Eight autistic, language impaired, and non-language impaired children (six-eight years old) were compared on a dichotic listening task to determine hemispheric lateralization. Language impaired Ss exhibited a left ear bias for language material (indicating right hemisphere lateralization for language), while the autistic and non language impaired…

A follow-up study of handedness in 34 autistic persons (mean age 8 years) supported the idea that there are many factors other than brain damage, hemispheric functioning, age, and follow-up interval that contribute to hand lateralization. (CL)

Utilizing computerized brain tomography, left-right morphologic asymmetries of the parieto-occipital region were judged in 16 autistic patients (7-27 years old), 44 mentally retarded patients, and 100 miscellaneous neurological patients. (Author)
