Abstract

The present study explores the relationship between human REM sleep and time-dependent memory consolidation processes. Specifically, it was hypothesized that differential effects on retention produced by post-learning REM sleep deprivation may be explained in terms of neuropsychological dissociations of task requirements. In order to test this possibility, a variety of memory tasks were assembled to be representative of subsets within both explicit/declarative and implicit/procedural domains. These include: Word Recognition, Word Fragment Completion, Tower of Hanoi, Corsi Block-Tapping Task, and the Rey-Osterrieth Complex Figure. Thirty-five undergraduate students from Trent University, Peterborough served as subjects. Subjects were presented with the stimulus materials in the evening, followed by random assignment to one of five sleep conditions: (1) Selective REM Sleep Deprivation; (2) Non-REM Sleep Deprivation; (3) Total Sleep Deprivation; (4) Lab Recorded Controls; or (5) Normally Rested Controls. Subjects were post-tested with the same materials after a 1-week retention interval. Results indicated that selective REM sleep deprivation following learning impaired retention of implicit priming and cognitive procedural learning while sparing explicit/declarative material. Results are discussed within a variety of theoretical frameworks, including distinct memory systems theories and accounts derived from the area of human information processing.Dept. of Psychology.
