title: Cognitive evaluations of young adults by means of human figure drawings: an empirical investigation of two methods.
abstract: This study evaluated Buck's (1948) House-Tree-Person and Goodenough and Harris's (1963) Draw-A-Person scoring systems for assessing the cognitive abilities of young adults. IQ scores based on these scoring systems and, in the case of the H-T-P, using only the first person drawn, were correlated with WAIS-R Verbal, Performance, and Full Scale IQs. Both figure scoring systems correlated significantly with WAIS-R Performance and Full Scale IQs, but were underestimates of WAIS-R IQs. H-T-P scoring of the house, tree, and second person drawn then was added to the scoring of the first person drawn to see whether such additions would enhance validity. They did not. Results are discussed in terms of characteristics of the scoring systems' standardization samples and limitations of these systems.
