Psychometric Testing and Cue Utilization During Cued Visual Search

Not Applicable

Terminated

• Conditions: Healthy
• Interventions: Behavioral: Behavioral Measurement

• Registration Number: NCT04964674
• Lead Sponsor: Lehigh University

Brief Summary

The experimenters will examine the relationship between utilization of positive (target cue) and negative (distractor cue) templates during a cued visual search task with performance on a set of measures related to executive functions associated with attentional control: shifting, updating, and inhibition.

Detailed Description

The experimenters will utilize the typical procedures for the cued attentional task, while also deploying the Miyake executive function analysis. Data will also include a working memory capacity measure.
