Some experiments on simple and choice reaction time.

Abstract : The report concerns four problems on simple and choice reaction time (RT). First, in Experiments 1 and 2, the suthors examine the role of time estimation in the manipulation of responses in simple reaction time experiments by means of payoffs and information feedback. Second, in Experiment 3, they ask whether the changes in the shape and location of choice RT distributions as compared with simple ones are due primarily to the increase in the number of signals, in the number of responses, or in some more basic difference between the two tasks. Third, in Experiment 4, they investigate the relation between RT and signal presentation probability in choice situations. And, finally, using all of the empirical distributions obtained in Experiments 2, 3, and 4, an attempt is made to see if any of several theoretical distributions appear to give a satisfactory description of the data.
