Stokes, Osnes, and Guevremont's (1987) implicit definition of correspondence classes is fundamentally procedural. A contingency-space analysis, on the other hand, is independent of specific procedures and focuses attention on problems inherent in some procedural definitions. It addresses the issue of distinguishing specific instances from classes.…

The article proposes a sequential alternating treatments design requiring that two treatments be initially implemented in a random or counterbalanced fashion followed by a sequential change in one or both treatments across settings, subjects, or tasks. This design is appropriate when it is not feasible to obtain a traditional baseline condition.…

A detailed hypothesis of the acquisition and maintenance of self-stimulatory behavior is offered, proposing that such behaviors are operant responses whose reinforcers are automatically produced perceptual consequences. Related concepts are discussed, and support for the hypothesis from the areas of sensory reinforcement and sensory deprivation is…

Effectiveness in the future must take into account cost-benefit ratios, social validity assessments, and the need for…

Serious delinquent behavior may be part of a disabling and durable condition that consists of multiple antisocial and dysfunctional behaviors, often runs in families, and eludes effective short-term treatment. The socializing influence of long-term supportive family treatment is discussed as a therapeutic alternative. (Author/JW)
