This paper derives the basic expressions for the memory-probe dot product for the 2x2 cases, and then applies these expressions to judgments of frequency (JOF) and judgments of recency (JOR).
Abstract
TODAM is a theory of distributed associative memory based on the convolution-correlation formalism of A. Borsellino and T. Poggio (1973, Kybernetik, 122, 113-122), and TODAM2 is a revised version which includes context, auto-associations for binding, a dual basis for item information, and mediators for associative information. It can explain some complex interactions (differential forgetting and differential attention) between item and associative information. In this paper we derive the basic expressions for the memory-probe dot product for the 2x2 cases (item and pair study crossed with item and pair probe), and then we apply these expressions to judgments of frequency (JOF) and judgments of recency (JOR). We report an experiment which tests both JOF and JOR for single items with post-cuing to control for encoding strategies and suggest an attenuation factor for repetition to improve the fits. With attenuation, TODAM2 can fit the JOR data, but the JOF fits, while not too bad, consistently predict too much dependence between item and associative information. Copyright 2001 Academic Press.

A theory of memory retrieval is developed and is shown to apply over a range of experimental paradigms, and it is noted that neural network models can be interfaced to the retrieval theory with little difficulty and that semantic memory models may benefit from such a retrieval scheme.

In conducting vocabulary learning experiments, I have been struck by the incredible variability in learning rates across subjects; even Stanford University students, who are a fairly select sample, display impressively large betweensubject differences.

This work has shown that the relation a#b=S(a * Sb), whereS is an involution which reflects the order in the integral domainZ on which the sequences are defined, can be used to represent a non-associative correlation algebra by an associative convolution algebra equipped with the involutionS.
