Abstract: In this study, we discuss the results of our research into psychological models of a typical terrorist’s personality as envisaged by young men and women. We offer empirical criteria to establish types and structuredness of psychological models related to terrorists’ personalities; we also outline and designate certain types of models that are based on domination of invariable or situational manifestations of a terrorist’s personality. For each designated type, we disclose its contents and structure as envisaged by young men and women who are leavers of schools, students of technical colleges and an institute from Rostov-on-Don and Taganrog. According to the model type designated on the basis of young men and women’s scores, we have established prevailing reasons to commit a terrorist act and sources to obtain information about terrorists.
