Effect of perceptive enrichment on the efficiency of simulated contexts: Comparing virtual reality and immersive room settings

Abstract

This study was designed within the methodological framework of sensory and consumer sciences, where conventionally internal and external validity are approached separately (e.g. CLT vs HUT). Here is explored the added value of new immersive strategies, such as virtual reality, on their ability to achieve both: internal and external validity. This article presents a comparative study between different experimental setups, involving more than 270 consumers. Two different immersive setups were appraised, simulating the consumption episode ‘eating a sandwich for lunch in a park’: a context room (N = 57) and a VR environment (N = 55). We added two control conditions: a real park in summer (N = 56) and scenario-only in sensory booths (duplicated condition, N1 = 59, N2 = 52). A set of sandwiches were evaluated in a between-participants design, with one duplicated recipe for a reliability assessment. Participants evaluated samples on hedonic criteria and closed the experiment with a questionnaire measuring their level of immersion. After classification of the questionnaire variables, seven underlying dimensions were identified, with significant differences between conditions on the credibility of the environment and the scenario. As expected, with strong external validity, the simulated environments were more immersive than the conventional booth with scenario and less immersive than a real-life environment. Although the immersive conditions did not stand out from the other conditions on the product evaluation performance, all the conditions revealed a high level of internal validity. Mean scores and rankings of the products, participants’ repeatability and discriminatory power remained comparable to the real park environment indices.
