dc.description.abstract Previous research has identified motor deficits within the ADHD population, and indicates that these individuals are at an increased risk for difficulties relating to their motor development. The present study, which utilized discriminant function analysis, was unable to document areas of motor impairment for individuals diagnosed with ADHD. Specifically, no evidence of motor impairment was identified on tasks of motor coordination, fine motor dexterity, motor speed and grip strength, which measures the integrity of the motor system at the basic output level. Interestingly, results identified that individuals with ADHD were more proficient in their motor abilities than the normative population. Two mitigating factors were controlled for in this study and were found to impact performance on motor tasks. First, higher level thinking skills such as verbal comprehension, attention control, cognitive sequencing, working memory and executive functions appear to be more responsible for documented performance deficits than an underlying motor deficit. Secondly, the high prevalence of comorbid psychiatric and medical disorders, inherent to the ADHD population, appears to negatively impact performance on motor tasks. In general, individuals with only a diagnosis of ADHD consistently outperformed individuals who had been diagnosed with ADHD and comorbid disorders.This study also examined the sensory and subcortical abilities of individuals with ADHD. Results indicate that these children are similar to their same age peers in their visual perception, visual acuity, auditory discrimination and tactile perception. Finally, this study was unable to identify evidence of impairment in the subcortical abilities of ADHD individuals. In fact, individuals with only a diagnosis of ADHD outperformed the control group across a majority of tasks assessing subcortical abilities. Comorbidity also appears to negatively impact performance on sensory and subcortical tasks, especially for individuals with comorbid medical conditions. Overall, results from this study impact the field of research which previously identified motor performance deficits in the ADHD population. Further research is needed to examine the sensory and motor abilities of ADHD individuals to understand the performance abilities of individuals with ADHD. en_US
