Abstract

Aspects of intellectual function were investigated in a school age sample of Fragile X individuals employing the Wechsler Intelligence Scale for Children — Revised (WISC-R). Results indicated that the general ability of the sample was substantially below normaltive average. More important, this result was forced by the significantly lower performances of males compated with females. With the exception of one skill, females had significantly higher WISC-R sub-test scores than males. The exception was for Digit Span indicating that females had a specific weakness in short-term memory. There was a nonsignificant negative correlation between X fragility and IQ for males. There was no correlation between fragility and IQ for females. There was a nonsignificant negative correlation between age and IQ for females. There was no correlation between age and IQ for males. These results are discussed in terms of previous findings and their implications for education of Fragile X individuals.
