    Hi,

    There was a report on this in New Scientist recently. I can't remember what
    it said (having read it through my peripheral vision :-)), so I'll dig it
    out. I don't recall much talk of subliminal learning, so much as ability to
    gain information whilst in a relaxed state brought about by focusing on
    something else (TV, music etc.).

    I think their line was more like that weird sensation you get (this may be a
    delusion I don't know) of being able to play a computer game better whilst
    having a conversation with someone else, and concentrating more on the
    conversation. I have found, on occasion, that I"ve managed to get high
    scores whilst talking to someone about something entirely unrelated to the
    game I'm playing (you can tell I work hard at my job can't you!).

    It's probably just a self delusion though, as most pro sports people talk
    about getting into the zone, where they get a kind of tunnel vision, not
    hearing the crowd etc. etc.

    Vincent
