| With regards to ], '''reaction time''' is the time from the ] of a ] until the organism responds. | |||
| ==Types== | |||
| *Simple reaction time is the time it takes to react to stimuli. | |||
| *Complex reaction time is the latency between a variable stimulus and a respectively variable response. | |||
| ** Go/NoGo (also called Recognition) reaction time task in which participants respond to one particular event but ignore other events | |||
| ** Choice reaction time task in which participants respond differentially to two stimuli by pressing one key for event A and a separate key for event B. | |||
| At the University of New South Wales, slower reaction times has been studied as a contributing factor in falls of elderly.<!-- Refer to the author, Stephen Lord, pertaining to a book on reducing falls, which was published after the study of 80,000 older Australian citizens. | |||
| --> | |||
| ==Factors== | |||
| The major factors affecting reaction time are: | |||
| *Recognition | |||
| *Choice <!-- what choice? this could be clearer --> | |||
| *Number of stimuli | |||
| *Type of stimulus | |||
| *Stimulus intensity | |||
| *Diseases, such as chicken pox | |||
| *Distractions <!-- *The Actual Test affects more than 100,002,288 people in everyday life. --> | |||
| *] | |||
| There are many other factors that can also affect reaction time: | |||
| *Practice and error | |||

| ==History of the field == | |||
| Physical scientists such as ] and philosophers such as ] conducted many observations involving aspects of chronometric measurement; however the tools or impetus to measure cognitive reaction time apparently was not developed, or simply has not left a significant traceable thread in the literature. The literature in other fields, e.g., epigraphical evidence, remnants of papyri, sherds, and other source material is uncertain and warrants additional investigation. An understanding of physical reaction time is critical for fields such as ballistics, archery, athletics and the physical sciences in order to estimate and measure. | |||
