Comparing immersive virtual reality and powerpoint as methods for delivering safety training: Impacts on risk perception, learning, and decision making

•Two studies tested the effect of presentation medium on the effectiveness of a safety training.•Presentation medium was manipulated by using PowerPoint or immersive VR for the training.•The material displayed in the two experimental conditions was identical.•Risk perception, learning, and decision making were measured multiple times.•Both studies found no robust evidence for an effect of the presentation medium. In two experimental studies, we compared safety training given via immersive virtual reality with safety training given via PowerPoint in their effects on risk perception, learning, and risky choices. In Study 1, we compared the two methods in a sample of apprentices (N = 53) and also investigated whether participants’ conscientiousness and locus of control moderated the effects of safety training. In Study 1, we found an effect of training method on the change in risk perception in terms of probability judgments and on risky decisions but not on learning. In Study 2 (N = 68), we sought to replicate Study 1 and also tested whether domain-specific risk attitudes affected risk perception and choice. Furthermore, long-term effects of safety training on information recall and risk perception after a 6-month interval were assessed. The effects found in Study 1 could not be replicated in Study 2. Neither study found an interaction between presentation medium and personality. We conclude that the costly procedure of immersive virtual reality (VR) does not seem justified for safety training because the less costly PowerPoint procedure with vivid film scenes did not fare significantly worse with respect to changes in risk perception, learning outcomes, or decision making.
