Working Memory Quality of Attentional Templates

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).

About this study

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).

Treatment and study plan

Visual Search Cue Type

Behavioral

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

Primary outcomes

  1. 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

  2. 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

  3. 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
