Motivation Effects During Cued Visual Search

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.

Study Overview

• Status: Enrolling by invitation
• Conditions: Healthy
• Intervention / Treatment: Behavioral: Motivation Manipulation

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	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)
