This may lead to cognitive and mental distortions and physiological imbalances, and the appearance of symptoms that cause psychosomatic disorders that are not due to organic physiological imbalances or bacterial diseases, but rather as a result of imbalances in the psychological functions of the ego ,Which increases the symptoms of headache, vomiting, poor digestion, irritable bowel syndrome, shortness of breath, rapid heartbeat, hormonal imbalance, facial redness, and others.Objectives1.Identifying the degree of use of non-consensual psychological defense mechanisms among university students, and the differences in this according to the variable (gender and degree of academic achievement) 1.
