The article consists of an interview with John Ohliger of Basic Choices, Incorporated in Madison, Wisconsin. The interview was completed during a trip to Australia. Conversation mainly focuses on learning theory and lifelong learning. (CH)

The objective of this article is to develop baseline models showing principal approaches to category learning. All models are based on a common memory array but vary in memory access and decision processes useful for interpretation of empirical phenomena. The main models discussed are exemplar, prototype, and feature. (JAZ)

Argues that, as scientists learn more about the chemistry and physiology of the human brain, it is incumbent upon educators and educational psychologists to begin to build models of brain function that reflect growing scientific knowledge. (FL)

Reviews educational research in terms of Ausubelian learning theory and finds that the data reported can be interpreted as consistent with these theories, although many studies cited were inadequate for critical testing of the theories. Cites 10 studies concerning amount of instructional structure, 21 comparing group and individualized…

Earlier Analyses are shown to involve special cases of the equations developed here; also that a general four-state chain has the same parameter space as an all-or-none model if and only if its representation with an observable absorbing state is lumpable into a Markov chain with three states.
