Inter-individual differences in the human circadian system: A review
TLDR
It is argued that the differences in rhythm parameters associated with the personality dimension of introversion-extraversion are the result of exogenous influences in the intrinsic period of the circadian system.About:

Cognitive and biological determinants of P300: an integrative review
John Polich,Albert Kok +1 more
TL;DR: The effects of natural and environmentally induced state variables on the P300 suggest that these factors contribute to P300 measures and are discussed in terms of their theoretical and applied implications.
Journal ArticleDOI
Evaluation of three circadian rhythm questionnaires with suggestions for an improved measure of morningness.
TL;DR: A 13-item scale was developed that distills the best items from two of the widely used circadian rhythms scales, and Relationships between the new composite scale and external criteria are comparable with or stronger than similar relationships between the published scales and internal criteria.

Horne & Ostberg morningness-eveningness questionnaire : A reduced scale
Ana Adan,Helena Almirall +1 more
TL;DR: In this paper, a reduced scale of Horne & Ostberg's Morningness-Eveningness questionnaire is presented, which only contains questions about Morningness, which helps to define this dimension better.
Journal ArticleDOI
Individual differences in the phase and amplitude of the human circadian temperature rhythm: with an emphasis on morningness-eveningness.
TL;DR: An association between circadian rhythm temperature phase and amplitude was found, in that subjects with more delayed phases had larger amplitudes and the greater amplitude was due to lower nocturnal temperature.

Ana Adan,Vincenzo Natale +1 more
TL;DR: The aim of this study was to analyze gender difference in morningness–eveningness preference using the Horne and Östberg questionnaire in the largest university student population selected so far.

A self-assessment questionnaire to determine morningness-eveningness in human circadian rhythms.

TL;DR: Although the questionnaire appears to be valid, further evaluation using a wider subject population is required, as sleep habits are an important déterminant of peak time there are other contibutory factors, and these appear to be partly covered by the questionnaire.

TL;DR: Two- to threefold variations in sleep length were observed in 12 subjects living on self-selected schedules in an environment free of time cues and the duration of polygraphically recorded sleep episodes was highly correlated with the circadian phase of the body temperature rhythm at bedtime.
