本研究探讨了促进任务处理灵活性的条件是否会增强无关负刺激对绩效的不利影响。我们从短暂和持续的角度来探讨这种灵活性，通过操纵参与者在连续试验中是否重复或在两个任务之间切换，以及他们是否在单独的区块或随机混合中执行任务。参与者将一个字母或一个条形图的颜色分类，这些颜色靠近不相关的负面或中性图片。在负面图片而不是中性图片的情况下，表现更差。在三个实验中，短暂地重复或切换任务并没有调节情感分心的不利影响（nExp1= 32，nExp2= 32，nExp3= 64）。注意捕获的负面内容没有下降相比，在单一的混合任务的背景下，但只有当这些持续的任务背景下，也不同的频率的情感刺激。当情感刺激在混合和单一任务的情况下是相同的，这种调制消失。总体而言，这些结果表明，任务无关的负面刺激对性能的影响是令人惊讶的独立的认知状态，有利于灵活或稳定的任务相关信息的处理。
This study explored whether conditions that promote flexibility in task processing enhance the detrimental impact of irrelevant negative stimulation on performance. We approached this flexibility from a transient and a sustained perspective, by manipulating whether participants repeated or switched between two tasks in consecutive trials and whether they performed the tasks in separate blocks or randomly mixed. Participants categorised either a letter or the colour of a bar, which were presented close to an irrelevant negative or neutral picture. Performance was worse in the presence of negative rather than neutral pictures. Repeating or switching tasks transiently did not modulate this detrimental impact of affective distraction in three experiments (nExp1= 32,nExp2= 32,nExp3= 64). Attentional capture by negative content did decline in single compared to mixed task contexts, but only when these sustained task contexts also differed in the frequency of affective stimulation. When affective stimulation was the same in mixed and single task contexts, this modulation vanished. Overall, these results suggest that the influence of task-irrelevant negative stimulation on performance is surprisingly independent of cognitive states that favour either flexible or stable processing of task-relevant information.
