The report reviews a number of schemes designed to describe the human behaviors occurring during task performance. The purpose of the review was to assess whether such schemes would be useful in classifying tasks per se. Included in the review were schemes which employed such conceptual units as functions, abilities, and overt behaviors. In general, the available schemes are hampered by one or more of several factors a imprecise terms b little measurement capability or c a lack of development of the scheme to a point where it may be readily applied to real-world tasks. The logic of describing tasks in behavioral terms is examined with a final conclusion being reached that tasks per se are more appropriately described in terms of non-behavioral task characteristics.
