"The conditionability of the eyeblink response using a photocell method with human infants was explored... The data indicate the feasibility of studying such conditioning in young infants. (Author)

Using an objective measure of attention obtained during a baseline period, assesses in two studies the effects of attention on operant learning among 240 infants 14 weeks of age who were rewarded for kicking with a pattern of lights and tones. (RH)

Studies dealing with toilet training of severely/profoundly retarded persons are reviewed since the systematic operant approach of N. Azrin and R. Foxx in 1971. Replications are said to be few in number and equivocal in results, although modifications with retarded and nonretarded populations have produced informative and innovative approaches.…

Two normal and two mentally retarded children were trained to earn pennies by pressing a key according to a multiple variable-interval extinction schedule of reinforcement. Retarded children differed from normal children by producing more positive than negative discriminative stimuli. (Author/DB)

An integrated study of Shine's actualized and pure single-subject behavior functions can produce more information than studying only one function. After summarizing the mathematics behind Shine's viewpoint, an ordinary regression analysis approach to the actualized behavior function is integrated with a time-series analysis approach to the pure…

The philosophies underlying the learning and structural theories used in psychology are described in this article. It is argued that a dialectical view provides some ways to breach the chasm between learning theory and the study of human development. (Author/DB)

Results of this study indicate that sample group of unskilled laborers were more productive working under a schedule of continuous reinforcement than under a varied schedule, despite higher average earnings during the latter program. (RW)

Investigates factors that have effects on conditioning. Tests nine mice with three types of reinforcement: (1) primary-need positive reinforcement; (2) secondary-need positive reinforcement; and (3) secondary-need negative reinforcement. Measures the effectiveness of the reinforcements by both rate of response and response strength. Discusses the…

Literature is reviewed documenting the relationship between implementation of communication intervention and decreases in excess behavior in persons with severe disabilities. Operant conditioning and pragmatics are discussed in terms of their joint application to excess behavior, and a list of possible pragmatic intents of excess behavior is…

Four young adults with moderate mental retardation were taught to include "please" as part of requests, and four environmental stimuli present during training were assessed. Results indicated that presence of a single stimulus or pair of stimuli increased the probability of the "please" response, whereas presence of other…

This study evaluated use of the interpolation of reinforcement effect, which combines intermittent (INT) and continuous reinforcement (CRF) schedules, with four young children with autism using a free-operant preparation. Results suggest that responding may be less resistant to extinction following interpolated CRF reinforcement than following INT…

Sensitivity to reinforcement contingencies was examined in six individuals with mental retardation using a concurrent operants procedure in the context of a computer game. Results included individual differences in sensitivity and differential sensitivity to rate and magnitude variation. Results suggest that comprehensive assessments of potential…
