And they remarked repeatedly in their paper that they were quite surprised that they found no relation between self-reported health and cognitive status; between personality and cognitive status; nor between the active lifestyle, self-report and cognition and by active lifestyle they were referring to people’s hobbies and physical fitness activities. They did see, however, a relationship between participation in what they called novel tasks and working memory. By novel tasks they were asking people to talk about things they learned such as a new language, did they learn bridge, if they were acquiring sort of complex mental skills later in life. Now, they honestly called an alternative interpretation which I think doesn’t come up in many other studies that apply to a lot of them that I read and that is that high-ability adults end up leading intellectually active lives when they’re young and as they age. Whether you can call this a predictor, it isn’t facilitating good cognition, it’s what they’ve always had and so they are likely to maintain a higher level of cognition as they age relative to other people.
