Concept learning is challenging in part because the meanings of many concepts depend on their relationships to other concepts. Learning these concepts in isolation can be difficult, but we present a model that discovers entire systems of related concepts. These systems can be viewed as simple theories that specify the concepts that exist in a…

Naming a picture of a dog primes the subsequent naming of a picture of a dog (repetition priming) and interferes with the subsequent naming of a picture of a cat (semantic interference). Behavioral studies suggest that these effects derive from persistent changes in the way that words are activated and selected for production, and some have…

This paper emphasizes the need to go beyond structural models of personality and intellect to develop sequential models of psychological process, particularly for such complex phenomena of prime concern to theory and application as learning, problem solving, and creativity. It is further argued that factor analysis, in a multitude of studies of…

Fear extinction is defined as a decline in conditioned fear responses (CRs) following nonreinforced exposure to a feared conditioned stimulus (CS). Behavioral evidence indicates that extinction is a form of inhibitory learning: Extinguished fear responses reappear with the passage of time (spontaneous recovery), a shift of context (renewal), and…

In this paper, we demonstrate nondeclarative sequence learning in mice using an animal analog of the human serial reaction time task (SRT) that uses a within-group comparison of behavior in response to a repeating sequence versus a random sequence. Ten female B6CBA mice performed eleven 96-trial sessions containing 24 repetitions of a 4-trial…

The primary thrust of this book is the presentation of two divergent models of man, the explicit and implicit philosophical assumptions which characterize each view, the conditions of learning compatible with each model, and the educational implications of each position. An introductory section considers the two models of man--the phenomenological…

Critical features of sound observational studies fall under three categories: the sampling framework; the theoretical model; and the statistical procedure. If the methodology for explanatory, rather than descriptive, observational studies can be applied within these categories, more consistent, convincing, useful explanations of educational…

It is difficult to account for the real and easily measured differences in verbal competence. Differential psychologists investigate basic traits from which observed behavior is thought to be generated, but if thinking is viewed as a problem in information handling, research will more profitably focus on the relationship between behavior in…

In a 1973 Smithsonian behavioral science project, observational methods were used to record school group behaviors during docent guided tours in the National Museum of History and Technology. The purpose of this exploratory study was to reveal the natural museum habitat and criterion behaviors of visiting fourth through sixth graders. Children's…

Performance becomes degraded when the human processing system undergoes the stress of processing overload. Information processing models are often used to predict how performance will be affected. Single channel models hypothesize that information will either be lost in the queue or processed with delay. Single capacity models predict that for a…

The case for behavior modification and some examples of its application in a variety of correctional settings are presented. The principles, techniques, and strategies utilized in programs designed to induce behavior change are largely determined by the model of causality to which one subscribes. A new approach to human behavior, which is the…
