Explanation:

According to Sigmund Freud, an individual's personality is developed over the course of his/her childhood through a series of stages which are called psychosexual stages.

At the an al stage, Freud focus on a child's ability to control his/her bladder and bowel movements and the ability to use the toilet at the right time. He believes that parents who respond with care and encouragement to the child during toilet training tends to develop the child into orderly, tidy, and obsessive person.

On the other hand, parents who punish or shame a child for not using toilet appropriately or at the right time tends to develop a child into messy, disorganized and destructive when he/she grows up.
