分心是一种普遍存在的心理现象,指注意力从当前任务目标有关的刺激和心理标准转移到与任务无关的其他刺激或表征。目前研究者一般采用主观报告法评估任务中被试的分心频率。通过对分心研究中使用的主观报告法进行分析发现,主观报告法的效度是可以得到保证的,但需要严格控制实验条件。 Distraction is a ubiquitous psychological phenomenon in which attention is diverted from the stimuli and psychological criteria associated with the current mission objective to other stimuli or representations unrelated to the task. At present, researchers generally use the subjective reporting method to assess the subjects’ distraction frequency in the task. Through the analysis of the subjective reporting method used in the distractions study, the validity of the subjective reporting method can be guaranteed, but the experimental conditions need to be strictly controlled.
