stimulus-response compatibility

Stimulus-response compatibility refers to how easily and naturally a person can respond to a stimulus based on how well the stimulus and the response are aligned. When the location, shape, or nature of a stimulus matches or corresponds closely with the expected or intuitive response, people tend to react faster and with less effort. Conversely, if the stimulus and response mismatch or seem unrelated, reactions tend to slow down and become more error-prone. This concept is important in designing user interfaces, controls, and signals to enhance efficiency and reduce mistakes.
