Task Switching Behavior Between Target Templates During Visual Search in Healthy Adults

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.

Study Overview

• Status: Completed
• Conditions: Healthy
• Intervention / Treatment: Behavioral: Experimental: Within-Subjects Attentional Information

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
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	One day (during testing)
Button Press Accuracy	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	One day (during testing)
