This experiment conducted three different experiments to determine these results‚ all of which involved continuous reinforcement to teach Sniffy to learn to press the bar for food pellets. It was predicted that Sniffy is likely to learn to extinguish the behaviour that is learned faster when the level of punishment is higher. The first experiment went through an extinction trial and Sniffy was not given food following the bar press;
