Presents an experiment showing that naive trainers tend to allow factors such as task difficulty and competence of the trainee to affect the kind of reinforcement administered. Bibliography, tables, and graphs. (JB)

Examined the effects of a token economy on off-task behavior occurring concurrently with the reinforcement of target behavior. Results indicated that while the token economy maintained effectiveness in terms of increasing the frequency of target behaviors, the frequency of off-task or inappropriate behaviors also increased as the year progressed.…

In this study involving 20 four- and five-year-old children, the boys were more motivated by intermittent reinforcement from their fathers, while girls were more motivated by fathers' continuous reinforcement. (RL)

Behavioral analysis of reinforcers, adversities, and responses to adversities in videotapes of 14 college basketball games found that a team's favorable response to an adversity increased as the rate of reinforcement increased 3 minutes preceding the adversity and that calling time-outs was an effective intervention for reducing the opponent's…

The effects of a variable-ratio schedule of reinforcement on pedaling a stationary exercise bicycle were examined with 3 obese and 3 nonobese 11-year-old boys over a 12-week period. The intervention resulted in systematic increases in rate of exercise for all subjects. (Author/DB)

Discusses the nature of control, examining how organisms as control systems sense or monitor the variable being controlled when responding to environmental changes. Argues that learning is the development of control in an attempt to fit the two phenomena central to traditional learning theory--conditioning and reinforcement--into the broader…

This article reviews applications of the applied behavior analysis ideas of B. F. Skinner and others to persons with both mental retardation and emotional disturbance. The review examines implications of behavior analysis for operant conditioning and radical behaviorism, schedules of reinforcement, and emotion and mental illness. (DB)

A meta-analysis including 96 experimental studies considers the effects of reinforcement/reward on intrinsic motivation. Results indicate that reward does not decrease intrinsic motivation, although interaction effects must be examined. An analysis with five studies also indicates that reinforcement does not harm intrinsic motivation. (SLD)

This study examined how reinforcer rate, quality, delay, and response effort combined to influence the choices of six adolescents with emotional disturbance and learning difficulties and the feasibility of an assessment methodology based on matching theory for determining differential responsiveness to reinforcer and response dimensions. Results…

This study examined the effect of delayed reinforcement on mathematics performance by four fourth graders and the effect of programming stimuli common to reinforcement conditions on the maintenance of their performance. Participants exhibited similar levels of responding during intermittent and continuous reinforcement. Responding continued for a…

Eight crows were taught to discriminate overlapping pairs of visual stimuli (A+ B-, B+ C-, C+ D-, and D+ E-). For 4 birds, the stimuli were colored cards with a circle of the same color on the reverse side whose diameter decreased from A to E (ordered feedback group). These circles were made available for comparison to potentially help the crows…

Learning and memory are central topics in behavioral neuroscience, and inbred mice strains are widely investigated. However, operant conditioning techniques are not as extensively used in this field as they should be, given the effectiveness of the methodology of the experimental analysis of behavior. In the present study, male C57Bl/6 mice,…

The effects of rate of conditioned reinforcement on the resistance to change of operant behavior have not been examined. In addition, the effects of rate of conditioned reinforcement on the rate of observing have not been adequately examined. In two experiments, a multiple schedule of observing-response procedures was used to examine the effects…

Two experiments examined whether postsample signals of reinforcer probability or magnitude affected the accuracy of delayed matching to sample in pigeons. On each trial, red or green choice responses that matched red or green stimuli seen shortly before a variable retention interval were reinforced with wheat access. In Experiment 1, the…
