Generalization of stimulus control in different situations and with novel adults occurred with those children who were trained by contingent reinforcement, but not with those trained by both contingent and noncontingent reinforcement. This research was submitted as part of the author's dissertation. (MH)

Fifty participants were exposed to a simple discrimination-training procedure during which six S+ functions were established for six arbitrary stimuli, and S- functions were established for a further six stimuli. Following this training, each participant was exposed to one of five conditions. In the S+ condition, participants were exposed to a…

Four male and five female Negro children (ranging in age from 5 to 9 years) served in an experimental comparison of the discriminative control exerted by sex and race aspects of other children. A baseline was established in which color photoslides of a Negro girl and a Caucasian boy differentially controlled responding on two push buttons.…

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…

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

Among the findings were that the treatment procedure produced immediate and substantial suppression effects on the self-injurious behavior, which generalized to the nontraining environment and endured over an eight-month interval. (Author/DLS)

In earlier studies with rats, the effectiveness of the auditory element of a tone--light discriminative stimulus was enhanced when the conditioned incentive value of the compound was negative rather than positive. The present experiment systematically replicated these results in pigeons trained to press a treadle in the presence of a tone--light…

This paper develops a stimulus selection theory, based on an extensive review of previous research, which gives weight to context change or stimulus generalization decrement. The theory assumes no special compounding or configurational process, and accounts for the learning of successive discriminations without the addition of any special process.…

Two autistic boys, ages 6 and 10 years, whose imitative responding was functionally inaccurate and whose performance generalized poorly, were trained to imitate accurately using a reinforcement-extinction strategy. (DLS)

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…

Two environmental learning conditions based on generative linguistics were tested to determine whether they could induce in children (in grades 1-3) the acquisition of the rules of metaphors and the subsequent generation of metaphors based on the acquired rules. The first modeling condition (MC-1) emphasized the verbal-interaction effect: the…

Stimulus discrimination is a standard subject in undergraduate courses presenting basic principles of learning, and a particularly interesting aspect of discrimination is the peak shift phenomenon. Peak shift occurs in generalization tests following intradimensional discrimination training as a displacement of peak responding away from the S+ (a…

While few would disagree that token economies are effective in bringing certain positive and negative target behaviors under contingent control, the recent past has witnessed increased concern over choice of targets as well as back-ups, voluntary versus involuntary client participation, as well as the effectiveness of such programs in meeting…

One hundred twenty-eight preschool boys were subjects in a 4x2x2 factorial design to investigate the change in reinforcer efficacy as a function of prior stimulus exposure. The factors were: (1) amount of repetition, 5, 25, 45, or 65; (2) reinforcer, good or bell; and (3) satiator, good or bell. Two additional groups were run as control groups to…
