Penis Envy: As mentioned earlier, this refers to the envy felt by girls during psychosexual development upon realizing they do not have penises.
Identification:In this context, it refers to the process where the girl identifies with her mother in an attempt to possess her father vicariously.
Psychosexual Development: This term again refers back to Freud’s stages of sexual development which includes the phallic stage where both Oedipus and Electra complexes occur.
