They know a lot and because they do they outperform the bright but less knowledgeable. Behaving intelligently often depend on knowing a lot. Well, as far as anyone knows, no one has ever gone to a doctor complaining that his long-term memory capacity has been exceeded. In another heroic experiment, ordinary subjects viewed 10,000 pictures for a few seconds each, one after the other. Subjects were about 90 per cent accurate, showing they were remembering something about most of the 10,000 pictures.
Human memory is pretty good.
There is however at least one notable exception. The possibility that innate differences in cognitive processes could be significant for later development has been revived by the finding that early difference in measures of infant looking behavior are predictors of subsequent differences in intelligence-test scores. The correlations tend to be small, but this may be due in part to the limited reliability of the infant measures. The word 'talented' and 'gifted' are potentially misleading. Each of them has led users to infer that children and adults can be firmly divided into distinct categories.
