Do Videogames Made to Improve Children’s Mental Health Work?

In a review of 27 different studies, a Johns Hopkins Children’s Center team concludes that some video games created as mental health interventions can be helpful – if modest – tools in improving the mental well-being of children and teens with depression and attention-deficit/hyperactivity disorder (ADHD). They did not significantly help with anxiety, however.

A report on the review of studies from peer-reviewed journals between 2011 and March 20, 2024, was published in JAMA Pediatrics.

An estimated 20% of children and teenagers ages three to 17 in the US have a mental, emotional, developmental or behavioural disorder.

“We found literature that suggests that even doubling the number of paediatric mental health providers still wouldn’t meet the need,” says Barry Bryant, MD, a resident in the Department of Psychiatry and Behavioral Sciences in the Johns Hopkins University School of Medicine and first author of the new study.

In a bid to determine if so-called “gamified digital mental health interventions,” or video games designed to treat mental health conditions, benefited those with anxiety, depression and ADHD, the research team analysed their use in randomised clinical trials for children and adolescents.

Bryant and child and adolescent psychologist Joseph McGuire, PhD, identified 27 such trials from the US and around the world. The studies overall included 2911 participants with about half being boys and half being girls, ages six to 17 years old.

The digital mental health interventions varied in content, but were all created with the intent of treating ADHD, depression and anxiety. For example, for ADHD, some of the games involved racing or splitting attention, which required the user to pay attention to more than one activity to be successful in gameplay. For depression and anxiety, some of the interventions taught psychotherapy-oriented concepts in a game format. All games were conducted on technology platforms, such as computers, tablets, video game consoles and smartphones. The video games are available to users in a variety of ways. Some are available online, while others required access through specific research teams involved in the studies.

The research team’s analysis found that video games designed for patients with ADHD and depression provided a modest reduction (both with an effect size of .28) in symptoms related to ADHD and depression, such as improved ability to sustain attention and decreased sadness, based on participant and family feedback from the studies. (An effect size of .28 is consistent with a smaller effect size, where as in-person interventions often produce moderate [.50] to large [.80] effects.)  By contrast, video games designed for anxiety did not show meaningful benefits (effect size of .07) for reducing anxiety symptoms for participants, based on participant and family feedback.

Researchers also examined factors that led to improved benefit from digital mental health interventions. Specific factors related to video game delivery (i.e., interventions on computers and those with preset time limits) and participants (i.e., studies that involved more boys) were found to positively influence therapeutic effects. Researchers say these findings suggest potential ways to improve upon the current modest symptom benefit.

“While the benefits are still modest, our research shows that we have some novel tools to help improve children’s mental health – particularly for ADHD and depression – that can be relatively accessible to families,” says Joseph McGuire, Ph.D., an author of the study and an associate professor of psychiatry and behavioural sciences in the school of medicine. “So if you are a paediatrician and you’re having trouble getting your paediatric patient into individual mental health care, there could be some gamified mental health interventions that could be nice first steps for children while waiting to start individual therapy.”

The team cautioned that their review did not indicate why certain video game interventions performed better than others. They also note that some of the trials included in the study used reported outcome measures, and the studies did not uniformly examine the same factors which could have influenced the effects of the treatment. Some of the video games included in the studies are not easily accessible to play.

The researchers also noted that while video game addiction and the amount of screen time can be concerns, those children who played the games studied in a structured, time-limited format tended to do best.

Stroke Patients can do Rehab at Home with a Videogame Controller

On By ModernMedia
Hand manipulating a controller.
The Novint Falcon, a desktop robot typically used for video games, can guide users through specific arm motions and track the trajectory of its controller.

For recovering stroke survivors, getting intensive, frequent rehabilitation therapy to help restore fine motor skills can be challenging and expensive.

Now, researchers at NYU Tandon School of Engineering are developing a new technology that could allow stroke patients to undergo rehabilitation exercises at home by tracking their wrist movements through a simple setup: a smartphone strapped to the forearm and a low-cost gaming controller called the Novint Falcon.

