On Manility and Serality

Publication Date



Attention; Arousal (Physiology); Circadian rhythms


The notion that different people consistently function best at different and specific times of day is subjected to further analysis and discussion of methodological difficulties. When factor analytic procedures are applied to behavior inventories which supposedly capture stable diurnal characteristics, more than one dimension of "serality-manility" emerges. Factor scores thus derived were correlated with the computed acrophases of several circadian functions. Certain results suggest sex differences in the underlying structure, besides the magnitude, of these relationships. Also, hormonal contraception may alter behavioral serality-manility.
