Sequential Order and Plasticity in Early Psychological Development.
Hunt, J. McVicker
Four issues related to psychological development are discussed. These issues concern: (1) the criteria by which the separate levels, or structures, or stages of psychological development are to be identified; (2) the principle by means of which these configurations are to be ordered; (3) the nature of the transitions taking place between developmental landmarks, stages, or states; and (4) the nature of the processes within the individual and between the individual and his circumstances which account for the transformations from one stage or state to another. Criteria used in producing six ordinal scales of sensorimotor development were: (1) ease of elicitation, (2) observer agreement, and (3) theoretical meaningfulness. Sequential organization of behavioral landmarks must come from longitudinal studies of infants examined repeatedly during their development; inevitable sequentiality calls for longitudinal studies of infants developing under as wide a variety of cultures and conditions as feasible. Behavioral landmarks imply any of several forms of transformation. The characteristics of the transformations between successive levels or states are implicit in the nature of the differences between the characteristics of the observable behavioral landmarks of successive levels. Cross-sectional data derived from children developing under three differing sets of rearing conditions and data from two longitudinal studies are provided, which indicate great variation in the ages at which infants and young children achieve the various levels of object construction which are correlated with their environmental circumstances.
