Effects of early and late nocturnal sleep on priming and spatial memory

Plihal, Werner, Born, Jan·1999·Psychophysiology

Abstract

A wordstem priming task (nondeclarative memory), and a mental spatial rotation task (declarative memory) were presented to subjects of an experimental “sleep” group (n= 11) and of a “wake” control group (n= 10). Repetition priming effects and recall of spatial memory were tested after 3‐hr retention intervals, which followed learning and were placed either in the early or in the late half of the night. Sleep group subjects slept during the retention intervals while subjects of the wake group stayed awake. As expected, early retention sleep was dominated by slow wave sleep (SWS), whereas rapid eye movement (REM) sleep prevailed during late retention sleep. After early retention sleep, recall of spatial memory was superior to that after late retention sleep (p < .01), and also to that after retention intervals of wakefulness (p < .05). In contrast, priming was more effective after late than early retention sleep (p < .05). It appears that early sleep dominated by SWS facilitates consolidation of declarative memory whereas late sleep dominated by REM sleep facilitates consolidation of nondeclarative memory.

  • If at all, REM sleep benefits aspects of a memory not essentially depending on the hippocampus, i.e. procedural features of memory.

    “This view is also in agreement with the fact that, if at all, REM sleep benefits aspects of a memory not essentially depending on the (binding function of the) hippocampus, i.e. procedural features of memory (Plihal & Born 1997; Plihal & Born 1999).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
