Scheduled-training of cats to a simple reaction time performance

Cats were trained to release a lever at the onset of a sound, using a simple reaction time paradigm with different foreperiods. The training of the subjects was controlled by a PDP 8/L computer with a training schedule that avoided the problems of manual shaping except for the preliminary step, the lever press. This schedule successfully trained the cats in about 6 daily sessions up to the reaction time paradigm with a 3 sec criterion. In contrast, a programme designed to reduce the criterion value so as to induce the subjects to perform shorter latency movements failed because the cats learned to control it through an escape procedure.
