Brief 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.

Detailed 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.

Primary

Measure	Time frame	Description
Button Press Reaction Time	During Testing (single day)	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
Button Press Accuracy	During Testing (single day)	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
Proactive EEG Activity	During Testing (single day)	Proactive (pre-search) Measures of EEG Theta Activity
Reactive EEG Activity	During Testing (single day)	Reactive (post-search) Measures of EEG Alpha Activity
