Effects of modeling and contingent praise on infant's motor response topographies were experimentally analyzed. Three male 10-month-olds showed systematic increases in targeted training and probe response topographies after introduction of the modeling and praise treatment procedure. Thus generalized imitation with infants was demonstrated. (RH)

An adaptation of incidental teaching procedures was used to teach individually defined language responses to four language-delayed children (4-8 years old). Data showed that frequency of each targeted response increased only during incidental teaching, with most targeted responses produced spontaneously; and the teachers correctly implemented the…

Analyzed effects of modeling and contingent praise on infant imitation of three responses: motor-with-toy, motor-without-toy, or vocal. Found a systematic increase in the percentages of training and probe models matched by the three 12- to 14-month-olds following introduction of model-and-praise treatment conditions. Nonmatching responses did not…

Four children (ages 4-6) with autism were taught to use gestures in combination with oral communication. Intervention was introduced successively across three response categories that contained gestures representative of attention-directing/getting, affective, and descriptive behavior. Results indicated that all participants acquired this skill…

Describes a study of three infants whose parents presented vocal models for the infants to imitate. Parents presented vocal models both with and without social praise. Infants showed systematic increases in matching after praise was introduced. Nonmatching vocalizations did not increase with introduction of praise. Findings demonstrate generalized…
