Negative emotions are linked with a local, rather than global, visual processing style, which may preferentially facilitate feature-based, relative to holistic, processing mechanisms. Because faces are typically processed holistically, and because social contexts are prime elicitors of emotions, we examined whether negative emotions decrease holistic processing of faces. We induced positive, negative, or neutral emotions via film clips and measured holistic processing before and after the induction: participants made judgements about cued parts of chimeric faces, and holistic processing was indexed by the interference caused by task-irrelevant face parts. Emotional state significantly modulated face-processing style, with the negative emotion induction leading to decreased holistic processing. Furthermore, self-reported change in emotional state correlated with changes in holistic processing. These results contrast with general assumptions that holistic processing of faces is automatic and immune to outside influences, and they illustrate emotion's power to modulate socially relevant aspects of visual perception.  相似文献

Carrying objects requires coordination of manual action and locomotion. This study investigated spontaneous carrying in 24 walkers who were 13 months old and 26 crawlers who were 13 months old during 1-hr, naturalistic observations in the infants' homes. Carrying was more common in walkers, but crawlers also carried objects. Typically, walkers carried objects in their hands, whereas crawlers multitasked by using their hands simultaneously for holding objects and supporting their bodies. Locomotor experience predicted frequency of carrying in both groups, suggesting that experienced crawlers and walkers perceive their increased abilities to handle objects while in motion. Despite additional biomechanical constraints imposed by holding an object, carrying may actually improve upright balance: Crawlers rarely fell while carrying an object, and walkers were more likely to fall without an object in hand than while carrying. Thus, without incurring an additional risk of falling, spontaneous carrying may provide infants with new avenues for combining locomotor and manual skills and for interacting with their environments.  相似文献

Numerous cross-sectional studies confirm the long-theorized association between mothers’ depression and lower parenting self-efficacy (PSE) beliefs. However, cross-sectional studies leave unanswered the direction of this association: Does depression predict PSE? Does PSE predict depression? Are both true? Does the strength of the association between depression and PSE, regardless of the direction, generalize across participant characteristics and study design features? How stable is PSE over time? And how effective are interventions at enhancing PSE? To answer these questions, we conducted a meta-analytic review of longitudinal studies. With 35 eligible studies (22,698 participants), we found support for both models: there was a significant pooled effect of both depression on PSE and of PSE on depression, with nearly identical effect sizes (d?=?????0.21 and ??0.22, respectively). The association was stronger in samples with mothers’ younger average age and studies that measured PSE among mothers relative to during pregnancy. We found a medium degree of stability in the index of PSE, d?=?0.60. Finally, the estimated pooled effect size between being in an intervention group versus control group and PSE was 0.505. Overall, we found support for (1) bidirectional associations between depression and PSE in mothers, (2) the stability of PSE over time, and (3) the strength of the relationship between PSE and depression with intervention. These results suggest the importance of continuing to develop, test, and disseminate interventions to enhance PSE. We interpret these findings in the context of both depression and low PSE having serious consequences for child outcomes and maladaptive parenting.

This study examines the vocational concerns of 185 elementary teachers. Participants were classified based on their perceptions of the magnitude of their classroom demands and resources. These groupings were then examined for differences in teachers' personal coping resources, job satisfaction, and occupational commitment. Results indicated that teachers classified as perceiving high classroom demand vis‐à‐vis classroom resources reported lower personal coping resources, less job satisfaction, and more plans to leave their current job.  相似文献

Heidegger’s two modes of thinking, calculative and meditative, were used as the thematic basis for this qualitative study of physicians from seven countries (Canada, China, India, Ireland, Japan, Korea, & Thailand). Focus groups were conducted in each country with 69 physicians who cared for the elderly. Results suggest that physicians perceived ethical issues primarily through the lens of calculative thinking (76%) with emphasis on economic concerns. Meditative responses represented 24% of the statements and were mostly generated by Canadian physicians whose patients typically were not faced with economic barriers to treatment due to Canada’s universal health care system.  相似文献

