1. Shape Sniffy 3 ways.  Each time start with a new Sniffy. 

        1) Let Sniffy alone in the chamber, (run accelerated time) and see how long it takes Sniffy to press the lever. 

        2) Shape Sniffy by giving her ONE reinforcement every 30 seconds independent of behavior.

        3) Shape Sniffy using Skinner's shaping technique. 

2. How long did it take you to get Sniffy to develop a steady state of responding for each method?

Each vertical line is 5 minutes. 

3.  Use Task analysis to describe the methods that you used to shape Sniffy using Method 3

4. After Sniffy has reached a steady state of responding, how long does it take for Sniffy to become extinct?
