摘　　要：目的：探究听障学生基于工作记忆内容的视觉注意捕获特征。方法分别选取20名听障学生和健听学生，采用双任务范式，要求被试在工作记忆保持阶段完成注意探测任务。结果相对于健听学生，听障学生基于图形表征的注意捕获反应时更快。结论在工作记忆内容保持阶段听障学生的视觉通路表现出一定的敏感性。Objective To explore the characteristics of the capture of visual attention based on working memory in hearing-impaired students. Methods Twenty hearing-impaired students and twenty normal-hearing students were recruited to participate in the study. A dual-task paradigm was used and the subjects were asked to complete the attentional capture task during working memory maintainance. Results The attentional capture reaction of hearing-impaired students based on graphical representation was faster than that of normal-hearing students. Conclusion The visual pathway of hearing-impaired students is sensitive during working memory maintainance.
