The influence of cognitive control on presence in virtual environments with various immersion levels

The sense of presence is an important determinant of high-quality interaction with virtual environments. In this study, subjects (N=18) interacted with a virtual scenario having to collect digits in correct numerical order navigating in a virtual space. Presence was measured with a Russian version of ITC-SOPI presence inventory in two virtual environments: a CAVE and a standard computer monitor. Cognitive control was measured with measures of task switching, interference control (Eriksen flanker task, Go-No Go task), attention control (antisaccade task), and working memory (n-back task). In standard monitor environment, presence was related to switching (r=0.57, p<0.05) and attention control (r=-0.69, p<0.01). The ability to change task sets and to control attention is thus important to create the sense of presence in less immersive environments. Cognitive control is less important for the sense of presence in full immersion environments. This study is supported by RFBR, Grant 15-06-08998.
