Motor planning, attention deficit hyperactivity disorder, response time, reaching movement
Abstract
Individuals with attention deficit hyperactivity disorder (ADHD) experience motor deficiencies during their daily routine and difficulties in motor planning. Internal processes of motor planning influence the response time of starting a reaching movement following different planning intervals. In this preliminary study, we compared motion onset patterns following different planning intervals of eight participants diagnosed with ADHD with those of healthy participants from a previous experiment. The minimum response time in participants with ADHD was shorter than that of the healthy participants, possibly indicating less effective maintenance of the motor plan in working memory.
