Little is known about the magnitude and duration of mood responses to daily negative events as a function of gender, history of mood disorder, and current substance use. Using computerized ambulatory monitoring techniques, perceived negativity of minor daily events and state affect were prospectively examined every 3 h on average for a 7-day period. Event negativity was associated with depressed mood for 6–9 h following event occurrence, and was associated with happy mood for 3–6 h. Gender and substance use moderated the relationship between event negativity and mood states concurrently, and remained influential for approximately 3 h following the event. History of mood disorder did not moderate any within- or across-day relationships between event negativity and mood. No evidence was found for mood uplifts following daily events in either within- or across-day analyses. The findings are discussed relative to assessment timing in investigations of vulnerability-stress theories.  相似文献

The present study was designed to explore whether sustained attention tasks can be adequately described by a mindlessness perspective or a limited resource perspective. One hundred and seventy six participants (88 women and 88 men) were assigned at random to one of two signal salience conditions: high and low. Performance and self-reported states, Energetic Arousal, Tense Arousal, Task-Related-Thoughts, and Task-Unrelated-Thoughts, were collected. Overall performance efficiency and the rate of the vigilance decrement were influenced by the salience level of the signal being observed. Post-task self-reports of Task-Unrelated-Thoughts were significantly related to overall performance efficiency, but not with the vigilance decrement. Post-task self-reports of Energetic Arousal were significantly related to both overall performance and the vigilance decrement. The results support a resource theory perspective in regards to the vigilance decrement and are in contradiction to the mindlessness theory in regards to the vigilance decrement.  相似文献

In Experiment 1, a normal adult population drawn from a remote culture (Himba) in northern Namibia made similarity matches to [Navon, D. (1977). Forest before trees: The precedence of global features in visual perception. Cognitive Psychology, 9, 353-383] hierarchical figures. The Himba showed a local bias stronger than that has been previously observed in any other non-clinical human population. However, in Experiment 2, their recognition of normal or distorted ("Thatcherized") faces did not appear to have been affected by their attention to detail as has been suggested for autistic populations. The data are consistent with a cultural/experiential origin for population differences in local processing and suggest that attention to the local and global properties of stimuli may differ for hierarchical figures and faces.  相似文献

The purpose of this study was to use faultline theory to examine the effects of gender diversity on team creativity. Results from 80 teams working on an idea generation task indicated that the activation of gender faultlines negatively affected the number and overall creativity of ideas. However, gender faultlines that were not activated had no effect. Results also indicated that the relationship between activated gender faultlines and team creativity was partially mediated by the level of conflict within the team. Specifically, emotional conflict partially mediated the effects of activated gender faultlines on the number of ideas generated. Implications are discussed, as well as possible limitations and directions for future research.  相似文献

The present study examined the relationship between emotional intelligence and people's tendency to exhibit the ease of recall bias (emanating from the availability heuristic). Results showed that ability to understand emotions, a central element of emotional intelligence, was inversely related to the ease of recall bias, and that this relationship was mediated by participants' private self-focused attention. Implications for theory and practice, as well as limitations, are discussed.  相似文献

Valuation of goods often proceeds from a series of hypothetical pairwise choices. We examine reference dependence on the outcome of such evaluations in a large-scale study in which respondents make a series of choices between areas that differ on cost of living and the quality of lakes and rivers. We uncover three substantial reference effects. First, we find that respondents’ choices are altered by being told the national value of water quality. For these people, consistent with prospect theory, changes in water quality below the 65% referenced national standard are treated as losses and given more weight while identical changes above 65% are treated as gains and given less weight. Second, we find that the sequence of iterative choices matters in a surprising way. The iterations proceed by encouraging switching either by degrading the chosen alternative or improving the item chosen. We show that improving the item not chosen produces the greatest switching, a result consistent with prospect theory, but only if the item changed in the iteration becomes the reference alternative. Finally, we find a strong starting reference effect. That is, we show that the trade-off in the first choice reflected in the change in cost of living divided by the change in water quality has a substantial impact on the final valuation. We assess the relative impact of these three reference effects and suggest ways of dealing with them for valuation of non-market goods.  相似文献

