This article demonstrated that equations derived from Herrnstein's matching law can make quantitative predictions for many of the effects David Premack has studied on the relative nature of reinforcement. (Author/RK)

The interest in this study was to determine the factor structure of the independent variables in a brain-damaged population and to assess its predictive value for complex test variables independent of those variables that determine the factor set. (Author/RK)

The present study assessed whether a relatively current change in one's physical state was associated with a change in body image and attitude about self-control. It also addressed the question of whether obese persons learned to limit the number of cues that served as stimuli for food intake. (Author/RK)

The purpose of the present research was to replicate O'Leary, et al.'s previous findings (EJ 100 528) and to test the hypothesis that the correlation between Rotter's Locus of Control scale and the Taylor Manifest Anxiety scale was moderated by neuroticism and negativism toward self. (Author/RK)

This study tested the prediction that children in a tempting situation would resist longer when they had interaction with an adult before exposure to the temptation situation. (Author)

In this article the author attempted to understand the relationship between John B. Watson's personal conflicts with the fundamentalist religious culture in which he was reared and his development of a particular psychological paradigm and experimental practice, the theory and research of behaviorism. (Author/RK)

This article, exploring the degree of our freedom to act, was based on some intriguing hypotheses relating behavior to brain function. (Author/RK)

The present study used videotaped horse races to test Kelley's attribution theory of the way people perceive the causes of behavior. (Editor)

The relationship between group cohesiveness and performance was investigated using data from a field setting. (Editor)

Three important deficiencies of learning hierarchy validation studies - inadequate scope, inappropriate validation technique and lack of replicative data - were identified, and substantially resolved in the construction and replicate validation of a comprehensive network of graphical interpretation skills.

Earlier reports of the pain of putting hand and forearm in circulating ice water were recomputed to study how subjects scale that pain and to find appropriate measures of its reduction under hypnotic analgesia. (Editor)

This experiment was designed to further investigate how noun imagery as a task variable may supplement the operation of an experimental-frequency mechanism (Ekstrand, Wallace, and Underwood, 1966) in verbal-discrimination learning. (Author)
