Academic mobility is a life experience in which a lot of young people participate and experience that affects the lives and characteristics of its participants in different ways. The aim of the research was to examine certain characteristics of the participants of academic mobility and to compare them with a comparable group of participants without the experience of academic mobility. The examined characteristics refer to multicultural personality traits, cognitive flexibility and actively open-minded thinking. The selected characteristics have been shown to be important for functioning in a multicultural context, but they can also develop in a multicultural context. The survey was conducted with 352 participants in the final sample. Inventory used in this online research was the Multicultural Personality Inventory – 34 (Fietzer and Ponterotto, 2022), more specifically its subscales of tendency for social justice and activism, tendency for friendship with members of different cultures and closeness with people of different sexual orientations. Furthermore, TIPI (Ten-Item Personality Inventory; Gosling et al., 2003), Cognitive flexibility scale (Martin and Rubin, 1995), Actively Open-Minded Thinking Scale (AOT; Stanovich and Toplak, 2023) and a questionnaire on sociodemographic data were also used during the study. The results showed that the participants of academic mobility have significantly more pronounced multicultural personality traits. More precisely, they have a more pronounced tendency for social justice and activism, as well as a tendency and closeness to people of different cultures or sexual orientations compared to young people without experience of academic mobility. Between the comparable group and the participants of academic mobility, no statistically significant difference was found in cognitive flexibility or actively open-minded thinking. The results are discussed taking into account the limitations of the research and their contribution to the understanding of the characteristics of academic mobility participants.
