In the typical reaction-time experiment, S's reaction time is greater when he has to respond differentially to one of two equally probable stimuli instead of to just one stimulus. In fact, Merkel (2), using one to ten alternatives, has demonstrated that when S has to respond to one stimulus chosen from a number of equally probable alternatives, his reaction time increases with the number of alternatives. The fact that S's response to stimulus A takes more time when A is one of several rather… Expand
