The work aims to study the influence of information presentation format and presentation status on cognition and comprehension of digital health information among young adults. A two-factor within-subjects design was adopted in the experiment, where 18 young participants were tested regarding cognitive performance, subjective perceptions and eye movement behavior under two types of presentation status (static and dynamic presentations) and three types of presentation formats (bar graph, instrument graph, and text format). Then, the experimental data were analyzed by repeated measures analysis of variance (ANOVA). The information presentation status significantly influenced users' cognitive performance, and dynamic presentation effectively reduced users' information search time. The presentation format significantly influenced subjective perceptions (such as perceived ease of use and satisfaction), and scores of subjective evaluation of the two graphic presentations were significantly higher than that of the text format. Presentation status and presentation format had significant main effects and interaction effects on eye movement behaviors. There was no significant difference in time to first fixation for bar graph and text format between dynamic and static presentations, while time to first fixation was larger for dynamic instrument graph than for static instrument graph. The two graphic presentations had shorter total fixation duration than that of the text format, indicating higher information cognition efficiency. The dynamic presentation can improve the efficiency in extracting important information, and graphic presentation formats are favored more by users. The findings are of great significance for the understanding of the mechanism of presentation format and presentation status in the cognition of digital health information, and provide implications on optimal design of digital health information.
