Now, let us think scientifically: Changing technology also means that more people are exposed to video games. Many committed gamers play on desktop computers or consoles, but a new breed of casual gamers has emerged, who play on smartphones and tablets at spare moments throughout the day, like their morning commute. So, we know that video games are an increasingly common form of entertainment, but do they have any effect on our brains and behavior? The studies show that playing video games can change how our brains perform, and even their structure. For example, playing video games affects our attention, and some studies found that gamers show improvements in several types of attention, such as sustained attention or selective attention. The brain regions involved in attention are also more efficient in gamers and require less activation to sustain attention on demanding tasks. There is also evidence that video games can increase the size and efficiency of brain regions related to visuospatial skills. For example, the right hippocampus was enlarged in both long-term gamers and volunteers following a video game training program.
Video games can also be addictive, and this kind of addiction is called "Internet gaming disorder." Researchers have found functional and structural changes in the neural reward system in gaming addicts, in part by exposing them to gaming cues that cause cravings and monitoring their neural responses. These neural changes are basically the same as those seen in other addictive disorders.
The top three best-selling video games of 2016 were Call of Duty: Infinite Warfare, Battlefield 1, and Grand Theft Auto V. These games fall into the first-person shooter or action-adventure genres – the top two genres, accounting for 27.5 percent and 22.5 percent of sales, respectively. First-person shooter and action genres often stand accused of stirring aggression and causing violence and addiction.
NOW LET'S TALK ABOUT VIDEO GAMES & BRAIN CHANGES TAKING PLACE:
1) A growing body of evidence, however, shows that video gaming can affect the brain and, furthermore, cause changes in many regions of the brain.
2) Results of the studies indicate that playing video games not only changes how our brains perform but also their structure.
For example, video game use is known to affect attention. The studies included in the review show that video game players display improvements in several types of attention, including sustained attention and selective attention. Furthermore, the regions of the brain that play a role in attention are more efficient in gamers compared with non-gamers, and they require less activation to stay focused on demanding tasks.
3) Evidence also demonstrates that playing video games increases the size and competence of parts of the brain responsible for visuospatial skills – a person’s ability to identify visual and spatial relationships among objects. In long-term gamers and individuals who had volunteered to follow a video game training plan, the right hippocampus was enlarged.
4) In gaming addicts, there are functional and structural alterations in the neural reward system – a group of structures associated with feeling pleasure, learning, and motivation. Exposing video game addicts to game-related cues that cause cravings, and monitoring their brain responses, highlighted these changes – changes that are also seen in other addictive disorders.
ARE BRAIN TRAINING GAMES BENEFICIAL TO HUMANS?
1) People are increasingly under the impression that brain-training apps will safeguard them against memory loss or cognitive disorders. Researchers tested whether playing brain-training games enhanced the working memory of players and thus improved other cognitive abilities, including reasoning, memory, and processing speed – a process scientists call “far transfer.” However, this was not the case.
2) “It’s possible to train people to become very good at tasks that you would normally consider general working memory tasks: memorizing 70, 80, even 100 digits,” explains Neil Charness, professor of psychology and a leading authority on aging and cognition.
3) “But these skills tend to be very specific and not show a lot of transfer. The thing that seniors, in particular, should be concerned about is, if I can get very good at crossword puzzles, is that going to help me remember where my keys are? And the answer is probably no,” he adds.
4)Charness points out that if your goal is to improve cognitive function, then aerobic exercise may help. Some research has found that aerobic activity rather than mental activity enhances the brain.
DOES VIDEO GAMES BOOST YOUR MEMORY?
1) In contrast, a study published in nature found that through the use of a specially designed 3-D video game, cognitive performance could be improved in older adults and some of the adverse effects on the brain associated with aging, reversed.
2) After 12 hours of training over the period of a month, study participants aged between 60 to 85 years improved performance on the game that surpassed that of individuals in their 20s playing the game for the first time. Moreover, two other significant cognitive areas were improved: working memory and sustained attention. These skills were maintained 6 months after completion of their training.
3) A recent study conducted by neurobiologists at the University of California-Irvine (UCI) found that playing 3-D video games could also boost the formation of memories. Participants were allocated to either a group that played video games with a 2-D environment or a 3-D environment. After playing the games for 30 minutes per day for 2 weeks, the students were given memory tests that engaged the brain’s hippocampus.
4) The participants in the 3-D group significantly improved their memory test scores compared with the 2-D group. The 3-D group’s memory performance increased by 12 percent – the same amount that memory performance usually declines by between 45 and 70 years of age.
5) Strategy video games, in particular, have shown promise in improving brain function among older adults and may provide protection against dementia and Alzheimer’s disease.
6) There is evidence to suggest that video games may be a viable treatment for depression and improve memory and mood in adults with mild cognitive impairment.
7) The effect of video games on the brain is a new area of research that will continue to be explored. We may just be scraping the surface of the potential that video games could present in enhancing cognitive ability and preventing cognitive disorders.
