Understanding the Association Between Spirituality,Religiosity, and Feelings of Happiness and Sadness Among HIV-Positive Indian Adults: Examining Stress-Related Growth as a Mediator

This study examined the role of stress-related growth as a mediator of the associations between spirituality, religiosity, and feelings of happiness and sadness in a sample of 178 HIV-positive Indian adults. Results indicated that spirituality, but not religiosity, was associated with feelings of happiness and sadness. Subsequent mediation analyses indicated that stress-related growth fully mediated the relationships involving spirituality and feelings of happiness and sadness. Overall, our findings point to the importance of facilitating greater spiritual development among HIV-positive Indians, as well as promoting strategies that help them develop and apply stress-related growth coping methods in their lives.     

Leaving to Love: Filipina Caregivers and The Queer Kinship of Transnational Childcare

This article considers the affective and psychosocial dimensions of transnational childcare. It offers a transdisciplinary engagement with the subjectivity of Filipina caregivers, suggesting that the ways in which their love and care are split across borders and nations “queers” conceptions of family, childhood, and maternal obligation. Specifically, queer theories of kinship and diaspora are employed to offer an affective reading of Canada’s Caregiver Program. D. W. Winnicott’s theory of the “good enough” mother is also engaged in an effort to complicate narratives of maternal obligation, neglect, and love.     

Bidirectional Associations between Peer Victimization and Functions of Aggression in Middle Childhood: Further Evaluation across Informants and Academic Years

The current 3-wave study examined bidirectional associations between peer victimization and functions of aggression across informants over a 1-year period in middle childhood, with attention to potential gender differences. Participants included 198 children (51% girls) in the third and fourth grades and their homeroom teachers. Peer victimization was assessed using both child- and teacher-reports, and teachers provided ratings of reactive and proactive aggression. Cross-classified multilevel cross-lagged models indicated that child-reports, but not teacher-reports, of peer victimization predicted higher levels of reactive aggression within and across academic years. Further, reactive aggression predicted subsequent increases in child- and teacher-reports of peer victimization across each wave of data. Several gender differences, particularly in the crossed paths between proactive aggression and peer victimization, also emerged. Whereas peer victimization was found to partially account for the stability of reactive aggression over time, reactive aggression did not account for the stability of peer victimization. Taken together with previous research, the current findings suggest that child-reports of peer victimization may help identify youth who are risk for exhibiting increased reactive aggression over time. Further, they highlight the need to target reactively aggressive behavior for the prevention of peer victimization in middle childhood.     

COMT genotype influences prefrontal response to emotional distraction

Early studies of genetic effects on brain activity have been conducted to investigate primarily either the influence of polymorphisms in dopaminergic genes, especially the catechol-O-methyltransferase (COMT) gene, on prefrontal cognitive processes such as working memory, or that of polymorphisms in the serotonin transporter gene on the amygdala response to threatening stimuli. Here, we address genetic influences on the neural systems underlying cognitive-affective interactions. Specifically, we assess the effect of the COMT val¹⁵⁸met polymorphism on frontal regulation of attention under emotional distraction. Healthy volunteers were scanned while performing a house-matching task with affectively negative versus neutral distractors. Effects of val allele load were examined on frontal regions associated with attentional control and emotion regulation, and on parahippocampal regions associated with perception of houses. As we predicted, val load correlated positively with activity in control- and task-related regions during performance under emotional distraction. These findings provide an initial step toward identifying genetic contributions to interindividual variability in recruitment of mechanisms that regulate affective processing.     

A bird in hand: discouraging gambling on a slot machine simulation

Using a slot machine simulation, our laboratory has found that participants, given the opportunity not to gamble and to keep the money they have been staked, almost always choose to play the simulation. In this study, the authors investigated whether increasing the salience of the money for which participants played or increasing the response effort required to gamble the money would decrease gambling. In Experiment 1, participants in different groups were told about, were shown, or held the dollars 10 they were to be staked to play the simulation. Results showed that participants who held the money prior to gambling played fewer trials and bet less money than participants in other groups. In Experiment 2, participants in different groups were staked with dollars 5 in nickels, quarters, or their choice of nickels or quarters. Results showed that the participants staked with nickels ultimately gambled a similar amount of money as did participants staked with quarters. They did so by playing the simulation more times than the other participants. Participants staked with nickels did, however, end the session with the most money. Findings suggest ways that gambling and gambling losses can be lessened.     

Aerobic Exercise and Creative Potential: Immediate and Residual Effects

The potential effects of aerobic exercise on creative potential were explored both immediately following moderate aerobic exercise and after a 2-hr lag. Sixty college students participated in an experiment consisting of 3 regimens varying the time when a Torrance Test of Creative Thinking was taken in relation to exercise completion. The results supported the hypotheses that creative potential will be greater on completion of moderate aerobic exercise than when not preceded by exercise (immediate effects), that creative potential will be greater following a 2-hr lag time following exercise than when not preceded by exercise (residual effects), and that creative potential will not be significantly different immediately following exercise than after a 2-hr lag time following exercise (enduring residual effects). Limitations and implications for future research were discussed.     

Neuropsychological Functioning in Children with Posttraumatic Stress Disorder

Posttraumatic stress disorder (PTSD) has been associated with deficits in the areas of verbal memory and learning, executive functioning, working memory, and attention in adults. Findings have been less consistent in the few studies examining neuropsychological functioning in childhood PTSD, which are often limited by comparing children with PTSD to children without trauma histories, making it unclear whether observed neuropsychological deficits are related to trauma exposure or to PTSD symptomatology. In an ethnically diverse sample of 62 children who witnessed intimate partner violence (n = 27 PTSD+ and 35 PTSD?), children with PTSD exhibited slower and less effective learning, heightened sensitivity to interference, and impaired effect of rehearsal on memory acquisition on the California Verbal Learning Test – Children's Version, a word list learning task. Both groups performed in the below average range on measures of executive functioning, attention, and intellectual ability.     

Longitudinal Analysis of Associations between 3-D Mental Rotation and Mathematics Reasoning Skills during Middle School: Across and within Genders

ABSTRACT

The development of math reasoning and 3-d mental rotation skills are intertwined. However, it is currently not understood how these cognitive processes develop and interact longitudinally at the within-person level – either within or across genders. In this study, 553 students (52% girls) were assessed from fifth to seventh grades on 3-d mental rotation spatial skills (assessed each fall) and numerical and algebraic math reasoning skills (assessed each spring). Boys outperformed girls on mental rotation tests across all three grades, and on fifth and seventh grade math reasoning tests. Consistent with the literature on between-person comparisons, there was a positive correlation between mental rotation and math reasoning skills in the full sample and for both genders. A random intercept cross-lagged panel model was used to control for these confounding group-level differences in order to isolate within-person associations between earlier and later performance. Initially in fifth grade, math reasoning predicted subsequent sixth grade mental rotation skills. By seventh grade, more advanced mental rotation skills were associated with subsequent math reasoning skills while math reasoning skills were no longer predictive of mental rotation skills. An examination of gender differences revealed that this pattern was driven by boys while girls experienced less within-person change. These findings suggest that boys may initially rely in part on their math reasoning skills to solve 3-d mental rotation tasks. However, as their 3-d mental rotation skills mature, they begin to primarily depend upon these developing spatial skills to solve math reasoning problems rather than the reverse.
