AS Reaction Time

ASAQA reaction time

Reaction time The time between onset of a signal to respond (stimulus) and the initiation of that response
Response Time The time from the onset of signal to respond (stimulus) to the final completion of the response or action
Simple reaction time A specific reaction to a specific response (one stimulus one response)
Choice Reaction time Either a performer has to respond to several stimuli all requiring a response or they have to respond correctly to one from a choice of several
Movement Time The time from the initiation of the first movement to the completion of the movement
Hicks Law Reaction time will increase logarithmically as the number of stimulus response choices increase
Single channel hypothesis Suggests that a stimulus is processed along a single nerve track and the brain can only process one stimulus at a time
Psychological refractory period (PRP) Only one stimulus can be processed at a time so if a subsequent stimulus is received before the original one is processed there is an unavoidable delay
Spatial anticipation The performer predicts when the action will happen
Temporal anticipation The performer predicts what is about to happen
