| Abstract: | An analysis is given of a simple theory of paired-associate learning in which items may be retained for short intervals before they are learned. Theoretical questions are discussed that involve parameters of the theory, and the problem of identifying these parameters is analyzed. Analyses of several experiments lead to the conclusion that either there is no learning on trials when the presented item is already in short-term memory, or an item usually is learned during the intervals between its presentations. Results of one experiment that permits a choice between these two possibilities favor the assumption that learning occurs mainly during the intervals between an item's presentations. Finally, some statistical methods are presented for the general theory and for the special case that is supported best by the data. |
