EFFECTS OF WARNING STIMULI FOR REINFORCER WITHDRAWAL AND TASK ONSET ON SELF-INJURY

Results of a functional analysis of self-injurious behavior (SIB) in a child with autism showed that her SIB was maintained by access to preferred objects and escape or avoidance of task demands. Extinction and noncontingent reinforcement treatments were supplemented by presenting a statement combined with a picture cue at 30-s intervals indicating that a preferred object would be removed or a task would be presented. Warning stimuli in combination with extinction and noncontingent reinforcement reduced SIB to acceptable levels. SIB rates remained comparatively high in a control condition consisting of a 2-min delay to onset of reinforcer removal or task demands.     

Application of The Assimilation Model in The Context of Family Therapy: A Case Study

In this case study the aim was to apply the APES (Assimilation of Problematic Experiences Scale) model to the analysis of the family therapeutic treatment process. This was done as a qualitative methodological triangulation in a case of the family of a 10-year old psychotic boy. The study suggests that assimilation model is suitable for many kinds of data in analyzing family therapeutic treatment processes, makes the change more comprehensible, and yields information about the effectiveness of experiential family therapy techniques.     

Induction of Relational Schemas: Common Processes in Reasoning and Complex Learning

Five experiments were performed to test whether participants induced a coherent representation of the structure of a task, called a relational schema, from specific instances. Properties of a relational schema include: An explicit symbol for a relation, a binding that preserves the truth of a relation, potential for higher-order relations, omnidirectional access, potential for transfer between isomorphs, and ability to predict unseen items in isomorphic problems. However relational schemas are not necessarily coded in abstract form. Predictions from relational schema theory were contrasted with predictions from configural learning and other nonstructural theories in five experiments in which participants were taught a structure comprised of a set of initial-state,operator → end-state instances. The initial-state,operator pairs were presented and participants had to predict the correct end-state. Induction of a relational schema was achieved efficiently by adult participants as indicated by ability to predict items of a new isomorphic problem. The relational schemas induced showed the omnidirectional access property, there was efficient transfer to isomorphs, and structural coherence had a powerful effect on learning. The “learning to learn” effect traditionally associated with the learning set literature was observed, and the long-standing enigma of learning set acquisition is explained by a model composed of relational schema induction and structure mapping. Performance was better after reversal of operators than after shift to an alternate structure, even though the latter entailed more overlap with previously learned tasks in terms of the number of configural associations that were preserved. An explanation for the reversal shift phenomenon in terms of induction and mapping of a relational schema is proposed. The five experiments provided evidence supporting predictions from relational schema theory, and no evidence was found for configural or nonstructural learning theories.     

Habituation To The Reinforcer May Contribute To Multiple-schedule Behavioral Contrast

Habituation to the reinforcer may contribute to multiple-schedule behavioral contrast. According to this argument, reducing reinforcers in one component of a multiple schedule reduces habituation to the reinforcer. Reducing habituation enhances the value, or effectiveness, of the remaining reinforcers, producing positive contrast. Enriching the reinforcers in one component increases habituation to that reinforcer. Increasing habituation decreases the effectiveness of the reinforcer, producing negative contrast. Such an idea is simple and parsimonious. It is not contradicted by any well-established finding in the contrast literature. It makes several tested and untested predictions that are unusual. However, habituation cannot explain all contrast. A complete explanation requires postulating that at least one additional mechanism, controlled by the conditions of reinforcement in the following component, also contributes to contrast.

The Rise of Russian Neo-Kantianism: Vvedenskij's Early ‘Critical Philosophy’

This essay is a study of Vvedenskij's works starting from his 1888 dissertation up to the turn of the century. I attempt to show that although his explicit aim was to update Kant's philosophy of science in light of developments in physics in the 19th century, Vvedenskij departed considerably from Kant's position with respect to both first philosophy and reflection on the achievements of the natural sciences. Vvedenskij's increasing concern with practical philosophy in the 1890s led him to correct a perceived anomaly in Kant's position by postulating a time in itself, an unrecognized consequence of which would be to undermine the apodicticity of mathematics.     

An on site stress workshop for teachers: The creation of a therapeutic group environment

This paper describes an ongoing stress workshop conducted for 5 years in an elementary school. The school was located in an economically deprived area in the Bronx, New York. Similarities and differences between on-site workshops and therapy groups are discussed. The developmental stages of the group and its corresponding issues are analyzed in terms of group process, transference, and resistance. Illustrative vignettes are presented. The positive effects of group dynamic and group therapy interventions on the participating group as well as on nongroup personnel is demonstrated. Suggestions for adapting group therapy methods in school settings are also presented.This paper was presented as a poster at the Annual Conference of the American Group Psychotherapy Association held in Atlanta, Georgia, February 1995.

Reflections on peer review practices in committees selecting laureates for prestigious awards and prizes: Some relevant and irrelevant criteria

An important function in all scholarly and academic activities is the participation in the peer review system. One aspect of this peer review evaluation is service on committees judging candidates for important awards, prizes and fellowships. Some reflective observations on this process are made in which a number of factors determining the final choice are identified. It is pointed out that the decisions of such committees are based not only on relevant and objective criteria but are also influenced by a number of irrelevant criteria; caution must be exercised to minimize the effect of the latter factors in order to maintain the highest ethical standards in the selection process. The ranking practices of awards committees, national academies and learned societies are briefly reviewed by pointing out some ethical pitfalls, anecdotal incidents, and the ways to avoid the tarnishing of the selection process.
