According to this article, older adults who played video games improved their cognitive functioning, particularly their processing speed, and ability to switch rapidly between tasks. This actually isn’t all that surprising, insofar as video games would load heavily on fluid intelligence, otherwise known as performance IQ. As opposed to Verbal IQ (or crystallized intelligence), performance IQ measures the ability of an individual to learn and adapt to novel tasks, including visual-spatial stimuli. Verbal IQ, by contrast, has more to due with acquired knowledge and language. Video games clearly fall into the performance IQ domain, with the heavy emphasis on solving different puzzles along the way, a reliance on performing quickly, and information being provided primarily through visual cues. This sort of task would be particularly novel to older adults, who would have no latent skills in hibernation from childhood, given that this stuff didn’t exist 30 years ago. All kidding aside, this is a good recommendation. Older adults are prone to developing a rigidly of thought as they age, and being exposed to activities like video games is an excellent way for older adults to flex certain mental muscles they may not have used in a long time. Conversely, younger kids would do well to make efforts to engage in activities like reading full-length books, in order to develop attention spans that don’t require the incessant reinforcement provided by video games.
