Psychometric Testing: Cued vs. Learned Suppression

Not Applicable

Completed

• Conditions: Healthy
• Interventions: Behavioral: Behavioral Measurement and self-report

• Registration Number: NCT06074523
• Lead Sponsor: Lehigh University

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.

Arm && Interventions

Group	Intervention	Description
Attention and Working Memory Tests	Behavioral Measurement and self-report	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.

Primary Outcome Measures

Name	Time	Method
Button Press Reaction Time	1 day	Reaction times on visual search task with positive, negative, and neutral cues
Learned Suppression Task	1 day	Reaction times on visual search task no salient distractor and learned salient distractor
Visual Working Memory Capacity	1 day	Visual Working Memory Capacity- Change Localization; Estimate of number of items maintained in working memory
Inattentive Traits Subscale of Adult Attention Deficit Hyperactivity Disorder (ADHD) Self Report Scale	1 day	Adult Attention Deficit Hyperactivity Disorder (ADHD) Self Report Scale (used on healthy adults), Inattentive Traits subscale. Higher values indicate more ADHD-like inattentive trait symptoms (0-45).
