This is just an abstract, so maybe I am missing something, but it sounds like a subtle moral judgment is being inserted here that faster is better: younger people react faster often because of impulsivity. Why should we believe that a faster response time is a good thing, aside from swerving to avoid an accident and the like? Is that what was under measure here?
