Research Strategy in the Study of Memory: Fads, Fallacies, and the Search for the "Coordinates of Truth"

This article presents an evaluation of research strategy in the psychology of memory. To the extent that a strategy can be discerned, it appears less than optimal in several respects. It relates only weakly to subjective experience, it does not clearly differentiate between structure and strategy, and it is oriented more toward remembering which words were in a list than to the diverse functions that memory serves. This last limitation fosters assumptions about memory that are false: that encoding and retrieval are distinct modes of operation; that the effects of repetition, duration, and recency are interchangeable; and that memory is ahistorical. Theories that parsimoniously explain data from single tasks will never generalize to memory as a whole because their core assumptions are too limited. Instead, memory theory should be based on a broad variety of evidence. Using findings from several memory tasks and observations of everyday memory, I suggest some ways in which involuntary reminding plays a central role in cognition. The evolutionary purpose of memory may have been the construction and maintenance-through reminding-of a spatio-temporal model of the environment. I conclude by recommending ways in which efficiency of the field's research strategy might be improved.
