Protopsaltis, Aristidis (2008): Reading Strategies in Hypertexts and Factors Influencing Hyperlink Selection. In Journal of Educational Multimedia and Hypermedia, 17 (2) pp. 191-213
“Previous work applying cognitive load theory has demonstrated the effect of various text/graphic/narration relations on learning using multimedia material. Other work has looked at how the degree of integration between the text and graphics influences their use. This study set out to look at how the degree of integration between text and graphics interacts with text density, graphic dynamics, and narration to influence visual attention in multimedia instructional material. Eye tracking methodologies were used to explore how visual attentional resources were distributed under these varying conditions. Narration had a clear effect of “pacing” the viewers of the slide show. In addition, both high text density and relevant animation seemed to create high load conditions that favored students relying more heavily on narration, shifting visual attention away from the text and to the graphic.”

Protopsaltis, Aristidis and Bouki, Vassiliki (2008): Does Gender Matter in Hypertext Reading?. In: Proceedings of World Conference on Educational Multimedia, Hypermedia and Telecommunications June 30-July 4, 2008, Vienna, Austria. pp. 1120-1129. Available online
“It has been argued that gender might affect users attitudes towards electronic media and their academic performance. The accuracy of such claims can affect the use of new technologies in leaning. This study examines gender differences in a hypertext environment. The study focuses on text based electronic documents. The study uses the think-aloud method. Forty two participants (30 males & 12 females) read the hypertext and then, all answered the same set of questions. The experimental hypothesis suggests that gender differences on learning, IT literacy, and visuo-spatial abilities might affect hypertext reading. The results show that gender does not influence reading times, comprehension scores, reading strategies, and the amount of visited links. Additionally, coherence, and selection of hyperlink based on their location seem to be equally important for both genders.”

“The effect of gender in academic achievement has often been the focus of research because of its potential implications. However, the Web has modified the way people access and use information. The present study examines the differences between males' and females' reading behaviour in hypertexts. The study focuses on text based electronic documents. Ninety participants (27 females and 63 males) read a hierarchically structured hypertext and answered a set of questions. The study examines some original variables not previously studied comprehensively, such as coherence of transactions, sum of selected hyperlinks, hyperlink location etc. The results show that gender did not significantly affect any of the measured variables. The data consisted of reading times, comprehension scores, coherent links, hyperlink location, sum of hyperlinks, and the sum of read nodes.

“SIGDOC comes from a technical writing tradition, where literature and rhetoric play an important role. Communication is now giving a broader focus, especially as influences come from graphical design, web design, digital sound or digital multimedia. In Lisbon, we expect to discuss this focus of SIGDOC. This is an important transition that is being done, without loosing its identity. In fact, from the revision process the heterogeneity of view point was identified. This is the result of including more participants from multimedia, computer science and graphical design. For the second time, SIGDOC will take place outside the American continent. For the first time it takes places in a non-English speaking country. It is the ideal place to discuss an important issue either for the technical documentation, either for software engineering or for design of communication communities: translation, internationalization, localization, and globalization. Bologna process is transforming and making an authentic revolution in the European university panorama. This may be faced either as a threat or as an opportunity. In this context, the discussion about a curriculum in design of communication is an important step that may be undertaken by the SIGDOC. It is a step that may contribute to its affirmation either in academia or in practitioner context.”

Protopsaltis, Aristidis and Bouki, Vassiliki (2006): The effects of reading goals in hypertext reading. In: ACM 24th International Conference on Design of Communication 2006. pp. 29-34. Available online
“The present study examined the influence of different reading goals on reading in a hypertext environment. The study focused on text based electronic documents. The study was an independent samples design experiment with three different conditions. Ninety participants read the hypertext allocated into three different conditions and then, all answered the same set of questions. The results show that reading goals did not influence reading times, comprehension scores, and amount of visited links. The data also revealed two factors that influence hyperlink selection: coherence, and location.”

Proceedings of World Conference on Educational Multimedia, Hypermedia and Telecommunications June 26-30, 2006, Orlando, Florida, USA. pp. 450-457. Available online
“This paper reports on a study that examines the reading strategies in a hypertext environment. The study focuses on text based hypertexts. The study used the think aloud method to examine readers’ strategies and the factors that influence the selection of hypertext links. The results show that participants used four strategies: serial, serial overview, mixed, and mixed overview. The data also revealed three factors that influence hyperlink selection: coherence, personal interest, and location. Interestingly, the findings showed no significant differences between different reading goals and use of strategy.”

Protopsaltis, Aristidis and Bouki, Vassiliki (2005): Towards a hypertext reading/comprehension model. In: ACM 23rd International Conference on Computer Documentation 2005. pp. 159-166. Available online
“This paper reports on a study that is concerned with the cognitive aspects of reading in a hypertext environment. The study focuses on text based electronic documents. A cognitive model for hypertext document reading proposed in an earlier work is here developed and validated with the use of think aloud protocols. Navigational strategies that readers employ in hypertext reading and hypertext links' selection are also under study. The results indicate that 100% of the task related data correspond to the components of the cognitive model, allowing us to conclude that the proposed model sufficiently describes the cognitive processes involved in hypertext reading. In addition, three navigational strategies are revealed, linear, mixed, and mixed review. The quantitative data show no significant differences between different reading goals on comprehension and on the amount of text read.”
