title: Content analysis and intratest performance profiles on the Columbia and the TONI.
abstract: This research note presents the results of a content analysis of the Columbia Mental Maturity Scale and the Test of Nonverbal Intelligence (TONI). We also compared the intratest performance of a selected sample of language-impaired (LI) and MA-matched normal language children on these two tests. These analyses are an extension of Johnston's (1982) report on the Leiter. The content analysis revealed differences in the nature of perceptual and conceptual items on the Columbia and the TONI. Consistent with Johnston's findings, the intratest comparisons revealed no significant group differences. LI and normal-language children performed significantly better on the perceptual-type items than the conceptual-type items. The predominance of perceptual items was particularly evident in the TONI.
