Animations presented at different speed are assumed to differentially interact with learners’ perception and cognition due to the constraints imposed by learners’ limited sensitivity to incoming dynamic information. To investigate the effects of high and low presentation speed of animation, two studies were conducted. In Study 1, participants were 55 students who learned about the functioning of a four-stroke engine from an animation with user-controlled presentation speed. In Study 2, eye movements of 19 students were analysed for different system-controlled presentation speeds of animation. Results indicated that high presentation speeds accentuated global events (i.e., macro-events), whereas low speeds accentuated local events (i.e., micro-events). However, eye movements were primarily affected by the content rather than the presentation speed of animation. 相似文献

Differentiates items on a continuum of verbal texts as: books (single-author, small-team, multiple-author, encyclopedias); periodicals (journals, bulletins, bibliographic volume indexes, cumulations); databases. The requirements of their indexing, with varying problems of policy, language, depth, authors' names, and titles, in both printed and electronic form, are discussed. 相似文献

In many countries, studies show declining levels of trust in news media at large. However, there still is no valid and accepted measure of generalized trust in news media. To establish and test a suitable measure, we chose two elaborate scales of related concepts: the scale on trust in media coverage of a specific topic by Kohring and Matthes and a credibility scale by Yale, Jensen, Carcioppolo, Sun, and Liu. We adapted both to measure generalized trust in news media and conducted a survey in Germany to (a) evaluate the dimensional structures of both adapted scales and (b) analyze their predictive validity by testing their explanative power on alternative media use. Both adapted scales yield well-fitting models but should be carefully treated with respect to discriminant validity. The adapted Kohring and Matthes scale successfully predicts alternative media use and can therefore be recommended for further research on generalized trust in news media. 相似文献
