This is an experiment about music and reaction speed.
There are 10 rounds. Each round, you will be listening to a different genre of music.
When you begin, you will see an outlined area. After a short delay, a blue
box (the target) will pop up somewhere inside the area. The target will show a letter inside it.
Move the mouse over the box and press the key shown to 'hit' the target.
The round will end once 10 targets have been hit.
