Psychometric Testing: Cued vs. Learned Suppression

Study Overview
=================
Brief Summary
-----------------
In this line of research, the researchers are examining whether performance on a cued attentional suppression (ignoring) task is related to performance on a learned attentional suppression task. In addition, these measures are related to the capacity of working memory and every day inattentive traits.

Detailed Description
-----------------
This is a behavioral study. The researchers will measures performance on multiple tasks. 1) a cued attentional suppression task, where participants are told the color of the item they are supposed to ignore on each trial. 2) a learned attentional suppression task, where participants learn over experience that a particular color is not the target. 3) a visual working memory capacity measurement 4) an inattentive trait report task, where participants report their experiences of inattention during their daily lives.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Attention and Working Memory Tests<br>All participants will complete a series of behavioral tasks, including cued visual search with positive (target color), negative (distractor color) and neutral (baseline) cues, learned visual search with a repeated salient distractor color, a visual working memory capacity task, and a daily life inattentive traits questionnaire (self-report). Single Arm. | Behavioral: Behavioral Measurement and self-report<br>* Measurements of behavioral performance and self-report<br>|
