Self=Cyberself?

Just thinking about identity and MMO gaming. I came across Wertheim (1999: 250) who critiques the postmodern view of the
cyberself:

Role playing at being a squirriloid or a Klingon, whatever its genuine value, is simply not an identity-changing experience. I can play any number of online characters without suffering fragmentation of my ‘archived’ self. ‘I’ – that is, my ‘self ’ – can play any number of different personae online and off, but that does not mean I become fragmented. In every one of these situations, I am still me, unless I become a true split personality like Sybil.

It makes me wonder if gaming can really change or fragment our 'true' selves.

Narcolepsy and Gaming?

I came across a study which discusses the effects of narcolepsy on neurospsychological testing and driving simulation. The authors state:

There was no correlation between driving performance and neuropsychological test results or ESS Score. Neuropsychological test results did not significantly change in the follow-up. The difficulties encountered by the narcolepsy patient in remaining alert may account for sleep-related motor vehicle accidents. Driving simulator investigations are closely related to real
traffic situations than isolated neuropsychological tests. At the present time the driving simulator seems to be a useful instrument judging driving ability especially in cases with ambiguous neuropsychological results.

this made me wonder how sleep disorders effect gaming; if those with narcolepsy really don't have any measurable cognitive differences than controls, perhaps other factors (present in the driving simulator model) can account for negative effects of narcolepsy. If a gaming model is used, more data like reaction time and attention could be used to correlate with effects of narcolepsy.
