Retention over a period of REM or non‐REM sleep
Abstract
The aim of this study was to test the hypothesis that REM sleep is a phase of intensified memory consolidation. Pairs of subjects were woken in the middle of the night and presented with a categorizable list of 24 words in the form of six four‐word quartets. Arousal measures (CFF) were taken and immediate free recall attempted before sleep was resumed. Subjects were reawakened at the beginning or end of their next REM period and tested for retention following further CFF trials. Recall was facilitated when a period of REM sleep intervened during the retention interval, but deteriorated when sleep was composed entirely of non‐REM (NREM) sleep stages. The relative improvement following REM sleep was found to be a function of higher retrieval efficiency. It was suggested that either the high arousal associated with REM sleep incidentally maintained the memory trace in a more retrievable form or that REM sleep facilitates consolidation giving rise to improved retrieval.

Most studies failed to find effects of selective REM sleep deprivation on the retention of declarative memories when simple verbal materials were used.
“Most studies failed to find effects of selective REM sleep deprivation on the retention of declarative memories when simple verbal materials (word lists, word pairs, etc.) were used (88,185,192,343,344,729,918,1094,1191).”

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.
