Clinical Trial Summary

EEG Measures during Visual Search Task. In this line of research, the researchers having participants receive a positive (target) template cue, negative (distractor) template cue, or neutral (non-informative) template cue. Note: This is a re-analysis of previously collected data.

Description:

When finding a search target, receiving a target cue or distractor cue can increase search efficiency compared to a neutral cue. The researchers are examining the neural basis of visual search when participants receive a positive (target) cue, negative (distractor) cue, or neutral (baseline) cue. Note: This is a re-analysis of previously collected data.

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	During Testing (single day)
Primary	Button Press Accuracy	Accuracy of responses to target item- we will measure whether the participants presses the correct button which corresponds to the target shape presented on the computer screen or the incorrect button	During Testing (single day)
Primary	Proactive EEG Activity	Proactive (pre-search) Measures of EEG Theta Activity	During Testing (single day)
Primary	Reactive EEG Activity	Reactive (post-search) Measures of EEG Alpha Activity	During Testing (single day)
