Overview
In order to explain why some gamblers develop problems, while others do not, researchers have hypothesized that some gamblers may be (a) more sensitive to the potential of winning and/or (b) less sensitive to losses. These concepts are respectively known as reward sensitivity and punishment sensitivity.
Key Points
Research suggests that reward sensitivity and punishment insensitivity may both contribute to the development of gambling problems. In addition, research indicates that these two factors may be related to some of the motivations that people have for gambling, such as gambling for excitement and novelty, to escape, or for social reasons.
White Paper
GREO's white paper, Nuances of the reward system of problem gambling, looks at the history and current status of research surrounding the reward system and problem gambling in Canada. It also examines what future possibilities and limitations exist for problem gambling research in relation to the brain's reward system.
