采用双任务范式使被试将工作记忆信息保存在工作记忆当中并完成选择性注意任务,结果发现:视觉空间工作记忆负荷不能使熟悉面孔的干扰效应消失,语义工作记忆负荷使熟悉面孔的干扰效应在高知觉负荷条件下消失.因此,熟悉面孔在高知觉负荷条件下可能是以语义的方式存储在工作记忆当中,在低知觉负荷条件下可能是同时存储在视觉空间工作记忆和语义工作记忆中.

The previous study found that interference from famous faces is not eliminated by high perceptual load.In this study,a dual-task paradigm was adopted,in which the subjects should keep verbal or spatial information in their WM(working memory) before they finished the Flanker task.The results showed that the spatial working memory load did not affect the interference from famous faces regardless of the perceptual load amount;by contrast,the verbal working memory load could eliminate the interference from famous faces at high perceptual load,but not at low perceptual load.These results suggested that the famous faces can be represented flexibly in verbal or visual modality at low perceptual load,but only in verbal modality at high perceptual load.
