Document Summary
Compatibility refers to the relationship of stimuli and responses to human expectations: if the required response to a given stimulus is unexpected(cid:495), the execution of that response is. Ie. the extent to which the stimulus and the response it evokes are connected in a (cid:494)natural(cid:495) impeded. way. 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. Pairing that lead to shorter rts are considered compatible and vice versa. For example, for any given number of s_r alternatives, increasing s_r compatibility decreases choice rt (ie. uncertainty is decreased). One of the most robust findings in motor control is that the correspondence between stimuli and response locations (spatial compatibility) is an important determinant of speed of response (fitts & seeger)
