Abstract : How to describe the mental processes and states carried out by a human subject when he performs an activity? I.e. what is a mental process or state? How to infer them from the subject’s behavior and statements? How to describe them? Our goal is to provide answers to these questions, in the context of car driving. To this end, we have collected "traces of activity" during an experiment made with an instrumented vehicle. They are sequences of events that describe the interaction of the driver with his environment. They contain data from sensors or from assessments made by the ergonomist or by the driver. We have developed a progressive process for modeling these traces. It is based on a knowledge engineering tool, which we have specifically designed and implemented. This process allows us to produce models of the activity at different levels of abstraction. From these models, we show how an ergonomist can explain the activity, in reference to his own theoretical explicative framework. The framework that we have chosen comes from cognitive psychology. It proposes to describe the mental processes and states of the subject as "cognitive schemas" carried out at different "levels of control". Our approach allows us to search and find the implementation of cognitive schemas in the activity and to propose models of these schemas. From an epistemological viewpoint, this approach is based on a "constructivist" positioning, i.e. evolutionist, pragmatic and driven by the cesses and states of the subject as "cognitive schemas" carried out at different "levels of control". Our results consist of the methodology that we have developed, the software tool that we have built, the models of the activity that we have produced, and the cognitive schemas that we have modeled.
