Scent has been well documented as having significant effects on emotion (Alaoui-Ismaili in Physiol Behav 62(4):713-720, 1997; Herz et al. in Motiv Emot 28(4):363-383, 2004), learning (Smith et al. in Percept Mot Skills 74(2):339-343, 1992; Morgan in Percept Mot Skills 83(3)(2):1227-1234, 1996), memory (Herz in Am J Psychol 110(4):489-505, 1997) and task performance (Barker et al. in Percept Mot Skills 97(3)(1):1007-1010, 2003). This paper describes an experiment in which environmentally appropriate scent was presented as an additional sensory modality consistent with other aspects of a virtual environment called DarkCon. Subjects' game play habits were recorded as an additional factor for analysis. Subjects were randomly assigned to receive scent during the VE, and/or afterward during a task of recall of the environment. It was hypothesized that scent presentation during the VE would significantly improve recall, and that subjects who were presented with scent during the recall task, in addition to experiencing the scented VE, would perform the best on the recall task. Skin-conductance was a significant predictor of recall, over and above experimental groups. Finally, it was hypothesized that subjects' game play habits would affect both their behavior in and recall of the environment. Results are encouraging to the use of scent in virtual environments, and directions for future research are discussed.
