简要总结
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.
详细描述
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.

研究组 & 干预措施
Within-Subjects Attentional Information
Within-Subjects, all participants receive all interventions
干预措施: Experimental: Within-Subjects Attentional Information (Behavioral)
结局指标
主要结局
Button Press Accuracy
时间窗: 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
时间窗: One day (during testing)
Proportion (% of total) of eye movements directed to potential targets or distractors, measured with an Eye Link II eye tracker
Button Press Reaction Time
时间窗: 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
