以心脏和皮肤电定向反应为指标，普遍的慢性焦虑已被证明会导致注意力缺陷。本研究试图针对不同程度的恐惧焦虑重复这些发现。患有恐惧症的志愿者会看到一张包含恐惧症内容的幻灯片，并同时呈现音调。恐惧是根据对幻灯片的最初心脏反应来定义的。初始心脏加速最明显的 Ss 也表现出长潜伏期心脏反应，在滑动开始后 20 秒左右达到峰值。与无反应者和“减速者”不同，“加速者”也会产生明显的心脏减速，并且与“减速者”一起对第一个音调产生皮肤电反应。结果与长期焦虑个体中发现的结果不一致，得出的结论是，根据威胁的来源，慢性焦虑状态和恐惧焦虑状态在注意力方向上有所不同，前者关注内部线索，后者关注环境线索。
Generalized, chronic anxiety has been shown to result in attentional deficits using cardiac and electrodermal orienting responses as indicators. The present study attempted to replicate these findings for different degrees of phobic anxiety. Phobic volunteers were exposed to a slide with phobic content and concurrently presented with tones. Fearfulness was defined in terms of the initial cardiac response to the slide. Ss with the most marked initial cardiac acceleration also exhibited a long-latency cardiac response peaking at around 20 sec after slide onset. Unlike-non-responders and ''decelerators, ''accelerators'' also yielded a marked cardiac deceleration and, together with ''decelerators'' an electrodermal response to the first tone. Results are at variance with those found in chronically anxious individuals and it is concluded that depending on the source of threat, chronic and phobic anxiety states differ with regard to direction of attention, focusing on internal cues in the former and on environmental cues in the latter.
