According to recent theoretical approaches dispositional anxiety is fundamentally linked to neural mechanisms of cognitive control (Braver et al., 2007; Eysenck et al., 2007). The present study was conducted to further investigate this topic by focusing on the relation between trait anxiety, conflict-processing and dynamic adjustments in attentional allocation. Participants completed a modified version of the face-word Stroop task while an electroencephalogram was recorded. We analyzed behavioral and electrophysiological correlates of conflict processing and conflict-driven modulations in target and distractor processing. Anxiety was not related to general conflict-sensitivity but to individual differences in conflict-driven adjustments in attentional allocation: following a high level of stimulus-response conflict, highly anxious participants allocated more attentional resources to the processing of predominantly task-relevant information and withdrew attention from the processing of predominantly task-irrelevant information. Thus, trait anxiety appears to be closely related to individual differences in dynamic adjustments of attentional control.
根据最近的理论方法，特质焦虑从根本上与认知控制的神经机制有关（Braver 等人，2007；Eysenck 等人，2007）。本研究通过关注特质焦虑、冲突处理和注意力分配的动态调整之间的关系，进一步探讨了这一主题。参与者在记录脑电图的同时完成了面部词汇斯特鲁普任务的修改版。我们分析了冲突处理和目标和干扰处理中冲突驱动的调制的行为和电生理相关性。焦虑与一般冲突敏感性无关，而与注意力分配中冲突驱动调整的个体差异有关：在高刺激-反应冲突后，高度焦虑的参与者将更多的注意力资源分配给主要与任务相关的信息处理，并从主要与任务不相关的信息处理中撤回注意力。因此，特质焦虑似乎与注意力控制的动态调整的个体差异密切相关。
