Annette, Kalat does at least partially address both of your questions in his bio psych text. On the first question about sex differences, he cites a source--here's the abstract on Pubmed:
http://www.ncbi.nlm.nih.gov/pubmed/12725764?ordinalpos=2&itool=EntrezSystem2 .PEntrez.Pubmed.Pubmed_ResultsPanel.Pubmed_DefaultReportPanel.Pubmed_RVDocSu m or: http://tinyurl.com/ml2ozx In that study, the conclusion appears to be that males & females have similar amounts of gray matter in the brain, but males have greater amount of white matter. On your second question, Kalat is not as specific, and doesn't cite a source for what he does say, so I'll leave that one to others.
