Positive affect predicts less reacquisition of fear: relevance for long-term outcomes of exposure therapy

Much emphasis in fear conditioning research is placed on understanding extinction learning, partly because of its application in treating anxiety disorders. Return of fear after extinction is a problem affecting long-term maintenance of treatment gains. The present study evaluated whether positive affect (PA) is associated with lower rates of reacquisition, or, an increase in fear following re-pairings of the conditional stimulus (CS+) and unconditional stimulus (US; e.g. electric shock) after extinction. Results showed that higher PA before and after extinction was associated with less CS+ fear during reacquisition as measured by skin conductance arousal and US expectancy. Conversely, negative affect was not associated with reacquisition of fear using any measure. These results provide implications for reducing reacquisition with exposure therapy for anxiety disorders.     

分类和概念对恐惧泛化的影响机制

恐惧泛化与多种焦虑障碍的病理基础密切相关。例如创伤后应激障碍个体往往持续地逃避与创伤事件有关的刺激,遭受着创伤痛苦折磨。本文在厘清知觉辨别与恐惧泛化关系的基础上,着力于高级认知过程(分类与概念相似性、典型性和人工概念)对恐惧泛化的影响,回顾了恐惧泛化的相关神经机制,并揭示恐惧泛化对焦虑障碍患者的临床治疗启示。未来研究应将知觉和高级认知维度的恐惧泛化进行整合研究,同时扩充恐惧习得和泛化的神经回路,以促进人类恐惧泛化更深入的研究。     

Return of fear in a human differential conditioning paradigm caused by a return to the original acquistion context

In a differential human fear conditioning paradigm evidence for ABA-renewal was obtained manipulating the lighting in the experimental room. During acquisition in either a dark or illuminated room, one neutral slide was sometimes paired with a loud aversive noise whereas another slide was not. Subsequently, extinction took place in the opposite lighting context. When afterwards the participants were tested again in the original acquisition context, measurements revealed a recovery of the conditioned electrodermal response and an increase in the retrospective verbal US-expectancy ratings. No response recovery was obtained in an AAA-group that received acquisition, extinction and test trials in one and the same context. Several theoretical explanations for this type of return of fear as well as implications for clinical practice are discussed.     

Grace and Imagination: From Fear to Freedom

Creative use of our imagination is essential if we are to live a vibrant life. Although our use of imagination is often blocked by various fears, D. W. Winnicott's insights into play, aggression, and the use of transitional objects open up paths towards greater freedom. The sacred texts, symbols, and liturgies of our religious traditions can then become the toys which engage us in profound and re-creating soul play. Through grace and the evocative examples of our teachers, we can find ways to use our imagination more freely to deepen our spiritual life and psychological wholeness.     

Intrahippocampal scopolamine impairs both acquisition and consolidation of contextual fear conditioning

Lesions of the dorsal hippocampus have been shown to disrupt both the acquisition and the consolidation of memories associated with contextual fear (fear of the place of conditioning), but do not affect fear conditioning to discrete cues (e.g., a tone). Blockade of central muscarinic cholinergic receptor activation results in selective acquisition deficits of contextual fear conditioning, but reportedly has little effect on consolidation. Here we show for the first time that direct infusion of the muscarinic cholinergic receptor antagonist, scopolamine, into the dorsal hippocampus produces a dose-dependent deficit in both acquisition and consolidation of contextual fear conditioning, while having no impact on simple tone conditioning.     

Worth the risk? Fear of being single and willingness to make risky health decisions in sex and dating contexts

Does fear of being single (FOBS) predict risky health behaviors when such behavior could promote pursuit of a romantic connection? Study 1 tested general tendencies toward taking health risks associated with FOBS. Study 2 tested how those with stronger FOBS navigated romantic versus non-romantic risk behavior during the COVID-19 pandemic. Study 3 extended the test of risky behavior beyond the pandemic to test whether FOBS was associated with willingness to engage in risky sexual behavior. Despite nonsignificant associations with taking health risks more generally, FOBS was associated with greater willingness to engage in risky behaviors in dating contexts, particularly when considering their willingness to settle for less in relationships. This research provides novel insight into dating choices associated with stronger FOBS and how willingness to settle predicts risky health behavior when it could appeal to romantic prospects.     

Fight and Flight: Evidence of Aggressive Capitulation in the Face of Fear Messages from Terrorists

In an era of digital technology and the Internet, terrorists can communicate their threats directly to citizens of Western countries. Yet no research has examined whether these messages change individuals' attitudes and behavior or the psychological processes underlying these effects. Two studies (conducted in 2008 and 2010) examined how American, Australian, and British participants responded to messages from Osama bin Laden that threatened violence if troops were not withdrawn from Afghanistan. Heightened fear in response to the message resulted in what we call “aggressive capitulation,” characterized by two different group‐protection responses: (1) submission to terrorist demands in the face of threats made against one's country and (2) support for increased efforts to combat the source of the threat but expressed in abstract terms that do not leave one's country vulnerable. Fear predicted influence over and above other variables relevant to persuasion. Theoretical and practical implications are discussed.     

AN ANALYST'S UNCERTAINTY AND FEAR

The motivations for choosing psychoanalysis as a profession are many and differ depending on the psychology of the analyst. However, common to most psychoanalysts is the desire to forge a helpful relationship with the individuals with whom they work therapeutically. This article presents an example of what happens when an analyst is confronted by a patient for whom being in a relationship and being helped are intolerable.     

Fear,Functioning, and Coping During Exposure to a Continuous Security Threat

This study focused on the contribution of fear to mediating stress, as manifested in general stress reactions and impaired functioning resulting from exposure to a continuous security threat among 451 students from a college located in a confrontation zone. The findings indicated that the contribution of fear reactions was more significant than actual exposure. Married participants felt higher levels of fear than did single participants, and women were able to function despite their fear. In addition, coping patterns were both directly and indirectly related to all stress measures. The results are discussed in light of the literature on stress reactions, and practical recommendations for working in continuous threat situations are proposed.     

Post-traumatic stress symptoms in adolescents exposed to an earthquake: Association with self-efficacy,perceived magnitude,and fear

The objective of this study was to evaluate th×e relationship between the magnitude of an earthquake, the fear experienced, the self-efficacy beliefs, and post-traumatic stress symptoms in adolescents. We expected self-efficacy beliefs to predict post-traumatic stress symptoms, and this relation to be mediated by fear. We used data from a longitudinal project on adolescent normative development that was under way at the time of the 2010 earthquake in Chile. Six months before the earthquake, 218 adolescents responded to a self-efficacy beliefs scale; three months after the earthquake they reported the perceived magnitude of the event, the fear they experienced, and their post-traumatic stress symptoms. Results showed that perceived magnitude was not associated with fear or post-traumatic stress symptoms, but self-efficacy beliefs and fear were associated with post-traumatic stress symptoms. The hypothesized role of fear as a mediator in the relation between self-efficacy beliefs and post-traumatic stress symptoms was supported by the data. The results of the study, suggest that preventive interventions aimed to increase awareness of how to face a disaster may not only contribute to save lives but may also increase adolescentś sense of personal efficacy, reducing subsequent emotional reactivity associated with the event.
