SNIFFY THE VIRTUAL RAT RESEARCH PAPER

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. It took Sniffy to extinguish the behaviour in approximately three and half minutes. Because the max- reward when he has not expected one.

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.
