Abstract Details

2020, Doctor of Philosophy, Case Western Reserve University, Psychology.
How many items can we store in visual working memory while simultaneously conducting a visual search? Previous research has proposed that only one visual working memory representation can be activated to influence attention directly, whereas other visual working memory representations are accessory items which have little influence on visual selection. However recent findings have suggested otherwise, specifically that two visual working memory representations can capture attention and interfere with concurrent visual search (Chen & Du, 2017). Across a series of studies, I investigated these findings further, and tested what the capacity of visual working memory is during visual search. The results from these studies suggest that multiple items held in visual working memory can capture attention and interfere with visual search. Specifically, I find that the capacity may be capped at two or three representations that can be simultaneously activated during search to guide attention, and that simplifying memoranda to a single feature does not increase capacity.
