Selected findings from the initial 5 years of a longitudinal study of political learning in young children are examined with regard to their theoretical implications. To a limited extent, traditional social learning theory accounted for children’s recognition of political symbols, awareness of public policy issues, and knowledge of the electoral-political party process. Also a limited success was the effort to construct a three-level six-stage framework of political understanding consistent with cognitive developmental theory in the Piagetian or Kohlbergian tradition. A more satisfactory, comprehensive theory of political learning must be able to deal with both incremental and structural change in knowledge. Contemporary information processing theories may prove useful in this regard.
