ABSTRACT
Stimulus-response compatibility (SRC) effects are differences in speed and accuracy of responding as a function of the relation or mapping between stimulus and response sets. Such effects are neither perceptual nor motoric in nature. Rather, they are due to response-selection processes that intervene between stimulus identification and response execution (Proctor and Vu 2003). An operator can respond faster and more accurately when the mapping of display elements to controls is highly compatible than when it is not.
