Sensory-feedback persistence in determining memory

Abstract

Investigated sensory feedback persistence as a factor in determining memory by varying the display persistence of both a to-be-learned stimulus pattern and a memory-reproduction stimulus pattern, and then measuring the effects of this variable feedback persistence on reproduction of the stimulus-wave pattern. A hybrid computer system regulated aspects of feedback control of the motorsensory factors in the learning and memory procedures and measured error in the dynamic memory tests. Results specifically confirm the hypothesis that spatial factors in learning, as produced by persistence of a visually tracked pattern, function as time-spanning processes to encode time in memory and thus to make possible feed-forward projection and prediction of behavior on a space-time basis. Findings support the view that learning and memory are interrelated time-spanning and space-time projection processes in behavior, and govern the sense of time in the past and future rather than being determined by factors of time contiguity and temporal association of separate discrete responses.
