Presented is the Marshalltown Behavioral Prescription Guide for social development which consists of incremental behavioral objectives and strategies to aid parents in the prescriptive teaching of handicapped and culturally deprived infants and preschool children. The guide is intended for use prior to a weekly home visit, which results in a weekly prescription left with the parents. The program is described as involving a 6 hour orientation course and monthly meetings for parents to allow them to introduce the management procedures and chart the child's progress. It is hoped that parents will eventually be able to use the program materials directly. Each of the 117 profile items are presented individually in terms of profile number, behavioral definition, cue/s, measurement criteria, materials needed, and behavioral objectives and strategies. Sample prescription forms are also included. The following are examples of profile items: smiles and vocalizes to mirror, gives kisses, carries or hugs doll, uses spoon appropriately, separates from mother readily, takes turns, feeds self, apologizes, relates dreams, and demonstrates dialing of own phone number.
