Timothy:
No doubt you know the literature well in this area, but I don't see how the
Goldberg reference below shows any evidence for sex-based cognitive
differences caused by laterization.
No doubt the literature on laterization is huge. I would be most
appreciative if you could point me towards a couple articles that make a
strong case for significant cognitive differences b/w the sexes in men and
women based on laterization.
thanks, patrick
