Abstract
Previous research has implicated alexithymia as a psychological impairment to accurately decode emotional messages. This study attempted to explore potential neurological reasons for this impairment. Using functional brain imaging procedures, an experimental design was undertaken to assess group differences between individuals high and low in alexithymia on brain activation while viewing images of individuals displaying neutral or positive affect. While controlling for activation due to neutral affect images, results showed less activation for alexithymic versus nonalexithymic individuals due to positive affect images in several areas of the brain, including the amygdala and the hippocampus. Several implications and directions for future research are also discussed.
