Body part identification in 1- to 4-year-old children.

The purpose of this study was to examine the sequence in which body parts are learned and can be identified by very young children. The 101 children tested were divided into four age groups: 1-year-olds, 2-year-olds, 3-year-olds, and 4-year-olds. The children were requested to point to 20 body parts on a doll. Analysis of the results indicated significant differences in the ability to identify body parts by age and sex. The greatest increase in scores occurred between the ages of 1 and 2 years, with girls achieving a slightly higher score in each age group. The percentage of subjects at each age who identified different body parts is presented, indicating the sequence in which body parts are learned.
