Abstract

Fear conditioning studies have occurred mostly in the laboratory, but recently researchers have started to adapt fear conditioning procedures for remote application. Standardization of aversive stimulus material not causing unnecessarily strong discomfort remains an issue especially relevant to research without experimental supervision. The present study introduces a novel semi-subjective method to calibrate aversive sounds in a remotely conducted fear conditioning paradigm. To demonstrate feasibility and proof of concept, 165 participants completed the paradigm, calibrating the loudness of an aversive sound without the guidance of an experimental instructor. This study also aimed to replicate existing findings of participant groups that differed in their early CS-UCS contingency awareness. Participants were classified as Accurate (UCS more likely after the CS+ than CS-), Poor (UCS more likely after the CS- than CS+, or UCS unlikely after either CS), and Threat Biased (UCS equally likely after the CS+ and CS-). Results indicated both the feasibility and efficacy of the paradigm, with participants showing typical patterns of fear learning. Threat Biased participants showed significantly higher uncertainty towards safety signals. There were no differences between the groups in terms of personality traits, thus questioning whether these attributes mediate differences in fear learning and the emergence of anxiety disorders. Using semi-subjective sound calibration appears to be functional, and future studies may consider implementing the new method when remotely administering fear conditioning paradigms.

校准你自己的恐惧:具有半主观刺激校准和恐惧学习差异的远程恐惧条件反射范式的可行性。
恐惧条件反射研究大多在实验室进行,但最近研究人员开始将恐惧条件反射程序应用于远程应用。不引起不必要的强烈不适的厌恶性刺激材料的标准化仍然是一个问题,尤其与没有实验监督的研究有关。本研究介绍了一种新的半主观方法来校准远程传导恐惧条件反射范式中的厌恶声音。为了证明可行性和概念验证,165名参与者完成了该范式,在没有实验教师指导的情况下校准厌恶声音的响度。本研究还旨在复制参与者群体在早期CS-UCS应急意识方面存在差异的现有发现。参与者被分为准确(CS+后UCS比CS-更有可能)、差(CS-后UCS比CS+更有可能,或CS后UCS不太可能)和威胁偏好(CS+和CS-后无UCS同样可能)。结果表明了该范式的可行性和有效性,参与者表现出典型的恐惧学习模式。有威胁偏见的参与者对安全信号表现出明显更高的不确定性。两组之间在性格特征方面没有差异,因此质疑这些特征是否在恐惧学习和焦虑症的出现方面起到了中介作用。使用半主观声音校准似乎是可行的,未来的研究可能会考虑在远程管理恐惧条件反射范式时实施新方法。
