Which term is the process of getting stuck at a particular stage of psychosexual development?

• A. Id
• B. Interjection
• C. Fixation
• D. Narcissistic personality disorder

Answer: (C)

Fixation is the process of getting stuck at a particular stage of psychosexual development. In Freud’s theory, if conflicts at a stage are not resolved—whether the needs were too harshly frustrated or excessively indulged—the libido energy remains focused on that stage. That lingering focus can shape adult behavior and personality, leading to traits associated with that stage. For example, an oral fixation might show up as dependency or preoccupation with oral activities, while other stages would lead to different patterns. The other terms don’t describe this developmental process: the id is a primitive part of the personality driving basic urges, interjection is a defense mechanism where you take in others’ beliefs or attributes, and narcissistic personality disorder is a clinical diagnosis, not a process tied to a single stage of development.
