The purpose of the study was to check if there are any differences in processing the same block of information presented in different text formats. In Exp.1 we tried to reveal the influence of leading perception channel of a person (audio channel or visual channel) on the effectiveness of processing written and oral texts. Exp. 2 was aimed to study the peculiarities of comprehension and memorising different types of the texts: (1) written text-only, (2) audio-only, (3) written text + infographics, (4) audiotext + infographics, (5) written text + infographics + audiotext. As a result, a hierarchy of information presentation formats was built in terms of the success of their perception and understanding.
