The influence of intertrial interval durations ranging from 7 to 30 s upon sucrose detection thresholds of sixteen subjects was investigated by means of a modified staircase procedure with intertrial rinses. In addition, the influence of the sex of the subject was examined. Neither the intertrial interval nor the sex of the subject significantly affected sucrose detection thresholds. The results suggest that, in sucrose detection threshold studies using the present procedure, one can employ intertrial intervals as short as 7 s without significantly affecting the threshold value.
