ResumoAbstract Operant conditioning techniques were applied to the verbal behavior of three speech deficient children. Subjects A and B having no intelligible speech and Subject C having very little. Using candy and a puppet with a 13-yr-old boy (A), it was possible to condition vocalization rate. Using social reinforcement with a 6-yr-old boy (B), it was possible to extinguish animal-like sounds, to condition vocalization rate, and to shape a small vocabulary of syllables, but not to gain discriminative control over word emission. Using varied reinforcers, e.g., candy, praise, repetitions other own responses, and hand clapping with a 13-yr-old girl (C), it was possible to condition rate of verbalization, to establish appropriate mimicking, and to establish naming of five pictures. The results were consistent with the findings of Salzinger et al. (1965) and with those of Kerr et al. (1965).
