Comprehension-based skill acquisition

We present a comprehension-based computational model of UNIX user skill acq uisition and performance in a training context (UNICOM). The work extends a comprehension-based theory of planning to account for skill acquisition an d learning. Individual models of 22 UNIX users were constructed and used to simulate user performance on successive command production problems in a t raining context. Comparisons of model and the human empirical data result i n a high degree of agreement, validating the ability of UNICOM to predict u ser response to training.
