Cognitive processes in extinction.
Human conditioning research shows that learning is closely related to consciously available contingency knowledge, requires attentional resources, and is influenced by language. This research suggests a cognitive model in which extinction consists of changes in contingency beliefs in long-term memory. Laboratory and clinical evidence on extinction is briefly reviewed, and it is concluded that t...
متن کاملExtinction times in Multitype Markov Branching Processes
In this paper, a distributional approximation to the time to extinction in a subcritical continuous-time Markov branching process is derived. A limit theorem for this distribution is established and the error in the approximation is quantified. The accuracy of the approximation is illustrated in an epidemiological example. Since Markov branching processes serve as approximations to nonlinear ep...
متن کاملContext and behavioral processes in extinction.
This article provides a selective review and integration of the behavioral literature on Pavlovian extinction. The first part reviews evidence that extinction does not destroy the original learning, but instead generates new learning that is especially context-dependent. The second part examines insights provided by research on several related behavioral phenomena (the interference paradigms, c...
متن کاملCognitive processes in hypertension.
In 15 normotensive subjects, 17 newly diagnosed, untreated hypertensive patients, and 22 effectively treated hypertensive patients, a battery of neuropsychological tests was given. All subjects were neurologically asymptomatic. The neuropsychological battery included tests evaluating global cognitive functions (Card Sorting Test, Wechsler Memory Scale, Progressive Matrices 1938), as well as spe...
متن کاملProcesses affecting extinction risk in the laboratory and in nature.
A fascinating laboratory experiment byHufbauer et al. (1) manipulates genetic diversity and population size of flour beetles (Tribolium castaneum) in the face of a change in the resource base offered in experimental microcosms. The experiment finds that extinction risk is offset to a comparable degree by adding a few genetically diverse individuals or by more substantially elevating population ...
