The paper under consideration was one of his initial developments about the subject, and was recognized, and published in the Journal of Genetic Psychology in the year 1996. Summary This paper leads to the awareness of Attention Deficit Hyperactivity Disorder (later referred to as ADHD in this critique), primarily by means of discussing the various theories associated to ADHD and the possible adaptive function. The author agrees to the fact that no single theory succeeds at explaining the occurrence and presence of ADHD. Previously, however, it might have served as an adaptive function. The need for analyzing this issue comes from a clear pattern that shows distinctive behavioral changes amongst children, and some of them continue to show the same for longer periods of times. The research paper shows clear facts that approximately 5% of the school aged children are affected by ADHD and some half of these stabilize towards complete disorder in the later part of their ages. Identifying the need of this research by stating these facts and the need to understand this issue, the author then moves towards identifying the clinical features i.e. the symptoms of this issue leading towards the disorder. The author then refers to the biology of ADHD, where he describes the genetic reasoning of the issue.
