Developmental changes through adolescence in the spontaneous nomination of reference groups as a function of decision content.

The achievement of behavioral autonomy and psychological independence from the family is one of the foremost developmental tasks of the adolescent. This aspect of adolescent socialization is examined with regard to the developmental trends in the individual's nomination of socialization groups as competent referents in different areas of judgment. Eighty subjects, distributed equally between sex and among samples drawn from the fifth, seventh, ninth, and twelfth grades, were interviewed and allowed to nominate spontaneously reference groups of their own choosing for guidance in moral, informational, and social judgments. A significant relation was found between the nomination of a particular reference group and the nature of the decision to be made. The distribution of reference group nominations among the grade levels sampled differed significantly in the case of informational and social judgments. With increasing age during adolescence, peers seemed to be a more acceptable source of information in matters of social judgment than either parents or adults outside the family. Adults outside the family, however, exhibited a marked increase in acceptability as a reference group for judgments of an informational nature. Parents seemed to be the most acceptable referent across all grades for moral judgments. The findings are viewed particularly in relation to the results of studies which have examined developmental trends in simulated group conformity situations and susceptibility to cross-pressures. The possible reasons for the different developmental phenomena revealed by this study and by the conformity studies are discussed.
