Loading of the G-factor in human figure drawing

This study reports the results of a bifactorial analysis of the criteria of the Human Figure Drawing Test, based on the original Goodenough system. This analysis was designed to assess the loading of the general factor of intelligence for that test. 541 children (52.9% boys, 47.1% girls; ages 5-10 years) attending preschool through Grade 4 in public and private schools were studied. Principal component analysis with oblimin rotation identified four components which were not highly correlated, making it possible to conduct a bifactorial analysis. The results were interpreted as showing the predominance of a single general factor, so the existence of a latent variable capable of explaining most of the variance (56.84%) between the items seems likely.
