Expertise: the ability to efficiently process information by automatically filtering out irrelevant data and focusing on signal, achieved through structured pattern exposure that changes perceptual processing itself rather than simply accumulating more information
Why This Is a Definition
This definition captures the core concept of expertise as presented in the lesson, distinguishing it from mere information accumulation and emphasizing the perceptual filtering mechanism. It establishes expertise as a category (efficient signal processing) with differentia (automatic filtering of irrelevant data, focus on signal, achieved through structured pattern exposure that changes perceptual processing). It precisely distinguishes expertise from related concepts like 'verbose novices' and explains why it's not about processing more information but processing less through better filtration.
