Kasanin finds that some forms of sexual delinquency in women may be manifestations of an acting out process by which the individual discharges energies and tensions resulting from repressed conflicts usually involving the father. By demonstrating the irrationality of such behavior, the analyst splits the observing part of the ego from the acting part. He may ameliorate or even completely stop the acting out by timely interpretations of the transference. Three illustrative cases are described. In one of these the patient developed a psychosis which was interpreted as being due to a weak ego's inability to deal with hostility—a situation which the author finds the basis of all forms of acting out.
