Expertise as a potential insulating factor against cognitive decline in older adults has been explored in a number of domains. Some of the main foci of the literature revolve around the magnitude of the effect (criterion effects), the possibility that such exposure may transfer to other domains (near‐ and far‐transfer effects), and persistence across time. Despite concerns regarding the quality of comparison with control groups, the inevitably nonblind nature of studies, and the ultimate contributions of nature and nurture, expertise appears to preserve specific pockets of cognitive excellence in older adults.
