在经典Stroop范式中，增加控制要求不一致试验的比例会导致行为和认知控制过程的策略调整。我们操纵期望不一致的试验中的情绪面部Stroop任务调查的行为和神经的影响比例操纵的认知要求任务与情绪刺激。受试者在功能性磁共振成像（fMRI）期间执行高期望（HE）任务（65%不一致试验）和低期望（LE）任务（35%不一致试验）。在标准的Stroop任务，行为干扰减少情绪面部Stroop HE任务相比，LE任务。功能性MRI数据显示，在认知控制策略的开关，从反应性，事件相关的激活的内侧和外侧认知控制网络和右杏仁核在LE任务的积极主动，持续激活的右背外侧前额叶皮层（DLPFC）在HE任务。较高的特质焦虑与损伤（反应时间较慢，准确性下降），以及减少活动的左腹外侧前额叶皮层，前额叶皮层，眶额皮层在HE任务的高冲突试验与任务无关的情绪信息，这表明焦虑的个体差异可能与预期相关的战略控制调整，特别是当情绪刺激必须被忽略。
In classic Stroop paradigms, increasing the proportion of control-demanding incongruent trials results in strategic adjustments in behavior and implementation of cognitive control processes. We manipulated expectancy for incongruent trials in an emotional facial Stroop task to investigate the behavioral and neural effects of proportion manipulation in a cognitively demanding task with emotional stimuli. Subjects performed a high expectancy (HE) task (65% incongruent trials) and a low expectancy (LE) task (35% incongruent trials) during functional magnetic resonance imaging (fMRI). As in standard Stroop tasks, behavioral interference was reduced in the emotional facial Stroop HE task compared to the LE task. Functional MRI data revealed a switch in cognitive control strategy, from a reactive, event-related activation of a medial and lateral cognitive control network and right amygdala in the LE task to a proactive, sustained activation of right dorsolateral prefrontal cortex (DLPFC) in the HE task. Higher trait anxiety was associated with impairment (slower response time and decreased accuracy) as well as reduced activity in left ventrolateral prefrontal cortex, anterior insula, and orbitofrontal cortex in the HE task on high conflict trials with task-irrelevant emotional information, suggesting that individual differences in anxiety may be associated with expectancy-related strategic control adjustments, particularly when emotional stimuli must be ignored.
