About

In this line of research, the researchers are examining a basic science question regarding the working memory representations underlying visual search using a positive template (looking for a target) or a negative template (avoiding a distractor).

Full description

When finding a search target, receiving a target cue or distractor cue can increase search efficiency. Critically, in order to use these cues to help search performance, they must be maintained in working memory. The researchers are examining whether the working memory representations are of similar quality for a target cue (positive template) or distractor cue (negative template).
