Does multisensory stimulation with virtual reality (VR) and smell improve learning? An educational experience in recall and creativity

Abstract

PurposeThe purpose of this paper is to derive into practical recommendations from multisensory stimulation with virtual reality (VR) and scent to help educators develop effective teaching strategies geared toward aspects of the learning experience, recall, and creativity in a stereotypical learning context.Design/methodology/approachThe paper is based on a randomized experiment in which student participants were subdivided into three treatment groups and one control group. Each group was stimulated by a different combination of visual, auditory, and olfactory stimuli (2D SMELL, VR, and VR SMELL) and the outcomes were compared against those of the control group (2D). Consistent with the Cognitive Theory of Multimedia Learning, hypotheses were constructed to study the effect of different combinations of stimuli on the learning experience and learning outcomes related to recall and creativity in a stereotypical learning context.FindingsTraditional video content alone and bundled with a coherent olfactory stimulus prompted higher self-reported ratings of perceived quality of the sensory experience. Olfactory stimulus in combination with either VR or a traditional video prompted higher self-reported ratings on perceived immersion. In a stereotypical learning context, the highest recall scores were achieved with traditional video alone. Both VR alone and bundled with an olfactory stimulus resulted in enhanced creativity.Research limitations/implicationsThe findings of this study should be interpreted in the context of adopting multisensory stimulations combined with VR technology as part of stereotypical learning contexts. Most professional educators do not have robust knowledge or experience in using build-on-purpose multisensory stimuli but are increasingly engaged in using multisensory tools such as VR, as part of their teaching practice. In relation to recall, the results are consistent with the hypothesis that in a stereotypical learning context, a multisensory experience involving VR and olfactory stimuli can be related to an undesired cognitive load for learners. There exists a possibility that the low-technical version of the VR goggles used, as well as the contents of the instructional video may have influenced the learning outcomes in terms of recall. Hence, future research should consider such aspects and focus on richer learning contexts.Originality/valueThis work offers practical recommendations for instructional design strategies aiming to create multisensory stimulations with VR and olfactory components to foster a richer learning experience and enhanced learning outcomes, under the assumptions of a stereotypical learning context.

iVR-fNIRS: studying brain functions in a fully immersive virtual environment

“…This provides a robust platform to study the integration and interaction of brain processes associated with simultaneously delivered stimulations or tasks. 87 , 88 Past iVR-fNIRS studies have focused on assessing the interaction of cognitive control, visuospatial attention, working memory, and motor functions in scenarios such as distracted driving 57 , 61 and multitask walking 62 to explore the resource demand and brain performance during demanding tasks.…”

Using Mixed Reality Simulation to Improve Junior Medical Trainees’ Preparedness to Manage High-Acuity Trauma

“…These results are well supported in the simulation literature, as MR teaching methods create situated learning experiences where learners can practise interpreting complex interconnected information unfolding in a time-sensitive manner. 19 As junior doctors make up the main body of the emergency care workforce in most tertiary centres, improving the rate at which they can learn skills in information management, decision-making and emergency response could have significant implications for waiting times and patient flow. 6 Moreover, the utility of MR technologies in upskilling the most junior trainees without forfeiting patient safety cannot be overlooked.…”

Can immersive olfactory training serve as an alternative treatment for patients with smell dysfunction?

“… 13 , 14 Recent advances in visual reality technology could potentially be used to enhance the immersivity of the olfactory experience, particularly when implemented in the form of a game 37 and learning task. 38 It is also likely that engaging in activities that involve gustatory and trigeminal perceptions, such as cooking and food preparation, could help patients to regain their olfactory capacity and enjoyment of foods. 39 , 40 Future research could focus on expanding the range of OT tasks incorporating multisensory stimulation aimed at amplifying the immersive experiences.…”
