Structure of Ordinal Scales of Psychological Development in Infancy

Abstract
Intercorrelations among Uzgiris and Hunt's scales for 2 samples of infants were subjected to cluster analysis and factor analysis. The results of these procedures were similar for both samples, 3 clusters from the first analysis resembling 3 factors from the second. The findings were also consistent with Uzgiris and Hunt's observations on the structure of the scales.
