How the brain responds to reward is linked to socioeconomic background
MIT neuroscientists have discovered that the brain's response to rewarding experiences can be influenced by socioeconomic conditions. In a study of 12 to 14-year-olds from varying socioeconomic backgrounds, the researchers found that children from lower socioeconomic status (SES) backgrounds showed less sensitivity to reward than those from more affluent backgrounds. Using functional magnetic resonance imaging (fMRI), the team measured brain activity as the children played a guessing game with monetary rewards. The results showed that the striatum, a part of the brain associated with reward, lit up more in children from higher SES backgrounds. The findings suggest that lower SES circumstances may cause the brain to adapt by dampening its response to rewards.
