As part of the AUDICTIVE priority program, the overall objective of the ECoClass-VR project is to investigate the cognitive behavior of children in virtual, but close to real-life settings. In the first stage of this project, three validated paradigms focusing on different aspects of auditory cognition are examined and extended towards using virtual reality (VR). The paradigm presented in this paper is concerned with the intentional switching of auditory selective attention. Although auditory selective attention (ASA) has been thoroughly investigated in previous work, the influence of audiovisual representations and virtual reality on cognitive performance is of great interest. Therefore, this study presents an audiovisual, child-appropriate approach for investigating the intentional switching of auditory selective attention in a virtual classroom setting using a head-mounted display (HMD).