The Novint Falcon, a desktop robot typically used for video games, can guide users through specific arm motions and track the trajectory of its controller. But it cannot directly measure the angle of the user’s wrist, which is essential data for therapists providing remote rehabilitation.

In a paper presented at SPIE Smart Structures + Nondestructive Evaluation 2024,  the researchers proposed using the Falcon in tandem with a smartphone’s built-in motion sensors to precisely monitor wrist angles during rehab exercises.

“Patients would strap their phone to their forearm and manipulate this robot,” said Maurizio Porfiri, NYU Tandon Institute Professor and director of its Center for Urban Science + Progress (CUSP), who is the paper’s senior author. “Data from the phone’s inertial sensors can then be combined with the robot’s measurements through machine learning to infer the patient’s wrist angle.”

The researchers collected data from a healthy subject performing tasks with the Falcon while wearing motion sensors on the forearm and hand to capture the true wrist angle. They then trained an algorithm to predict the wrist angles based on the sensor data and Falcon controller movements.

The resulting algorithm could predict wrist angles with over 90% accuracy, a promising initial step toward enabling remote therapy with real-time feedback in the absence of an in-person therapist.

“This technology could allow patients to undergo rehabilitation exercises at home while providing detailed data to therapists remotely assessing their progress,” Roni Barak Ventura, the paper’s lead author who was an NYU Tandon postdoctoral fellow at the time of the study. “It’s a low-cost, user-friendly approach to increasing access to crucial post-stroke care.”

The researchers plan to further refine the algorithm using data from more subjects. Ultimately, they hope the system could help stroke survivors stick to intensive rehab regimens from the comfort of their homes.

This study adds to NYU Tandon’s body of work that aims to improve stroke recovery. In 2022, Researchers from NYU Tandon began collaborating with the FDA to design a regulatory science tool based on biomarkers to objectively assess the efficacy of rehabilitation devices for post-stroke motor recovery and guide their optimal usage. A study from earlier this year unveiled advances in technology that uses implanted brain electrodes to recreate the speaking voice of someone who has lost speech ability, which can be an outcome from stroke.

PhD Research Explores Precarious Balance of Sleep, Light and Sedentarism among Gamers

On By ModernMedia

By Helen Swingler

With frequent and long stints at their computers, the average gamer is a sedentary night owl, often compromising on sleep – especially quality sleep – and being exposed to too much blue light. The topic has been explored in University of Cape Town (UCT) PhD candidate Chadley Kemp’s doctoral thesis, a meaty study of over 70 000 words.

Kemp’s research into habitual gaming activities is supervised by Associate Professor Dale Rae, a sleep researcher and senior lecturer at the Health Through Physical Activity, Lifestyle and Sport Research Centre (HPALS) in the Faculty of Health Sciences.

This work is founded on Kemp’s 2018 research underpinning a master’s in medical science at UCT’s former Department of Exercise Science and Sports Medicine in the Sports Science Institute of South Africa. This was upgraded to a PhD in 2020.

His research (he is an esports and video game enthusiast) explores adult esports players’ sleep, health status, light exposure patterns and physical activity.

“We know that sleep affects mental functioning in general, but we weren’t sure about the extent to which this applied to esports players,” said Kemp.

Framework for healthier gameplay

Kemp’s goal is to produce objective data that will guide the development of a framework aimed at promoting healthier gameplay standards and encouraging policy reform within the esports industry.

The tests they used to assess neurocognitive performance were intended to serve as proxies for certain aspects of esports performance because they tested specific mental skills important to gaming, he added.

“We gathered it would be a useful addition to compel gamers to adopt better sleep and lifestyle behaviour changes if it meant … that their health would improve, and they would benefit from better in-game performance – and get an edge over their competitors!”

Kemp’s focus is not on professional gamers, but what he calls “the missing middle” of the esports community: the amateur and semi-competitive gamers.

