Let The Games Begin (But It Matters What Kind)
Exercise is good for brain health; we’ve written about this before, for example:
How To Reduce Your Alzheimer’s Risk ← there are many advices here, but exercise, especially cardiovascular exercise in this case, is an important item on the list!
Today it’s Psychology Sunday though, and we’re going to talk about looking after brain health by means of brain-training, via games.
“Brain-training” gets a lot of hype and flak:
- Hype: do sudoku every day and soon you will have an IQ of 200 and still have a sharp wit at the age of 120
- Flak: brain-training is usually training only one kind of cognitive function, with limited transferability to the rest of life
The reality is somewhere between the two. Brain training really does improve not just outwardly measurable cognitive function, but also internally measurable improvements visible on brain scans, for example:
- Cognitive training modified age-related brain changes in older adults with subjective memory decline
- Functional brain changes associated with cognitive training in healthy older adults: A preliminary ALE meta-analysis
But what about the transferability?
Let us play
This is where game-based brain-training comes in. And, the more complex the game, the better the benefits, because there is more chance of applicability to life, e.g:
- Sudoku: very limited applicability
- Crosswords: language faculties
- Chess: spatial reasoning, critical path analysis, planning, memory, focus (also unlike the previous two, chess tends to be social for most people, and also involve a lot of reading, if one is keen)
- Computer games: wildly varied depending on the game. While an arcade-style “shoot-em-up” may do little for the brain, there is a lot of potential for a lot of much more relevant brain-training in other kinds of games: it could be planning, problem-solving, social dynamics, economics, things that mirror the day-to-day challenges of running a household, even, or a business.
- It’s not that the skills are useful, by the way. Playing “Stardew Valley” will not qualify you to run a real farm, nor will playing “Civilization” qualify you to run a country. But the brain functions used and trained? Those are important.
It becomes easily explicable, then, why these two research reviews with very similar titles got very different results:
- A Game a Day Keeps Cognitive Decline Away? A Systematic Review and Meta-Analysis of Commercially-Available Brain Training Programs in Healthy and Cognitively Impaired Older Adults
- Game-based brain training for improving cognitive function in community-dwelling older adults: A systematic review and meta-regression
The first review found that game-based brain-training had negligible actual use. The “games” they looked at? BrainGymmer, BrainHQ, CogMed, CogniFit, Dakim, Lumosity, and MyBrainTrainer. In other words, made-for-purpose brain-trainers, not actual computer games per se.
The second reviewfound that game-based training was very beneficial. The games they looked at? They didn’t name them, but based on the descriptions, they were actual multiplayer online turn-based computer games, not made-for-purpose brain-trainers.
To summarize the above in few words: multiplayer online turn-based computer games outperform made-for-purpose brain-trainers for cognitive improvement.
Bringing synergy
However, before you order that expensive gaming-chair for marathon gaming sessions (research suggests a tail-off in usefulness after about an hour of continuous gaming per session, by the way), be aware that cognitive training and (physical) exercise training combined, performed close in time to each other or simultaneously, perform better than the sum of either alone:
See also:
❝Simultaneous training was the most efficacious approach for cognition, followed by sequential combinations and cognitive training alone, and significantly better than physical exercise.
Our findings suggest that simultaneously and sequentially combined interventions are efficacious for promoting cognitive alongside physical health in older adults, and therefore should be preferred over implementation of single-domain training❞
