Abstract

Given the symptoms of autism, it can be challenging to assess the cognitive functioning of individuals with this disorder. A previous study has shown that the Test of Nonverbal Intelligence (TONI) holds promise for use with individuals with autism (Edelson, Schubert, & Edelson, 1998). That study determined which variables predicted testability on the TONI as well as TONI scores. The purpose of the present study was to determine whether our findings from this original study could be replicated in an independent sample of individuals with autism from Taiwan. Similar results were found regarding mean TONI scores and the variables that best predicted TONI scores across the two studies despite differences in verbal ability between the two samples. The implications of these results were discussed regarding the utility of the TONI in assessing the intelligence of individuals with autism.