The articles in this series describe complementary programs of research and innovative approaches to extend evidence-based interventions for youth with anxiety in several important directions: to extend the target age range [Pincus, D. B., Santucci, L. C., Ehrenreich, J. T., & Eyberg, S. M. (2008-this issue). Treating separation anxiety disorder in young children: Exploring the additive impact of exposure on PCIT treatment outcome. Cognitive and Behavioral Practice, 15]; to extend interventions to more broadly defined target populations, including youth with co-occurring psychiatric symptoms [Weersing, V. R., Gonzalez, A., Campo, J. V., & Lucas, A. N. (2008-this issue). Brief CBT for pediatric anxiety and depression: Piloting an integrated treatment approach. Cognitive and Behavioral Practice, 15] and somatic symptoms [Reigada, L. C., Fisher, P. H., Cutler, C., & Masia Warner, C. (2008-this issue). An innovative treatment approach for children with anxiety disorders and medically unexplained somatic complaints. Cognitive and Behavioral Practice, 15]; to extend access in specific community-practice settings [Ginsburg, G. S., Becker, K., Kingery, J., & Nichols, T. (2008-this issue). Transporting CBT for childhood anxiety disorders into inner city school-based mental health clinics. Cognitive and Behavioral Practice, 15; Reigada, L. C., Fisher, P. H., Cutler, C., & Masia Warner, C. (2008-this issue). An innovative treatment approach for children with anxiety disorders and medically unexplained somatic complaints. Cognitive and Behavioral Practice, 15; Weersing, V. R., Gonzalez, A., Campo, J. V., & Lucas, A. N. (2008-this issue). Brief CBT for pediatric anxiety and depression: Piloting an integrated treatment approach. Cognitive and Behavioral Practice, 15]; and to extend access to these evidence-based approaches, in general [Khanna, M. S., & Kendall, P. C. (2008-this issue). Computer assisted CBT for child anxiety: The Coping Cat CD. Cognitive and Behavioral Practice, 15]. This commentary addresses how, collectively, these programs of research illustrate promising approaches to intervention adaptation and testing. The discussion also explores potential directions that might facilitate future research, including potential directions for broadening the interventions research agenda to help ensure that high-quality, evidence-based interventions are ultimately available to children and adolescents with anxiety.  相似文献

Japanese ( N  = 48) and New Zealander ( N  = 55) participants were first assigned to one of two minimal groups, and then played a prisoner's dilemma game twice with an ingroup member and twice with an outgroup member. In one of the two games they played with an ingroup (or outgroup) member, participants and their partner knew one another's group memberships (mutual-knowledge condition). In the unilateral-knowledge condition, only the participants knew the group membership of their partner, but the partner did not know the group membership of the participant. Ingroup bias in cooperation emerged only in the mutual-knowledge condition in both countries; in the unilateral-knowledge condition no ingroup bias emerged. Mediational analyses found that, in accord with predictions, cooperation in the mutual-knowledge condition is mediated by expectation of the partner's cooperation. Ingroup bias in the mutual-knowledge condition emerged only among those who identified with the ingroup. Results provide support for a group heuristics account of ingroup favouritism in the minimal group. According to this account, participants who face minimal groups activate an ecologically adaptive heuristic of unilaterally cooperating with members of the same group, expecting indirect repayment from others in the same group.  相似文献

A consideration of how Kālī Pūjā enters festival contexts in early modern Bengal can suggest new ways of thinking about blood sacrifice in Hinduism. In this case, it appears that we may have underappreciated the impact of sectarian conflict. Through an exploration of the traditional origins of public Kālī Pūjā, I argue that its promotion with the attendant sacrifice by Brāhma?a aristocrats such as Rāja K???acandra Rāya of Nadīyā (1710–1782) can be read as a claim on public space for the Tantric yet socially and theologically conservative Smārta Hinduism favored by the upper castes over and against the comparatively egalitarian, sacrifice-averse ethos of the local Gau?īya Vai??ava movement.
