Clinical Trial 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).


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).

Outcome

Type Measure Description Time frame Safety issue
Primary Button Press Reaction Time 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 Day 1 (single day of testing)
Primary Button Press Accuracy 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 Day 1 (single day of testing)
Primary Working Memory Report Quality Accuracy of computer clicks on a set of colors to indicate memory of cue presented Day 1 (single day of testing)
