Task Switching Between Target Templates During Visual Search in Healthy Adults

Not Applicable

• Conditions: Healthy

• Registration Number: NCT05709743
• Lead Sponsor: Lehigh University

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.

Primary Outcome Measures

Name	Time	Method
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
