This research compared two methods used to investigate the knowledge of internal body parts by children ages 4 to 9 years. Subjects were 50 Italian children: 18 preschoolers, 21 first graders, and 11 second or third graders. Children performed two tasks, a Drawing Task in which they drew on the outline of a human figure all the body parts they could recall and named them; and a Recognition Task in which children selected among three pictures of the inside of the human body and named all the body parts they could recognize. Children's performance was scored by counting the number of body parts drawn and labeled, with paired structures counted as a single response in both tasks. Results indicated that the Recognition Task elicited a greater number of body parts than the Drawing Task. Older children performed better than younger ones on both tasks, and boys did better than girls on both tasks. The most commonly listed body parts were heart, brain, bones, blood, and muscles.
