Virtual Reality Effects on Food Intake Game to Decrease Food Intake

Aims: * The first aim was to replicate the pre-exposure effect. This was done by assessing the effect of exposing participants to a puzzle game with real foods compared to real nonfoods on food intake. * The second aim was to investigate the potential of VR for eliciting the pre-exposure effect. This was done by comparing the effect of a VR puzzle game with foods to a VR puzzle game with nonfoods on food intake. * The third aim was to assess the effect of branding in VR on brand responses and the role of emotional responses herein. This was done by comparing a branded virtual puzzle game with foods with a (non-branded) virtual puzzle game with foods. Study design: a randomized 2 (game: real vs virtual) x 2 (product: food vs non-food) between-subjects design lab experiment, the effectiveness of pre-exposure to food in a VR game is tested. A fifth condition was added ("VR x branded food") in order to examine brand effects.
