Final answer:
An adult fixated at the phallic stage may exhibit promiscuity or emotional immaturity.
Step-by-step explanation:
An adult who is fixated at the phallic stage may exhibit certain characteristics and behaviors. According to Freud, the phallic stage occurs between the ages of 3-6 and is marked by a child's recognition of their own body and the differences between boys and girls. During this stage, a child may experience feelings of desire for the opposite-sex parent and jealousy towards the same-sex parent. If this stage is not properly resolved, an individual may become fixated at this stage and exhibit traits such as promiscuity or emotional immaturity as an adult.
