Why we sleepthe functions of sleep in humans and other mammals. Setting, sleep laboratory in Stockholm, Sweden.

There are many traits that are linked to facial attractiveness in humans and each may in some way impart benefits to individuals who act on their preferences. Overall, we enrolled 12 women and 12 men. If this is the case, then our findings indicate that the behavioral speech task is more likely to be an accurate measure of future parental effort than self-report.

In conclusion, the major contribution of this research has been first to replicate the finding of Roney. Intervention, participants were photographed after a normal nights sleep (eight hours) and after sleep deprivation (31 hours of wakefulness after a night of reduced sleep). Long-term dichotomy is intuitively plausible and has generated data indicating that women's preferences for male partners do indeed change in different mating situations.
