About this study
EEG Measures during Visual Search Task. In this line of research, the researchers having participants receive a positive (target) template cue, negative (distractor) template cue, or neutral (non-informative) template cue. Note: This is a re-analysis of previously collected data.
Read the detailed description
When finding a search target, receiving a target cue or distractor cue can increase search efficiency compared to a neutral cue. The researchers are examining the neural basis of visual search when participants receive a positive (target) cue, negative (distractor) cue, or neutral (baseline) cue. Note: This is a re-analysis of previously collected data.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Attentional Cue TypeBehavioural
Positive cue (target), negative cue (distractor), or neutral cue (baseline)
| Study group | Role | What they receive |
|---|---|---|
| Within-Subjects Attentional Information | Experimental | All Participants receive all levels of the attentional cue (target, distractor, or neutral cue). Receives: Behavioral: Attentional 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: During Testing (single day)
Button Press Accuracy
Accuracy of responses to target item- we will measure whether the participants presses the correct button which corresponds to the target shape presented on the computer screen or the incorrect button
Measured: During Testing (single day)
Proactive EEG Activity
Proactive (pre-search) Measures of EEG Theta Activity
Measured: During Testing (single day)
Reactive EEG Activity
Reactive (post-search) Measures of EEG Alpha Activity
Measured: During Testing (single day)

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 5 Oct 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
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: During Testing (single day)). The study lists 4 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 5 Oct 2023.
