Perception is a cognitive process. There are several steps starting from stimuli reception to reaction of the perciver.
Fundamentally the system involved in a reaction to a stimuli is the nervous system.
A thing or event that evokes a specific functional reaction in an organ or tissue: "areas of the brain which respond to auditory stimuli".
Choice reaction time involves selecting a specific and correct response from several choices when presented with several different stimuli. This type of reaction time is common in situations where a person must make a decision based on multiple stimuli or cues.
