# Why do power laws describe learning and skill acquisition so well?

In humans, why do powers laws describe skill acquisition? In particular, $$RT = aP^{-b}+c$$ where $RT$ is reaction time and $P$ is amount of practice.

• Does the power law generalise to learning in other mammals?
• Does the power law apply to learning whilst under the influence of drugs or alcohol?
• Does the power laws apply to creative ideas or just to tangible skills?

Each of these questions are probably enough for a stand alone question. Is there a particular question that you want to focus on? –  Jeromy Anglim Aug 6 at 4:10
