A. Biological Evidence that Men and Women Think Differently

Narrator: This is Science Today. It seems there's a biological basis for the common and often times comic belief that men and women think differently. According to Dr. Larry Cahill of the University of California, Irvine, men and women use different sides of a brain structure called the amygdala to store emotional memories. In his study, Cahill had men and women watch movies and then traced their brain activity using a PET scan.

Cahill: What we are starting to find is that as things get more emotional, men are tending to remember more of the central aspects of the story at the expense of peripheral details, whereas women are tending to remember both a little better. Men seem to have a different pattern. As things get more emotional, they seem to be focusing in like a flashlight beam on the gist of the story more at the expense of details.

Narrator: Cahill says their results are preliminary and more study is needed.

Cahill: What this study essentially does is document that there is this sex-related laterality of function going on, we don't really know much more than that other than this has to be important.
