Warren Bickel, the director of the Virginia Tech Carilion Research Institute (VTCRI) Addiction Recovery Research Center, and Keith Humphreys, the Esther Ting Memorial Professor in psychiatry and behavioral science at Stanford University, called their colleagues to action in an article published in JAMA Psychiatry, a journal of the American Medical Association.
The brain's orbitofrontal cortex deals with social interactions, including regret, and has been much studied with fMRI and EEG. Using ECoG, which provides more detailed information about brain activity on millisecond timescales and with better resolution, researchers were able to follow the thoughts that swirl through this brain area during a simple betting game. Surprisingly, after placing a bet, gamblers dwell mostly on regret over previous bets, whether won or lost, essentially second-guessing previous decisions.
In-game purchasing systems, such as 'loot boxes', in popular online games resemble gambling and may pose financial risks for vulnerable players, according to gambling psychology researchers at the University of Adelaide.
An editorial published today by Addiction argues that some online games use in-game purchasing systems that disguise or withhold the long-term cost of microtransactions until the player is already financially and psychologically committed. Such purchasing systems push free-to-play online gaming closer to gambling and may present financial risks for vulnerable players.
Consumers who perceive the benefits of large sums of money promised in mass marketing scams (MMS) are more likely to discount the risks and fall prey to perpetrators, according to new research co-authored by the University of Plymouth.
Parents who restrict their children's use of new media technologies may be acting counterproductively in the long run, particularly if they invoke afterschool homework time as the reason. Their children's scholastic achievements at college lag behind the academic performance of same-age peers, a University of Zurich study shows.
A new review published online today in the journal Addiction has compiled the best, most up-to-date source of information on alcohol, tobacco, and illicit drug use and the burden of death and disease. It shows that in 2015 alcohol and tobacco use between them cost the human population more than a quarter of a billion disability-adjusted life years, with illicit drugs costing a further tens of millions.
Spoiling old dogs in their twilight years by retiring them to the sofa and forgiving them their stubbornness or disobedience, doesn't do our four-legged friends any good. Regular brain training and lifelong learning create positive emotions and can slow down mental deterioration in old age. Physical limitations, however, often do not allow the same sort of training as used in young dogs. Cognitive biologists from Vetmeduni Vienna propose computer interaction as a practical alternative.
Research co-authored by Portland State University finance professor Jing Zhao found that the religious beliefs of the population in counties where hedge funds are headquartered influence the riskiness of hedge fund managers' portfolios.
Over time, dice used in playing games have changed in shape and size and evolved with considerations about fairness, chance and probability.
