心血管对恐惧暴露的反应已被证明反映了恐惧材料的情绪处理程度，并以重要的方式与暴露治疗的结果相关。本研究探讨了焦虑对这种加工的影响。言语焦虑的受试者可视化恐惧场景10次试验。三组不同，根据他们是否从事放松，中立，或令人担忧的想法之前，每个场景介绍。虽然这三种类型的思维在思考期间对心血管活动没有影响，但担心组的受试者对恐惧图像的心率反应明显低于中立状态下的受试者，中立状态下的受试者对恐惧图像的反应明显低于放松状态。然而，焦虑组对图像的主观恐惧程度显著高于中性条件，放松组接近焦虑组的水平，与后两种条件无显著差异。结果表明，担心可能会抑制情绪处理，从而保持认知/情感恐惧结构，并讨论了灰色的（行为和脑科学，5，469-534，1982）理论的行为抑制系统和语义饱足效应在认知心理学。
Cardiovascular response to phobic exposures has been shown to reflect the degree of emotional processing of phobic material and relates in important ways to outcome in exposure therapy. The present study investigated the effect of worry on such processing. Speech anxious subjects visualized a phobic scene for 10 trials. Three groups differed according to whether they engaged in relaxed, neutral, or worrisome thinking just prior to each scene presentation. Although the three types of thinking had no effect on cardiovascular activity during the thinking periods, subjects in the worry group displayed significantly less heart rate response to the phobic image than those in the neutral condition who had significantly less response than the relaxed condition. However, the worry group showed significantly greater subjective fear to the images than the neutral condition, with the relaxed group near to the level of the worry group and not signfiicantly different from either of the ohter two conditions. The results suggest that worry may inhibit emotional processing and thus preserve cognitive/affective fear structure, and are discussed in terms of Gray''s (Behavioural and Brain Sciences, 5, 469-534, 1982) theory of the behavioral inhibition system and semnatic satiation effects in cognitive psychology.
