Clinical Trial 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.

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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)
Primary	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)
Primary	Eye Movements to Objects on Computer Screen	Proportion (% of total) of eye movements directed to potential targets or distractors, measured with an Eye Link II eye tracker	One day (during testing)
