EMOTIONAL MECHANISMS :
REWARD SENSITIVITY:
ILLUSION OF CONTROL:
I think these three are the most common causes with reward sensitivity being the highest among all of them. The reason why I say this is because the reward center of the brain is usually associated with addicted and dependency, if you read about drug of abuse and other things that usually leads to addiction you’ll notice that it is the reward center of the brain that usually leads to addiction and since gambling deals a lot with rewards it increases the chance of dependency.
