Operant Conditioning

This video is a very clear example of Operant Conditioning. Penny is conditioned by Sheldon into behaving the way he wants her to through the chocolates. The chocolates Penny receives when she acts in a way favorable to Sheldon are positive reinforcement. This positive reinforcement causes her to want to repeat the action done to receive the reinforcement in the first place, therefore increasing the frequency of such behavior. Thus showing Operant Conditioning.
