"An important point to emphasize is that it is necessary for attentional resources to be directed to stimulus information before the sense of presence can occur."

"Through the interconnections of the populations of neurons that were active during the original experience, a partial multimodal reenactment of the experience is produced. Critical for such an account, one reason that only parts of the original neural states are reactivated is that attention is selectively focused on the aspects of the experience that are the most salient and important for the individual. [...] Because emotions are salient and functional, this aspect of experience will certainly be preserved."

"We can think of presence as a selector among environments to which to respond, which operates dynamically from moment to moment [...] A fundamental proposal of this paper is that the set of stimuli of the
present environment forms an overall gestalt, providing a consistent believable world in itself."

Presence in a VE does not require completely shifting attention from the physical environment to the VE and humans can experience varying degrees of presence in different environments. The allocation of attentional resources plays a part in the development of presence but is not the whole story.
"experiencing presence [...] requires the ability to focus on one meaningfully coherent set of stimuli (in the VE) to the exclusion of unrelated stimuli (in the physical location) [...] Though novel aspects of the VE may attract some attention, presence depends less on their novelty than on how well they are connected within the entire VE stimulus set."
