Selective Attention Mechanisms Applied in Attention Deficit Hyperactivity Disorder

The attention deficit is the major factor of Attention Deficit Hyperactivity Disorder (ADHD). This paper aims to demonstrate difficulties in selective attention of subjects with ADHD as compared to subjects without ADHD, attempting to verify which mechanisms of selective attention are more affected in subjects with ADHD. For this purpose, we evaluated selective attention in subjects with and without ADHD (152 without and 31 with ADHD), in a population of 183 subjects. The general results show that the subjects with ADHD present lower selective attention skills than the subjects without ADHD, specifically as far as rightness, errors, concentration and processed elements are concerned.
