Interaction Modeling
User actions and cognitive modeling...
"Interaction modeling is a good way to identify and locate usability issues with the use of a tool. Several methods exist (see Olson & Olson 1990 for a review of techniques). Modeling techniques are prescriptive in that they aim to capture what users will likely do, and not descriptive of what users actually did.
Most methods—descriptive or prescriptive—fail to incorporate the relationship between user actions and cognitive processes. Models of cognitive processing, for example, might attempt to explain how or why a particular task is mentally difficult, yet the difficulty does not directly relate to observable user actions. Conversely, descriptive techniques such as path metrics, click stream analysis, and bread crumb tracking take little or no account of cognitive processes that lead to those user actions.
The relationship between actions and cognitive processes is important because it explains user behavior and translates to supportive arguments for good design solutions. Both prescriptive and descriptive techniques are necessary for characterizing the cognitive processing and user action (cog-action) relationship." continued ... (Via boxes and arrows)
