| Abstract: | Theories of learning that predict a negative exponential growth curve are based on the assumption that learning is a process of replacement—incorrect response tendencies are replaced with correct ones. In the present article, an alternate model is presented that describes learning as a process of accumulation where incorrect response tendencies remain constant and correct response tendencies increase with practice. These 2 approaches were compared in their ability to describe the shapes of the learning curves for several experiments in free recall and perceptual and motor learning. In nearly every case, the predictions of the accumulation model were superior, and the predictions of the best fitting replacement equations failed in systematic ways. The relationship between the accumulation model and a reinforcement theory of steady-state responding is discussed. It is argued that the accumulation model should be given greater consideration as a viable model of the learning process. (68 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved) |
