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. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

ABSTRACTThe 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. 相似文献

Drawing from theoretical and empirical literature linking shame to aggression and violence, the authors propose that shame may be an important variable to examine in studies of posttraumatic stress disorder (PTSD) and intimate partner violence (IPV) perpetration. The authors review the literature linking shame, PTSD, and IPV, propose ideas for future research, and suggest that shame and shame regulation may be a useful target of clinical interventions aimed at violence perpetrators. 相似文献
