distracters or only distracters, with no target. The job of the participant is to determine whether the target is present as quickly and accurately as possible. This visual search experiment is used to examine reaction times involving visual based attention. Observations taken from the analysis of these results can help to determine how we perceive our environment. 2. This visual search experiment consisted of 80 different trials. The number of distracters varied; there were slides with 4, 16, 32

Attention Deficit Hyperactivity Disorder: Influence on Adolescent Development Attention Deficit Hyperactivity Disorder: Influence on Adolescent Development Attention Deficit Hyperactivity Disorder, abbreviated by ADHD, is a common behavioral disorder that affects roughly 10% of adolescent children.

children are starting to be misdiagnosed with attention deficit/hyperactivity disorder due to certain characteristics that children are exhibiting and this is exacerbated by: behaviors that are developmentally appropriate, cultural differences between home and school, and the lack of knowledge of the symptoms and disorder that is ADHD.
