通过记录和分析被试的行为和眼动指标,本研究试图探讨不同工作记忆负荷下,形状干扰对聋人与听力正常人不同视野位置上刺激信息捕获注意的异同。研究结果表明:(1)形状干扰刺激虽然没有影响被试视觉加工的认知绩效,但被试的眼动模式会由于工作记忆负荷的改变而改变,高工作记忆负荷时,有形状干扰的注视次数高于无形状干扰。(2)工作记忆负荷、视野位置影响被试视觉加工任务的完成,被试在不同视野位置的加工过程表现出不一致的眼动模式。(3)聋人视觉加工在高工作记忆负荷时存在一定的劣势,但其对不同视野位置的信息加工及形状干扰所产生的注意捕获效应与听力正常人一致。
By recording and analyzing the behavioral and ophthalmic indexes of the participants, this study attempts to explore the similarities and differences of shape interference on the capture of stimulus information in different field of vision of deaf and normal hearing persons under different working memory load. The results showed that: (1) Although the shape-disturbing stimulus did not affect the cognitive performance of the participants in the visual processing, the eye movement patterns of the subjects changed due to the change of the working memory load. When the working memory load was high, Times higher than without shape interference. (2) The working memory load and visual field position affected the completion of visual processing tasks, and the subjects showed inconsistent eye movement patterns during processing in different visual fields. (3) Visual processing of deaf has some disadvantage in high working memory load, but the attention capture effect of information processing and shape interference of different visual field positions is consistent with normal hearing people.
