title: How to differentiate retrieval from storage deficit: a stochastic approach to semantic memory modeling.
abstract: Some of the methods currently used to differentiate retrieval from storage deficits in brain damaged patients are revisited. Indices based on association or agreement measures among the responses given by the subject on repeated trials, as well as direct estimates of storage and retrieval abilities based on crude percentages, are open to criticism. A simple Markov chain stochastic approach, which is free of the drawbacks of the other methods and which distinguishes storage from retrieval deficits more reliably and powerfully, is proposed.
