Testing the Role of Aspirations,Future Expectations,and Strain on the Development of Problem Behaviors across Young and Middle Adulthood

Using prospective data collected across 14 years by the National Youth Survey Family Study (N = 1,436), we assessed change in aspirations, future expectations, and strain, as well as contemporaneous and longitudinal effects of these predictors on drug use, offending, and the perpetration of intimate partner violence. Growth curve models showed that, although time significantly predicted change in these variables, trajectories remained relatively stable. Contemporaneous random-intercept regression models revealed that all three measures were associated with all three problem behaviors. The effects were predictive longitudinally but some associations and gender differences were attenuated when controlling for prior involvement in outcomes.     

Countries with Greater Gender Equality Have More Positive Attitudes and Laws Concerning Lesbians and Gay Men

Social scientists have long discussed and empirically demonstrated how attitudes toward lesbians and gay men are determined in part by sexism and endorsement of gender roles, but only at the psychological level of analysis. We present data that considers these relationships at the cross-national level of analysis, using country-level measures of gender equality (the Gender Global Gap Index), aggregate measures of attitudes toward lesbians and gay men in a country, and a newly constructed measure of the progressiveness of sexual orientation laws. We show for the first time to our knowledge that countries that have the greatest gender equality also have (a) the most positive aggregate attitudes toward lesbians and gay men and (b) the strongest legislative protections for lesbians and gay men. These results hold even when controlling for plausible third variables such as a country’s level of religiosity and its economic and political development, each with their own separate effects. We discuss the results within the context of the various forces that contribute to, and work against, ensuring more accepting attitudes of, and equal rights for, lesbians and gay men. In conclusion, to fully understand support for lesbians and gay men and the laws that protect them, one should also consider how women are treated in a country.     

Working memory outcomes following traumatic brain injury in children: A systematic review with meta-analysis

The aim of this review is to systematically examine the literature concerning multicomponent working memory (WM)—comprising a central executive (CE), two storage components (phonological loop, PL and visuo-spatial sketchpad, VSSP), and episodic buffer (EB)—in pediatric traumatic brain injury (TBI). Electronic searches were conducted of MEDLINE, PsychINFO and EMBASE up to October 2014 with the inclusion criteria of children and adolescents with TBI, and quantitative methods to assess at least one component of WM. Meta-analytic procedures calculated pooled effect sizes for WM outcomes. Of the studies examined, 27 met the inclusion criteria. Children with TBI exhibited deficits in the CE and PL, but not in the VSSP, and no study could be found which examined the EB. Qualitative analysis found that greater TBI severity was associated with poorer CE functioning in five out of nine studies. Differences in patterns of brain activation were evident in four out of five fMRI studies that examined WM in TBI children and controls. Deficits in CE were associated with poorer mathematical skills in the only study that examined relations between WM and academic deficits. Notwithstanding the heterogeneity of the studies reviewed, TBI places children at risk of WM deficits. Moreover, this meta-analysis suggests that various components of WM have differential vulnerability to pediatric TBI, with significant deficits found in the CE and PL, but not in the VSSP (although the VSSP has rarely been examined to date). Future studies should be theoretically driven, employ tasks assessing all components of the WM model and examine the functional ramifications (including academic outcomes) of WM deficits in this population.     

Adolescents' emotion attributions and expectations of behavior in situations involving moral conflict

This study examined the idea that expectations of behavior in hypothetical situations involving potential moral transgressions are related to emotion attributions relating to both moral and cost-benefit considerations. We asked younger (14 years 5 months) and older (16 years 1 month) female and male adolescents (a) to make predictions about the probability that an adolescent placed in a hypothetical situation where a payoff could be obtained by acting in a nonmoral way would choose to do so and (b) to evaluate adolescents' attributions of moral (guilt) and cost-benefit-related emotions (satisfaction and fear) to the nonmoral action. Two different situations were examined; one looked at the possibility of stealing money from a lost wallet, and the other examined a situation where a contract with another peer could be broken for personal reasons. Results showed that expectations that the nonmoral action would be taken were positively related to the degree of satisfaction and negatively related to the degree of guilt and fear. However, the pattern of relations between emotion attributions and behavioral expectations differed between the two situations. Female and male adolescents had different levels of emotion attributions and behavioral expectations, but the relation between the two was similar for both. Finally, developmental comparisons indicated that older adolescents put more weight on guilt and were more internally consistent in the way that emotions were integrated into behavioral expectations.     

The role of white matter hyperintensities and medial temporal lobe atrophy in age-related executive dysfunctioning

Various studies support an association between white matter hyperintensities (WMH) and deficits in executive function in nondemented ageing. Studies examining executive functions and WMH have generally adopted executive function as a phrase including various functions such as flexibility, inhibition, and working memory. However, these functions include distinctive cognitive processes and not all may be affected as a result of WMH. Furthermore, atrophy of the medial temporal lobe (MTA) is frequently observed in ageing. Nevertheless, in previous studies of nondemented ageing MTA was not considered when examining a relationship between white matter and executive function. The goal of the present study was to examine how WMH and MTA relate to a variety of executive functions, including flexibility, fluency, inhibition, planning, set shifting, and working memory. Strong correlations were observed between WMH and MTA and most of the executive functions. However, only MTA was related to flexibility and set shifting performance. Regression analysis furthermore showed that MTA was the strongest predictor of working memory, after which no further significant association with WMH was noted. Alternatively, both MTA and periventricular hyperintensities independently predicted inhibition performance. These findings emphasize the importance of MTA when examining age-related decline in executive functioning.     

Correcting a metacognitive error: feedback increases retention of low-confidence correct responses

Previous studies investigating posttest feedback have generally conceptualized feedback as a method for correcting erroneous responses, giving virtually no consideration to how feedback might promote learning of correct responses. Here, the authors show that when correct responses are made with low confidence, feedback serves to correct this initial metacognitive error, enhancing retention of low-confidence correct responses. In 2 experiments, subjects took an initial multiple-choice test on general knowledge facts and made a confidence judgment after each response. Feedback was provided for half of the questions, and retention was assessed by a final cued-recall test. Taking the initial test improved retention relative to not testing, and feedback further enhanced performance. Consistent with prior research, feedback improved retention by allowing subjects to correct initially erroneous responses. Of more importance, feedback also doubled the retention of correct low-confidence responses, relative to providing no feedback. The function of feedback is to correct both memory errors and metacognitive errors.     

Children's false memories: easier to elicit for a negative than for a neutral event

The present study examined the role of valence in the development of children's implanted false memories. Seventy-six 7-year-old children listened to two true and one false narrative. The false narrative was either neutral ("moving to another classroom") or emotional negative ("being accused by the teacher for copying off your neighbor"). In addition, half of the children were presented with their class photograph while listening to the narratives. During two interviews, children recalled as many details as possible from the true and false events. Results showed that the negative event elicited more false memories than the neutral event. The presentation of a true photograph did not promote the development of false memories.
