这项研究使用一种改进的探测任务，调查了广泛性焦虑症(GAD)和抑郁症患者对情绪面孔刺激的选择性注意的偏差。有4种面孔类型：威胁型、忧郁型、喜怒型。而且是中立的。注意力偏向的测量包括(A)最初眼球运动的方向和潜伏期对面孔的反应，以及(B)在刺激开始后1000ms对探头代替面孔刺激的手动反应时间(RT)。结果显示，与正常对照组和抑郁障碍患者相比，患有GAD(没有抑郁障碍)的人更有可能首先看到威胁面孔，而不是中性面孔。与其他两组人相比，他们也更快地将目光转向威胁面孔，而不是远离他们。从手动RT数据中没有明显的发现。这一结果对最近的临床焦虑和抑郁理论的意义进行了讨论。
The study investigated biases in selective attention to emotional face stimuli in generalized anxiety disorder (GAD) and depressive disorder, using a modified probe detection task. There were 4 face types: threatening, sad, happy. and neutral. Measures of attentional bias included (a) the direction and latency of the initial eye movement in response to the faces and (b) manual reaction time (RT) to probes replacing the face stimuli 1,000 ms after their onset. Results showed that individuals with GAD (without depressive disorder) were more likely to look first toward threat faces rather than neutral faces compared with normal controls and those with depressive disorder. They also shifted their gaze more quickly toward threat faces, rather than away from them, relative to the other two groups. There were no significant findings from the manual RT data. Implications of the results for recent theories of clinical anxiety and depression are discussed.
