Skilled Performance. Part II.

Abstract : The report undertakes to analyze the nature of skilled performance and to develop a theoretical basis for the understanding of man's performance capacities. The first section of the report develops a framework for the experimental study of skilled performance. It deals with the taxonomy of tasks, with the measurement of human performance, and with several mathematical and physical models that are useful in guiding research and in theoretical organization of the empirical data from investigations of skill processes. The second section reviews systematically the empirical data from researches on skilled performance, with emphasis on studies that have dealt with the effects of task variables. (Author)
