RIBEIRO, Ana  and  MONTEIRO, Luís. Induction affective scenarios virtual reality: assessment of the sensation of presence. Psicol. clin. [online]. 2015, vol.27, n.1, pp. 139-160. ISSN 0103-5665.

Virtual reality (VR) has been used to induce emotions, emotional responses associated with greater ecological validity. The presence, while the experience of "being there" in a given environment mediated, became closely associated with the VR. This study aims to verify, that viewing 3D Affective Induction Scenarios induce a greater sense of presence compared to their counterparts presented with 2D technology. 30 healthy participants observed the 3D Affective Induction Scenarios on both types of display (2D vs. 3D), while simultaneous records were made of Electrodermal Activity and the Heart Rate and at the end of each scenario, we used the dominance scale Self-Assessment Manikin adapted to the presence and Slater-Usoh-Steed Questionnaire as an instrument of self-reported for assessment of sense of presence caused. The overall results of this investigation suggest that 3D Affective Induction Scenarios induces an increased sense of presence, compared to their counterparts presented in 2D technology. We also verified that scenario unpleasant valence provokes greater sensation of presence compared to pleasant and neutral scenarios.
