Extinction and recovery of the discriminative stimulus effects of nicotine (0.3 mg/kg) was investigated with a devalued food reinforcer (rats sated). Sixteen rats were trained in a counterbalanced one manipulandum (nose-poke) drug discrimination procedure with the roles of nicotine and saline counterbalanced as S[superscript D] and S[superscript…

Two experiments examined temporally based changes in the conditioned magazine-entries of rats when a target food pellet arrived at a fixed time before the termination of a conditioned stimulus. Both experiments found that increasing the rate of intertrial pellets systematically interfered with the rate of acquisition. When intertrial pellets were…

Reinstatement refers to the return of previously extinguished conditioned responses to test trials of a conditional stimulus (CS) when presentations of the unconditional stimulus (US) alone are given following extinction. Four experiments were conducted to determine whether reinstatement could be found in a conditioned suppression task with humans…

The basic principles of operant and classical conditioning are presented, and their applications for the in-service training of teachers are discussed. Certain classroom behaviors are analyzed and applied to the classic stimulus-response paradigm. Activities are generically classified as positive or negative reinforcers and these reinforcers, in…

Thirty five volunteer college women were divided into three groups to determine if heart rate could be conditioned instrumentally and lowered during exercise stress on the treadmill. The three groups were a) experimental group I, 15 subjects who received instrumental conditioning with visual feedback; b) instrumental group II, 9 subjects who…

Studies using fear-conditioning paradigms have found that anxiety patients are more conditionable than individuals without these disorders, but these effects have been demonstrated inconsistently. It is unclear whether these findings have etiological significance or whether enhanced conditionability is linked only to certain anxiety…

This paper was presented at the 1970 International Joint Conference sponsored by the American Geographical Society and the American Division of the World Academy of Art and Science held in New York City. The author postulates that education can be accountable to a changing world scene by offering students a relevant education so they may…

In a case of claustrophobia and in another with fears of flying, Japanese defense activities of the Karate type proved to be effective counter conditioners of anxiety. They were used in the former case in vivo and in the later case both in imagination and in vivo. (Author)

Designed to study implosive therapy with groups, this use of a behavioristic technique, which reduces unadaptive anxiety by emphasizing the presentation of the highly anxiety-evoking stimulus until the stimulus is no longer able to evoke anxiety, failed to produce a significant difference between control and therapy groups.

The purpose of this study was two-fold: (1) to determine whether alcoholics will show greater persistance in responding under punishment in a simple operant task as compared to nonalcoholics; and (2) with this task, under what conditions alcoholics will suppress their responses to the same extent as nonalcoholics. In the task, all subjects during…

A two-part study of 10 autistic children (mean age 10.5 years) was designed to assess the transfer of treatment gains across settings. (Author/SB)

The less-complex central nervous system of many invertebrates make them attractive for not only the molecular analysis of the associative learning and memory, but also in determining how neural circuits are modified by learning to generate changes in behavior. The nudibranch mollusk "Hermissenda crassicornis" is a preparation that has contributed…

Self-referred and court-referred clients were randomly assigned to one of three treatment groups, aversive counterconditioning, behavioral self-control training or a controlled drinking composite. All therapies were conducted by trained paraprofessionals and consisted of 10 weekly sessions. No significant differences among treatments were found.…
