Many thanks for replying. I agree with what you say, so have to rephrase my statement. The low functioning in 'normals' I am referring to is in the narrow sphere that savants excel in. I am not quite convinced that the balance of abilities that normal people have, and which savants obviously lack, is enough to explain the degree
of degradation of information retention and recall that normal people 'suffer'. But it may be.
The salient point is not so much the obvious trade off, but more that savant capacity for knowledge would consume more neural real estate than that required for our compensatory emotional skills. Or at least I presume so. Do we have that capacity in addition
to our social and emotional skills, but have it tempered in its effectiveness?
My feeling is that this is indeed the case. But I am no brain expert, hence this dialogue.
