The article is dedicated to solving a relevant problem - the study of the peculiarities of aggressive behavior in adolescents, as well as the relationship between such significant variables as a person's aggressiveness in interpersonal interaction and the style of behavior in a conflict situation. Aggressiveness is a fairly stable characteristic of the personality, due, on the one hand, to psychophysiological characteristics, and on the other hand, it reflects the internal position of the personality and socialization processes. Being connected in a certain way with other characteristics of the personality, aggressiveness significantly affects the formation of the characteristics of the individual's activity and communication. The image of a conflict situation corresponds to all the main indicators and characteristics of ontological reality: it is always correlated with the subject; it is presented in a person's mind in a "folded" form; it mediates and refracts external influences. According to the results of the correlation analysis, significant relationships were identified between the scales: "Resentment" and "Adaptation" (r=-0.328, p≤0.05); "Verbal aggressiveness" and "Adaptation" (r=-0.41, p≤0.01). An inversely proportional statistical relationship was revealed between such a type of behavior in a conflict situation as "Adaptation" and such a form of manifestation of aggression as "Resentment". This suggests that the more often a student uses such a behavior strategy in conflicts as "Adaptation", the less a form of aggression such as "Resentment" (r=-0.328, p≤0.05) is manifested in behavior.
