Nice snark, but one can extract more interesting insights.

"learning deficits observed in healthy older adults are driven by a diminished capacity to represent and use uncertainty to guide learning"

From a Bayesian, or normal machine learning, perspective: older people have collected more evidence about the world, and thus would normally reduce their learning rate, or belief update amount, for best performance. In this example, though, video games represent a different environment, and the older adults have little evidence about them. However, they fail to have a higher learning rate. Looks to me like an evolutionary adaptation that does not work anymore; the environment did not change that quickly before.

To paraphrase: older people learn more slowly, and this parallels the lesser weight of new evidence when you have more accumulated evidence in Bayesian beliefs; or the reduction of learning rate in machine learning systems.




I'm wondering to which extent this effect can be attributed to illusion of competence, i.e. with age some meta learning program in our brains that is concerned with managing novel data simply becomes lazy because (1) adults really are able to handle most of the situations they are confronted with and (2) they are also expected to be able to deal with any situation. That might simply lead to a detoriation of the sort of novelty detection. Adults tend to automatically explain away things they don't understand (possibly to save face) while the young examine them. With increasing age these kinds of automatisms might simply override or detoriate learning strategies that are required to learn quickly.


Not very insightful. If you're used to video games, you have an inherent advantage over any "new" problem that is posed in terms of a video game.

Even simple things like automatically switching your mind off because you find video games less interesting than a blackboard (which is the case for me) have to be taken into account.

This is really the same as intelligence tests that make assumptions over the cultural environment.


I've always thought of this as precompiled vs interpreted; i.e. the more experience someone has the more hard-wired their response to that scenario; which makes people with more experience faster at reacting to familiar situations, but less adaptable should a different response be required or to some previously unseen variation in that initial situation.
