Diminishing Loss Sensitivity During Risky Decision-Making in Male Individuals with Gambling Disorder

This study examined 100 men with gambling disorder and 59 healthy controls using the Balloon Analog Risk Task and found that individuals with gambling disorder show paradoxical stronger initial loss aversion but faster decline in loss sensitivity over time. The faster-diminishing loss sensitivity was identified as a key cognitive mechanism explaining impaired risky decision-making in gambling disorder, alongside overconfident beliefs and elevated impulsiveness.
