Body-Part Size Estimation in Children

Abstract

30 children in Grades 1, 3, and 5 estimated the sizes of 8 personal body parts, 8 experimenter's body parts, and 4 nonbody objects. Errors of estimation were consistent across subjects and similar to those reported for adults. Hand length was estimated most accurately, and head width, forearm length, and lips estimated least accurately, on both self and experimenter. Non-body objects were estimated most accurately, followed by experimenter's body parts, and then personal body parts. No sex or age differences were found.
