Clinical Trial 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.

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.
