Stimulus Discr1minability and S-r Compatibility: Evidence for Independent Effects in Choice Reaction Time
In contrast to flexible capacity theories of information-processing behavior, discrete stage models generally assume that the functioning of one stage (e.g., stimulus discrimination) proceeds independently of the demands on some other stage (e.g., response selection). These alternatives were tested by factorially varying stimulus similarity and stimulus-response compatibility in a speeded brigh...
متن کاملS-R compatibility: spatial characteristics of stimulus and response codes.
The present paper reports the results of two experiments designed to demonstrate the utility of the concept of stimulus-response compatibility in the development of a theory of perceptual-motor behavior. A task involves compatible S-R relations to the extent that the ensemble of stimulus and response combinations comprising the task results in a high rate of information transfer. Admittedly, de...
متن کاملS-R compatibility effects: Do we need a new theory?
It has been known for many years now that reaction time (RT) to a stimulus is shorter when its relative spatial location corresponds to the relative location of the required response (e.g., Fitts and Seeger, 1953). This result, termed the stimulus-response (S-R) compatibility effect, has been explained by Simon (Simon, 1968; Simon & Rudell, 1967)as arising from a natural tendency to respond tow...
متن کاملAge Factors Influencing Response-Response Compatibility in Reaction Time Tasks
Unlike stimulus-response compatibility, which has been explored for aging effects, the motor behavior issue of response-response (R-R) compatibility has not been addressed in the gerontological literature. R-R compatibility refers to the ease with which two responses can be prepared together either simultaneously or as choice alternatives. In the present study, young, middleaged, and elderly ad...
متن کاملReaction time as a function of perceptual bias, response bias, and stimulus discriminability.
The effects of stimulus discriminability, stimulus frequency, and response frequency were examined in a choice reaction time (RT) task. Two levels of response frequency ratio (i.e., one of two responses occurred two or five times as often as the other) were combined with three levels of stimulus configuration. Configuration was defined by the spatial distance between three stimulus lights. Perc...
