Morningness and eveningness personality: A survey in literature from 1995 up till 2006

The article investigates central aspects of Morningness–Eveningness personality, focusing on recent literature in this field from 1995. A review was written by Kerkhof (1985) about interindividual differences in the human circadian system, where the author reviewed previous studies which had dealt with some aspects of Morningness–Eveningness personality (questionnaires, circadian rhythms, sleep-wake cycle, introversion–extraversion, age, sex, and the impact of disturbance) and a review was written by Tankova, Adan, and Buela-Casals (1994) about circadian typology and individual differences, where aspects of personality, age, sex, shift work, and life habits were examined. This paper, with reference also to previous studies, attempts to give an updating survey of some issues of the literature in the field of Morningness–Eveningness personality from 1995 up to 2006; various aspects of Morningness–Eveningness personality are taken into consideration: personality traits, biological, and genetic issues, Morningness–Eveningness preferences in Youngs and Adults, gender, cognitive abilities, work schedules, life habits, and cross-cultural research.
