A new study suggests that the amount of time adolescents spend playing video games does not inherently predict cognitive harm, but rather that signs of behavioral addiction are the true indicators of cognitive difficulties. By separating the effects of heavy gaming from compulsive gaming, the research provides evidence that simply playing for long hours is linked to certain cognitive benefits, while feeling unable to stop playing is associated with lower cognitive performance. The findings were recently published in the journal Computers in Human Behavior.
Scientific literature on video games frequently presents a contradiction regarding their impact on youth. Some studies suggest that gaming is associated with poorer school performance and sleep problems, while other research highlights potential benefits for attention and spatial thinking. The research team was led by scientists from the Karl Landsteiner University of Health Sciences in Austria, in collaboration with the Educational Information Centre in St. Pölten.
The authors theorized that this discrepancy in the research exists because previous studies often grouped all heavy gamers into a single category. By doing so, they combined individuals who simply spend a lot of time playing games with those who exhibit signs of Internet Gaming Disorder. Internet Gaming Disorder is a psychiatric condition characterized by a loss of control, intense cravings, and a continuation of gaming despite negative real-world consequences.
When enthusiasm is not separated from addiction, the distinct relationships that each behavior has with cognitive development can become masked. The researchers referenced a theoretical framework suggesting that initial gaming is an adaptive way for people to regulate their moods and find psychological rewards. However, for some individuals, this behavior shifts from a goal-oriented hobby into a compulsive habit driven by cravings.
To address this ambiguity, the researchers set out to untangle how daily gaming duration and the severity of gaming addiction independently relate to the mental and physical skills of teenagers. They also wanted to see if the specific types of games young people play might play a role in their cognitive development.
The authors gathered data from 3,854 adolescents between the ages of 12 and 16, with an average age of 13.5 years. The sample was nearly evenly split by gender, comprising 47.4 percent girls. The participants were recruited through a vocational information center in Austria. Each teenager provided demographic information and answered questions about their gaming habits, including their average daily gaming time in minutes.
To measure the severity of potential gaming addiction, the participants completed a widely recognized questionnaire designed to evaluate symptoms of Internet Gaming Disorder over the past year. They also indicated their preferred game genres from a provided list and wrote down the name of their current favorite video game. The researchers mapped these free-text answers to specific game franchises for analysis.
Instead of relying on self-reported estimates of intelligence, the scientists used a standardized, computer-based battery of tests to evaluate cognitive abilities. This assessment used an adaptive design, meaning the difficulty of the questions adjusted based on the participant’s performance. The tests measured logical reasoning, verbal comprehension, numerical skills, visual-spatial ability, and long-term memory. Visual-spatial ability refers to the capacity to mentally rotate and manipulate objects in one’s mind.
The researchers also measured motor abilities and information processing using a specialized hardware device. This equipment recorded tapping speed, fine and gross finger dexterity, and the number of errors participants made when asked to respond rapidly to visual and auditory stimuli under pressure. For example, dexterity was measured by how quickly participants could place small pins into designated holes, while hand guidance was measured by tracking errors during a tracing task.
To analyze this large dataset, the team used a statistical technique known as structural equation modeling. This method allowed them to look at the relationships between multiple variables at the same time. By using this approach, they could isolate the specific association of gaming time while mathematically removing the influence of gaming addiction, and vice versa.
The analysis revealed that gaming time and gaming addiction share a strong relationship, but they have completely opposite associations with cognitive performance. Internet Gaming Disorder severity was consistently associated with lower performance across all five measured cognitive domains. Individuals with higher addiction scores also made more errors during the stress-inducing information processing task and showed slightly lower performance in gross finger dexterity.
In contrast, when the researchers adjusted the data to account for the negative effects of addiction, total gaming time showed a positive relationship with several mental skills. Increased daily gaming duration was associated with higher scores in visual-spatial ability, logical reasoning, and long-term memory. The authors noted that if these opposing associations were averaged together, as they often are in epidemiological studies, they would cancel one another out, creating the false illusion that gaming has no effect at all.
“Gaming time alone is too limited as a stand-alone measure,” said David Willinger, a postdoctoral researcher at the Division of Psychological Methodology at Karl Landsteiner University. “A teenager who plays with focus a complex strategy game for many hours does something very different from one who feels unable to stop playing despite negative consequences.”
Willinger added that their analysis highlights the necessity of distinguishing between enthusiastic engagement and problematic behavior. “Our study shows why research has to separate these user patterns more carefully,” he said.
The researchers also found that the types of games the adolescents played mattered significantly. Strategy and role-playing games were associated with better reasoning and verbal skills. Shooter games showed no significant positive associations with cognitive performance and were strongly linked to higher symptoms of Internet Gaming Disorder.
Looking at specific game titles provided even more nuanced insights. Games that emphasize building and exploration, such as Minecraft, were associated with higher verbal and visual-spatial performance. Simulation games with heavy text elements, such as The Sims and Animal Crossing, were also linked to better verbal abilities.
On the other hand, competitive action games like Fortnite and Brawl Stars were associated with lower reasoning and visual-spatial scores, alongside higher rates of gaming addiction. The authors suggest that games featuring continuous progression elements or live services might encourage repeated engagement, pushing players away from deliberate practice and toward dysregulated use. Casual mobile games that require simple swipe gestures, such as Subway Surfers, showed no reliable associations with any of the cognitive domains.
Some notable gender differences also emerged from the data. Girls generally reported lower severity of Internet Gaming Disorder than boys. While girls tended to score slightly lower on certain cognitive tasks, they performed significantly better on fine motor tasks, demonstrating faster finger dexterity and making fewer tracking errors.
The study provides robust data, but the authors noted some limitations and potential misinterpretations. Because the research is cross-sectional, meaning it only captures a single moment in time, it cannot prove cause and effect. It is entirely possible that adolescents who already possess high reasoning skills are naturally drawn to complex strategy games, rather than the games themselves causing an increase in intelligence. Similarly, preexisting cognitive vulnerabilities might predispose certain individuals to develop gaming addictions.
The reliance on self-reported gaming time is another limitation. Adolescents might not accurately remember how much they play, and simple daily averages might fail to capture differences between weekend and weekday habits. Future research could benefit from using objective digital tracking data to measure playtime more accurately.
The scientists also pointed out that they did not measure other factors that could influence cognitive development, such as sleep quality, socioeconomic status, or underlying mental health conditions like depression. Poor sleep is a known side effect of excessive screen time and can independently impair executive functioning and memory.
Additionally, the sample consisted primarily of middle school students from a vocational track. This specific demographic means the findings might not fully apply to the broader adolescent population. Future studies should aim to include a more diverse range of academic backgrounds to see if the patterns hold true.
Finally, the authors suggest that future research should continue to look at specific game mechanics rather than broad genre labels. Modern video games often blend multiple genres, making it difficult to pinpoint exactly which in-game activities relate to specific cognitive changes.
The study, “The tug-of-war between engagement and dysregulation: A comprehensive analysis of cognition and internet gaming disorder in adolescents,” was authored by David Willinger, Sabine Wunderl, and Stefan Stieger.
