According to Sigmund Freud's Psychoanalytic Theory of Psychosexual Development and personality structure, if an individual exhibits extreme orderliness, stinginess, stubbornness, rigid rule-following, and an intense compulsion to keep everything meticulously organized (Anal Character), this personality profile is considered to be a result of fixation during which specific stage of development?

Freud's Psychosexual Stages

According to Sigmund Freud's theory of psychosexual development, the Anal Stage typically occurs from about 1.5 to 3 years of age, where the primary focus is on bowel and bladder control.

• Anal Retentive Personality: If toilet training is too strict or rigid, fixations occur, leading to adults who are obsessively clean, orderly, stingy, and stubborn.
• Anal Expulsive Personality: In contrast, overly lenient training can lead to messy and disorganized traits.

Therefore, the traits described in the question correspond directly to fixation in the Anal Stage.
