Abstract

During the last two decades, the research about Morningness-eveningness (M/E) has significantly thrived. ME describes the timing of sleeping and the preference for evening or morning hours for mental and physical performance. ME is viewed as an interesting aspect of personality, and the psychometric measurements have been well-established and validated. Apart from a genetic basis, hormones and social factors mediate ME, and it is related to many psychological aspects, e.g., other personality measures, as well as to psychopathology, e.g., depression. We feel that the time is ripe for a symposium covering a wide variety of aspects, including the measures of ME, their validity and reliability, their biological basis, a look at applied aspects, like school functioning, and at psychopathology such as depression or other disorders, as well as other health-related problems, like addiction, eating disorders and obesity. The symposium will give an overview and define new venues of research.
