This paper reports a study of cerebral dominance in 42 preschool and kindergarten children. In order to tap left hemisphere functioning, a story of approximately 650 words and 77 specific plot details was composed. Children listened to the 7 minute story and were asked to repeat it. Responses were taped. Tangram pieces were used to assess right hemisphere functioning. Twelve puzzles were presented to each child, using from two to six tangram pieces. In addition, records of handedness and eye dominance were obtained. Each child was tested in two sessions on different days. All subjects required prompts on the story task. Similarly, prompting was used with the Tangram puzzles when the child seemed unable to proceed. Results of individual profile analyses indicated that 50% of the children had major discrepancies in hemispheric functioning. Children between the ages of five and six appeared to have clear differences in "learning styles" or "strengths." The relationship of the findings to reading failure is briefly suggested. (Author/RH)
