Dopamine , the neurotransmitter the brain releases during enjoyable activities such as eating, sex and drugs, is also released during situations where the reward is uncertain.
In fact dopamine release increases particularly during the moments leading up to a potential reward. It likely also plays a role in reinforcing the risk-taking behavior seen in gambling. Studies have shown that the release of dopamine during gambling occurs in brain areas similar to those activated by taking drugs of abuse. In fact, similar to drugs, repeated exposure to gambling and uncertainty produces lasting changes in the human brain.
These reward pathways, similar to those seen in individuals suffering from drug addiction , become hypersensitive. Repeated exposure to gambling and uncertainty can even change how you respond to losing. Counterintuitively, in individuals with a gambling problem, losing money comes to trigger the rewarding release of dopamine almost to the same degree that winning does.
As a result, in problem gamblers, losing sets off the urge to keep playing, rather than the disappointment that might prompt you to walk away, a phenomenon known as chasing losses.
But gambling is more than just winning and losing. It can be a whole immersive environment with an array of flashing lights and sounds. This is particularly true in a busy casino, but even a game or gambling app on a smartphone includes plenty of audio and visual frills to capture your attention. But are they just frills? Studies suggest that these lights and sounds become more attractive and capable of triggering urges to play when they are paired with reward uncertainty.
In particular, win-associated cues — such as jingles that vary in length and size as a function of jackpot size — both increase excitement and lead gamblers to overestimate how often they are winning. Crucially, they can also keep you gambling longer and encourage you to play faster. Since games of chance are set up so the house always has an advantage, a gambler wins infrequently at best.
