Experiences in Virtual Reality: a Window to Autobiographical Memory

摘要

VR-based paradigms could substantially increase the ecological validity of various psychological research topics as VR allows for submerging into real-life experiences under controlled laboratory conditions. In particular, in the field of mnemonic research, concerns have been raised that laboratory memory differs significantly from real-life autobiographical memory. Our study aimed to assess the immersive qualities of VR not only upon application but -more importantly- during the retrieval of the virtual experiences subsequent to a VR session. We presented participants with either a 360 degrees VR or a 2D video of a motorcycle ride followed by an unannounced recognition memory task 48h later. Increased retrieval success and delayed reaction times in the VR group indicate that immersive VR experiences become part of an extensive autobiographical associative network, whereas the conventional video experience remains an isolated episodic event.
