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.

About this study

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.

Treatment and study plan

Experimental: Within-Subjects Attentional Information

Behavioral

Visual Search Information Type (target or distractor information) Participants will have information about targets, distractors, or neither in different trials of the intervention.

Primary outcomes

  1. Button Press Reaction Time

    Time frame: 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

  2. Button Press Accuracy

    Time frame: 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
