Certain materials - crayons, paints, clay - stimulate different levels of behavior. Whenever materials are relevant to the attainment of certain behavioral objectives they seem to serve as the center of the activity in terms of establishing and maintaining the desired behaviors. (CK)

Presented is a series of studies in which the efficacy of applying operant conditioning methodologies to the problem of stuttering was examined. One requirement was that the designed therapeutic programs utilize only verbal contingent stimuli (reinforcers and punishers) in the traditional therapeutic setting (client and therapist seated together…

Because training teachers to collect observational data and to use operant techniques has frequently been found to be prohibitively time-consuming, the author attempted to develop simpler, more efficient training procedures. This report presents the results of a study in which these procedures were implemented. Teachers followed a three step…

Arbitrarily applicable derived relational responding has been argued by relational frame theorists to be a form of operant behavior. The present study examined this idea with 4 female participants, ages 4 to 5 years old, who could not perform a series of problem-solving tasks involving arbitrary more than and less than relations. In a combined…

Operant conditioning of the H-reflex, the electrical analog of the spinal stretch reflex, is a simple model of skill acquisition and involves plasticity in the spinal cord. Previous work showed that the cerebellum is essential for down-conditioning the H-reflex. This study asks whether the cerebellum is also essential for maintaining…

A program for secondary remedial reading instruction was developed to use operant conditioning techniques with the following major objectives: (1) to train the student to decode words systematically, (2) to develop the student's verbal repertoire, (3) to improve reading comprehension, and (4) to shape scholarly attitudes and behavior. Pupils were…

The effectiveness of positive and negative evaluative comments for children's learning was assessed in a two-choice discrimination task. Results indicate that negative comments after incorrect responses greatly facilitated learning while positive comments after correct responses had little effect. To explain the findings, a naturalistic analysis…

The results of a group of studies, the objective of which was to clarify the conditions that account for the effectiveness of verbal approbation, are reported. Among the most significant findings were: (1) that the reinforcement properties of verbal approval are susceptible to distortion, misinterpretation or enhancement and must be applied in a…

A series of five experiments revealed a striking point-for-point correspondence between the effects of a reinforcer in escape conditioning and the effects of competition cessation in competitive performance. (Author/MP)

Results of an experiment with 6-month-old infants showed that response-independent auditory-visual reinforcement can elicit learned responses and that action-consequence learning in infants may consist of a combination of elicitation and conditioning. (Author/JMB)

A procedure is described that uses operant conditioning principles to shape earphone wearing in block-dropping play audiometry. Vibrotactile stimulation is used as the first step in testing difficult-to-test children. (Author/CL)

A total of 30 infants with an average age of 83.4 days were trained for one l8-minute, two nine-minute, or three six-minute sessions separated by 24-hour intervals in order to investigate long-term retention of operant foot kicking acquired in the mobile conjugative reinforcement paradigm.
