Choice Reaction Time as a Function of Stimulus versus Response Relative Frequency of Occurrence
Abstract
THE well known fact that choice reactions to alternatives of unequal frequencies of occurrence are faster for the more frequent alternatives has mainly been studied in tasks with a 1 : 1 correspondence between stimuli and responses1-5. In such situations, stimulus and response relative frequencies are confounded and it is impossible to tell which variable is critical in determining the reaction time. An answer to that question would help to locate preparatory adjustments in the chain of processes intervening between reception of the stimulus and production of the response.
