In this paper, we address depth perception in the peripersonal space within three virtual environments: poor environment (dark room), reduced cues environment (wireframe room), and rich cues environment (a lit textured room). Observers binocularly viewed virtual scenes through a head-mounted display and evaluated the egocentric distance to spheres using visually open-loop pointing tasks. We conducted two different experiments within all three virtual environments. The apparent size of the sphere was held constant in the first experiment and covaried with distance in the second one. The results of the first experiment revealed that observers more accurately estimated depth in the rich virtual environment compared to the visually poor and the wireframe environments. Specifically, observers' pointing errors were small in distances up to 55 cm, and increased with distance once the sphere was further than 55 cm. Individual differences were found in the second experiment. Our results suggest that the quality of virtual environments has an impact on distance estimation within reaching space. Also, manipulating the targets' size cue led to individual differences in depth judgments. Finally, our findings confirm the use of vergence as an absolute distance cue in virtual environments within the arm's reaching space.

AbstractThe neuroscientific study of human navigation has been con-strained by the prerequisite of traditional brain imaging studies that re-quire participants to remain stationary. Such imaging approaches neglect a central component that characterizes navigation -the multisensory ex-perience of self-movement. Navigation by active movement through space combines multisensory perception with internally generated self-motion cues. We investigated the spatial micro genesis during free ambulatory exploration of interactive sparse virtual environments using motion cap-ture synchronized to high resolution electroencephalographic (EEG) data as well psychometric and self-report measures. In such environments, map-like allocentric representations must be constructed out of transient, egocentric first-person perspective 3-D spatial information. Considering individual differences of spatial learning ability, we studied if changes in exploration behavior coincide with spatial learning of an environment. To this end, we analyzed the quality of sketch maps (a description of spatial learning) that were produced after repeated learning trials for differently complex maze environments. We observed significant changes in active exploration behavior from the first to the last exploration of a maze: a decrease in time spent in the maze predicted an increase in subsequent sketch map quality. Furthermore, individual differences in spatial abilities as well as differences in the level of experienced immersion revealed an impact on the quality of spatial learning. Our results demonstrate the feasibility to observe behavioral changes associated with spatial learning, opening the way to the study of cortical dynamics of navigation.

Abstract In the Dynamic Creativity Framework creativity is defined as a context-embedded phenomenon requiring potential originality and effectiveness. This definition indicates that the environmental conditions embedding the creative process have fundamental impact on the process itself and its outcomes. In particular, Virtual environments (VEs) are emerging as everyday contexts for a large part of the world population, affecting behaviors and feelings. VEs have been demonstrated to affect creative performance in several ways, even if the psychological mechanisms at the basis of the different modifications in the creative behavior are far from being completely explained. The aim of this study was to explore the influence of different types of VEs on creative performance, with a specific focus on participants’ emotional reactions and on their individual differences in the Openness personality trait. A total of 22 participants were exposed to four different types of environments: a real room environment (RE), a control virtual environment (CVE) resembling the physical characteristics of the RE, a positive virtual environment (PVE) and a negative virtual environment (NVE). Participants were free to explore each environment for two minutes, then they were asked to perform an Alternative Uses Task for five minutes, to measure divergent thinking performance. Openness and affective reactions in each environment were measured in all participants. Results showed that Openness was associated with higher originality of responses and that this effect was particularly significant in PVE. Importantly, the type of environment interacted significantly with participants’ affective reactions in explaining their creative performance, revealing that an increase of ideas originality was associated with an increase of positive affect, emerging as a consequence of experiencing a PVE. Affective reactions to VEs, in combination with individual differences in term of Openness, thus emerge as one of the possible explicatory mechanisms of the impact of virtual reality on creative performance.

AbstractWe argue that existing data on folk-economic beliefs (FEBs) present challenges to Boyer & Petersen's model. Specifically, the widespread individual variation in endorsement of FEBs casts doubt on the claim that humans are evolutionarily predisposed towards particular economic beliefs. Additionally, the authors' model cannot account for the systematic covariance between certain FEBs, such as those observed in distinct political ideologies.
