Abstract
Experimenters have been devising questionnaires to distinguish so-called morning (M) and evening (E) types since the turn of the century, yet with rather inconsistent findings (Home and östberg, 1977). More recent studies with M- and E-types have confirmed differences in the circadian course of body temperature, performance and subjective alertness (Horne et al., 1980; Forêt et al., 1982).
