Sustained inattentional blindness in virtual reality and under conventional laboratory conditions

Virtual reality (VR) might increase the ecological validity of psychological studies as it allows submerging into real-life experiences under controlled laboratory conditions. We intended to provide empirical evidence for this claim at the example of the famous invisible gorilla paradigm (Simons and Chabris in Perception, 28(9), 1059–1074, 1999). To this end, we confronted one group of participants with a conventional 2D-video of two teams passing basketballs. To the second group of participants, we presented the same stimulus material as a 3D360°-VR-video and to a third group as a 2D360°-VR-video. Replicating the original findings, in the video condition, only ~ 30% of the participants noticed the gorilla. However, in both VR-conditions, the detection rate was increased to ~ 70%. The illusion of spatial proximity in VR enhances the salience of the gorilla, thereby enhancing the noticing rate. VR mimics the perceptual characteristics of the real world and provides a useful tool for psychological studies.