“This group doesn’t have the same infrastructure and support as their professional counterparts,” he explained. “But what makes them particularly interesting is the fact that they have to balance their gaming commitments with holding down a job, studies, or juggling family or household commitments.”

Global attraction

Esports are burgeoning across the globe – and not only among competitive gamers but audiences too. Writing in the South African Journal of Sports Medicine, Kemp and his co-authors noted that globally competitive gaming attracts 532 million fans alone, according to statistics released in 2022.

However, his study wasn’t motivated by an influx of gamers presenting themselves with sleep difficulties at Associate Professor Rae’s sleep consultancy, Sleep Science. Rather, it stemmed from a broader observation and concern within the local esports community about gamers and poor-quality and short-duration sleep, high levels of sedentarism, and excessive exposure to artificial or electronic night at night.

Based on these conversations and endorsed by anecdotal evidence from within the esports industry, Kemp said he and Rae were able to determine that sleep curtailment had seemingly become a “rite of passage” among gamers. Primarily, most gaming takes place at night because of gamers’ daytime commitments.

As there wasn’t much literature on the topic (much of it is focused on the implications of gaming in children and adolescents) and most studies were survey-based and didn’t target esports players or those regularly engaged with gaming, there was significant knowledge gap that needed filling. As a demographic, Kemp is particularly interested in adult esports players because of the greater health risks posed by age and unhealthy lifestyle factors, such as smoking and alcohol consumption.

Because he needed a tool to measure sleep and physical activity concurrently, he validated the Actiwatch, a special research device, to do this. The device also measures light exposure. For his sample group, Kemp recruited eligible esports players and measured variables of interest. These were clinical measures (anthropometry, blood pressure, blood markers) and self-report data (questionnaires on sleep, chronotype, daytime sleepiness and gaming addiction) and their cognitive performance.

“We also included non-gamers in our study, so we could compare our gamers against people who were not gamers. In total, we had 59 male participants (31 gamers; 28 non-gamers). (The females volunteering to participate did not meet the study’s inclusion criteria.) For a week, these individuals wore the Actiwatch to track their sleep, physical activity, and light exposure.”

Key findings

The key findings of his research make for interesting reading:

  • esports players have comparable sleep duration to non-gamers (control group) but tend to sleep later than others. They hit the middle of their sleep cycle around 04:08 compared to 03:01 for the control group.
  • A much larger percentage of esports players (45.2%) showed night-oriented habits (or evening chronotypes), ie they are more active and alert at night. This is in contrast to only 7.1% of the control group showing similar evening tendencies.
  • They nap more during the day, but their night sleep duration is similar to that of the control groups.
  • There was no significant difference in risks related to heart diseases or metabolic diseases between the two groups, which Kemp speculates might be related to their young age. But most of the health markers were tentatively raised, which could point to worse cardiometabolic health in future.
  • Esports players smoke more.
  • Esports players performed better in brain-based tasks, showing better attention and accuracy, and making fewer mistakes.
  • Esports players are less active than the control group. They sit more (11.2 vs 9.1 hours a day) and are less physically active, whether it’s moderate- or vigorous-intensity activity.
  • Esports players have specific active and inactive hours. They are less active in the early morning and certain evening hours but are more active around midnight.
  • Esports players are exposed to dimmer light for a more significant part of their day, and their exposure to bright light happens later at night.

This work is important for several reasons, said Kemp. A key takeaway from the research revolves around chronotypes.

“Esports players seem to have sleep patterns that align with being night owls and this may be influenced both by their natural tendencies and their gaming habits. It’s also possible that a genetic disposition and exposure to artificial light from screens collectively contributes to these sleep patterns.

“The combined effect is thought to create a cycle where their preference for evening activities leads to more gaming, which in turn reinforces the night owl tendencies. This impacts on their sleep quality and quantity.”

He added: “Perhaps more obviously, gaming is a massively popular phenomenon that transcends age, sex, and geography. It’s a dominant form of entertainment and its competitive arm, esports, is progressing towards acceptance as a genuine form of sporting competition.”

