Brief summary
In this line of research, the researchers having participants engage in task switching between tasks which require a positive (target) template, negative (distractor) template, or neutral (non-informative) template to the cognitive control factors associated with each template type during visual search. This is a basic science study.
Detailed description
The researchers will have participants engage in task switching between tasks which require a positive (target) template, negative (distractor) template, or neutral (non-informative) template to the cognitive control factors associated with each template type during visual search. Looking for impacts of task switching helps to identify the components of the cognitive control system that overlap between different types of attentional templates. This is a basic science study.
Interventions
Behavioral: Visual Search Information Type (target or distractor information) Participants will have information about targets, distractors, or neither in different trials of the intervention.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Button Press Reaction Time | One day (during 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 |
| Button Press Accuracy | One day (during testing) | Accuracy of responses to target item (% correct)- the researchers will measure whether the participants presses the correct button which corresponds to the target shape presented on the computer screen or the incorrect button |
| Eye Movements to Objects on Computer Screen | One day (during testing) | Proportion (% of total) of eye movements directed to potential targets or distractors, measured with an Eye Link II eye tracker |
