In appendix B, Sniffy is in the continuous reinforcement schedule and under fixed ratio trials and after viewing the cumulative records, Sniffy steadily bar presses after extinction is initated.

Any time the rat performs a sequence and valid is set to false if the rat discovers evidence that its does not get food, that sequence’s probability is a candi- current guess at a schedule is wrong. We have priced the showing the relative probability of a behavior as a function of the product very reasonably in order to recoup some of our reinforcement frequency. By this time, Sniffy is trained to approach the magazine whenever a food pellet is delivered.

The simulation is designed primarily to teach the principles of shaping and partial reinforcement in an operant chamber. The same process was done for the variable ratio 25 as it was for the fixed ratio 25 and extinction followed.