From the neurocognitive side, it’s clear that gaming can sharpen several cognitive abilities, such as attention and problem-solving.

“However, the catch is, if you’re not getting enough sleep, these enhanced skills could take a hit,” said Kemp. “Gamers might see slower reactions, flawed decision-making, and even a drop in their in-game stamina. So, while gaming certainly has its merits and can even boost certain mental skills, it doesn’t come without health considerations. “

Kemp’s research is aimed at ensuring that anyone engaged with gaming or esports does so in a healthy way.

“The purpose is to create a steppingstone towards health regulation in gaming and esports,” he said. “By creating awareness and providing evidence-based recommendations to prevent chronic health problems caused by unhealthy gaming behaviour, it supports individual decision making, governments, and policy makers. It’s valuable to anyone involved in or impacted by gaming.”

Kemp’s guidelines for gamers:

  • Get between seven and nine hours’ sleep a night and keep a regular sleep schedule (on weekends too).
  • Set fixed waking and sleep times to establish a more robust sleep–wake cycle.
  • For better sleep, ensure your bedroom is dark, quiet, and cool (16-18°C is optimal).
  • Limit the amount of light exposure in the hours before bedtime (including light from phones, laptops, TVs, etc).
  • Limit caffeine to the morning and afternoon. This means no energy drinks during those night-time gaming sessions).

Adults Get the Least Sleep From Their 30s to 50s

On By ModernMedia

People sleep less in mid-adulthood than they do in early and late adulthood, according to a large study published in Nature Communications. The study investigators found that sleep duration declines in early adulthood until age 33, and then picks up again at age 53.

The study, involving 730 187 participants spread over 63 countries, revealed how sleep patterns change across the lifespan, and how they were largely the same across countries.

Study participants were playing the Sea Hero Quest mobile game, a citizen science venture designed for neuroscience research, which was designed to aid Alzheimer’s research by shedding light on differences in spatial navigational abilities. Thus far, over four million people have played Sea Hero Quest, contributing to numerous studies across the project as a whole.

In addition to completing tasks testing navigational ability, anyone playing the game is asked to answer questions about demographic characteristics as well as other questions that can be useful to neuroscience research, such as on sleep patterns.

The researchers, led by Professor Hugo Spiers (UCL Psychology & Language Sciences) and Dr Antoine Coutrot (CNRS, University of Lyon) found that across the study sample, people sleep an average of 7.01 hours per night, with women sleeping 7.5 minutes longer than men on average. They found that the youngest participants in the sample (age 19) slept the most, and sleep duration declined throughout people’s 20s and early 30s before plateauing until their early 50s and increasing again. The pattern, including the newly-identified key time points of age 33 when declining sleep plateaus and 53 for sleep to increase again, was the same for men and women, and across countries and education levels.

The researchers suggest the decline in sleep during mid-life may be from the demands of childcare and working life.

Professor Spiers said: “Previous studies have found associations between age and sleep duration, but ours is the first large study to identify these three distinct phases across the life course. We found that across the globe, people sleep less during mid-adulthood, but average sleep duration varies between regions and between countries.”

People who report sleeping the most are in Eastern European countries such as Albania, Slovakia, Romania and the Czech Republic, reporting 20–40 minutes extra sleep per night and the least in South East Asian countries including the Philippines, Malaysia and Indonesia. People in the United Kingdom reported sleeping slightly less than the average. People tended to sleep a bit less in countries closer to the equator.

The researchers found that navigational ability was unaffected by sleep duration for most of the sample, except for among older adults (aged 54–70) whose optimal sleep duration was seven hours, although they caution that the findings among older adults might be impacted by underlying health conditions.

Arrhythmias From Playing Video Games in Susceptible Children

On By ModernMedia

Video games can precipitate life-threatening cardiac arrhythmias in susceptible children whose predisposition may have been previously unrecognised, according to findings published in Heart Rhythm. The investigators documented an uncommon, but distinct pattern among children who lose consciousness while playing video games – particularly among multiplayer war gaming which can have stressful online interactions.

