This presentation is about the outcome of the empirical study on video game's effects on implicit and explicit attitudes towards depicted historical events in the short- and long-term on a sample of 148 young adults. We used, as an intervention tool, a serious game Czechoslovakia 38-89: Borderlands that deals with the expulsion of the Sudeten Germans from the former Czechoslovakia after the WWII.
Results showed more negative pretest-posttest explicit attitude changes towards the expulsion on a general level and a specific level compared to the control group. Over the long-term, group differences in attitude change remained significant for the specific level, but not for general one.
We have not observed any effect on implicit attitudes.
