In a study of 949 elementary students, mixed support was found for four theoretical positions concerning the role of childhood in career development. For Ginzberg's theory, support was found for his observation that interests play the major role in both the selection and rejection of careers throughout the period of childhood. For Roe's theory, the authors found evidence that family configuration influenced occupational choice/no choice. From Havighurst's theory, support was found for the idea that identification with a parent's work is particularly strong among younger children. A number of aspects of each of the theories failed to be confirmed.
