An empirically developed infant and preschool reinforcement survey was completed by 35 parents and 21 children. Test-retest coefficients were computed on these data after a one-week interval. The development of the survey, as well as its usefulness for school psychologists, is described. Survey is appended. (Author)

Suggests that the use of the operant conditioning paradigm, as it has been applied to infant social, vocal behavior, fails to take into account the social nature of human infants over and above the rigid theoretical rationale of the Paradigm. (MP)

Assesses the present status of behaviorism by dividing this study into an evaluation of Behaviorism 1, based explicitly on Pavlov's conception of conditioned-response learning, and Behaviorism 11, single-handedly launched and almost completely dominanted by Professor B. F. Skinner. (Author/RK)

Reviews three response rate measures (in a baseline measurement, immediately after acquisition, and at a long-term retention test) of infant memory that are used in experiments involving infants' conditioned kicking. Compares these measures to a new measure, the fraction of kicking rate remaining after the retention interval. Explains the…

Three experiments examined whether newborns are sensitive to an operant-conditioning task involving unprepared relation between a response and a stimuli. Found that newborns tested under the High-Amplitude Sucking procedure were involved in an operant-learning situation, in that an increase in sucking rates could be obtained after an auditory…

Classical conditioning is responsible for students' positive and negative feelings, whether directed toward subject matter, peers, teachers, or education in general. This article explains how educators can use classical conditioning principles (such as reinforcement, extinction, and paired stimuli) to create an anxiety-free learning environment.…

This response to a paper by Guess and Carr (EC 602 212) on stereotypy and self-injurious behavior in the disabled focuses on (1) potentially misleading statements that may discourage practitioners from operant approaches to stereotypy and self-injury, and (2) strengths and weaknesses of the model compared to existing operant models.

This article discusses problems inherent in the analysis of automatically reinforced behaviors, which are behaviors that are maintained by operant mechanisms independent of the social environment. Four classes of treatment that are compatible with automatic reinforcement are reviewed, including manipulations of establishing operations, sensory…

Five adolescents with autism, 5 control participants, and 4 child controls received rewards for varying their sequences of responses while playing a computer game. In preceding and following phases, rewards were provided at approximately the same rate but were independent of variability. When reinforced, variability increased significantly in all…

Darwinian selection by consequences was instantiated in a computational model that consisted of a repertoire of behaviors undergoing selection, reproduction, and mutation over many generations. The model in effect created a digital organism that emitted behavior continuously. The behavior of this digital organism was studied in three series of…

We investigated the benefits of using a virtual laboratory, Sniffy Lite CD-ROM (Alloway, Wilson, Graham, & Krames, 2000), as a supplemental teaching tool to present schedules of reinforcement in operant conditioning. Our results suggest that using the virtual laboratory significantly enhanced understanding. Students who used the virtual laboratory…

In two experiments, 40 undergraduate students were trained on conditional discrimination tasks (matching to sample) involving 1 of 4 types of instructional histories: (a) true instructions followed by false instructions; (b) false instructions followed by true instructions; (c) true instructions followed by true instructions, with a change of…

The present study utilized a fear potentiated startle paradigm to examine amygdala function in individuals with autism spectrum disorder. Two competing hypotheses regarding amygdala dysfunction in autism have been proposed: (1) The amygdala is under-responsive, in which case it would be predicted that, in a fear potentiated startle experiment,…
