Description: Nurses are encouraged to consider children's levels of understanding when communicating about physiological phenomena such as body contents and functioning. The problem is that these levels are not known. Application of Piaget's levels of cognitive development and levels of development of the concept of physical causality are not appropriate for determining children's levels of understanding physiological causality.

The purpose of this study was to determine what schoolage children at various ages know about nutrition and digestive processes, and to identify the types of logic that schoolagers typically use to explain such phenomena. A stratified random sample of 70 six to twelve year old children (n = 10 per age group) were individually interviewed. Each child filled in a blank body outline with all the body parts he/she could think of, and was asked a series of questions about nutrition and digestive processes.

Digestive system parts were the most frequently drawn body parts by all schoolagers, particularly the stomach, liver, intestines and esophagus. Accuracy in size, shape and location of body parts varied among and between children in each age group. The variety of children's responses to questions about nutrition and digestive processes were very similar across age groups.

Analysis of the types of logic that schoolagers use to explain physiological phenomena revealed that over-simplification, unilateral functioning, transformation, and contiguity were the most frequently used. Older children elaborated on their responses while younger children answered "I don't know" when unsure, rather than guessed. For each age group, the percentage of total responses that included each type of logic was similar, i.e. children of all ages used each type of logic at approximately the same frequency. One cannot differentiate children of various ages by the types of logic that they use.

Findings suggest that individual assessment of children's knowledge is imperative, and that blank body outlines are valuable nursing assessment tools. Explanations to schoolagers need not be held to a concrete or animistic level of logic for schoolagers. Assumed levels or stages of cognitive development according to age are not useful indicators of children's levels of understanding of physiological phenomena.
