Another research study suggesting that "bigger is better" when it comes to brain size. This studyis unique as it is based on brain autopsies.
Intelligence scholars have had a long-standing interest in this research. I've never paid much attention as I don't see much in the way of practical implications...assessment psychologists are NOT going to start measuring the heads of clients.!!!!!!!! The correlations (proportion of IQ variance explained) is of theoretical/statistical significance, but has little practical significance. But....it is interesting cocktail converstation material.
I find it personally interesting given that my brother (and his friends) used to tease me about the size of my head when I was a kid (they thought mine was too big). Now I have ammunition to fight back!!
I just ran a search of my private reference database. All of the records below make some kind of mention of "brain size" in the article...for those who want to know more...happy reading:)
