About this study
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).
Read the 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 participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Visual Search Cue TypeBehavioural
Participants receive a target color cue (positive), a distractor color cue (negative), or a neutral non-informative cue prior to visual search.
| Study group | Role | What they receive |
|---|---|---|
| Within-subjects Cue Type | Experimental | Participants receive a target color cue (positive), a distractor color cue (negative), or a neutral non-informative cue prior to visual search. Receives: Behavioral: Visual Search Cue Type |
What is being measured
The primary outcome is the main question the study is designed to answer.
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
Measured: Day 1 (single day of testing)
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
Measured: Day 1 (single day of testing)
Working Memory Report Quality
Accuracy of computer clicks on a set of colors to indicate memory of cue presented
Measured: Day 1 (single day of testing)

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Button Press Reaction Time (time frame: Day 1 (single day of testing)). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 May 2023.
