Summary: This study found that problem gamblers experience more and more severe harms compared to problem gamers, with gamblers more likely to suffer financial and work-related harms, while gamers tend to experience physical harms. Gaming disorder seems to be associated with a less severe profile of harm, primarily related to neglect of personal wellbeing and obligations, compared to problem gambling.

Summary: Both positive and aversive delayed consequences play a crucial role in decision making. While there is extensive research on temporal discounting of positive consequences, the study of aversive consequences is limited. This study evaluated impulsive behavior in spontaneously hypertensive rats (SHR), an animal model of ADHD, and found that choice impulsivity was similar between strains for both positive and aversive consequences. However, SHR exhibited a higher level of impulsive action compared to the control strain.

Summary: The study found that military members score higher in gambling severity compared to civilians, with women in the military being more vulnerable. Active military members have higher scores in Problem Gambling Severity Index, engage more in online gambling, lotteries, electronic gambling machines, and sports betting, and have a much higher rate of suicidal ideation compared to civilians. Additionally, problem gambling scores among military members are associated with suicidal ideation, tobacco use, and substance use problems. The results suggest that military members may be at higher risk for Gambling Disorder due to factors such as limited leisure options and a high propensity for risk taking.

Summary: This commentary challenges the proposals made in Dinardi, Egorov, and Szabo's (2021) opinion paper, specifically questioning the usefulness of the (expanded) interactional model of exercise addiction and the potential misclassification of adaptive patterns of physical exercise as exercise addiction. It also raises broader concerns about conceptualizing maladaptive exercising as an addictive disorder.

Summary: Loss-chasing is a defining feature of gambling disorder. In real gambling contexts, it can be expressed in the decision of when to stop, how much stake to bet, and the speed of play. A large-scale study using player-tracking data found that after winning, players were less likely to stop and increased their stake amount, indicating win-chasing. After losing, players played more quickly, reflecting an urge to continue gambling.

Summary: In gambling, people tend to speed up after losses, while in experimental psychology's behavioral tasks, we often observe a slowing down after errors. This study tested whether perceived control over the outcome would influence response speed after negative outcomes in gambling, and found that the illusion of control did not influence post-loss speeding.

Summary: Brain imaging studies have found that stimulation of the left dorsolateral prefrontal cortex (dlPFC) can modulate brain reactivity to reward-related cues. However, the impact of contextual factors on this modulation effect remains unclear. In this study, researchers tested the effects of high-frequency repetitive transcranial magnetic stimulation (HF-rTMS) on brain reactivity to cues signaling reward availability or unavailability. The results showed that HF-rTMS modulated brain activity in response to game cues, with increases in posterior insula and caudate nucleus activation and a decrease in occipital pole activation. HF-rTMS also increased ventral striatal activity for cues available for betting but had no effect on cues unavailable for betting.

Summary: This study aims to assess the differential capacity of positive and negative urgency in predicting craving and the severity of video gaming-related problems. Results show that craving largely overlaps with the severity of problems; craving for video games is associated with positive urgency but not negative urgency; positive urgency indirectly affects the number of symptoms endorsed through craving, while negative urgency directly affects the number of symptoms endorsed; urgency traits do not interact with craving in predicting the number of symptoms. These findings support the view that craving is a central feature in the emergence of video gaming problems.

Summary: People tend to slow down after committing an error in tasks, but some studies have found that they speed up after losses in gambling situations. This study investigated the factors that determine whether people slow down or speed up after sub-optimal outcomes (error vs. loss). The results showed that control over the outcome played a role in determining the response to sub-optimal outcomes, as participants slowed down after controllable errors but sped up after uncontrollable errors. This effect was observed regardless of whether controllable and uncontrollable errors were intermixed or not.
