Résumé :

Previous experiments showed that serial choice RT is longer on the trials where the stimulus is different from the preceding one. The influence on this phenomenon of the duration of the time-lag between the end of the response and the arrival of the next signal was examined. 16 Ss gave 600 responses on each of 4 sessions on a self-paced two-choice task, where they responded with one of two keys to the presentation of one of two shapes. Response-signal intervals of 50, 200, 500 and 1000 msec were presented, following both a regular and an irregular procedure. Under both procedures, the difference between RTs to new and two repeated stimuli was shown to decrease with the passage of time. © 1966.
