Spacing Effects in Learning Described by the SAM Model. Comparing Three Versions of the SAM Model

摘要

In learning, repetition is known to improve performance, but the form of presentation (massed or spaced) is also a factor in recall. The report presents a model for spacing and repetition based on the SAM theory for memory retrieval. Three versions of the model are compared. Two are related to a verbal theory, the so-called components-level theory, in which context fluctuation is used to explain spacing effects. In the third, decay of trace strength is used.
