Subliminal priming enhances learning in a distant virtual 3D Intelligent Tutoring System

Abstract—In this paper we discuss the use of subliminal priming in a novel way in the context of a 3D virtual tutoring system. Subliminal priming is a technique used to project information to a learner outside of his perceptual field. Subliminal projections have been used in various fields but never in the domain of 3D Intelligent Tutoring Systems. We also monitored the physiological reactions of the user while they learn. We will present the virtual environment and the subliminal module used. The results of this study show that learners do feel motivated to learn in a 3D environment and enjoy the experience even if they hardly have any video gaming experience at all. Furthermore, subliminal priming, even though not consciously perceived by a learner, seems to elicit strong physiological reactions as well as positively impacts performance.
