Here are a few studies (below) that might suggest how experiences of a copy might someday be processed so as to be perceived as "real." I wonder if after some period of time, the original person's brain would rewire? That might mean that the original person might perceive his/her own body as foreign. Hmmm.... could be a problem. :)<o:p></o:p></span></p><p class=MsoNormal><span style='color:black'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:black'>On a related note, is there any evidence that long-time users of Second Life experience such dissociation? And is it possible or likely that as simulation technology improves and becomes widely available, mass dissociation or psychosis might occur? The effect would be increased by using high-res VR with full immersion and at least 180 degrees to avoid peripheral vision artifacts (humans have about 200 degrees vision) and ultra-high-resolution such as <a href="http://www.sensics.com/products/AugmentedReality.php"><span style='color:black'>http://www.sensics.com/products/AugmentedReality.php</span></a> (<span class=apple-style-span>4200x2400</span><span class=apple-converted-space> pixels)</span>.
