Healthy Adults 18 to 39 Years Old Needed for a Research Study

Why are we doing this research?

The purpose of this research study is to understand brain development in adults with Attention Deficit Disorder (ADD) and Attention Deficit Hyperactivity Disorder (ADHD) compared to typical adults who do not have ADD, ADHD or other behavioral conditions.

The focus is on learning more about the brain’s abilities to control coordinated hand and finger movements.

Who can participate?

Those eligible for participation are healthy adults, between the ages of 18 and 39 years old, who:


  • Are right-handed 
  • Have no significant neurological, developmental or psychiatric diagnoses



  • Do not have a close relative (parent, brother, sister) with ADD or ADHD.



  • Healthy Adults

What will happen in the study?

 The study involves 2 visits. The following is a list of procedures that may take place during the study:


  • An initial screening
  • Demographic questionnaires
  • A procedure called a Transcranial Magnetic Stimulation (TMS) which looks at brain development and motor skills
  • Computer games
A detailed list of procedures will be provided to anyone interested in knowing more about this study.


What are the good things that can happen from this research?

You may receive no direct benefit from participating in this study. The greatest benefit is that you may be contributing to research that helps other people. Research studies are essential in finding new and improved treatments and diagnostic tools.

Will I get all the facts about the study?

Participants who are interested in participating will be given a consent form that thoroughly explains all of the details of the study. The form covers all of the procedures, the risks, the benefits, the pay, who to contact with questions or concerns and more. A member of the study staff will review the consent form with you and will be sure that all of your questions are answered. Study procedures will not begin until the participant has signed the consent form.

What are the bad things that can happen from this research?

There are limited risks associated with the use of TMS. Based on previous studies involving both children and adults exposed to TMS, there may be mild and temporary side effects such as scalp discomfort, hand weakness and headaches.

A detailed list of possible side effects will be provided to those who are interested in knowing more about this study.

Will you/your child be paid to be in this research study?

Participants will receive $20 for the first hour and $10 for every additional hour of their participation.
