Whereas many previous studies suggest that self-esteem may buffer against the psychological threat of death, recent research has begun to suggest that self-control also may serve as a buffer. Two studies examined the possibility that dispositional self-control uniquely predicts responses to mortality salience, above and beyond self-esteem. In Study 1, an initial exercise in emotion regulation increased subsequent accessibility of death thoughts. In Study 2, mortality salience increased worldview defense. Both of these effects were moderated by dispositional self-control, such that the effects occurred among participants with low but not high self-control. More importantly, these moderating effects were observed over and above the moderating effects of self-esteem. Findings suggest that self-control may serve as an important and unique buffer against thoughts of death. 相似文献

探讨如何提高急性白血病患者染色体/特异融合基因异常的检出率与准确率。联合常规细胞遗传学技术、多重巢式聚合酶链反应技术对120例急性白血病患者进行检测。结果表明:应用常规细胞遗传学检测出82例核型异常,占68.3%,而应用多重巢式聚合酶链反应技术检测出54例融合基因异常,占45%。联合这两种技术,120例急性白血病患者的遗传学异常检出率为:75%(90/120),其中有65例明确了具体染色体改变或特异性融合基因异常。30例患者经常规细胞遗传学检测出具有t(8;21)(q22;q22)或t(15;17)(q22;q12),多重巢式聚合酶链反应技术检测出39例患者具有AML1/ETO、PML/RARA或CBFB/MYH11融合基因异常。当存在染色体数目异常,或者不存在19种融合基因之一时多重巢式聚合酶链反应结果为阴性。提示常规细胞遗传学技术联合多重巢式聚合酶链反应技术可以有效地提高急性白血病患者染色体异常/特异性融合基因的检出率。 相似文献

Older persons are among the major marginalized, disenfranchised citizens worldwide, yet this group has generally been ignored in the community psychology literature. In this paper, we trace the demographic trends in aging worldwide, and draw the field’s attention to the United Nations Program on Aging, which structures its policy recommendations in terms of concepts that are familiar to community psychologists. A central theme of the paper is that community psychology can have a role in producing the conceptual shifts needed to change societal attitudes now dominated by negative age stereotypes. 相似文献

Aggressive responding following benzodiazepine ingestion has been recorded in both experimental and client populations, however, the mechanism responsible for this outcome is unclear. The goal of this study was to identify an affective concomitant linked to diazepam‐induced aggression that might be responsible for this relationship. Thirty males (15 diazepam and 15 placebo) participated in the Taylor Aggression Paradigm while covertly being videotaped. The videotapes were analyzed using the Facial Action Coding System with the goal of identifying facial expression differences between the two groups. Relative to placebo participants, diazepam participants selected significantly higher shock settings for their opponents, consistent with past findings using this paradigm. Diazepam participants also engaged in significantly fewer appeasement expressions (associated with the self‐conscious emotions) during the task, although there were no group differences for other emotion expressions or for movements in general.

体验活动对冲动性购买行为的影响:情感反应视角 总被引:1,自引:0,他引:1
冲动性购买在商场和超市的零售中占有相当的比例,本研究以旅游者和旅游购物为实证研究对象,在323份调查问卷的基础上,采用方差分析和回归分析的方法探讨了体验活动对冲动性购买行为的影响及其情感反应机制。结果表明:在激发消费者冲动性购买行为方面,顾客参与的效果最好,其次是顾客学习,再次是顾客娱乐;顾客参与会导致更多的快乐的情感反应,而快乐的情感反应对冲动性购买意愿的影响最为显著;顾客学习会导致更多的支配的情感反应,而支配的情感反应对冲动性购买意愿的影响较为显著。 相似文献

The aim of the present experiments was to clarify sex differences in socio-developmental factors that affected defense behavior in rats. Sex differences in the defensive burying behavior of rats, and related social factors, were explored in three developmental stages: juvenile, puberty, and adult; 30, 50, and 80 days of age, respectively. The duration of burying, digging into bedding material, stretch-attend postures, and crouch/freezing were measured in a shock-prod test. For males, the duration of burying was longer in the juvenile and pubertal stages than in adulthood. For females, no age differences in the duration of burying were found. Males showed longer burying durations than females in both the juvenile and pubertal stages. For both sexes, the highest duration of digging was found in the juvenile stage, and females showed longer durations of digging than males. Both male and female rats isolated during the juvenile stage, from 26 to 40 days of age, showed smaller durations of burying behavior compared to pair-reared rats. This effect of juvenile isolation was maintained among both adult males and females even when they were returned to pair rearing after isolation. Isolation during adulthood, from 66 to 80 days of age, increased burying behavior in males, but decreased it in females. The durations of digging, stretch-attend postures, and crouch/freezing were not affected by isolation. The decrease in defensive burying and its increase resulting from isolation in adult male rats, suggest that the emergence of adult-like social relationships in males suppressed the duration of burying. Male and female rats isolated during the juvenile stage maintained lower levels of burying, suggesting that social experience as juveniles is important for the emergence of defensive burying behavior. 相似文献

Complex information, such as that required for motor skills, can be learned implicitly, without awareness. Much debate has centered on the appropriate methods for proving that implicit learning is not influenced by explicit awareness. A recent study by Destrebecqz and Cleeremans has provided compelling evidence for implicit sequence learning without awareness by using the ‘method of opposition’. 相似文献
