Case 4: Mary is at WalMart with her father. While they are checking out, Mary begins to demand a candy bar but her father refuses. Not accepting this, she continues to complain and starts screaming that she wants a candy bar. Eventually, her father grabs a candy bar and hands it to Mary, and her tantrum and screaming stop as she eats her candy bar. This pattern of behavior is repeated on subsequent trips to WalMart and even the grocery stores. Is this an example of operant or classical conditioning? Diagram the Case from Mary's perspective. From the perspective of Mary's father - what consequence is he receiving?
