Memory and time of day
TLDR
Subjects performed a memory task on two occasions, one in the morning and the other in the afternoon, in which one nine-digit sequence is surreptitiously repeated, each repetition being separated by two non-repeated sequences.Abstract:
Subjects performed a memory task on two occasions, one in the morning and the other in the afternoon. The task comprised two components, one involved immediate recall of sequences of nine digits, the other involved the repeated item technique devised by Hebb (1961), in which one nine-digit sequence is surreptitiously repeated, each repetition being separated by two non-repeated sequences. Performance on the immediate memory task was better in the morning than the afternoon. The repeated item was recalled more accurately than non-repeated items, but this effect was not influenced by time of day. An explanation in terms of the relationship between arousal and memory reported by Kleinsmith and Kaplan (1963) is suggested.read more

Optimal Time of Day and the Magnitude of Age Differences in Memory
TL;DR: In this article, age differences in optimal performance periods were identified, and then shown to be an important determinant of memory differences (Study 2) across two studies comparing younger and older adults, and was found to be a critical variable in determining group differences in intellectual performance, particularly between older and younger adults.

Short-term memory, alertness and performance: a reappraisal of their relationship to body temperature
TL;DR: Contrary to earlier findings, it is reported here that the circadian rhythm of short‐term memory varies in parallel with the circadian rhythms of subjective alertness, calculation performance, and core body temperature under both these experimental conditions.

Diurnal variation in logical reasoning.
TL;DR: The results are interpreted as indicating that the different functions relating performance efficiency to time of day found by previous workers are due to differences in task demands rather than to individual differences.

Circadian rhythms in human memory
Simon Folkard,Timothy H. Monk +1 more
TL;DR: In this paper, the authors examined the influence of time of day of presentation on immediate and delayed retention, and the potential effects of time-of-day on retrieval from long-term memory.

Sleep and wakefulness
TL;DR: For half a century, "Sleep and Wakefulness" has been a valuable reference work as discussed by the authors It discusses phases of the sleep cycle, experimental work on sleep and wakefulness, sleep disorders and their treatment, and such sleep-like states as hypnosis and hibernation.

Amnesia and the distinction between long- and short-term memory.
TL;DR: Comparisons of the performance of amnesic and control S s on immediate and delayed free recall, the Peterson short-term forgetting task, development of PI in STM, minimal paired-associate learning, digit span, and the Hebb repeated digit-sequence technique suggest that amnesics S s have normal STM but defective LTM.
