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.

Outcome Measures

Primary Outcomes (3)

• 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)

• 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)
