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.
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.

This study is a simple behavioral intervention, examining performance on a computer-based cognitive psychology task. There were no expected risks beyond typical daily computer use, which may include headache from looking at at a computer screen or boredom. No serious adverse events were expected. Research assistants monitored for unanticipated adverse effects.
