Evaluated with 12 children (9- to 25-months-old) were the efficacy and reliability of auditory stimulus-response control training and assessment procedures. (Author/LS)

A series of three experiments was conducted with three severely retarded children to investigate the vocalization-producing potential of two antecedent conditions: adult talk (commonly cited antecedent) and adult silence. (Author/CL)

Results indicated no significant differences between conditioning procedures in regard to obtained MRLs (minimum response levels) number of stimulus presentations required to establish MRL (discounting conditioning trials), and number of false-positive responses observed during control trial for 60 premature infants at one or two years of age.…

A language development program for a 6-year-old boy with limited language development combined an operant approach in the foster home, where both parents were speech clinicians, and daily 3-hour therapy sessions at a university speech and hearing clinic. (KW)

Response and reinforcement features of operant discrimination paradigms used in audiometric assessment were investigated with normal 17-month-old children. Findings indicated more responses prior to onset of habituation when response tasks involved complex central processing skills and a twofold increase in number of subject responses when…

In a two part article the author first discusses the importance of fluency, rate, breathstream management, prosody, and self-confidence to the replacement of stuttering with normal speech; and second outlines specific clinical procedures for achieving these goals with adult and adolescent stutterers.
