Brien has a friend who is a mother. Knowing that Brien is taking a psychology course, she asks him what she can expect during the toddler years of her child's development. Using his understanding of Erikson's stages of development, Brien explains to her that her child will pass through a stage called versus shame and doubt as she undergoes potty training.

Autonomy

Explanation:

Erik Erikson was a psychologist who developed a theory of psychosocial development according to which people go through different stages along their lifespan and each stages is formed by a crisis that the individual has to face and solve in order to move to the next one.

The second stage of this theory is called Autonomy vs. Shame and Doubt and it takes place between the ages of 18 months to approximately 3 years. During this stage, toddlers develop a sense of personal control over physical skills (as this is the stage where they undergo potty training) and then they develop a sense of independence.  

Therefore, we can see that Brien's child will pass through a stage called Autonomy versus shame and doubt as she undergoes potty training.
