TL;DR

A process model of single-trial free recall which conforms to the constraints imposed by convolution and correlation is presented and some of the strengths and limitations of the model are discussed and contrasted with those of other models of free recall.

Abstract

In this paper, the mathematical operations of convolution and correlation will be proposed as mechanisms by which associative encoding and retrieval may occur, and a process model of free recall which conforms to the constraints imposed by these operations will be presented. In the first section of the paper, the operations will be metaphorically described and defined; computer simulations which demonstrate some of the properties will be presented; and restrictions imposed upon a system which uses these operations will be outlined. In the second section, a process model of single-trial free recall that is compatible with the proposed mechanisms is presented. In the third section, a simulation of the model is applied to a variety of experimental situations and the results of the model are compared to observed results. In the final section, some of the strengths and limitations of the model are discussed and contrasted with those of other models of free recall.
