社交媒体使用与错失焦虑均是当下生活中较为常见的现象, 诸多研究探讨了两者间的内在联系, 但研究结果却存在很大差异。为明确两者之间的整体关系, 以及产生分歧的原因, 对检索后获得的65项研究(70个独立样本)使用随机效应模型进行了元分析。结果发现:社交媒体使用与错失焦虑存在显著正相关(r = 0.38, 95% CI [0.34, 0.41]); 二者的相关强度受社交媒体使用测量指标和社交媒体类型的调节, 但不受性别、年龄、错失焦虑测量工具和个体主义指数的调节。结果一定程度上澄清了大众传播的社会认知理论和数字恰到好处假说的争论, 表明社交媒体使用程度越高的人往往也会伴随着较高水平的错失焦虑。防止社交媒体过度使用, 尤其是引导大众合理使用以图像为中心并且开放度较高的社交媒体有助于错失焦虑的缓解。 相似文献

网络信息的纷繁复杂,让人们担忧因错失信息而导致自身的利益受损,本研究探讨这种现象的加剧对个体的亲社会行为的影响。本研究分别使用问卷法(研究1)和实验法(研究2),探究错失恐惧对亲社会行为的影响以及在其过程中人际安全感的中介作用和基本心理需要满足的调节作用。结果发现:(1)个体的错失恐惧程度负向预测了其亲社会行为;(2)人际安全感在错失恐惧对亲社会行为的影响中起中介作用,高的错失恐惧水平会降低个体的人际安全感,从而减少个体的亲社会行为;(3)基本心理需要满足在错失恐惧对亲社会行为的负向预测作用中起调节作用,当个体的基本心理需要满足程度低的时候,错失恐惧对亲社会行为的消极影响显著增强。 相似文献

即刻消退缺损(immediate extinction deficit, IED)是指在条件性恐惧习得后, 立即进行的消退训练不能长期抑制恐惧记忆的现象。IED可能与消退起始时的应激水平和事件分割等因素有关。在高应激水平下, 消退记忆的巩固受损导致IED; 而在中等或较低的应激水平条件下, 即刻消退有效但效果可能容易受事件分割的影响。IED的神经生物学机制涉及应激激活蓝斑去甲肾上腺素能系统, 去甲肾上腺素引起杏仁核基底外侧核(basolateral amygdala, BLA)过度兴奋, 然后BLA通过投射突触抑制在恐惧消退中起核心作用的内侧前额叶神经元的活动。未来研究应注意即刻消退缺损引起的长期后果, 并深入探讨如何优化即刻消退在临床上的应用。 相似文献

The effect of fear on two types of aggression in rats was investigated by adding a cat stimulus to a colony in which the dominant male was attacking an intruder (offensive aggression), or, to a tube test situation in which defensive biting was measured before and during tail shock. The cat completely abolished offense in the colony; when the cat was presented and removed before a strange rat was placed in the colony, attack on the intruder was also reduced. In contrast, defensive biting was unchanged or even slightly potentiated by the presence of the cat, demonstrating a separation of the effects of fear on offensive and defensive aggression. 相似文献

Five male/two female rat colonies were established in visible burrow systems, with males selected for pregrouping attack scores and also evaluated in open field and cat odor tests. Dominant-subordinate pregrouping attack differences suggested that the males becoming dominant are those showing more persistent and higher level attack. For six colonies showing dominant-subordinate behavioral differences, pregrouping defense tests failed to predict subordinate status. However, pregrouping defense scores were reliably correlated with subordinate pre-postgrouping change scores for voluntary ethanol consumption. Subordinates showed higher ranked ethanol consumption than dominants, but these groups were not different on pregrouping ethanol consumption. Subordinate postgrouping ethanol consumption was positively correlated with pregrouping attack toward an adult intruder, consonant with previous findings that highly aggressive subordinates are the targets of more intense attack by dominants. These results provide further support for a view that subordination stress increases voluntary ethanol consumption in male rats and suggest some additional individual differences factors that may be involved in increased ethanol consumption for male subordinates. © 1992 Wiley-Liss, Inc. 相似文献

A questionnaire study involving white collar workers (n=48) investigated the effects of the threat of retaliation, seriousness of malpractice and occupational status of the observer on the likelihood and method of whistle-blowing chosen. In line with previous whistle-blowing and bystander intervention research, the likelihood of whistle-blowing was greater for serious malpractices and where threatened retaliation was low. The effect of retaliation was only significant for serious white collar malpractices and in every situation internal whistle-blowing was more likely than external. The general likelihood of whistle-blowing was positively correlated with the perception that reporting the malpractice would result in change. 相似文献

Selective breeding of wild rats over many generations on the basis of low or high defensive threat and attack to human approach and contact has produced highly polarized “domesticated” and “wild-type” animals. Because the selection procedure selectively involves these two defense patterns, and these clearly differ in the two groups, it is of interest to determine if other, nonselected, defensive behaviors to threat stimuli also change. “Domesticated” and “wild-type” rats of the thirty-fifth generation were run in a fear defense test battery (F/DTB) to systematically evaluate defensive behaviors to a variety of present threat stimuli. “Domesticated” rats showed reduced avoidance and slower flight speed to an approaching experimenter, reduced jump/startle response to handelap and dorsal contact, less vocalization and boxing to vibrissae stimulation or to an anesthetized conspecific, and reduced defensiveness to an attempted pickup by the experimenter. These results indicate that selective bi-directional breeding for defensive threat and attack to human approach and contact produces group differences in a variety of defensive behaviors, and in defensiveness to stimuli other than those on which the selection was based. © 1994 Wiley-Liss, Inc. 相似文献

Curiosity as a clinical entity has been a neglected subject in the psychoanalytic literature. Freud never addressed the issue of curiosity systematically. His interest was in trying to account for children's sexual questioning. Nevertheless, hinderance to internal curiosity—this is to say, that which intimidates and abates the appetite for an exploration of one's motives—is part and parcel of psychoanalytic inquiry. And, arguably, there is no greater clinical challenge for the analyst than trying to treat an analysand who appears to lack an interest in the underlying causes of his unhappiness. The problem of impeded self-inquiry is usually exacerbated in people with more serious emotional disturbances. My position here is that in studying the conditions that mitigate against curiosity in a seriously disturbed patient, we gain access to an enlarged version of the curiosity problems of our less disturbed patients. Here I interpret my clinical impressions about problems with curiosity with ideas from the writings of Martin Buber and Albert Camus. 相似文献
