Abstract Throughout the past century, several theories of learning have developed in relation to associative learning, which is the most basic learning that there is. There are two types of associative learning: classical conditioning and operant conditioning. Later on in the mid 1900’s, another more advanced mode of learning was studied, that being observational learning. This paper will present an informal learning experience and use the different theories to break down how this learning could have occurred.

She ate all of her food as soon as she received it, because she said that the hamburger “smelled so good”. After her parents paid the bill, they went home to relax. Anna went to bed at her usual time, but woke up in the middle of the night complaining of a stomach ache. The next morning, she became sick to her stomach several times.

She complained about the booth in the restaurant next to her parents’ booth, because all she could smell was the hamburgers they ordered, and she reported that it was making her nauseous. For the next year, Anna would not eat hamburgers and stayed away from the kitchen or grill when
