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.
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.

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
Time frame: During Testing (single day)
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
Time frame: During Testing (single day)
Proactive EEG Activity
Proactive (pre-search) Measures of EEG Theta Activity
Time frame: During Testing (single day)
Reactive EEG Activity
Reactive (post-search) Measures of EEG Alpha Activity
Time frame: During Testing (single day)
