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.

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Attentional Cue Type | Behavioral | Positive cue (target), negative cue (distractor), or neutral cue (baseline) |
|
| Measure | Description | Time Frame |
|---|---|---|
| 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) |
| 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) |
| Proactive EEG Activity | Proactive (pre-search) Measures of EEG Theta Activity | During Testing (single day) |
| Reactive EEG Activity | Reactive (post-search) Measures of EEG Alpha Activity | During Testing (single day) |
