与另一个人一起完成一项任务可能会增强或减少与任务无关的信息产生的干扰。在三个实验中，我们使用Stroop类任务(即图片-单词干扰-PWI-TASK)的联合版本来研究当任务在两个人之间共享时，一些似乎对确定任务无关信息的效果至关重要的任务特征。参与者被要求完成一项PWI任务，这项任务要求说出一张图片的名字，同时忽略一个让人分心的单词，首先是单独的(在基线试验中)，然后与所谓的伴侣合作。结果表明，与基线和参与者继续单独执行PWI任务的情况相比，当这些单词是大小写交替字母(例如，鼠标)时，与另一个被认为负责分心单词的人合作的信念抑制了语义干扰效应。相反，当合作参与者被认为负责与参与者相同的任务时，语义干扰效应仍然存在，即合作参与者被认为对图片做出反应。这些结果的解释是假设，当参与者知道另一个人负责与任务无关的信息时，参与者和合作参与者之间可以建立分工。这种分工可以为参与者提供一种反对语义干扰效应的策略。因此，我们的发现表明，与另一个负责潜在干扰信息的人共享一项任务，可以使人们从自己的任务表征中过滤掉这些信息。
Performing a task with another person may either enhance or reduce the interference produced by task-irrelevant information. In three experiments, we employed the joint version of a Stroop-like task (i.e., the picture–word interference—PWI—task) to investigate some of the task features that seem to be critical in determining the effect of task-irrelevant information when the task is shared between two individuals. Participants were asked to perform a PWI task, which required to name a picture while ignoring a distractor word, first individually (in a baseline block of trials) and then co-acting with an alleged partner. Results showed that, compared to the baseline and to a condition in which participants continued to perform the PWI task individually, the belief of co-acting with another individual who was thought to be in charge of the distractor words suppressed the semantic interference effect when these words were in case alternation letters (e.g., “mOuSe”). Conversely, the semantic interference effect persisted when the co-actor was thought to be in charge of the same task as the participant, that is, the co-actor was thought to respond to the pictures. These results are accounted for by assuming that, when the participant knows that another person is in charge of the task-irrelevant information, a division-of-labour between participant and co-actor can be established. Such a division-of-labour may provide the participant with a strategy to oppose the semantic interference effect. Our findings, therefore, suggest that sharing a task with another person in charge of potentially interfering information can enable people to filter out this information from their own task representation.
