New article about Presence published on Nature!

Maria V. Sanchez-Vives and Mel Slater have published a review article entitled "From Presence to Consciousness through Virtual Reality" on the prestigious journal Nature Neuroscience (ASI impact factor 2003: 27.007).

In this article, the authors argue that presence - the sense of "being there" perceived during the exploration of a virtual environment - is worthy of study by neuroscientists, and that it might aid the study of perception and consciousness.

Charles Tart: Virtual Reality & Altered States of Consciousness

The link between VR and altered states of consciousness is an interesting one. One of the first researchers that have discussed this relationship is Charles Tart. According to Tart, VR can be considered a new technological model of consciousness. In particular, he suggests that "stable patterns, stabilized systems of these internal virtual realities, constitute states of consciousness, our ordinary personality, and multiple personalities"

Of particular interest is Tart's explanation of the feeling of being "present" in a computer-generated world, although in its article he doesn't use the word presence. He suggests that presence emerges from a core psychological pattern which "automatically organizes the rest of experience around itself in a way that further supports the basic pattern". He thinks that this is the same process of perceiving a constellation. A constallation is not "real", because the spatial distribution of visible stars is random. However, once a pattern has organized, it is hard not to perceive it that way.
