygiene among Portuguese medical students from 1st and 6th years (N = 175; 121 from the 1st year, 54 from the 6th year). The study extended the theory of planned behaviour theoretical principles and hypothesised that both subjective and moral norms will be the best predictors of 1st and 6th year medical students' intention to comply with hand hygiene; however, these predictors ability to explain intention variance will change according to medical students' school year. Results indicated that the subjective norm, whose referent focuses on professors, is a relevant predictor of 1st year medical students' intention, while the subjective norm that emphasises the relevance of colleagues predicts the intentions of medical students from the 6th year. In terms of the moral norm, 6th year students' intention is better predicted by a norm that interferes with compliance; whereas intentions from 1st year students are better predicted by a norm that favours compliance. Implications of the findings highlight the importance of role models and mentors as key factors in teaching hand hygiene in medical undergraduate curricula.     

Virtual Reality as a Selfobject Function: Towards Reclaiming Unlived Potentialities

ABSTRACT

In this article, I illustrate how virtual reality may promote reclaiming unlived potentialities, unconscious or disavowed. Using Kohut’s concept of the Virtual Self, I suggest that virtual aspects of the self, its potential capability, are unconscious (or unknown) until met by someone or something that promotes their transformation into a conscious state of mind and supports their realization. In this sense, the virtual experiences of the self are drawn from the preconscious. Three vignettes demonstrate the transformative potential of virtual experiences when they are perceived as recognizing, and responsive to, the Self’s needs. Two vignettes are drawn from ancient myths and illuminate how the virtual zone has inspired transformation and expansion of self awareness already in ancient times. A third vignette is presented to illustrate how, at the advent of social media, disavowed and dissociated needs are channeled into cyberspace as communications that are unconsciously geared to reclaim unlived potentialities. Cyber reality converses with conventional reality and, thus, is appreciated as a mode of psychic advance toward a new kind of self consciousness.
