Put another way: lumosity makes you good and efficient at lumosity, but not anything else.
Transfer learning is a bugbear for neuroscientists as well as ML people, sadly.
I was using one of the leading 'brain training' apps, and they started requiring a subscription so I switched to another app. Despite having a strong performance in the first app, I had quite a weak performance initially in the second app.
In other words, skills aren't even transferable between brain-training apps, let alone into real life applications.
To prevent brain tissue loss one should walk 35km per week, it is one hour daily. And that amount is to stop decline of mental capabilities, one need to increase that amount of exercise or add fasting or weight training to start to regain "younger" brain.
So I am not impressed.
if that helps..
The best research I ever found was a metastudy in Clinical Psychology Review: "Does mindfulness training improve cognitive abilities? A systematic review of neuropsychological findings" concludes that there's enough evidence that further investigation is warranted.
There's also a lot of downstream research (citing articles) from both publications that are worth investigating.
Transferability though, is still an open question. Even in this meta study, the author's admit that certain types of mindfulness training may be beneficial to certain outcomes.
So perhaps you'll be more mindful and less distracted, but you won't be any "smarter."
(And maybe evolution gave us curiosity to save on battery power with the new knowledge it produced!)
So if you play a game over and over, you don't have to actively think as hard to play it? A bit far from a "younger working brain"
tldr: you improve on the tasks you train on, but generalization to other tasks is extremely limited at best
This isn't my first time going to school old. At age 34 I started University but for various reasons dropped out early.
I have to say going to school now even compared to age 34 just 14 years ago is quite different socially and technologically.
Maybe my brain will benefit from all this learning.
I'd be interested in a study where an additional group replaced games/music with walking outside in the natural environment for 1 hr a day. Or since we know "exercise" increases brain mass, what specifically about exercise causes the response. Are the effects additive? Can we exercise, play music and video games for more than 1x the matter growth?
Its worth noting that, from a brief look, the "cognitive training" program looks like a fairly intensive and detailed course, not some brain-app-like game. I don't know if I've seen something similar offered commercially.
...on the other hand It can't (really) hurt much, and the mind is a weird thing :)
