Final answer:
Little Hans exhibited a strong desire for his mother and jealousy toward his father, which aligns with the Oedipus complex during the phallic stage of psychosexual development, as analyzed by Sigmund Freud.
Step-by-step explanation:
The suggestion that Little Hans was a 'Little Oedipus' stems from Sigmund Freud's analysis of the boy's phobias and fantasies. The clearest piece of evidence supporting this suggestion can be seen in Little Hans's strong desire for his mother and his jealousy toward his father. This directly correlates with the Oedipus complex, where a boy experiences conflict involving a desire for his mother and feelings of rivalry with his father. Little Hans's fear of horses, which Freud interpreted as a symbol of his fear of castration, suggested an underlying castration anxiety tied to his feelings for his mother and aggression toward his father.
This evidence supports the suggestion that Little Hans was experiencing the classic Oedipus complex, as outlined by Freud's theories of psychosexual development during the phallic stage.
