Abstract
Two groups of rats were given 50% partial reinforcement for 192 trials in a straight alley, eight trials a day. For one group the intertriai interval was 12 min, for the other, 20 sec. Faster performance was found on trials following reward throughout training at a 20-sec intertriai interval, but this effect was not observed at a 12-min intertriai interval.
