Abstract: This study was aimed to examine the relation between crawling experience andthe development of detour behavior in infants aged 8--10--month. One hundred andsixty--five infants (79 Precrawlers and 86 crawlers) were tested in the lab withstandardized prcoedures. The results indicated: (a) Crawling status had significant maineffect on the infants' detour task performance; this main effect was still significantwhen the infants' age was controlled statistically; Infants with crawling experience gotmuch higher scores than precrawlers, which indicated that crawling experience hadpositive effect on the infants' detour behavior development. (b) There was significantpositive correlation between the duration of crawling and the score on detour task.With the infants' age being controlled statishcally, this positive correlation was stillsignificant which provided further evidence for crawling experience as a facilitator ofthe infants detour behavior development. (c) In the 8--month--old group, crawlingexperience faCilitated the infants' detour behavior development significantly; in the 9and 10month--old groups, while crawlers showed the tendency of performing betterthan precrawlers, there was no significant difference in the development of detourbehavior between the crawlers and the precrawlers.

Key words: crawling experience, infants, detour behavior
