VR based cue-exposure booster sessions The cue-exposure procedure used in this study is an adaptation of the cue-exposure treatment for BN proposed by Martinez-Mallen et al. (2007). Exposure sessions will be conducted individually in a quiet, darkened room. In each session, the participant will sit in front of a 3D laptop with software that is capable of creating a stereoscopic effect that is duly processed by polarized glasses. Headphones with active noise cancellation will also be used to expose the participant to the auditory stimuli in the virtual environments and, at the same time, to isolate the patient from external noises. Participants can interact within the virtual environments in real time. They can move around the scenarios, sit at a table, and they can handle foods displayed using the keyboard and the laptop's mouse.
