越来越多的证据表明，认知控制可以通过监测加工冲突作为在线控制需求的指标进行自适应调节。然而，目前尚不清楚自上而下的控制机制是否以特定于操作任务上下文的方式对处理冲突做出响应，或者赋予更普遍的益处。虽然以前的研究已经研究了冲突适应效应的任务集特异性，产生不一致的结果，控制相关的性能调整后的错误在很大程度上被忽视了。这一差距在文献中强调了最近的争论，是否错误后的表现代表了一种战略，控制介导的机制或注意力定向的非战略后果。在本研究中，广义控制的证据后，高冲突正确的尝试和错误的任务转换范式进行了探索。冲突的适应效果没有发现概括跨任务集，尽管共享的响应集。与此相反，错误后减慢效应被发现扩展到不活跃的任务集，并预测增强错误后的准确性。此外，错误后的性能调整被发现持续几次试验，并在多个任务切换，一个发现不一致的注意力定位帐户的错误后放缓。这些研究结果表明，错误相关的控制调整赋予一个普遍的性能效益，并建议分离的冲突后和错误后的控制机制。
There has been accumulating evidence that cognitive control can be adaptively regulated by monitoring for processing conflict as an index of online control demands. However, it is not yet known whether top-down control mechanisms respond to processing conflict in a manner specific to the operative task context or confer a more generalized benefit. While previous studies have examined the taskset-specificity of conflict adaptation effects, yielding inconsistent results, control-related performance adjustments following errors have been largely overlooked. This gap in the literature underscores recent debate as to whether post-error performance represents a strategic, control-mediated mechanism or a nonstrategic consequence of attentional orienting. In the present study, evidence of generalized control following both high conflict correct trials and errors was explored in a task-switching paradigm. Conflict adaptation effects were not found to generalize across tasksets, despite a shared response set. In contrast, post-error slowing effects were found to extend to the inactive taskset and were predictive of enhanced post-error accuracy. In addition, post-error performance adjustments were found to persist for several trials and across multiple task switches, a finding inconsistent with attentional orienting accounts of post-error slowing. These findings indicate that error-related control adjustments confer a generalized performance benefit and suggest dissociable mechanisms of post-conflict and post-error control.
