How is reaction time affected by the time of the day?
I need to know how reaction time is affected by the time of day, and i'm testing using a ruler-drop test. I drop a ruler and the participant has to catch it as fast as possible. I'd like some proper scientific theory behind why reaction time might vary throughout the day, (morning, lunch, afternoon, night), and possibly using connections to neurones and nerves/hormones. THANKS!
best answer can be sure to be award with max points!

I can't remember exact times, but basically you're on about chronobiology. All species have 'peak activity times', that they are usually most active at (as a result of evolutionary pressure in their environment/ecological niches). This is controlled by various molecular mechanisms throughout the body. These complex molecular mechanisms control the levels of various hormones/neuroactive chemicals that are released at certain times, resulting in alertness or sleepyness.
Humans vary a little, some people are morning people, whereas others are not (this is controlled by genetics and social pressures, such as working hours). But, most humans tend to be most alert in the mornings.
It's a huge field, so this is just a vague summary, it depends how much you need to write.
