Twenty variables comprising the subtests of the Frostig, Illinois Test of Psycholinguistic Ability, Appalachia Preschool Test and the Peabody Picture Vocabulary Test raw score were factor analyzed by a principal component solution and an orthogonal rotation of the factor matrix. Although the different subtests were designed to measure specific abilities, these abilities could be masked by the presence of unknown underlying factors common to these tests. Eight factors were identified: vocabulary; reasoning; general reception; identifying body parts; general cognitive skills; visual perception; auditory memory; and verbal expression. The results of the factor analysis showed that, to some extent, the factors revealed certain abilities which discriminated between groups of children tested. The effectiveness of the Early Childhood Education (ECE) Program on at least a few factors was indicated. With the exception of the category of "verbal expression," in which the comparison group scored the highest, the ECE subjects had higher factor scores. A summary of the AEL Early Childhood Program is available as PS 004 889. (Author/NH)
