Loading of the G-factor in human figure drawing.

Area of Science:

• Psychometrics
• Developmental Psychology
• Educational Psychology

Background:

• The Human Figure Drawing Test (HFDT) is a widely used tool in developmental and educational psychology.
• Its underlying structure and relationship to general intelligence require further psychometric investigation.
• The original Goodenough system provides a basis for analyzing drawing components.

Purpose of the Study:

• To conduct a bifactorial analysis of the Human Figure Drawing Test criteria.
• To assess the loading of a general intelligence factor within the HFDT.
• To determine the latent variable structure explaining item variance in children's drawings.

Main Methods:

• Bifactorial analysis of HFDT criteria.
• Principal component analysis with oblimin rotation.
• Study sample: 541 children (ages 5-10 years).

Main Results:

• Four principal components were identified, with low intercorrelations.
• Bifactorial analysis indicated the predominance of a single general factor.
• This general factor explained a significant portion of the variance (56.84%) among test items.

Conclusions:

• The findings support the existence of a latent variable, likely representing general intelligence, within the Human Figure Drawing Test.
• The HFDT, when analyzed with bifactorial methods, appears to measure a substantial general cognitive ability.
• Further research can refine the understanding of HFDT's psychometric properties and its utility in assessing intelligence.
