Thanks.
I'm kinda interested in what they have to say about 'high energy use in the brain of a typical person with OCD'. What they mean seems to not be 'typical person' so much as 'idealised average person in OCD group compared to idealised average person in control group'. I wonder who the 'normal control group consisted in? Non patient population or patient population with different disorder?
I'm kinda interested in the notion that the brain differences are sometimes considered to be a CAUSE of the disorder when the brain changes aren't located in the individuals and I'm also interested in what neuro-imaging helps with respect to explanation.
I went to a seminar a while back on neural imaging and explanation. People were fairly good at telling a good explanation from a bad explanation 9where the bad explanations weren't relevant to the issue). What was interesting was that if you added an irrelevant brain imaging fact then people judged the explanation to be better than it was before. People actually seemed to think that adding an irrelevant brain imaging fact turned a bad explanation into a good one. This finding was constant across first year psychology majors, students taking a mid-level neuropsych course both at the beginning and end of the course. The only people who thought the explanations got WORSE for the addition of irrelevant information (which is the right way to look at it) were the neuroscience experts (PhD students and profs).
Freaky, huh.
I wonder what task people are doing when he neuroimaging comes back...
I wonder how much variation there is between the averages if you compare two 'normal' populations?
I wonder how much variation there is if you set the threshold for activity a little higher / lower?
I wonder what the visual effect would be of selecting different colours for levels of activation (and I wonder how colour maps onto areas of activation). Let me guess... The impressive red bit is... High activity? Or is that supposed to be low?
Thanks for the links.
I'll try and access teh journals too at some point.
