Dimensional Dominance Hierarchies and the Matching of Letters and Words

Abstract

Abstract. Dimensional dominance was assessed by having kindergarten children make similarities judgments about geometric figures varying in form, color, and size. Children who were classified as form dominant performed better than children who were not form dominant when given a test of letter matching ability in Experiment 1 and in repeated tests of word matching ability in Experiment 2. Data from the retest in Experiment 2 supported the hypothesis that dimensional dominance progresses from color dominance to form dominance, and then to mixed responding.
