• W1520714979 abstract "Event Abstract Back to Event Object perception is selectively slowed by a visually similar working memory load Alan Robinson1, Alberto Manzi2, 3 and Jochen Triesch4* 1 University of California, United States 2 Second University of Naples, Italy 3 New York State Psychiatric Institute, United States 4 Frankfurt Institute for Advanced Studies, Germany While visual working memory has been extensively characterized in terms of its capacity (Alvarez & Cavanagh, 2004), little work has investigated how holding an object in visual memory influences concurrent cognition and perception. Interestingly, brain areas that support visual object recognition are also actively involved in visual working memory, suggesting potential interference between these processes. In this study, we tested whether a visual working memory load slows down perception of similar objects during the retention period. Subjects judged the gender of computer rendered faces or the naturalness of body postures while also holding either faces or body postures in memory. Perceptual discriminations were slowed by several tens of milliseconds when stimuli of the same class (faces or bodies) rather than those of the other class were maintained in memory. We also found that subjects are particularly slow to judge the gender of faces, when they hold a face of the same gender in working memory. Interestingly, this is the opposite of what would be predicted from traditional priming. Our results suggest that there is interference between visual working memory and perception caused by visual similarity between new perceptual input and items already encoded in working memory. This interference may be one of the reasons why subjects often do not seem to use their working memory to its full capacity in natural tasks (Droll et al., 2005). References 1.
