越来越多的研究指出，焦虑的个体可能难以将注意力从与任务无关的威胁相关信息中解脱出来（例如，Amir， N., & Elias， J.(2002)）。社交恐惧症中对威胁的注意分配：从任务无关线索中脱离的困难。季刊J. Exp. Psycho. 54A(2001) 665)。在当前的论文中，我们报告了在社交恐惧症患者中对这一假设的直接测试。参与者进行了波斯纳范式的变化(夸脱。《精神病学杂志》32(1980)3)。社会威胁、中性或积极的词语提示电脑屏幕上的两个位置之一。在提示消失后，参与者必须在两个位置中的一个位置发现一个探针（“*”）。在一些试验中，提示是有效的（即，探针出现在与提示相同的位置）。在其他试验中，提示无效（探针出现在与提示不同的位置）。然而，在其他试验中，没有提示。所有参与者在发现无效线索的探针时都比发现有效线索的探针慢。此外，与对照组相比，社交恐惧症患者在检测无效提示目标时表现出明显更长的反应延迟，但仅限于当探针跟着一个社交威胁词时。这些结果表明，患有社交恐惧症的人可能很难将注意力从社交威胁材料上移开。(C) 2003, Elsevier Ltd.出版
There is a growing body of research pointing to the possibility that anxious individuals may have difficulty disengaging their attention from threat-relevant information when this information is task irrelevant (e.g., Amir, N., & Elias, J. (2002). Allocation of attention to threat in social phobia: difficulty in disengaging from task irrelevant cues, Manuscript under review; The Quarterly J. Exp. Psycho. 54A (2001) 665). In the current paper, we report a direct test of this hypothesis in individuals with social phobia. Participants performed a variation of the Posner paradigm (Quart. J. Exp. Psycho. 32 (1980) 3). Social threat, neutral, or positive words cued one of two locations on the computer screen. After the cue disappeared, participants had to detect a probe (''*'') that appeared in one of the two locations. On some trials the cue was valid (i.e., the probe appeared in the same location as the cue). On other trials the cue was invalid (the probe appeared in a different location than the cue). Yet, on other trials, no cue was presented. All participants were slower in detecting probes following invalid cues than probes following valid cues. Furthermore, individuals with social phobia showed significantly longer response latencies when detecting invalidly cued targets than did controls, but only when the probe followed a social threat word. These results suggest that individuals with social phobia may have difficulty disengaging their attention from socially threatening material. (C) 2003 Published by Elsevier Ltd.
