In the typical Stroop task, participants are presented with color words written in different ink colors and are asked to respond to their color. It has been suggested that the Stroop task consists of two main conflicts: information conflict (color vs. word naming) and task conflict (respond to color vs. read the word). In the current study, we developed a novel task that includes both Response trials (i.e., trials in which a response is required) and Rest trials (i.e., trials in which no response is required or available) and investigated the existence of both information and task conflicts in Rest trials. We found evidence for task conflict in Response and also in Rest trials, while evidence for information conflict was only observed in Response trials. These results are in line with a model of task conflict that occurs independently of and prior to information conflict in the Stroop task.
在典型的斯特鲁普任务中，参与者会看到用不同颜色墨水书写的颜色词，并被要求对其颜色做出反应。有人认为，斯特鲁普任务包括两种主要冲突：信息冲突（颜色与词语命名）和任务冲突（对颜色做出反应与阅读词语）。在本研究中，我们开发了一种新的任务，它同时包含反应试次（即需要做出反应的试次）和休息试次（即不需要或无法做出反应的试次），并研究了在休息试次中是否存在信息和任务冲突。我们在反应试次和休息试次中都发现了任务冲突的证据，而信息冲突的证据仅在反应试次中观察到。这些结果与斯特鲁普任务中任务冲突独立于信息冲突并先于信息冲突发生的模型一致。
