Abstract
This study replicated the 1984 work of Miller who reported a normal mean Verbal IQ of profoundly deaf students. To 27 profoundly deaf students the WISC--R Verbal Scale was administered using one of three signed language systems. The means do not support Miller's findings and raise some doubt about the mediating effects of language systems among profoundly deaf students.
