In this paper we take a closer and in-depth look at initial results obtained from a previous novel experiment conducted with a 3D subliminal teaching Intelligent Tutoring System. Subliminal priming is a technique used to project information to a learner outside of his perceptual field. Initial results showed great promise by illustrating the positive impact of the subliminal module on the overall emotional state of the learners as well as their learning performances. Indeed, since emotion monitoring is critical in any learning context, we monitored the physiological reactions of the user while they learned and while they answered questions. We present a detailed and precise look at the optimal affective conditions that set the best learners apart. We will also explain a most surprising finding: the positive long term impact of subliminal priming on the entire learning process.
