Preschool children''s evaluation and integration of visual and auditory information in speech perception was compared with that of adults. Subjects identified speech events, which consisted of synthetic speech syllables ranging from /ba/ to /da/ combined, with a videotaped /ba/, /da/ or no articulation. Both variables influenced the identification judgements for both groups of subjects. Results were used to test current views of the development of perceptual categorization and speech perception. Tests of quantitative models indicated that both preschool children and adults had available continuous and independent sources of information. Results were well described by a fuzzy logical model of perception, which assumes that the perceiver integrates continuous and independent sources of information and determines the relative goodness of match to prototype definitions in memory. The only developmental differences was less of an influence of the visual source of information for children relative to adults. One explanation is that the children simply attended to the visual source. A 2nd experiment eliminated the attentional explanation by showing identical results when the children also were required to indicate whether or not the speaker''s mouth was moving.
