背景和目标：短暂焦虑反应后的冲动选择是一个潜在的重要结果，可能是与高水平社交焦虑同时发生的适应不良行为模式的基础。然而，很少有研究探讨冲动选择与。社交焦虑Rounds，Beck and Grant（2007; Behavior Research and Therapy，45，729-735）使用延迟折扣程序发现，高社交焦虑与冲动选择相关，但仅在非威胁（对照）条件下，但该研究中的几个程序混淆也可以解释该发现。本研究的目的是复制回合等。同时控制潜在的程序confounds.Methods：高，低社交焦虑的成年大学生，没有药物滥用的历史被随机分配到一个公开演讲的条件或控制（沉默阅读）的条件。在中间的任务，参与者完成了一项措施的延迟折扣，措施的冲动choice.Results：冲动的选择是不受任何社会焦虑状态或实验condition.Limitations：冲动的选择的其他方面可能会更敏感，短暂的焦虑和恐惧。更高的社交焦虑和短暂焦虑水平可能是必要的，以检测与冲动选择的显着关系。相对高水平的冲动反应可能只会发生在社会焦虑的个人与当前/历史substance abuse.Conclusions：无论是anxiogenic实验室程序，也不社会焦虑状态出现影响冲动的选择延迟折扣任务测量。未来的研究可能会考虑检查短暂的焦虑是否会影响冲动选择的其他方面。爱思唯尔有限公司出版
Background and objectives: Impulsive choice that follows transient anxiety responses is a potentially important outcome that may underlie maladaptive behavioral patterns that co-occur with high levels of social anxiety. However, little research has examined impulsive choice in relation to. social anxiety. Rounds, Beck and Grant (2007; Behavior Research and Therapy, 45, 729-735) found that high social anxiety was associated with impulsive choice using a delay discounting procedure, but only in a non-threatening (control) condition, but several procedural confounds in that study may also explain the findings. The purpose of this study was to replicate Rounds et al. while controlling for potential procedural confounds.Methods: High- and low-social anxiety adult college-students with no substance abuse history were assigned randomly to a public speaking condition or a control (silent reading) condition. In the middle of the task, participants completed a measure of delay discounting, which measures impulsive choice.Results: Impulsive choice was not influenced by either social anxiety status or experimental condition.Limitations: Other aspects of impulsive choice may be more sensitive to transient anxiety and fear. Higher state levels of social anxiety and transient anxiety may be necessary to detect a significant relationship with impulsive choice. Relatively high levels of impulsive responding may only occur in socially anxious individuals with current/historical substance abuse.Conclusions: Neither anxiogenic laboratory procedures nor social anxiety status appear to influence impulsive choice as measured by the delay discounting task. Future research might consider examining whether transient anxiety influences other aspects of impulsive choice. Published by Elsevier Ltd.