Within the U.S. military, motor vehicle accidents (MVAs) are the leading cause of preventable morbidity and mortality. Prior combat exposure and anxiety symptoms are associated with risky and aggressive driving, which is responsible for over half of MVA fatalities. Therefore, interventions are needed to reduce driving anxiety and aggression in veterans in order to mitigate the public health impact of MVAs. Virtual reality exposure therapy (VRET) offers safe, controlled exposure to distressing stimuli. The current study piloted a novel virtual reality and cognitive behavioral intervention (VRET + CBT) for veterans that integrated both anxiety and anger management components. Virtual reality driving scenarios were delivered in a driving simulator and tailored for the military population. Six previously deployed veterans completed eight intervention sessions, as well as pre/post, one month follow-up and six to nine month follow-up assessments. Repeated measures ANOVAs demonstrated significant decline and large effect sizes for PTSD symptoms, driving phobia, hyperarousal in driving situations, anxiety/anger-related thoughts and behaviors, and risky driving. Hyperarousal in driving situations declined by 69%, aggressive driving declined by 29%, and risky driving declined by 21%. Treatment gains were maintained at follow-up. Recruitment, retention, immersion, simulator sickness scores, and qualitative feedback demonstrated feasibility of the intervention. Implications for future research and adaptation are discussed.  相似文献

Physical inactivity and limited time spent in nature are major societal concerns that affect the mental and emotional health of youth in the United States. As such, this study explored girls’ perspectives of barriers to outdoor physical activity using a qualitative participatory action research method called photovoice. Six themes emerged from data representing the girls’ perspectives of barriers to outdoor physical activity through photovoice: Very Busy Schedule, Social Media, Health Concerns, Indoor Activity Instead of Outdoor Activity, Electronic Devices, and Way of Life. Researchers address how counselors can use these findings to advocate on this issue, given that counselors are called to advocate at multiple levels to address barriers that inhibit the growth and development of clients.  相似文献

Young ethnic minority parents may lack psychological and financial resources to handle parenthood, increasing the risk of negative psychosocial and parenting outcomes. Partner support has been associated with positive coparenting, although findings have been mixed. Support from young parents’ own parents (“grandparents”) has been linked to adaptive family outcomes and may be particularly protective for African American and Latino parents whose cultures espouse interdependence. This study examined partner support and grandparent support as individual predictors of change in coparenting quality, and tested whether grandparent support moderated the relationship between partner support and change in coparenting quality over the first postpartum year. Participants were 136 African American and Latina adolescent mothers (age range?=?15–21 years) and their babies’ fathers (15–41 years). Partner and grandparent support were measured at 6 months postpartum. Coparenting quality was measured at 6 and 12 months postpartum, and change in coparenting quality was measured using latent change scores. Structural equation modeling was used to test the hypothesis that the relationship between partner support and change in coparenting quality would be moderated by grandparent support. Fit indices indicated a well-fitted model. Results demonstrated that the moderator term (partner support?×?grandparent support) significantly predicted change in coparenting quality. Specifically, partner support was positively associated with changes in coparenting quality when grandparent support was high; however, that association became weaker and changed direction for lower levels of grandparent support. Findings highlight the need to assess parents’ social support networks and grandparents’ impact on the coparenting quality of this at-risk population.  相似文献

The sex difference in jealousy is an effect that has generated significant controversy in the academic literature (resulting in two meta-analyses that reached different conclusions on the presence or absence of the effect). In this study, we had a team of researchers from different theoretical perspectives use identical protocols to test whether the sex difference in jealousy would occur across many different samples (while testing whether mate value would moderate the effect). In our samples, we found the sex difference in jealousy to occur using both forced choice and continuous measures, this effect appeared in several different settings, and, we found that mate value moderated participant responses. The results are discussed in light of the controversy surrounding the presence of the effect.  相似文献
