Selectivity and strategy in early search

Abstract

Early information-processing strategies were examined in a study of very young children's search for hidden objects. Sixteen younger children (mean age: 1 year; 11 months) and sixteen older children (mean age: 2;6) received search problems in which observational and/or verbal information about an object's location was provided. The question of primary interest was how they would respond when given two conflicting sources of information, which differed in modality (observational vs verbal) and in currentness. Both younger and older children showed some use of an appropriate strategy of relying on the more current information, although they did not follow it consistently. Children also showed preferential use of observational over verbal information and response biases favoring the middle location. Age differences were found in children's use of verbal information, in the degree to which they benefitted from practice, and in response biases. These results suggested a distinction between two aspects of the development of search: the acquisition of new search skills and the establishment of appropriate priorities among skills already in the child's repertoire.
