Study Overview
Brief Summary
In this line of research, we are examining whether motivation increases the utilization of target (positive) or distractor (negative) color cues to improve visual attention performance.
Detailed Description
When finding a search target, receiving a target cue or distractor cue can increase search efficiency. We are examining whether we can improve people's use of the cues to aid visual search performance if we increase their motivation through reward or time pressure.

Outcomes
Primary Outcomes
Button Press Reaction Time
Time Frame: 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
Time Frame: 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
Secondary Outcomes
No secondary outcomes reported
