Previous research has suggested that the availability of high-preference stimuli may override the reinforcing efficacy of concurrently available low-preference stimuli under relatively low schedule requirements (e.g., fixed-ratio 1 schedule). It is unknown if similar effects would be obtained under higher schedule requirements. Thus, the current…

Investigated simultaneous occurrence of emergent stimulus-response relations (functional equivalence) and stimulus-stimulus relations (stimulus equivalence). Trained 4- and 5-year olds to emit specified responses to pairs of stimuli in one setting (original training) and to emit other responses to one member of each pair in another setting…

Pigeons were trained to respond to stimuli from a continuous stimulus dimension (tonal frequency) with response values from continuous response dimension. Both the number of points of correspondence and problem difficulty were varied. Following training, subjects were tested with stimulus values intermediate to those trained. During these test…

Describes the rationale underlying as well as the major features of a computer-interactive APL program IRIS, the objective of which is to obtain an individual's simple ordering of a set of stimuli in as few paired comparison preference judgments as possible. (Author/RC)

Children and adults were trained and tested on formation of novel simple discriminations and conditional stimulus relations. Subjects who formed these sets were trained and tested on formation of stimulus equivalence classes. A modest majority of children matched directly paired stimuli; a few matched indirectly paired stimuli. All normal adults…

The personality characteristics which were found to be related to stimulus seeking seem to follow from the basic premise that the stimulus seeker has a stronger than average need to seek out and approach situations, activities, and ideas which are novel, changing, complex, surprising, or more intense.

One of a series of original statements on a central concept, principle, theory, or problem in the social sciences, this module presents a definition and some illustrations of paired associate (PA) learning and a summary of the procedures used in PA learning. Many of the important research findings on PA learning are briefly recounted and a basic…

Trained preschoolers and adults on three sets of successive discriminations with stimuli labeled A, B, and R. Tested for derived stimulus-response relations and stimulus-stimulus relations. Adults displayed class-consistent B-R and A-B performances over all conditions. Children's display of class-consistent B-R performance varied by training…

Infants in four age groups--three, six, nine and twelve months--were exposed to an experimental procedure designed to assess the extent to which such subjects were capable of discriminating between different orientations of the same form, and the extent to which they were capable of recognizing the identity between different orientations of the…
