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.
