Abstract

Presenting unpaired unconditional stimuli (US) during extinction training reduces the renewal of conditional fear due to context change. The present study investigated whether this reduced return of fear is specific to the aversive US presented during acquisition or can also be observed after extinction with unpaired presentations of another aversive or of a non-aversive US. Using an ABA renewal paradigm that trained extinction in a context different from that of the acquisition, renewal and re-acquisition test phases, participants received five unpaired presentations of either the aversive US used during acquisition (Group Aversive-Same), an aversive US not presented during acquisition (Group Aversive-Different) or a non-aversive US (Group Non-aversive) during extinction training. Renewal of electrodermal conditional responses was observed in group Non-aversive, but not in groups Aversive-Same or Aversive-Different. Re-acquisition did not differ across the groups. These results are consistent with a valenced arousal account to explain the effects of unpaired presentations of the US during extinction training which would suggest that extinction learning is enhanced under conditions of increased aversive arousal.

在消退过程中出现的非配对无条件刺激的更新减少效应并不局限于习得过程中使用的无条件刺激。

在灭绝训练中呈现非配对无条件刺激（US）减少了由于环境变化而导致的条件恐惧的更新。本研究调查了这种减少的恐惧回归是特定于习得期间呈现的厌恶美国，还是也可以在另一种厌恶美国或非厌恶美国的不配对呈现后被观察到。使用ABA更新范式，在不同于习得、更新和再习得测试阶段的背景下训练消退，参与者接受了五种不配对的呈现，分别是习得期间使用的厌恶美国（组厌恶-相同）、习得期间未出现的厌恶美国（组厌恶-不同）或消退训练期间的非厌恶美国（组非厌恶）。非厌恶性组皮肤条件反应出现更新，而厌恶性-相同组和厌恶性-不同组皮肤条件反应未出现更新。再习得在各组之间没有差异。这些结果与一种有价性唤醒解释一致，该解释解释了在灭绝训练期间美国的非配对呈现的影响，这表明在厌恶唤醒增加的条件下，灭绝学习得到了增强。

期刊介绍： The major focus of Behaviour Research and Therapy is an experimental psychopathology approach to understanding emotional and behavioral disorders and their prevention and treatment, using cognitive, behavioral, and psychophysiological (including neural) methods and models. This includes laboratory-based experimental studies with healthy, at risk and subclinical individuals that inform clinical application as well as studies with clinically severe samples. The following types of submissions are encouraged: theoretical reviews of mechanisms that contribute to psychopathology and that offer new treatment targets; tests of novel, mechanistically focused psychological interventions, especially ones that include theory-driven or experimentally-derived predictors, moderators and mediators; and innovations in dissemination and implementation of evidence-based practices into clinical practice in psychology and associated fields, especially those that target underlying mechanisms or focus on novel approaches to treatment delivery. In addition to traditional psychological disorders, the scope of the journal includes behavioural medicine (e.g., chronic pain). The journal will not consider manuscripts dealing primarily with measurement, psychometric analyses, and personality assessment.
