ABSTRACT
Perception-based knowledge representations store memories of the perceptual structure of events and appear to be processed in neural regions close to where the original perceptions were processed. A comparable duality guides the literature on auditory sensory memory. Many experiments on pure tones show evidence of persistence and masking with a time constraint of about a quarter of a second. The simplest proceduralist attitude towards memory of all kinds would then be that those units active on the original occasion will be changed, thereafter, and will be the “locus” of a memory, whether that activity was top-down or bottom-up. Modern memory theory has more or less embraced proceduralism during the last 20 years. One measure of this has been the wide acceptance of the levels of processing framework for memory, which ties storage to the original operations used in encoding events, and ties storage durability to the “depth” of those operations.
