"In their relative evening, late risers are more alert and can outperform early birds in a reaction time test assuming they're allowed follow their natural sleep rhythm, whereas there are no such differences in the morning" would be a more accurate title...
The paper also gives insights relative to the neural processes involved.
- Goladus 17y agoThere's that term again. How do we know that real life "early birds" and "late risers" are actually following their natural sleep rhythms?
- pygy 17y agoSome do, some don't. Most people go back to their natural patterns during the holidays, though. The classification is based on forms asking questions in a context of freedom from external constraints. I'm not very familiar with sleep research, but I'd guess that both types will underperform if their natural penchant is disturbed (by work hours, for example).

Extreme early and late subject are further "diagnosed" with more exhaustive tests.
