Document Summary
Compatibility refers to the relationship of stimuli and responses to human expectations: if the required response to a given stimulus is unexpected , the execution of that response is impeded. The extent to which the stimulus and the response it evokes are connected in a natural way. For a given number of s-r alternatives, increasing s-r compatibility decreases choice. In more general terms, s-r compatibility refers to variations in performance (usually indexed by rt) that will results 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. Traditionally thought that compatibility effects occur as a process of recoding (ie, the translation of environmental info into action) The greater the degree of compatibility: the faster the learning, the faster the response times, the fewer the errors, the greater the reduction in mental workload, and the greater the user satisfaction.
