Automatic Control

Paradoxically, skilled performance is highly automatic but precisely controlled.  For example, skilled typists produce complex sequences of action quickly and accurately but have little conscious awareness of where the letters are on the keyboard and which fingers they use to strike each letter.  I will present a theory of automatic control of skilled typing that resolves this paradox.  The theory simulates skilled typing, producing sequences of keystrokes with no top down control beyond the intention to type a word.  The theory predicts errors typists make quantitatively and qualitatively, matching several benchmark predictions and (nearly) passing a Turing test that asked people to distinguish computer errors from human errors.
