Does Playing Online Games Make the Brain Stronger? The Surprising Science

Yes, playing online games can make the brain stronger, but like any activity, the devil is in the details. While blanket statements are tempting, the reality is nuanced. Moderation, game choice, and individual predispositions all play a critical role. The emerging consensus among neuroscientists and cognitive psychologists is that certain types of online games, when played in moderation, can demonstrably improve cognitive functions such as attention, memory, spatial reasoning, and problem-solving skills. It’s not about becoming a “genius” overnight, but rather about stimulating neural pathways and encouraging neuroplasticity, the brain’s ability to reorganize itself by forming new neural connections throughout life. However, excessive gaming or the wrong types of games can be detrimental, leading to negative consequences like addiction, social isolation, and physical health problems. So, let’s delve deeper into how gaming impacts the brain, the types of games that offer the most cognitive benefits, and how to strike a healthy balance.

The Upsides: Cognitive Enhancement and Skill Development

Online games, especially those requiring strategic thinking, quick reflexes, and collaboration, provide a unique environment for cognitive training. They challenge players to adapt to rapidly changing scenarios, make split-second decisions, and coordinate actions with others. This constant mental stimulation can lead to several positive outcomes:

Improved Attention and Focus: Many online games demand sustained attention and the ability to filter out distractions. This can translate to improved focus in other areas of life, such as studying or work. Studies using functional MRI brain imaging have demonstrated that children who play video games regularly show higher brain activity in regions associated with attention and memory.
Enhanced Spatial Reasoning: Games involving navigation, map reading, and manipulation of objects in 3D space can boost spatial reasoning skills. This is particularly evident in games like Minecraft and Fortnite, which require players to visualize and manipulate objects in their minds.
Boosted Memory: Strategy games and puzzle games often require players to remember complex information, track resources, and recall past events. This can strengthen both short-term and long-term memory.
Enhanced Problem-Solving Skills: Many online games present players with complex problems that require creative solutions. This can help develop critical thinking and problem-solving skills that are valuable in real-world situations.
Increased Gray Matter: Dr. Manos highlights that gaming, similar to stimulants, can increase gray matter in the brain. Gray matter is vital for interconnectivity, allowing different brain regions to communicate efficiently and improve self-perception.
Improved Emotional Resilience: Gaming can boost mood and create lasting positive effects. It can also be a great way to spend time with friends and relieve stress.

The Downsides: Addiction and Negative Impacts

It’s crucial to acknowledge the potential downsides of excessive gaming. Gaming addiction, also known as Internet Gaming Disorder (IGD), is a real concern that can have serious consequences for mental and physical health. Some of these consequences include:

Addiction and Compulsive Behavior: The dopamine release associated with gaming can be addictive. The brain’s reward system gets activated, leading to a desire to repeat the behavior for the same rush of pleasure.
Social Isolation: Spending too much time gaming can lead to social isolation and difficulty forming meaningful relationships.
Physical Health Problems: Excessive gaming can contribute to physical health problems such as eye strain, carpal tunnel syndrome, and obesity.
Mental Health Issues: Studies have linked excessive gaming to increased rates of anxiety, depression, and sleep disturbances.
ADHD and Gaming: Although Internet gaming disorder is associated with ADHD, serious video games designed for health or educational purposes can actually improve ADHD symptoms and aid in treatment adherence.

Finding the Right Balance: Moderation and Game Choice

The key to harnessing the benefits of online games while minimizing the risks lies in moderation and game choice.

Set Time Limits: Establishing clear time limits for gaming is crucial, especially for children and adolescents. The American Academy of Pediatrics recommends no more than 60 minutes on school days and 2 hours on non-school days for kids over the age of 6. Kids under 6 should spend closer to 30 minutes. It is important to take regular breaks.
Choose Games Wisely: Not all games are created equal. Opt for games that challenge cognitive skills, promote collaboration, and encourage creativity. Avoid games with excessive violence or addictive elements. Consider games that fall under “serious games”. A research study found that action video game players had increased grey matter, which means an action-packed game could be more beneficial than others.
Balance Gaming with Other Activities: Ensure that gaming is balanced with other activities such as physical exercise, social interaction, and hobbies.
Be Mindful of Your Motivations: Are you gaming to relax and unwind, or are you using it to escape from problems? Be aware of your motivations and seek help if you feel like you’re losing control.

Frequently Asked Questions (FAQs)

Here are 15 frequently asked questions to provide further clarity on the relationship between online gaming and brain health:

Can online games really increase IQ? Some studies suggest that certain types of video games can lead to a modest increase in IQ, particularly in children. However, this is likely due to the cognitive stimulation provided by the games, rather than a permanent increase in overall intelligence. The impact is more pronounced than watching TV or using social media.
What types of games are best for brain training? Strategy games, puzzle games, and action games that require quick thinking and problem-solving are generally considered the most beneficial for cognitive function. Games like StarCraft, Civilization, Portal, and even some action-packed games can stimulate the brain in positive ways.
How many hours of gaming is too much? There’s no magic number, but most experts agree that exceeding 2-3 hours per day can be detrimental, especially for children and adolescents. An Oxford study indicates that more than 21 hours every week can have a detrimental impact.
Is it possible to be addicted to video games? Yes, gaming addiction is a real and recognized condition. If you find yourself unable to control your gaming habits, neglecting other important areas of your life, or experiencing withdrawal symptoms when you try to stop, you may be addicted.
Are some people naturally better at video games than others? Yes, genetics and innate abilities play a role. Faster reaction time, hand-eye coordination, and decision-making skills are all key factors that can influence gaming performance.
Do video games improve focus and attention? Certain types of video games can improve focus and attention by training the brain to filter out distractions and maintain sustained attention.
What is the average IQ for a gamer? The average IQ for gamers varies depending on the type of games they play and their preferred platform. PC gamers tend to have the highest average IQ, followed by PlayStation users.
Do gamers have faster reflexes? Yes, studies have shown that gamers, especially those who play action games, often have faster reflexes and improved visual attention compared to non-gamers.
Can video games help with ADHD? Some serious video games designed for health or educational purposes can improve ADHD symptoms and help people stick with treatment. One example is EndeavorRx, a prescription-only game for children with ADHD.
