The document describes a process-oriented strategy for assessing children with atypical motor development. The Ordinal Scales of Psychological Development in Infancy by I. Uzgiris and J. Hunt are used as the content base. The intervention program focuses on teaching parents techniques for enhancing the child's functioning in sensorimotor, motor, and communication functioning. Unique features of the Uzgiris-Hunt instrument are noted, as is its conceptual basis. Adaptations of the instrument are described, including modifying the task or materials and carrying out the child's direction. Four levels of organization in sensorimotor intelligence are described and examples of adaptations for physically handicapped children are given: undifferentiated actions (systematic repetition of simple schemes); differentiated actions (intentional use of schemes within familiar contexts); regulation by differentiated feedback (discovery of new means to ends by new combination and modification of familiar schemes); and anticipation of regulations (problem solving through nonovert adaptation of multicomponent actions). Implications for parent instruction include a feedback model in which the child's developmental level determines the complexity of parental input, and the parent's input changes as the child's abilities change.
