Keystroke Timing in Transcription Typing

Over the past few years, in collaboration with Jonathan Grudin, David Rumelhart, Donald Norman, and Serge Larochelle, I have been studying transcription typing in the laboratory. Typically, typists would be asked to transcribe normal English prose from typewritten copy. This corpus of naturalistic data, now totaling over half a million keystrokes, has been a rich vein of information on the development and performance of a highly practiced skilled action.
