Working Memory Quality of Attentional Templates

May 16, 2023 updated by: Lehigh University
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).

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Button Press Reaction Time
Time Frame: 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
Day 1 (single day of testing)
Button Press Accuracy
Time Frame: 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
Day 1 (single day of testing)
Working Memory Report Quality
Time Frame: Day 1 (single day of testing)
Accuracy of computer clicks on a set of colors to indicate memory of cue presented
Day 1 (single day of testing)
