A few studies show that character traits may differ between the diurnal and the nocturnal.
A Spanish researcher found that the time of day we prefer to be most active corresponds to certain personality traits. Early risers were more likely to be logical and analytical, and likely to use concrete information as sources of knowledge, whereas those that stayed up late were more imaginative and intuitive.
Another study published in the February 2007 issue of Personality and Individual Differences determined that night owls scored better on creativity tests than did intermediary and morning people.

The circadian rhythm, a 24.1-hour period that dictates the sleep-wake cycle, differs among people and can influence whether we are a night owl or a morning lark.
Studies have indicated that self-described morning people have shorter circadian rhythms than self-identified night owls. This means that morning people sleep through their peak hour of sleepiness, so they wake up feeling refreshed.
Evening types usually wake up right around their peak hour of sleepiness, so they may have high levels of melatonin and feel groggy. No wonder it’s tough to rouse them.
