Summary The draw‐a‐man test was performed on 348 children within 10 days of their third birthday, and the results were tested by Fisher's z ‐test to see if there is any significant difference according to the birth order. The score for the later‐born children were found to be significantly superior to those of the first‐born. For the second‐born children. the test ratings have been correlated with the age difference which separates them from the older sibling. The average score was higher in those with less than 31/2 years' spacing. As the age difference increases, the average score approaches that of the first‐born. The results seem to indicate that in some field of the child's activity and its progress, the influence of an older sibling is remarkable and the influence is more effective if the age difference is small.
