Reactions

Reactions may be defined simply as the time between a stimulus and a response. Three basic reaction time paradigms have been described:

• 1. Simple reaction time has a single stimulus and a single predefined response.
• 2. Recognition reaction time has several false stimuli mixed with one correct stimulus prompting the response.
• 3. Choice reaction time involves multiple stimuli and differing responses for each stimulus. Serial reaction time is a combination of recognition and choice reaction time, where the stimulus is a repeating sequence that the subject must learn to predict and then to respond in a prescribed fashion.

An example of simple reaction time would be the time from a buzzing sound to moving a finger. Adding false chime or ring sounds would convert the model to recognition reaction time, while creating different responses for the chime or other ring sounds would convert the model to a measurement of choice reaction time.
