Research has also shown blue light can increase alertness and influence brain areas tied to reward and motivation by stimulating the neural circuits involved in anticipation and decision-making. In the case of gambling, this heightened arousal might dampen our natural aversion to loss, even when the odds are stacked against us., In gambling environments, red light combined with casino‑style sounds has been shown to eliminate the usual cognitive slowdown after losses during decision-making tasks, leading players to make , ScienceAlert reports: Casino lighting could be nudging gamblers to be more reckless with their money, according to a new study, which found a link between blue-enriched light and riskier gambling behavior. The extra blue light emitted by casino decor and LED screens seems to trigger certain switch, “But under bright, blue-heavy light such as that seen in casino machines, the $100 loss didn’t appear to feel as bad, so people were more willing to take the risk.” The study suggests that blue light alters neural processing in brain regions tied to reward and decision-making, such as the amygdala and habenula, possibly dampening negative , The findings, published today in Journal of Neuroscience, the journal from the Society for Neuroscience, suggest that sensory features in casinos may directly influence a player’s decisions and encourage riskier choices—raising new concerns that these features may promote problem gambling., .
