to belief, idea, motivation and knowledge. Freud revolves the basis of his stages around these main ideas as well. The result of whether a child completes this stage successfully or becomes fixated has a lot to do with the child's knowledge of their past with their toilet training experience, the motivation they received from the parents during the stage and the child's own belief in how they should react to the situation. Cognitive psychology also focuses on and studies how people perceive, remember and learn their surroundings, environment, and experiences. These are the three main reasons why a child will become either anal-retentive or anal-expulsive after childhood.
