Video gaming researchers have already studied the effects of violent video games on gamers’ behavior. The present study investigated gamers’ non-verbal behavior and short term effects during and shortly after playing violent video games. The research included three main phases: 1) preselecting violent versus non-violent video games; 2) setting-up an experiment with 20 male college students playing a pair of video games (one violent and one nonviolent game) on Nintendo Wii.

Video gaming researchers have already studied the effects of violent video games on gamers’ behavior. The present study investigated gamers’ non-verbal behavior and short term effects during and shortly after playing violent video games. The research included three main phases: 1) preselecting violent versus non-violent video games; 2) setting-up an experiment with 20 male college students playing a pair of video games (one violent and one nonviolent game) on Nintendo Wii. After playing each game, participants’ degree of violence and arousal were measured by using the International Affective Picture System (IAPS) and the results were compared; 3) asking another group of 17 students to distinguish each gamer’s film clips of playing violent versus non-violent video games. While IAPS results showed that gamers’ degree of violence and arousal did not change significantly after a short experience of playing violent video game, gamers’ non-verbal behavior (facial expression) was 78% correctly distinguished by observers. Limitations are reported and further work is proposed. Mostrar menos

Since the end of 2004, when the law decree about accessibility for Brazilian governmental websites came into force, the federal agencies have been struggling to conform to the norms of current law. Discussions about both evaluation and fixing of pages with access barriers are taking place on the mainstream, but little attention has been paid to a feature commonly found on governmental websites: the large amount of information, compared to commercial websites.

Since the end of 2004, when the law decree about accessibility for Brazilian governmental websites came into force, the federal agencies have been struggling to conform to the norms of current law. Discussions about both evaluation and fixing of pages with access barriers are taking place on the mainstream, but little attention has been paid to a feature commonly found on governmental websites: the large amount of information, compared to commercial websites. This work proposes an accessibility planning for websites with both large number of pages and intense daily accesses, carried out through a work model which we call Accessibility Factory. In addition we present the accessibility planning directions for Brazilian Central Bank website as a case study. Mostrar menos
