Eysenck（1997）的理论认为，威胁的注意偏向是特质焦虑和防御性的交互作用的结果。使用两种刺激暴露条件来探索有关随着时间的推移注意力分配的次要问题。结果表明，在高特质焦虑的参与者中，只有那些低水平的防御性表现出警惕的威胁性面孔提出了500毫秒。他们还表现出注意力偏好中性的面孔，相对于快乐的面孔，无论暴露条件。这种模式被逆转的高特质焦虑的参与者与高水平的防御，谁表现出对快乐的面孔（相对于中性面孔）在这两个曝光条件下的注意力偏差。研究结果进行了讨论，他们的影响（a）的防御措施的概念化的高特质焦虑的个人的意义，和（B）焦虑相关的偏见在不同阶段的信息处理的状态。(C)2003爱思唯尔有限公司。保留所有权利。
Eysenck's (1997) theory that attentional biases for threat vary as an interactive function of trait anxiety and defensiveness was tested using a visual probe task. Two stimulus exposure conditions were used to explore a secondary issue concerning attentional allocation over time. Results indicated that, among high trait anxious participants, only those with low levels of defensiveness showed vigilance for threatening faces presented for 500 ms. They also showed an attentional preference for neutral faces, relative to happy faces, irrespective of exposure condition. This pattern was reversed in high trait anxious participants with high levels of defensiveness, who showed an attentional bias towards happy faces (relative to neutral faces) under both exposure conditions. The findings are discussed in relation to their implications for (a) the significance of measures of defensiveness for the conceptualization of high trait anxious individuals, and (b) the status of anxiety-related biases at different stages of information processing.
