| Sumario: | Nowadays, computerized forms of psychodiagnostic methods are often produced without providing appropriate psychometric characteristics, or without proving equivalency with conventional forms. Moreover, there exist tests with more than one computerized versions, which are mostly designed differently. Study I focused on the impact of test design. It was found that even simple change of color scheme (light stimuli on dark background vs. dark stimuli on light background) had a significant effect on subjects' performance. Study II examined equivalency of a computerized speeded test, which is broadly used within psychological practitioners in the Czech Republic; this form was found non-equivalent with its conventional counterpart.
