Three-dimensional construction tests for children aged five and six years.

The constructional praxis ability of 69 normal 5 and 6 year olds was studied to validate established norms, to gain normative data for the Gesell Block Test and the Benton and Fogel Test of Constructional Praxis, and to identify a developmental continuum. No significant difference was found between scores obtained by the two age groups; however, a difference significant at the less than .05 level was found between scores of five-year-old boys and girls. The results suggest that these tests measure a continuum of development and that with revisions they may be useful to provide additional information about development of constructional praxis ability in a larger sample of normal and brain-damaged children.
