So, the degree of development of personality is seen through the marks of others in addition to our own self-perception and self-esteem. The abilities to interact and to correspond the needs of the society define the characteristics of well-socialized personality. According to Freud’s theory, “Personality differences arise from the different ways in which people deal with their fundamental drives” (Freud).

The ability to adaptation in this changeable world characterizes usually a well-developed personality. The adaptation implies the ability to handle stress and to find the way out of difficult situation with the less damage for psychical and physical state and also stands for one of the characteristics of the well-developed personality. The right perception of yourself also indicates a high-level of personality development. Sympathy and understanding the feelings of others become the characteristics of highly developed person. Empathy is a term which stands for the ability to penetrate the inner world of thought and feelings of others and is definitely one of the well-developed person’s indicators. Understanding others can grow into another quality of the well-developed person – altruism. Altruism is a sincere wish to help others without the anticipation of reward. But the characteristics of the well-developed personality can be changed in order to correspond the needs of the environment. Good personality in the family interaction and good personality for the successful business can require completely different characteristics.

Badly developed, the characteristics mentioned above define a low level of personality development or some personality disorders. These people most often have problems with social skills and adaptation in new social surrounding environment and new situations, rapid change of moods, emotional states and have big problems creating and maintaining any kind of the relationships. The problems with the emotional states, their realizations and expressions are often accompanied with the low ability to empathize. There are a lot of other characteristics of social deviant behavior but all they are differentiated the low ability to interact with the other individuals and to correspond the demands of the society. Personality disorders can be expressed as aggression, hyperactivity, depressions, criminal behavior and the inclination to suicide.

Aggression is a big problem which affects a lot of people of the society. The major problem here is that both – the person who expresses aggression and the person to whom the aggression is directed suffer. In many cases the surrounding environment which has to observe the scenes of the aggression suffers also. “Aggression in childhood and adolescents predicts aggression, violence and other anti-social behaviors, such as substance abuse and a criminal record, in adulthood” (Offord and Bennett, 1994). Aggression is defined as any physical or verbal behavior aiming to hurt others. It can take numerous forms and can be difficult to be traced sometimes but being well informed about it we can learn to recognize it in ourselves and in others and learn to manage it to escape stresses and problems. During our life we meet a lot of kinds of aggression. As an example, every day we meet a verbal aggression. “Verbal aggression is message behavior which attacks a person’s self-concept in order to deliver psychological pain.”(Infante, 1995). Another kind of personality disorder named hyperactivity is expressed usually through the difficulty in concentrating attention in one subject, difficulty in emotions controlling and low self-esteem. The root of the disorder in not being able to concentrate attention on the problem for a time required and very small attention span too quick shifts of attention and activities. Hyperactivity can be mostly found in children’s behavior but if not paid necessary attention and as a result of the wrong attitude it can progress and cause a lot of problems in the life of the raised person. Depression is another personality disorder which causes a lot of problems for the individuals and for the society. Depression is defined as an experiencing of the deep sadness, lowered interested to events and surrounding environment and reduction of activity in all spheres. In contrast to normal sadness, depression can give serious harm to mental, physical and physical state.
