Nonverbal learning disability, school behavior, and dyslexia.

The aims of the study were to investigate whether children showing a low nonverbal/high verbal (LNV) WISC-R profile are more likely to exhibit behaviors conducive to school failure than children with a low verbal/high nonverbal (LV) profile, and to examine the relationships among these behaviors, the LNV/LV profiles, and reading ability. The 65 subjects included 27 LNV and 38 LV children, aged 5 to 11 years. Results confirmed earlier findings (Badian 1986) that LNV children are perceived by their teachers as significantly poorer than LV children in many behaviors associated with school success. There was a dichotomy, however, between LNV good and poor readers. All LNV subjects displayed problems in organizational skills, but those who were dyslexic were poorer in social behavior (e.g., acceptance of criticism and peer relationships) than either LNV good readers or LV good or poor readers. It was concluded that children with a low nonverbal/high verbal profile and a probable right hemisphere dysfunction, who appear to be dyslexic in the early school years, are at high risk for both social behavior problems and school failure, and that these children are a more high-risk group than poor readers with a low verbal/high nonverbal profile.