“Video games may represent a serious risk to some children with arrhythmic conditions; they might be lethal in patients with predisposing, but often previously unrecognized arrhythmic conditions,” explained lead investigator Claire M. Lawley, MBBS, PhD. “Children who suddenly lose consciousness while electronic gaming should be assessed by a heart specialist as this could be the first sign of a serious heart problem.”

The investigators performed a systematic review of literature and initiated a multisite international outreach effort to identify cases of children with sudden loss of consciousness while playing video games. Across the 22 cases found, multiplayer war gaming was the most frequent trigger, and some children died following a cardiac arrest. Subsequent diagnoses of several heart rhythm conditions put the children at continuing risk. Catecholaminergic polymorphic ventricular tachycardia (CPVT) and congenital long QT syndrome (LQTS) types 1 and 2 were the most common underlying causes.

There was a high incidence of potentially relevant genetic variants (63%) among the patients, which has significant implications for their families. In some cases, the investigation led to the diagnosis of familial heart problems. “Families and healthcare teams should think about safety precautions around electronic gaming in children who have a condition where dangerous fast heart rhythms are a risk,” noted Dr Lawley.

Adrenergic stimulation related to the emotionally charged electronic gaming environment was attributed as the pathophysiological basis for this phenomenon. At the time of the cardiac incidents, many of the patients were in excited states, having just won or lost games, or were engaging in conflict with companions.

“We already know that some children have heart conditions that can put them at risk when playing competitive sports, but we were shocked to discover that some patients were having life-threatening blackouts during video gaming,” added co-investigator Christian Turner, MBBS. “Video gaming was something I previously thought would be an alternative ‘safe activity.’ This is a really important discovery. We need to ensure everyone knows how important it is to get checked out when someone has had a blacking out episode in these circumstances.”

The study notes that while this phenomenon is not a common occurrence, it is becoming more prevalent. “Having looked after children with heart rhythm problems for more than 25 years, I was staggered to see how widespread this emerging presentation is, and to find that a number of children had even died from it. All of the collaborators are keen to publicize this phenomenon so our colleagues across the globe can recognize it and protect these children and their families,” noted co-investigator of the study, Jonathan Skinner, MBChB, MD, also from Sydney.

In an accompanying editorial Daniel Sohinki, MD, MSc, and coauthors pointed out that, “exertion should be understood to encompass activities outside of traditional competitive athletics. Appropriate counselling regarding the risks of intense video gameplay should be targeted in children with a pro-arrhythmic cardiac diagnosis, and in any child with a history of exertional syncope of undetermined aetiology. Further, any future screening programs aimed at identifying athletes at risk for malignant arrhythmias should encompass athletes being considered for participation in eSports.”

Video Games Designed for the Elderly Boost Cognition

On By ModernMedia

Scientists have developed a variety of games designed to boost older adults’ cognitive capacity. Co-creator Professor Adam Gazzaley, MD, PhD, said the games can be an “experiential medicine”. The games adapt to the players’ skill on the fly, and were shown to confer benefits on many important cognitive processes such as short-term memory, attention and long-term memory.

Each game uses adaptive closed-loop algorithms that Dr Gazzaley’s lab pioneered in the widely cited 2013 Neuroracer study published in Nature, which first demonstrated it was possible to restore diminished mental faculties in older people with just four weeks of training on a specially designed video game. The most recent game, which uses drumming, is described in in PNAS.

Watch a short video showing how the games Neuroracer and Body Brain Trainer, developed by the Neuroscape Center, improve cognitive function for multitasking and working memory, and can even be beneficial for conditions like ADHD, Parkinson’s, and multiple sclerosis.

These algorithms get better results than commercial games by automatically adjusting in difficulty according to the players’ skills. The games using these algorithms recreate common activities, such as driving, exercising and playing a drum, and use the skills each can engender to retrain cognitive processes that decline with age.

