A previous patent (Thornton, 2001) by the inventor focused on the quantitative EEG (QEEG) correlates of successful cognition in normal subjects across a variety of cognitive measures. The present patent focuses on three critical cognitive skills (auditory memory, reading memory and problem solving) and examines a database which is comprised of normal subjects as well as subjects with head injuries, attention deficit disorders, learning disabilities, reading disabilities, math disabilities and unspecified clinical/learning problems.The QEEG correlates of success and failure were examined during the initial input stage of the task (i.e. listening to stories on a CD, reading text silently) and the immediate silent, eyes closed task of recall of the material. The problem solving task (Ravens matrices) QEEG correlates were examined during the administration of the task. The data was separated between children (ages 10-14) and adults (age greater than 14 years).
