Safety Behavior After Extinction Triggers a Return of Threat Expectancy

Safety behavior is involved in the maintenance of anxiety disorders, presumably because it prevents the violation of negative expectancies. Recent research showed that safety behavior is resistant to fear extinction. This fear conditioning study investigated whether safety behavior after fear extinction triggers a return of fear in healthy participants. Participants learned that two stimuli (A and C) were followed by an aversive loud noise (“threat”), and one stimulus (B) was not. Participants then learned to use safety behavior that prevented the loud noise. Next, A and C were no longer followed by the loud noise, which typically led to extinction of threat expectancy. Safety behavior then became available again for C, but not for A and B. All participants used safety behavior on these C trials. In a final test phase, A, B, and C were presented once without the availability to use safety behavior. At each stimulus presentation, participants rated threat expectancy by indicating to what extent they expected that the loud noise would follow. Compared with the last extinction trial, threat expectancy increased for C in the test phase, whereas it did not increase for A and B. Hence, safety behavior after the extinction of classically conditioned fear caused a partial return of fear. The findings suggest that safety behavior may be involved in relapse after exposure-based therapy for anxiety disorders.     

Anxiety and Threat Perception Abnormalities in Normal Children

The current study examined the relationship between childhood anxiety and threat perception abnormalities. Children (N = 105) were exposed to stories reflecting three types of anxiety: social anxiety, separation anxiety, and generalized anxiety. From children's reactions to the stories, a number of threat perception indices were derived. Children's level of anxiety was assessed by means of questionnaires and a structured diagnostic interview. Results indicated that high levels of anxiety, as measured by questionnaires and interview, were accompanied by a high frequency of threat perception, high ratings of threat, a high frequency of threatening interpretations, high levels of negative feelings and cognitions, and an early detection of threat. Furthermore, results seemed to suggest that threat perception abnormalities were mediated by children's general level of anxiety rather than by levels of specific anxiety symptoms.     

Schadenfreude and just world belief

The present study tested the hypothesis that a threat of a just world belief intensifies experience of schadenfreude (i.e., pleasure at another's misfortune). The participants read scenarios which were designed to threaten or maintain their just world belief. Subsequently, they were transferred to an online magazine presenting funny stories about other peoples' failures. As presumed, the participants exposed to the threat of just world belief spent more time on reading. These results confirmed the existence of a link between just world threat and schadenfreude.     

个体的政治倾向及其变化机制

政治倾向是个体在意识形态上的定位, 可以分为自由主义和保守主义, 政治倾向使个体在认知和行为等方面存在显著差异。虽然个体的政治倾向相对稳定, 但也会受威胁的影响而变化。动机性社会认知理论认为威胁使所有人都变得更加保守, 恐惧管理理论认为威胁使个体更坚信自己原有的文化世界观, 使原有政治倾向更加明显。本文在深入分析讨论的基础上, 指出两种理论分歧的原因在于忽略了外部威胁与内部威胁的不同。内部威胁可加强人们原有的政治倾向, 外部威胁可使人们更趋向保守。未来研究应在内外部威胁影响政治倾向变化的机制、政治倾向的本土化研究以及促进不同政治倾向个体间的和谐关系上做出努力。     

Terrorism and the Uses of Terror

“Terrorism”' is sometimes defined as a “form ofcoercion.” But there are important differences between ordinary coercion and terrorist intimidation. This paper explores some of those differences, particularly the relation between coercion, on the one hand, and terror and terrorization, on the other hand. The paper argues that while terrorism is not necessarily associated with terror in the literal sense, it does often seek to instill a mental state like terror in the populations that it targets. However, the point of instilling this mental state is not necessarily coercive or intimidatory: one can try to instill terror as an act of punishment, or as an expressive or therapeutic act, or because one values the political consequences that might follow, or because one thinks terror is preferable, from an ethical point of view, to the inauthentic complacency that characterizes the targeted population at present. Though this paper asks questions about the definition of “terrorism,” these questions are not asked for their own sake. The quest for a canonical definition of “terrorism” is probably a waste of time. But asking questions which sound like questions of definition is sometimes a fruitful way of focusing our reflections on terrorism and organizing our response.

Intolerance of uncertainty and perceived threat

The present study examined the relations between dimensions of intolerance of uncertainty (i.e., desire for predictability and uncertainty paralysis) and perceptions of threat (i.e., perceptions of the probabilities and costs of future undesirable outcomes) in a sample of 239 college students. Uncertainty paralysis was positively associated with both perceived probabilities and perceived costs for negative outcomes. Desire for predictability was positively associated with perceived costs for negative outcomes but was not associated with perceived probabilities for negative outcomes. When probability estimates for low base rate outcomes were examined separately, desire for predictability was negatively associated with perceived probabilities. Finally, perceived threat partially mediated the relations between dimensions of intolerance of uncertainty and worry. The results of the present study suggest mechanisms through which dimensions of intolerance of uncertainty might lead to excessive worry.     

Stereotype threat and test performance: A primer for school psychologists

Ethical guidelines require school psychologists to ensure that their assessment practices are nondiscriminatory, but typical discussions on this topic neglect the possible discriminatory effects of cultural stereotypes on assessment results. Recent research on stereotype threat shows that students' knowledge of stereotype-based negative expectations about their test performance can depress their actual test performance. This paper discusses the range of conditions that promote stereotype threat and identifies important moderators and mediators of the phenomenon. Several practical suggestions are offered for school psychologists to consider when interviewing students, interpreting assessment results, and developing programs to increase schoolwide achievement.     

Of snakes and faces: An evolutionary perspective on the psychology of fear

Snakes and faces are unique stimuli because they are deeply grounded in evolutionarily shaped behavior systems. Snakes are the prototypical stimulus in a predatory defense system promoting escape from predators, which prepares primates for efficient processing, attentional priority, and rapid fear acquisition to snakes and other stimuli related to predation. The social submissiveness system plays a similar role on the social arena by promoting yielding to dominant individuals without jeopardizing the protection of the group. Supporting these theoretical propositions, empirical data from a research program spanning four decades demonstrate enhanced fear conditioning to snakes and threatening faces compared to neutral stimuli, as well as fast nonconscious processing of, and prioritized attention to, snakes and threatening faces. Human brain‐imaging data show that these effects are mediated by an extensive fear‐network centering on the amygdala.     

自我肯定方式降低高威胁后的消极情绪

通过两个研究考察肯定内部核心品质和肯定外部成就两种不同自我肯定方式对威胁后个体的影响。研究1发现,无论高威胁还是低威胁情境下,选择内部自我肯定的被试均显著多于选择外部自我肯定的被试。研究2发现,内部自我肯定能够在边缘显著水平上降低高威胁感知被试的自我消极情绪,并能够显著降低高威胁感知被试的一般消极情绪,而外部自我肯定不能达到相似效果。上述结果表明,无论在高威胁还是低威胁情境下,个体都更倾向于选择内部自我肯定;与外部自我肯定相比,内部自我肯定对降低个体高威胁情境下的消极情绪有积极作用。