“All of these are taking experiences and delivering them in a very personalised, fun manner, and our brains respond through a process called plasticity,” said Prof Gazzaley at the UCSF Weill Institute for Neurosciences and who is founder and executive director of Neuroscape. “Experiences are a powerful way of changing our brain, and this form of experience allows us to deliver it in a manner that’s very accessible.”

The lab’s most recent invention is a musical rhythm game, developed in consultation with drummer Mickey Hart, that not only taught the 60 to 79-year-old participants how to drum, but also improved their ability to remember faces.

The eight-week program used visual cues to train people how to play a rhythm on an electronic tablet, with an algorithm matching difficulty to the player’s ability. The cues disappeared over time, forcing the players to memorise the rhythmic pattern.

When the participants were tested at the end to see how well they could recognise unfamiliar faces, electroencephalography (EEG) data showed increased activity in a part of the brain on the right side (the superior parietal lobule) that is involved both in sight reading music and in short-term visual memory for other tasks. The researchers said the data indicate that the training improved how people bring something into memory and then take it back out again when they need it.

A second game, the Body Brain Trainer, published recently in NPJ Aging, improved blood pressure, balance and attention in a group of healthy older adults with eight weeks of training, as well as a key signature of attention that declines with age. The game also included a feedback mechanism.

“We had people wearing a heart rate monitor, and we were getting that heart rate data and feeding it into the game,” said Joaquin A. Anguera, PhD, associate professor of neurology at UCSF and director of the Clinical Division at Neuroscape. “If they weren’t working hard enough, the game got harder.”

Neuroscape published the results of a third study last year in Scientific Reports on a virtual reality spatial navigation game called Labyrinth that improved long-term memory in older adults after four weeks of training.

“These are all targeting cognitive control, an ability that is deficient in older adults and that is critical for their quality of life,” Prof Gazzaley said. “These games all have the same underlying adaptive algorithms and approach, but they are using very, very different types of activity. And in all of them we show that you can improve cognitive abilities in this population.”

A Prescription-only Video Game to Treat ADHD in Children

On By ModernMedia
Photo by Emily Wade on Unsplash

Doctors in the US have been prescribing a unique new treatment for attention deficit hyperactivity disorder (ADHD) in children – a video game.

Designed in conjunction with neuroscientists, EndeavorRx, known in clinical trials as AKL-T01, is the first FDA-approved video game designed to treat ADHD in children. It is currently only available in the US by prescription but its creators are hoping to have it approved in other countries.

The game, which involves controlling a little alien racing across different environments to complete tasks, specifically trains users to concentrate on multitasking and to block out distractions – cognitive areas which often need a boost in ADHD.

In a randomised controlled trial published in The Lancet Digital Health, 348 patients, aged 8–12 years old and not receiving medication for ADHD, were randomised to receive the game intervention or a control.

For a control, the clinical trial made use of a different game specifically designed as a digital word game which did not target areas involved with ADHD.

Over four weeks, participants were instructed to play the intervention or placebo game for five minutes, five times a day, five days a week.

The trial found that compliance was high, with 83% of treatment session being played. Treatment-related adverse events were mild and included frustration (5 [3%] of 180) and headache (3 [2%] of 180).

ADHD was measured by Test of Variables of Attention (TOVA) Attention Performance Index (API). The mean change from baseline on the TOVA API was 0·93 in the AKL-T01 group and 0·03 in the control group.

An extension of the trial found that EndeavorRx also worked as an adjunct treatment in children with ADHD who were also receiving stimulant treatment for their condition. One hundred and thirty were enrolled in the On Stimulants cohort, and 76 in the No Stimulants cohort. Despite severe comorbidities being exclusionary, around 20% of the included participants still presented with at least one DSM-listed comorbidity. The trial involved a four week treatment period, a four week pause, and another four week treatment period. Improvements for both groups were found from the first treatment period, and continued into the pause and into the second treatment period, suggesting continuing and lasting gains.

Eddie Martucci, chief executive of Akili which produced the game, told the BBC that EandeavorRx offers something that pharmaceuticals currently cannot. “It is something that’s very difficult to get through molecular means, like taking a pill. But it turns out that sensory stimuli can actually directly stimulate parts of the brain controlling cognitive function.”

