We present an analysis of an expert performing a highly interactive computer task. The analysis uses GOMs models are implemented within an unified theory of cognition called Soar. Two models are presented, one with function- level operators which perform high level functions in the domain, and one with keystroke level operators which describe hand movements. For a segment of behavior in which the expert accomplished about 30 functions in about 30 seconds, the function level model predicted the observed behavior well, while the keystroke level model predicted only about half of the observed hand movements. These results, including the discrepancy between the models, are discussed.
