The Wechsler Adult Intelligence Scale-Revised (WAIS-R) and the Cognitive Test for the Blind were used to compare verbal and nonverbal abstraction ability of adults who became blind before age 2 or after age 5 (when expressive language would have been developed). No significant differences were found, but variability of scores on the WAIS-R suggests that educational experiences may influence performance on standardized intelligence measures. (DB)
