言语工作记忆负载与言语知觉负载对颜色无意视盲的影响

The Influence of the Verbal Working Memory Load and Verbal Perceptual Load to Inattention Blindness of Color

无意视盲是指当人们专注于某事时,往往注意不到出现在眼前的其它刺激的现象。本研究以工作记忆的多重加工系统为出发点,操纵了言语工作记忆负载和言语知觉负载,使得工作记忆占用资源与目标刺激加工所需资源相同,均属于言语加工任务,而干扰刺激是颜色,属于颜色加工任务。本研究将工作记忆负载与知觉负载结合起来发现:两者都影响了颜色的无意视盲。

The phenomenon inattention blindness(IB)exists people focusing on something while unnoticing other stimulations appearing before eyes.Based on the multi-processing system of working memory,the study manipulated the verbal working memory load and verbal perceptual load,so that working memory occupied the same resources as target stimulus processing,which belonged to verbal processing task.However,the interference stimulus was color,which belonged to color processing task.The study combines working memory load with perceptual load and finds that both of them affect inattention blindness of color.
