Infants' Exploratory Behavior During an Object Search Task Which Requires Crawling Around a Barrier
Pages 4

Tremendous developmental changes take place during the first year of life. As motor abilities rapidly mature (eg., sitting upright, crawling, walking), infants show increased attention to relevant environmental properties, first objects and then ground surfaces (Gibson, 1988). These changes are accompanied by increasing cognitive abilities (Bertenthal, Campos, & Barrett, 1984). The purpose of this study was to examine the relationship between development of crawling and performance on a modified Piagetian object search task (crawling around a large barrier as in Lockman, 1984). We expected infants with greater locomotor experience to use more efficient search strategies and to be more successful at retrieving the hidden objects.
