This paper discusses novel research conducted to study the direct impact of learner’s affective changes on the value of a well established EEG-mental engagement index. An acquisition protocol for recording the electrical activity of the human brain, known as electroencephalography or EEG, was implemented in a learning environment specifically constructed(More)
In this paper, we discuss the use of physiological data for quasi real-time adaptation in ITS. We present preliminary results where we analyze learners’ reactions while using a game-like virtual learning environment. We also discuss the relevance of adding cerebral data to adaptation by the means of an electroencephalogram.
This paper presents results from an empirical study conducted with a novel subliminal teaching technique aimed at enhancing learners performance in an ITS. We replicated previous findings with the same technique but in a 2D environment. Non intrusive physiological sensors were used to record affective and cerebral responses. A brain analysis technique(More)
Current Intelligent Tutoring Systems (ITS) employ explicit and direct learning strategies when interacting with learners. Although these ITS use cognitive and logical models to analyze the conscious cognitive processes behind reasoning, we believe that in specific situations during knowledge acquisition, such as reasoning, unconscious cognitive processes(More)
Emotions play an important role in cognitive processes and specially in learning tasks. Online learning is no exception. Detecting a learner’s emotional reaction for a given situation is an essential element for every Distant Learning Environment. Nevertheless, inferring a learner’s emotional reaction in those environments is not a trivial task. In this(More)
This paper presents results from an empirical study conducted with a subliminal teaching technique aimed at enhancing learner’s performance in Intelligent Systems through the use of physiological sensors. This technique uses carefully designed subliminal cues (positive) and miscues (negative) and projects them under the learner’s perceptual visual(More)
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(More)
This study investigates Serious Games (SG) to assess motivational factors appropriate to an Intelligent Tutoring System (ITS). An ITS can benefit from SG’ elements that can highly support learners’ motivation. Thus, identifying and assessing the effect that these factors may have on learners is a crucial step before attempting to integrate them into an ITS.(More)
Recent works in Computer Science, Neurosciences, Education, and Psychology have shown that emotions play an important role in learning. Learner’s cognitive ability depends on his emotions. We will point out the role of emotions in learning, distinguishing the different types and models of emotions which have been considered until now. We will address an(More)
Learning a foreign language is often a fun but difficult task. A variety of commercial and non-commercial products focused on multimedia content claim to being the perfect vocabulary teacher. However, these products take neither care about the individual differences nor the emotional states that occur in the learning process. In fact, each individual learns(More)
