Psychometric Testing: Cued vs. Learned Suppression

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.

About this study

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.

  3. Visual Working Memory Capacity

    Time frame: 1 day

    Visual Working Memory Capacity- Change Localization; Estimate of number of items maintained in working memory

  4. Inattentive Traits Subscale of Adult Attention Deficit Hyperactivity Disorder (ADHD) Self Report Scale

    Time frame: 1 day
