Infant Gesell scores vs. cognitive skills at age 12 years.
In an earlier study, it was found that infant performance on the Gesell correlated better with performance on nonverbal than verbal cognitive skills up to the age of 5 years. Recently, the same 26 male middle-class Ss, now 12 years old, were retested with the WISC-R, WRAT, and PPVT. Performance on the Gesell was found to relate significantly to WISC-R Performance IQ and to a lesser extent to PPVT IQ, but did not relate to WISC-R Verbal IQ nor to performance on the WRAT. The results suggest that the Gesell has a better predictive validity for nonverbal than verbal cognitive skills.
