Brief summary

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).

Detailed 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).

Interventions

BEHAVIORALVisual Search Cue Type

Participants receive a target color cue (positive), a distractor color cue (negative), or a neutral non-informative cue prior to visual search.

Measure	Time frame	Description
Button Press Reaction Time	Day 1 (single day of testing)	Speed to respond correctly to the target- after participant finds the target shape on a computer screen, they press a button to indicate what shape they see
Button Press Accuracy	Day 1 (single day of testing)	Accuracy of responses to target item-measure whether the participants presses the correct button which corresponds to the target shape presented on the computer screen or the incorrect button
Working Memory Report Quality	Day 1 (single day of testing)	Accuracy of computer clicks on a set of colors to indicate memory of cue presented
