Unintended Racism, Depression And Problem Gambling In Elderly Stem From Brain Atrophy

As we age, our brains slowly shrink in volume and weight. This includes significant atrophy within the frontal lobes, the seat of executive functioning. Executive functions include planning, controlling, and inhibiting thought and behavior. In the aging population, an inability to inhibit unwanted thoughts and behavior causes several social behaviors and cognitions to go awry.

In a study appearing in the October issue of Current Directions in Psychological Science, University of Queensland psychologist, Bill von Hippel, reports that decreased inhibitory ability in late adulthood can lead to unintended prejudice, social inappropriateness, depression, and gambling problems.
