There has been a resurgence of interest in the use of projective doll play techniques, partly arising out of the recognition of the sophistication of young children's play. This review considers a number of recent projective doll play innovations and evaluates the utility of these techniques for investigating young children's moral development, attachment beyond infancy, and for predicting behaviour problems. In addition, the use of these techniques with high-risk and clinical populations is described and a discussion of factors influencing the quality of projective play responses is presented.
