Study Notes
Video Game Impact on the Brain
- Global video game usage is substantial: billions of hours are spent weekly.
- US video game participation is high: over 150 million people play regularly (at least 3 hours/week). Average age is 35, with majority aged 18+.
- Parental perception: 71% of parents view video games as positively impacting their children.
- 2016 Video Game Industry Sales: Over $24.5 billion, increasing from prior years.
- Top 3 2016 Video Games (genres): Call of Duty: Infinite Warfare, Battlefield 1, and Grand Theft Auto V (first-person shooter/action-adventure). These genres accounted for 27.5% and 22.5% of game sales in 2016 respectively
Video Games and Brain Changes
- Effect on brain & behavior is supported by research: 116 studies reviewed to evaluate impact.
- Gaming effects go beyond simple opinions (often praised or demonized without data).
- Impact on brain structure and function are observed: 22 studies on structural changes; 100 studies on functional changes.
- Positive impact on attention: Improvements in sustained/selective attention. Enhanced brain regions/efficiency in managing focused attention.
- Improved visuospatial skills: Increased size/competence of related brain regions. Right hippocampus enlargements observed in long-term gamers and those in training.
- Gaming addiction (Internet Gaming Disorder) identified: Alterations in the reward system/neural pathways (pleasure, learning, motivation). Changes are visible in gamers exposed to cues that increase cravings, and their brain response during exposure exhibits characteristics seen in other addictions.
- Note: brain responses to gaming don't always indicate consequential changes in real-life behavior. Further study is needed to identify specific effects and their causes.
