从思维内容和思维时间效价的角度，通过实验操作，考察了反刍对注意广度的差异效应。我们将68名本科生和研究生随机分为消极、中立、长期和短期思维组。然后，我们进行了问卷调查，进行了反刍操作和改进的注意广度任务。在该任务中，存在根据目标刺激的位置而具有窄的和宽的注意范围的近和远条件，并且计算表示在近和远条件下对目标的正确响应率之间的差异的Δ注意缩小指数（ΔANI），使得ΔANI值越高表示越窄的注意范围。结果表明，当被试长时间专注于消极思想时，状态反刍和消极情绪恶化，注意广度下降。此外，反刍和注意广度之间的因果关系。此外，通过反刍缩小注意广度的因素被确定的基础上的注意范围模型。未来的研究应该考虑是否抑郁或消极的认知加工恶化，缩小注意广度。
The differential effects of rumination on attentional breadth was investigated by experimentally manipulating rumination from the perspective of thought content and valences of thinking-time. We randomly assigned 68 undergraduate and graduate students to negative, neutral, long-, and short-time thinking groups. Then, we administered a questionnaire, conducted a rumination manipulation and the modified Attentional Breadth Task. In this task, there are Close and Far conditions that have a narrow and wide attentional range depending on the location of the target stimulus, and ΔAttentional Narrowing Index (ΔANI) representing the differences between the correct response rate for a target in Close and Far conditions are calculated, such that higher ΔANI values indicate a narrower attention range. Results indicated that state rumination and negative emotions worsened and attentional breadth decreased when participants focused on negative thoughts for a long time. Moreover, a causal relationship between rumination and attentional breadth was suggested. Also, factors narrowing attentional breadth through rumination were identified based on the attentional scope model. It is suggested that future studies should consider whether depression or negative cognitive processing is worsened by narrowing attentional breadth.
