Action-outcome contingencies can be learnt either by active trial-and-error, or vicariously, by observing the outcomes of actions performed by others. The extant literature is ambiguous as to which of these modes of learning is more effective, as controlled comparisons of operant and observational learning are rare. Here, we contrasted human…

We investigated the involvement of PKA and PKC signaling in a negatively reinforced operant learning paradigm in "Aplysia", learning that food is inedible (LFI). In vivo injection of PKA or PKC inhibitors blocked long-term LFI memory formation. Moreover, a persistent phase of PKA activity, although not PKC activity, was necessary for long-term…

A series of five experiments revealed a striking point-for-point correspondence between the effects of a reinforcer in escape conditioning and the effects of competition cessation in competitive performance. (Author/MP)

The author of this article presents his own explanation on the two types of conditioning--respondent and operant. He states that when withdrawal of a negative reinforcer is the contingency that increases the strength of the operant behavior, the stimulus will have a negative emotional response to the experimental chamber. However, when a positive…

Two punishment procedures were compared to determine their effectiveness in reducing rates of noncompliance in a class of 11 educable mentally retarded elementary school students. (Author/DLS)

Contends that, although the operant approach to psychology is based on objective empirical observations, much of psychology is filled with subjective, interpretive terminology. Argues that such terminology produces confusion over the definitions of basic operant concepts. Suggests a solution that defines the concepts of positive and negative…

Psychology students frequently have misconceptions of basic concepts in operant conditioning. Prior classroom observations revealed that most students defined positive reinforcement as reward and equated negative reinforcement and punishment. Students also labeled positive reinforcement as rewarding good behavior and negative reinforcement as…

Michael (1975) reviewed efforts to classify reinforcing events in terms of whether stimuli are added (positive reinforcement) or removed (negative reinforcement). He concluded that distinctions in these terms are confusing and ambiguous. Of necessity, adding a stimulus requires its previous absence and removing a stimulus its previous presence.…

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)
