Choice Reaction Time (CRT)

What is Choice Reaction Time (CRT)?

Choice Reaction Time (CRT) is a measure of the time it takes for an individual to respond to one of several stimuli by selecting the appropriate response from multiple options. Unlike Simple Reaction Time (SRT), which involves responding to a single stimulus with a single response, CRT requires decision-making and discrimination between different stimuli before executing the correct action.

For example, in a CRT test, a person might be presented with different colored lights, each requiring a different button press. The time it takes to perceive the stimulus, decide which response is appropriate, and then execute that response is measured as the Choice Reaction Time.

CRT is used to assess cognitive processing speed, decision-making abilities, and motor coordination. It is commonly employed in psychological research, sports science, and various fields that require quick decision-making and response, such as driving and air traffic control. Factors such as complexity of the task, the number of choices, and individual differences can all influence CRT.
