Jeffrey's rule of conditioning has been proposed in order to revise a probability measure by another probability function. We generalize it within the framework of the models based on belief functions. We show that several forms of Jeffrey's conditionings can be defined that correspond to the geometrical rule of conditioning and to Dempster's rule of conditioning, respectively. 1. Jeffrey's rul...

A theory of hypnosis based mainly on principles of conditioning and inhibition is proposed, covering the hypnotic induction process, hypnotic phenomena and post-hypnotic phenomena. The overall explanation presented is delineated in a set of three initial postulates and seven subsequent hypotheses. Hypnotic induction is defined as the giving of a series of suggestions so that a positive response...

statement of problem: considering the cost and amount of time and also the quantity of tooth loss in the process of cavity preparation, repair of the restoration instead of its replacement would be much more efficient. purpose: the aim of this study was to determine the effect of different methods of surface conditioning on the shear bond strength of repaired compomers. materials and methods: s...

This paper describes characteristic behaviors of my father, B. F. Skinner, using family documents and my own recollections. Early contingencies in his upbringing strengthened his love of building things and his independence in discovering how the world works. Those skills, combined with a lack of supervision in graduate school, set the stage for his discovery of the operant. He did not stop wit...

germinated within 24 hours after prior exposure either to blue light or when maintained under complete darkness. However, far-red light augmented the germination of seeds pretreated with 6-benzylaminopurine so that nearly all such seeds germinated within 24 hours after treatment (table II). Far-red light also augmented the rate of germination of seed pretreated with a synergistic mixture of 6-b...

What are the distributional effects of advances in medical care? This important question has been relatively neglected by health economists. I will discuss some of the reasons for this neglect and speculate about possible answers. But first, I will comment on the Skinner-Zhou (S-Z) paper, looking at the questions they address and the answers they provide. Their first question concerns trends in...

The performance of 40 neurotic female patients on finger withdrawal and GSR conditioning to shock was correlated with several personality and objective measures of drive level and cortical inhibition. All correlations between conditioning indices for the 2 responses were positive and significant (p < .05) for this group. The correlations of the drive measures with both conditioned responses wer...

This article examines Skinner’s often neglected ideas about evolution, which he returns to in his final academic paper. I attempt square advocacy for evolutionary explanation, including efforts reconcile biological, individual, and cultural adaptation, with how is framed critiqued by a school of psychologists who attribute Skinner blank slate, or so-called standard social science model, view th...

Resumo Vários estudos rastreando possíveis fontes que teriam norteado Skinner na construção do Behaviorismo sugeriram, de modo pouco preciso, elos científicos entre Claude Bernard e Skinner. Considerando o assunto, este trabalho realizou um comparativo sistemático ambos os autores, através das seguintes categorias: (1) interação organismo-ambiente; (2) mentalismo; (3) indução-dedução; (4) delin...
