The Relationship of Intelligence, Visual Problems and Neurological Organization to Reading-Learning Disabilities.
Califf, James I.
A study was conducted to collect information on the origins of reading and learning disabilities and on the characteristics of learning disabled children. Data were collected from case histories and evaluation and follow-up reports for 372 learning disabled subjects, aged 6 to 22 years. Characteristics of the subjects were similar to those of dyslexic, hyperkinetic, minimally brain damaged, and perceptually handicapped children. The evidence collected indicated the following conclusions: (1) the general origin of reading disabilities appears to be parental blood incompatibilities complicated by various prenatal difficulties; (2) the effect of these problems is neurological disorganization, which caused 80% of the subjects to have losses of a year or more in reading and spelling levels; (3) 98% of the children had average or better intelligence; (4) school retention causes further losses in reading achievement; (5) gains made from remedial programs are retained; and (6) it is hard to determine the effect of neurological disorganization on reading achievement because poor teaching and the frustration of failure can also depress reading achievement.
