According to Freud, fixations occur throughout the psychosexual stages due to:A. deprivation of pleasurable experiences associated with each stage. B. overindulgence in pleasurable experiences at a given stage. C. either deprivation or overindulgence in pleasurable experiences at a given stage. D. an optimal amount of pleasurable experiences at each stage.

c. either deprivation or overindulgence in pleasurable experiences at a given stage.

Explanation:

Sigmund Freud is considered the father of Psychoanalysis, an important part of his theory had to do with unconscious desires and how our experiences during childhood have an impact in our future personality.

One of the main concepts of his theory is the concept of fixations, a fixation is a persistent focus of pleasure-seeking energies at an earlier stage of psychosexual development. These fixations occur when an issue or conflict in a psychosexual stage remains unresolved, leaving the individual focused on this stage and unable to move onto the next. Fixations can occur either because the baby/kid didn't have enough pleasurable experiences during one stage or also because the baby/kid had an overindulgence in pleasurable experiences during one stage. When the baby/kid has an optimal amount of pleasurable experiences, he doesn't develop a fixation.

Therefore, fixations occur throughout the psychosexual stages due to either deprivation or overindulgence in pleasurable experiences at a given stage.
