WebReaction time is the time between any kind of event and the response it elicits in a system. The brain is an essential part of developing a quick reaction time. In this experiment, the eye sees that the ruler has been dropped. This information travels from sensory neurons along the optic nerve from the eye to the brain. WebReaction time to touch is intermediate, at 155 msec (Robinson, 1934). Differences in reaction time between these types of stimuli persist whether the subject is asked to make a simple response or a complex response (Sanders, 1998, p. 114). Stimulus Intensity 1.
