The influence of frequency of occurrence of a visual stimulus on encoding processes is investigated, to discover what mechanisms allow cognitive processes to modify perceptual processes. Six experiments are described and the results are discussed. (MH)

Two children (ages 10 and 12) with severe mental retardation were trained to make the same response when presented with 2 initially unrelated stimuli and then trained to make a new response when presented with 1 of those stimuli. Children were then assessed on their response to the second stimulus. Results of the tests for the emergent…

This study explored whether an identity-matching-based stimulus equivalence procedure could be used to teach vowel and consonant stimulus classes to two adolescent females with moderate mental retardation. Both participants acquired five-member classes of vowel and consonant stimuli, which subsequently generalized to vocal classification and to…

The initial purpose of the present study was to replicate procedures for teaching preschool children to recruit attention at appropriate times by having an experimenter signal the availability and unavailability of attention (i.e., arrange a multiple schedule involving reinforcement and extinction; Tiger & Hanley, 2004). Following the development…

Working from a rationale derived from cognitive learning theory, this study was designed to investigate the extent to which the formation and modifiability of first impressions may be affected by the perceiver's tendency to associate the stimulus person with some other individual. Fifty subjects rated their initial attractions toward male and…

Two groups of retarded adolescents were presented sets of multiple verbal directions (imperative sentences). One group was exposed to pictures illustrating the objects and action of each direction in addition to the verbal directions. Subjects were required to carry out performances demanded by the directions. The direction-following behavior of…

This paper reviewed (a) conceptualization, (b) research, and (c) theories of inductive reasoning and, in turn, proposed both a behaviorally-oriented definition and matching process model. The overall conclusion was that, in spite of the pervasiveness and importance of induction as a knowledge generation process, research and theoretical activities…

With the advent of multi-screen capability in multi-media communication centers, it is possible to control the visual learning environment in a number of interesting ways. The basic assumption implicit in the concept of the multiple-image presentation is that it increases learning. A study tested the effect on learning of single- and…

Examines the effects of different-intensity unconditioned stimuli as well as generalization to related and unrelated test words. Its results indicate that semantic generalization is not a consequence of mediated generalization as traditionally conceived. (Editor/RK)

A discussion of several types of formal neurons, many of whose functions are modifiable by their own input stimuli. The language of finite automata is used to mathematicize the problem of adaptation sufficiently to remove some ambiguities of Brindley's approach. (Author)

Spontaneous and model-induced production of a valuational style of inquiry was studied in 128 third-grade children. (Authors)

Study conducted to investigate attention span in relation to various schedules or regimes of reinforcement. (Author/MB)

Analyses indicated that varying the range of test stimuli changes the discriminability of the stimuli within that range, even though the physical differences among these stimuli remain constant. (Author)
