Parsing Items into Separate Categories: Developmental Change in Infant Categorization.
Younger, Barbara A.; Fearing, Dru D.
Child Development, v70 n2 p291-303 Mar-Apr 1999
Three experiments used a familiarization/novelty or a habituation/dishabituation procedure to examine developmental change in infants' tendency to parse exemplars into separate categories. Results indicated that 10-month olds appeared to form differentiated categories, whereas 4- and 7-month olds formed a single category to include the range of items presented during familiarization. An a priori stimulus-preference explanation was ruled out. (Author/KB)
