abstract = {A growing body of literature documents how exposure to another person's fear-related body odorants can increase one's own anxiety and interfere with processing of social information, such as facial expression and impression formation. Building on these results, we aimed to 1) test the hypothesis that exposure to fear-related odorant would affect impression formation through fear contagion and 2) verify whether these effects can be observed in an ecologically valid (i.e., virtual) environment. We proposed that exposure to fear-related odorant would cause receivers to feel more anxious, which in turn would lead them to report less trust toward an unknown virtual character. This study had 2 distinct phases. First, we collected perspiration odorants from the armpits of 12 male senders (i.e., the source of the odorant) during the viewing of either fear or joy inducing film clips. In the second phase, 53 women receivers were exposed to either a fear, joy, or neutral odorant (i.e., between-subjects design) by breathing through a gauze attached to a disposable respirator mask while immersed in a virtual bar. As expected, receivers exposed to fear odorants felt significantly more stressed. Mediation analysis also revealed an indirect effect of exposure on trust through anxiety. More specifically, the more anxious the receiver felt, the less she trusted the virtual character. Our results show for the first time that the impact of exposure to fear-related body odorants on negative interpersonal impression formation is mediated by the anxiety induced in the receiver. © 2019 The Author(s) 2019.

abstract = {Smell can increase the sense of presence, reality, and realism when exposed in a virtual environment. This effect has been found to be increased when the nature of the odour is concordant visually with the scene, i.e. exposure to an unpleasant odour in a filthy virtual kitchen. The objective of this project was to verify whether this effect could be generalised to pleasant odours. Participants were immersed in a virtual apartment with a kitchen where the visual scene suggested that cinnamon apple pies had recently been baked. Participants were randomly and blindly assigned to three conditions: exposition to the ambient air, to a pleasant odour of cinnamon apple pie, or an unpleasant odour of urine. The results indicated that while exposure to the visually concordant pleasant odour did increase the sense of reality in a statistically significant manner, it did not affect the sense of presence or realism. Results also suggested that the visual/olfactory concordance may have facilitated the detection of the pleasant odour. The potential implications of the results, potential explanations for the lack of effect on the sense of presence, as well as potential follow-up research projects are discussed. © 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group.},

abstract = {Virtual environments (VE) aim to reproduce life-like experiences, but despite indications that the olfactory sense plays a significant role in everyday life, the integration of olfactory stimuli in VEs is rare. The aim of this paper is to review the literature on olfaction and its potential applications in Virtual Reality (VR). Indications supporting the integration of odorants in VR include the privileged connections between the olfactory system and the brain regions involved in the processing of virtual stimuli used in clinical applications, as well as the interaction between odors, the other senses, and various psychological processes. Presently, smells are mostly integrated in VR applications for post-traumatic stress disorder and drug addiction, but further uses of odorants in VEs could include pain distraction, various training scenarios, such as emergency response and relaxation, and investigations of multi-sensory integration. ©Virtual Reality Medical Institute.},
