Davina always needs to stick to the rules no matter what. She also does not like to share and is very careful about how she spends her time and money. A psychoanalytic theorist might suggest that Davina is fixated at the stage of development

A psychoanalytic theorist might suggest that Davina is fixated at the a.nal stage of development.

Explanation:

According to Sigmund Freud, the a.nal stage is the second stage in a child's development. It starts at the age of 18 months and lasts until the age of 3 years. This is when the child achieves a sense of accomplishment and independence for learning how to control their bladder and bowel movements. In other words, they learn how to use the toilet.

However, it is possible for an adult to stay fixated (or stuck) in this stage, according to Freud's theory. If a child does not get over this stage and does not move to the next one successfully, that child will grow to be an adult with issues such as extreme need to organize, to follow rules, to pay attention to details, etc. In other words, he or she will plan out every single detail of their lives and will not leave room for spontaneity or impulsiveness. This seems to be the case with Davina.

It is important to add that the complete opposite can also happen. A person fixated on the a.nal stage can also become extremely disorganized. It will all depend on how potty training was carried out by the parents.

NOTE: I had to type "a.nal" like this because otherwise will not let me post the answer. This can be considered a bad word, so it is understandable. Just remove the dot in the word, and it will be fine.
