This investigation was concerned with whether linguistic competence with printed material is related to the retention of information contained in prose passages of high readability. The specific purpose of the study was to investigate relationships between linguistic competence and free recall, immediate, delayed, and practiced, after the reading of a passage of high readability. In a review of related literature, indications were found that linguistic competence could be expressed by test scores of reading achievement. Therefore, in this study linguistic competence was operationally defined by scores of literal and inferential reading comprehension.

(in English): This thesis is conceived as a metareview of research on differences in perception, understanding and retention of text on various display media. It summarizes the results of the most interesting and most relevant research on this topic conducted since the 80s to the present. Even though it is difficult to summarize the results of individual studies, mainly because of differences in research methodology and differently chosen tested samples, we can say that the main finding of this metareview is that display technologies that are available these days have no negative effect on eye fatigue, reading speed, perception, understanding or retention of text. Theoretical part of this thesis is followed by practical part that consists of three short experiments performed on a small sample of participants. First of those experiments studies differences in reading comprehension and retention among high school students, second experiment focuses on differences in reading speed on different media and subjective evaluation of eye fatigue, and the third experiment is an online form about subjective preferences of study materials among learners.
