Although enhanced fear conditioning has been implicated in the origins of social anxiety disorder (SAD), laboratory evidence in support of this association is limited. Using a paradigm employing socially relevant unconditioned stimuli, we conducted two separate studies to asses fear conditioning in individuals with SAD and non-clinical individuals with high social anxiety (subclinical social anxiety [SSA]). They were compared with age-matched and gender-matched individuals with another anxiety disorder (panic disorder with agoraphobia) and healthy controls (Study 1) and with individuals with low social anxiety (Study 2). Contrary to our expectations, in both studies, self-report measures (ratings of anxiety, unpleasantness and arousal to the conditioned stimuli) of fear conditioning failed to discriminate between SAD or SSA and the other participant groups. Our results suggest that enhanced fear conditioning does not play a major role in pathological social anxiety.
We used a social conditioning paradigm to study fear conditioning in clinical and subclinical social anxiety. We found no evidence of enhanced fear conditioning in social anxiety individuals. Enhanced fear conditioning may not be a hallmark of pathological social anxiety.
尽管强化恐惧条件作用被认为与社交焦虑障碍(SAD)的发病有关,但支持这种关联的实验室证据有限。我们采用一种使用与社会相关的非条件刺激的范式,进行了两项独立研究,以评估SAD患者和具有高社交焦虑的非临床个体(亚临床社交焦虑[SSA])的恐惧条件作用。将他们与年龄和性别匹配的患有另一种焦虑障碍(伴有广场恐惧症的惊恐障碍)的个体以及健康对照者进行比较(研究1),并与社交焦虑程度低的个体进行比较(研究2)。与我们的预期相反,在两项研究中,恐惧条件作用的自我报告测量(对条件刺激的焦虑、不愉快和唤醒评分)均未能区分SAD或SSA与其他参与者组。我们的结果表明,强化恐惧条件作用在病理性社交焦虑中不发挥主要作用。
我们使用社会条件作用范式来研究临床和亚临床社交焦虑中的恐惧条件作用。我们没有发现社交焦虑个体存在强化恐惧条件作用的证据。强化恐惧条件作用可能不是病理性社交焦虑的标志。
