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…

Two groups of 10 male rats were trained to nose poke for food pellets at four alternatives that provided differing rates of pellet delivery on aperiodic schedules. After a fixed number of pellets had been delivered, 5, 10 or 20 in different conditions of the experiment, a 10-s blackout occurred, and the locations of the differing rates of pellet…

The philosophies underlying the learning and structural theories used in psychology are described in this article. It is argued that a dialectical view provides some ways to breach the chasm between learning theory and the study of human development. (Author/DB)

Examining the norm formation process in terms of internalization versus conditioning, this study concludes that Sherif's 1935 model of norm formation (internalization) is questionable, suggesting, rather, that with the internalization of group norms there appears to be a tendency for individual judgments to diverge when returned to individual…

Today, the term 'behavior therapy' has no clear denotation. Those who adhere to the more delimited meanings of behavior therapy tend to disregard significant nonbehavioral therapeutic development. They also overlook convincing data demonstrating that in adult humans, conditioning is produced through cognitive mediation. Adoption of a more…

Argues that a better understanding of developmental processes is provided by three types of operant research -- laboratory behavioral descriptions, descriptions of naturalistic behavior-environment interdependencies, and predictive naturalistic studies. The usefulness of these processes are examined in light of the goals of life span developmental…

Based on the assumption that inferential statistics can make the operant conditioner more sensitive to possible significant relationships, regressions models were developed to test the statistical significance between slopes and Y intercepts of the experimental and control group subjects. These results were then compared to the traditional operant…

Reading comprehension, indicated by motor behavior and multiple-choice picture selection called for in written instructions, was taught to an autistic child (12 years old). (Author/PT)

This paper presents a number of inferential statistical models that may aid the operant investigator in presenting his data. (Author/RK)

Extensive review of the literature suggests that modeling procedures are effective means of changing behavior, not only with one client but with a group. School counselors, in particular, need to be aware of the negative effect of various grouping policies, and should expose behavior problem clients to socially acceptable models. Followed by…
