Purchase probability as a function of interpurchase time was examined through comparison of findings from laboratory experiments on reinforcement schedules and from marketing investigations of consumers' interpurchase time. Panel data, based on a sample of 80 consumers who purchased nine supermarket food products during 16 weeks, were used. For…

This guide to behavior modification provides teachers and others who work with children with some practical suggestions to reinforce productive classroom behavior. A description of common elementary classroom problems, the principles and ethical considerations in the use of behavior modification, suggestions for establishing a classroom climate…

This article presents an interpretation of autoshaping, and positive and negative automaintenance, based on a neural-network model. The model makes no distinction between operant and respondent learning mechanisms, and takes into account knowledge of hippocampal and dopaminergic systems. Four simulations were run, each one using an "A-B-A" design…

A theory of attending and reinforcement in conditional discriminations (Nevin, Davison, & Shahan, 2005) is extended to working memory in delayed matching to sample by adding terms for disruption of attending during the retention interval. Like its predecessor, the theory assumes that reinforcers and disruptors affect the independent probabilities…

Three experiments with rats examined reacquisition of an operant response after either extinction or a response-elimination procedure that included occasional reinforced responses during extinction. In each experiment, reacquisition was slower when response elimination had included occasional reinforced responses, although the effect was…

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…

Sequential theory's memory model of learning has been successfully applied in response contingent instrumental conditioning experiments (Capaldi, 1966, 1967, 1994; Capaldi & Miller, 2003). However, it has not been systematically tested in nonresponse contingent Pavlovian conditioning experiments. The present experiments attempted to determine if…

This study asked whether the concurrent reinforcement of behavioral variability facilitates learning to emit a difficult target response. Sixty students repeatedly pressed sequences of keys, with an originally infrequently occurring target sequence consistently being followed by positive feedback. Three conditions differed in the feedback given to…

Provides the counselor a current survey of behavior therapy procedures as well as information concerning their applicability and validity. Reviews procedures based on operant learning principles, classical learning principles, and social psychological principles. Examples and case presentations are included. (Author/RC)

The main argument being presented in this paper is that instructional designers and educational researchers need to shift their attention from performance to interest. Educational digital games have to aim at building lasting interest in real world applications. The main hypothesis advocated in this paper is that the use of rewards in educational…

Recognizing that punishment for aggression often is noneffective or inadvertently reinforces the aggressive act, the authors discuss an alternative approach and provide an explanation of the exchange theory of aggression. Three classroom experiments, operated with children chosen as the most severe behavior problems in a local school system, are…

A description of the Social Exchange Laboratory's work with autistic children is presented. The laboratory's philosophy of the exchange theory of autism, seen as a set of habitual response patterns maintained and intensified by exchanges which are inadvertantly structured by others in the child's environment, is set forth with characteristics,…

Based upon the author's doctoral dissertation (University of Minnesota, 1967).

The study sought to identify effective procedures for facilitating initial imitative vocal behavior in mentally retarded children, thus accelerating the initial stages of language acquisition. Three groups of Down syndrome children ages 6 months to 4 years (N=15) served as subjects in an examination of the relative effectiveness of three…
