Reaction Time 1

Experimental Objectives:

1. Observe the effect of learning and the effect of anticipating the stimulus delivery on reaction time.
2. Compare reaction times in four stimulus-response situations:
1. Fixed interval stimulus presentation using the dominant hand for the response.
2. Random interval stimulus presentation using the dominant hand for the response.
3. Fixed interval stimulus presentation using the nondominant hand for the response.
4. Random interval stimulus presentation using the nondominant hand for the response.
3. Compare the reaction times for groups of subjects by calculating the statistics of group mean, variance, and standard deviation in each of the four stimulus-response situations.
