Affective video and problem solving within a Web-environment

Currently there is a growing interest in Web-based multimedia learning environments, particularly those making use of asynchronous streaming video. This interest motivates renewed attention to properties of video for educational purposes. A typical property of video is its emotion-evoking potential. Research by Isen, Daubman, and Nowicki (1987), Kaufmann and Vosburg (1997) and by Vosburg (1998) on video-evoked positive or negative mood states inspired a research project on the didactical functionality of emotion-evoking video materials in relationship to (educational) problem solving tasks within a Web-based environment. The results show that the video materials that were used in the experiment induced the expected positive or negative mood. Differential effects of positive or negative mood for problem solving tasks, however, were not observed. This outcome is discussed in the context of the findings of the above-mentioned authors

Video outside versus video inside the web: do media setting and image size have an impact on the emotion-evoking potential of video?

To explore the educational potential of video-evoked affective responses in a Web-based environment, the question was raised whether video in a Web-based environment is experienced differently from video in a traditional context. An experiment was conducted that studied the affect-evoking power of video segments in a window on a computer screen compared to presenting the same video materials on a television monitor. The study first demonstrates that affect-evoking power of video exists. Although not always significant, the results who that selected positive and negative video clips induce positive or negative affective responses and mood changes in participants, in a Web-based environment as well as in a television environment. Smaller window sizes, however, may do less well

Can mood-inducing videos affect problem-solving activities in a web-based environment?

The purpose of this study was to examine whether a video-induced positive and negative mood has a differential effect on subsequent problem-solving activities in a web-based environment. The study also examined whether task conditions (task demands) moderated the mood effect. As in traditional experimental mood-effect studies, the affective video materials were not related to the tasks. The results show that affective video clips did impact performance on an insight task but not on a divergent-thinking task. This provides evidence that in some cases affective video has an effect on the performance of unrelated tasks in a web-based environment.\ud \u

Flaming on YouTube

In this explorative study, flaming on YouTube was studied using surveys of YouTube users. Flaming is defined as displaying hostility by insulting, swearing or using otherwise offensive language. Three general conclusions were drawn. First, although many users said that they themselves do not flame, flaming appears to be very common on YouTube. Second, views on flaming varied but were more often negative than positive. Some people refrain from uploading videos as a result of flaming, but most users do not think of flaming as a problem for themselves. Third, several explanations of flaming were found to be plausible, among which were perceived flaming norms and the reduced awareness of other people’s feelings. Although some YouTube users flame for entertainment, flaming is more often intended to express disagreement or as a response to a perceived offense by others

Added value of an autostereoscopic multiview 3-D display for advertising in a public environment

The rapid development of new media has made it increasingly possible to present people with ever richer experiences. The two experiments in this paper examine the mediating role of presence in a 3-D display as compared to a 2-D display with respect to commercials in a public environment. The results show that an autostereoscopic multiview 3-D display enhances the feelings of presence and produces a more positive brand attitude. Hence, autostereoscopic 3-D displays outperform 2-D displays for eye-catching out-door advertising
