Some Random(ized) Thoughts.
In this EBM Hub edition, we use the interesting, prospective, randomized, double-blinded study of Min et al from this current issue of Aesthetic Surgery Journal as a springboard to address a key methodological issue that is important in the proper execution and reporting of a randomized, controlled trial: themethod of randomization. Randomization is among our most powerful protective mechanisms...
متن کاملOperant variability: procedures and processes.
Barba’s (2012) article deftly weaves three main themes in one argument about operant variability. From general theoretical considerations on operant behavior (Catania, 1973), Barba derives methodological guidelines about response differentiation and applies them to the study of operant variability. In the process, he uncovers unnoticed features of operant variability research (e.g., Neuringer, ...
متن کاملOperant variability: evidence, functions, and theory.
Although responses are sometimes easy to predict, at other times responding seems highly variable, unpredictable, or even random. The inability to predict is generally attributed to ignorance of controlling variables, but this article is a review of research showing that the highest levels of behavioral variability may result from identifiable reinforcers contingent on such variability. That is...
متن کاملOperant Variability and the Power of Reinforcement
Reinforcers contingent on response variability exert powerful and precise control over levels of variability, from stereotypy to stochasticity. This paper reviews how variability-contingent reinforcers interact with non-contingent, eliciting events to influence the variability of operant responses. Relationships to stimulus control, choice, acquisition of new responses, voluntary action, autism...
متن کاملSome Thoughts on Special
Here an introduction to Wesley’s neomechanics is presented. It is shown to produce some of the same results as Special Relativity but without both the mathematical and philosophical basis of that subject. As with other work in which results associated with General Relativity are obtained without recourse to the fundamental bases of that subject, so here too the preeminent place afforded Special...
