The aural reaction time is way faster then the ocular one. This is partly caused by the lenght of the nerves and he distance signals have to travel on them. best regards simon jessurun > LRZeitlin@aol.com wrote: > > > My old experimental psychology textbooks give the simple reaction time > > of most people as about 200 milliseconds. > > This is largely irrelevant.
