In honeybees, the proboscis extension response (PER) can be conditioned by associating an odor stimulus (CS) to a sucrose reward (US). Conditioned responses to the CS, which are acquired by most bees after a single CS-US pairing, disappear after repeated unrewarded presentations of the CS, a process called extinction. Extinction is usually thought…

Psychostimulant exposure has been shown to cause molecular and cellular changes in prefrontal cortex. It has been hypothesized that these drug-induced changes might affect the operation of prefrontal-limbic circuits, disrupting their normal role in controlling behavior and thereby leading to compulsive drug-seeking. To test this hypothesis, we…

We recently reported that fear extinction, a form of inhibitory learning, is selectively blocked by systemic administration of L-type voltage-gated calcium channel (LVGCC) antagonists, including nifedipine, in mice. We here replicate this finding and examine three reduced contingency effects after vehicle or nifedipine (40 mg/kg) administration.…

William James, the turn of the century psychologist, philospher, and educator, was avidly interested in the relationship between psychology and teaching. This paper considers operant conditioning, timing of reinforcers, and programmed instruction--touchstones of B.F. Skinner in the teaching/learning milieu. Of course, materials not just methods…

This paper describes a social-learning approach to counseling as it is developed at Valley View School for Boys, Illinois Department of Corrections. (Author/SM)

This paper presents a review of relevant literature on treatment approaches for the modification of smoking behavior, followed by an outline of an approach developed by the author to decrease his own rate of cigarette smoking. Studies are reviewed which have used various treatment methods: use of electric shock, satiation and/or use of cigarette…

Most histories of psychology and psychiatry attribute the first group psychotherapy to Joseph Pratt's 1905 class for tuberculosis patients. Pratt's actual treatment procedures are examined. They are shown to have consisted primarily of operant and social-learning techniques, aimed at increasing patient compliance with a demanding therapeutic…

The effectiveness of four operant procedures (differential reinforcement of incompatible behavior, omission training, overcorrection, and reinforcement withdrawal) in changing self injurious behavior (SIB) of 16 severely handicapped students was examined. Analysis of correlations between reduction in SIB and subject characteristics, adaptive…

A variety of psychotherapeutic methodologies has proliferated as a consequence of rapid growth in the need for mental health services. The effectiveness of many of these methods is questionable. Although each psychotherapeutic technique advances claims for its continued use based on clinical effectiveness, few offer adequate scientific evidence to…

The use of operant procedures was extended to decrease immediate echolalia and increase appropriate responding to questions of a 21-year-old autistic man. Multiple baseline designs demonstrated that echolalia was rapidly replaced with correct stimulus-specific responses. A variety of generalized improvements were observed in verbal responses to…

Comments on article by Ray E. Hosford in same issue. Presents several brief case accounts to indicate that behaviorists' explanations of techniques often do not do justice to their practice, suggesting advisability of doing as behaviorists do, not as they say. (Author/CJ)

The mothers and fathers of 11 preschool autistic children were taught operant procedures used in teaching speech to nonverbal children. At posttreatment, the children showed significant gains in pre-speech and speech skills as measured by a 21-step hierarchy of speech behaviors. (Author)

A 21-year-old woman who was totally blind, severely hearing impaired, functionally retarded, behaviorally resistive, self-stimulative, self-abusive, and who lacked basic communication skills, was taught to sit quietly and wait on command. (Author/PHR)

Predelinquent and delinquent youths were given behavior modification, social skills, and self-management training. The youths demonstrated a decrease in the number of problem behaviors exhibited at home and in school. The benefits of a self-management approach to juvenile offenders are discussed. (Author)

Evaluated the ability of propranolol hydrochloride to enhance results achieved with relaxation-biofeedback training. Results suggest that concomitant propranolol therapy (CPT) significantly enhanced the effectiveness of relaxation-biofeedback training. CPT also yielded larger reductions in analgesic use and greater improvements in quality-of-life…
