Step-by-step explanation:
Lauren is obsessed with the cleanliness of her room. According to the psychosexual stages of personality development, she is fixated at the an al stage.
During the an al stage of development (1-3 years), children experience pleasure from bowel and bladder control, which leads to conflicts during toilet training. Success in this stage depends on how parents handle the toilet training process. Freud believed that those who are fixated at the an al stage could develop an an al-retentive personality, which is evidenced by a compulsive need for order and neatness, amongst other traits. Lauren's preoccupation with cleanliness is characteristic of this type of fixation.
