Expertise

1.      To have expertise, means to have expert skills at something. In chapter 21, expertise is placed with age and correlation is studied. Unfortunately, the correlation between expertise and age is not completely straightforward. In the world of careers, expertise is thought to come about as one ages and gains more experience in a specific set of skills or job type. However, it has been found that only sometimes does expertise overcome age effects. In a study where participants aged seventeen to seventy-nine were asked to identify tunes with different speeds, it was found that all experts from each age did better than the inexperienced. The only difference was that the older expert adults were slower than the younger expert adults. So, no matter what the expert’s age was, they succeeded over the inexperienced at all ages.

This was not too surprising to me since expertise specifically means to be an expert in a set of skills. I did however, think that it was possible for the older experts to do better than the young experts, due to their long experience with the skill.
