Using a sample of low‐income mothers enrolled in Early Head Start (n = 65), this study tested the hypothesis that parenting stress is affected by social support and self‐efficacy, in addition to family risk status and family income. Specifically, it was proposed that social support and self‐efficacy are psychological resources that are associated with lower parenting stress levels, and would moderate the impact of family income on parenting stress. A significant proportion of variance in parenting stress was explained by self‐efficacy, family risk, and the interaction of self‐efficacy and family income; family income alone was not a significant predictor of parenting stress levels. Mothers higher in self‐efficacy had lower levels of parenting stress, and income was less associated with parenting stress levels for mothers high in self‐efficacy. Social support was not associated with lower parenting stress levels, nor did social support moderate the effect of income on parenting stress. Family risk was also a strong and reliable predictor of parenting stress, suggesting that family circumstances are perhaps better predictors of parenting stress levels than income alone. These findings suggest that parenting stress among low‐income parents should be viewed as a function of psychological, as well as financial, resources. 相似文献

The purpose of this study was to investigate the impact of membership change on group creativity. Based on the literature suggesting stimulating effects of membership change in groups, we hypothesized that membership change would enhance the creativity of groups. Membership change involved randomly rotating a subset of group members among groups during a series of creative tasks. Using an idea generation paradigm, we compared the creativity of open groups (i.e., groups that experienced a change in their membership across tasks) with that of closed groups (i.e., groups whose membership was invariant across tasks) in two experiments. In both experiments, we found that open groups generated more ideas and more different kinds of ideas than did closed groups. Moreover, Experiment 2 revealed that it was the productivity of “newcomers” (measured in terms of their creative idea generation in a previous task) that exerted a positive impact on groups. We also found that the entry of more productive newcomers increased the creativity of “oldtimers” (i.e., people who remained in one group across tasks). Implications for the role of membership change in groups are discussed. 相似文献

The remarkable contributors to this special issue highlight the importance of developmental research on emotion and its regulation, as well as its conceptual and methodological challenges. This commentary offers some additional thoughts, especially concerning alternative views of the convergence of multiple measures of emotional responding, the conceptualization of emotion and emotion regulation, and future directions for work in this field. In the end, in light of the complex construction of emotion and its development, we may learn from studying the divergence among multiple components of emotional responding as we do from expectations of their convergence. In each case, some assembly is required. 相似文献

We taught manual signs to typically developing infants using a reversal design and caregiver-nominated stimuli. We delivered the stimuli on a time-based schedule during baseline. During the intervention, we used progressive prompting and reinforcement, described by Thompson et al. (2004, 2007), to establish mands. Following sign training, we conducted functional analyses and verified that the signs functioned as mands. These results provide preliminary validation for the verbal behavior functional analysis methodology and further evidence of the functional independence of verbal operants. 相似文献

The effects of a history of differential reinforcement for selecting a free-choice versus a restricted-choice stimulus arrangement on the subsequent responding of 7 undergraduates in a computer-based game of chance were examined using a concurrent-chains arrangement and a multiple-baseline-across-participants design. In the free-choice arrangement, participants selected three numbers, in any order, from an array of eight numbers presented on the computer screen. In the restricted-choice arrangement, participants selected the order of three numbers preselected from the array of eight by a computer program. In initial sessions, all participants demonstrated no consistent preference or preference for restricted choice. Differential reinforcement of free-choice selections resulted in increased preference for free choice immediately and in subsequent sessions in the absence of programmed differential outcomes. For 5 participants, changes in preference for choice were both robust and lasting, suggesting that a history of differential reinforcement for choice may affect preference for choice. 相似文献

Efforts to link media use to adolescents' sexual initiation have produced somewhat inconsistent results, perhaps as a result of the limited framing of the question. This study sought to expand current approaches by sampling college students instead of high school students, by investigating a range of sexual behaviors and media formats, and by testing a model that featured sexual cognitions as mediators. We tested our model with a sample of 796 heterosexual, male college students who reported on their regular consumption of 4 media (prime-time TV programs, music videos, movies, and men's magazines); their attitudes toward abstinence, the male sexual role, and nonrelational sex; their perceptions of peer sexual behavior; and several aspects of their sexual behavior (e.g., number of sexual partners). Findings revealed strong support for our mediated model, with exposure to men's magazines and movies contributing most strongly to their sexual cognitions, and with men's cognitions, in turn, contributing heavily to their sexual behavior. Some direct connections from media use to sexual behavior also emerged. Together, the findings provide insight into both potential mechanisms for and new approaches to addressing this issue. 相似文献

Students' endorsement of different characteristics associated with social success (sincere, responsible, dominant, disingenuous behaviors, appearance/athletic characteristics) were examined at six-month intervals for four time points spanning the transition from elementary to middle school (N = 558; 53% girls, 47% boys; 56% African American, 44% European American). Students' perceptions of socially successful children as sincere and responsible declined over time, whereas students' perceptions of socially successful children as dominant, disingenuous, and attractive/athletic increased over time. However, sincere behavior remained a top-rated characteristic at all time points and dominant and disingenuous behavior remained at the bottom, indicating that although the developmental trends were concerning the overall picture was not bleak. At all time points, girls endorsed sincere behavior as more important, and dominant and disingenuous behaviors and appearance/athletic characteristics as less important, to social success than boys. African American girls perceived appearance/athletic characteristic as less important to social success than other students. 相似文献

We describe a novel face distortion effect resulting from the fast-paced presentation of eye-aligned faces. When cycling through the faces on a computer screen, each face seems to become a caricature of itself and some faces appear highly deformed, even grotesque. The degree of distortion is greatest for faces that deviate from the others in the set on a particular dimension (eg if a person has a large forehead, it looks particularly large). This new method of image presentation, based on alignment and speed, could provide a useful tool for investigating contrastive distortion effects and face adaptation. 相似文献

We examined associations between children's sociometric status and (a) observed parental feedback as well as (b) child aggression. Participants were 94 children ages 6-10 (64 male; 44 with ADHD) and their parents. Children's peer status, parental feedback to their children, and child aggression were all assessed during lab-based playgroups of four children and their parents. Parent criticism in front of the child's peers was associated with the child receiving more negative ("disliked") and fewer positive ("liked") nominations, but only for children who displayed aggression; this interaction applied almost exclusively to children with ADHD. Parent praise in front of peers was associated with fewer negative nominations when children displayed low levels of aggression, but more at higher levels. Additional analyses revealed that relationships did not exist in the full sample between privately-given parental feedback and children's peer status. Processes by which peers use overheard adult feedback to inform their assessments of children are discussed. 相似文献
