Milan Begović and Miro Gavran bring novelties to their theatrical texts by turning to gender psychology by depicting male-female relationships. In addition to male-female relationships, these playwrights also deal with a deeper characterization of their female characters, so in their plays they portray women as self-conscious, brave and prone to physical and erotic desires. The aim of this paper was to analyse the psychology of gender in selected plays by the two playwrights. Gender psychology was related to the analysis of partnerships, marital quality and sexuality. Both authors used the themes of marriage, love triangles and adultery in their plays, so these determinants in the plays were analysed from a psychological aspect. According to phycologist John Alan Lee, important determinant of partnerships is prominent styles of love; to phycologist Robert Sternberg triangular love theory and ways of loving, stages of intimate relationships and gender differences in partnerships. In the analysis of marital quality, the emphasis is placed on the types of communication between spouses, the dimensions of loyalty and the way of presenting marital conflicts between partners. The determinant of sexuality is explained by the typology of marital styles related to marital quality.
