Intellectual, Academic and Neuropsychological Performance Levels in Learning Disabled Adults

Abstract

Normative data are provided for intellectual, academic achievement and neuropsychological tests based on a sample of 100 learning disabled adults. The tests used included the Wechsler Adult Intelligence Scale, The Wide Range Achievement Test, a measure of reading comprehension and components of The Halstead-Reitan Neuropsychological Test Battery. The sample was characterized as being of dull normal intelligence with lower verbal than performance IQs. Scores on achievement tests were substantially below grade level. The average neuropsychological test profile formed a pattern characterized by intact nonverbal memory and problem solving ability, with mildly impaired levels of attentional, motor and speech discrimination skills. It was concluded that the cognitive profile found in learning disabled adults is not dissimilar from what is typically found in learning disabled children.
