Abstract

Despite some notable counterexamples, the theoretical and empirical exchange between the fields of learning and memory is limited. In an attempt to promote further theoretical exchange, I explored how learning and memory may be conceptualized as distinct algorithms that operate on a the same representations of past experiences. I review representational and process assumptions in learning and memory, by the example of evaluative conditioning and false recognition, and identified important similarities in the theoretical debates. Based on my review, I identify global matching memory models and their exemplar representation as a promising candidate for a common representational substrate that satisfies the principle of least commitment. I then present two cases in which exemplar-based global matching models, which take characteristics of the stimulus material and context into account, suggest parsimonious explanations for empirical dissociations in evaluative conditioning and false recognition in long-term memory. These explanations suggest reinterpretations of findings that are commonly taken as evidence for dual-representation models. Finally, I report the same approach provides also provides a natural unitary account of false recognition in short-term memory, a finding which challenges the assumption that short-term memory is insulated from long-term memory. Taken together, this work illustrates the broad explanatory scope and the integrative and yet parsimonious potential of exemplar-based global matching models.
