Final Answer:
According to Freud, Janine is suffering from a fixation at the an-al stage of development.
Step-by-step explanation:
Sigmund Freud's psychoanalytic theory posits that personality development occurs in stages, with the an-al stage typically occurring between 18 months and 3 years of age. During this stage, a child experiences pleasure and conflict related to bowel and bladder control. A fixation at the an-al stage can manifest in personality traits such as orderliness, cleanliness, and a strong need for control. Janine's aversion to disorder and reluctance to lend items may be indicative of fixation at this stage, where issues related to control and orderliness are prominent.
It's important to note that Freud's psychoanalytic theory has limitations and is not universally accepted in contemporary psychology. Other perspectives offer alternative explanations for personality development.
