A research article in the journal "Neuron" argues that it is incorrect to
think of intelligence as being a represented by a single underlying factor,
usually referred to as "g". Instead, it is asserted that "g" is an artifact
of
interacting distinct brain areas engaged in different types of processing.
A press release describing the article is accessible here:

A version of the published article is available on this webpage (lower
right side; look for "Fractionating human intelligence (.pdf)" or click

Though I admit to being partial to this kind of thinking I'd like to point
out two caveats:
(1) Looking at the neuroimaging component and relating it psychometric
performance worries me because such analysis is quite complex and
really requires replication,
and
(2) the researchers are Canadians, eh, which should worry everyone. ;-)
Just trying to get back to normal.
