Document Summary
Stove-top w/no info included about which knob controls which element. Compatibility refers to the relationships of stimuli and responses to human expectations: if the required response to a given stimulus is unexpected , the execution of that response is impeded. One of the most robust findings in motor behaviour is that the correspondence between stimuli and response locations (spatial compatibility) is an important determinant of speed of response (fitts & seeger, 1953) Discussed in terms of spatial compatibility where response and stimulus dimensions are in space relative to each other. Fitts studied it, made fits law determined the idea of spatial correspondence between stim and response is important for determining speed and accuracy. In more general terms, s-r compatibility refers to variations in performance (usually indexed by rt) that will result as a function of the ways in which specific stimuli are paired with their associated responses. Pairings that lead to shorter rts are considered compatible and vice versa.