MRI Scans of Video Gamers Show Superior Sensorimotor Decision-making

On By ModernMedia

Video gamers who play regularly show superior sensorimotor decision-making skills and enhanced activity in key regions of the brain as compared to non-players, according to a recent US study published in the Neuroimage: Reports journal.

Analysis of functional magnetic resonance imaging (fMRI) scans of video game players suggested that video games could be a useful tool for training in perceptual decision-making, the authors said.

“Video games are played by the overwhelming majority of our youth more than three hours every week, but the beneficial effects on decision-making abilities and the brain are not exactly known,” said lead researcher Mukesh Dhamala, associate professor at Georgia State University.

“Our work provides some answers on that,” Assov Prof Dhamala elaborated. “Video game playing can effectively be used for training – for example, decision-making efficiency training and therapeutic interventions – once the relevant brain networks are identified.”

Assoc Prof Dhamala was the adviser for Tim Jordan, PhD, the paper’s lead author, who had a personal example of how such research could inform the use of video games for training the brain.

Dr Jordan, had weak vision in one eye as a child. As part of a research study when he was about 5, he was asked to cover his good eye and play video games as a way to strengthen the vision in the weak one. Dr Jordan credits video game training with helping him go from legally blind in one eye to building strong capacity for visual processing, allowing him to eventually play lacrosse and paintball. He is now a postdoctoral researcher at UCLA.

The Georgia State research project involved 47 university-aged-age participants, with 28 categorised as regular video game players and 19 as non-players.

The subjects lay inside an fMRI machine with a mirror that let them see a cue immediately followed by a display of moving dots. Participants were asked to press a button in their right or left hand to indicate the direction the dots were moving, or resist pressing either button if there was no directional movement.

Video game players proved to be faster and more accurate with their responses. Analysis of the brain scans found that the differences were associated with enhanced activity in certain parts of the brain.

“These results indicate that video game playing potentially enhances several of the subprocesses for sensation, perception and mapping to action to improve decision-making skills,” the authors wrote. “These findings begin to illuminate how video game playing alters the brain in order to improve task performance and their potential implications for increasing task-specific activity.”

No trade-off was observed between speed and accuracy of response – the video game players were better on both measures.

“This lack of speed-accuracy trade-off would indicate video game playing as a good candidate for cognitive training as it pertains to decision-making,” the authors wrote.

Video Gamers Self-report Feelings of Wellbeing

On By ModernMedia

Volunteers playing video games reported feelings of wellbeing, and video games did not appear to negatively impact players’ wellbeing, a study by the University of Oxford has found.

The researchers sought to investigate the validity of a widespread perception that playing video games may result in addiction and poor mental health. There has been extensive prior research establishing the varying cognitive benefits of playing different types of video games.

The researchers obtained online gameplay statistics from game producers Electronic Arts and Nintendo, then surveyed over 3000 players of two popular games: Animal Crossing: New Horizons and Plants vs Zombies: Battle for Neighborville. These popular games are more ‘relaxed’ than the type of intense action-themed games that often come up in discussions about video games and mental health. 

The surveys queried players on their wellbeing, their motivations and need satisfaction as they played their video games. Each of the volunteers had their gameplay time recorded by the respective game producers. On analysis, the researchers found that players reported slightly more positive responses than expected, with a slight positive correlation between gameplay time and wellbeing.

The researchers stated that the game producers’ only involvement was providing anonymised telemetry data. They also noted that they did not suggest a causal relationship between subjective wellbeing and how much time a person plays video games, only that playing video games does not seem to negatively impact the wellbeing of players.

Instead of considering the amount of time playing, the researchers suggest that the focus should be on why people play games to begin with. The researchers suggest that people who monitor the playing time of others should rather consider if the game is meeting their needs.

A recent, separate study revealed that boys with low physical activity who regularly played video games at 11 had fewer depressive symptoms three years later.
