Compulsive gamblers suffer from an optimism bias that modifies their subjective representation of probability and affects their decisions in situations involving high-risk monetary wagers. This is the conclusion drawn by Jean-Claude Dreher's research team at the CNC (Centre de Neurosciences Cognitives, CNRS / Université Claude Bernard Lyon). These findings, published in the May print edition of Psychological Medicine, could help explain and anticipate certain individuals' vulnerability to gambling, and could lead to new therapeutic approaches.
