Reaction Time

This program measures your reaction time 10 times in a row. It then calculates the average of the ten trials, the standard deviation and the number of times you react before the stimulus is triggered. If the standard deviation is large then the test may not be valid!! It the standard deviation is consistently high, it may be a sign of Attention Deficit Disorder.
This program measures your reaction to a red stimulus.
Have fun.
I would like to give a shout out to Cicilia Chetiar a professor of psychology for her valuable suggestions.
