Overview
Project Nemo examines the cognitive processes and representational structures used by submarine Commanders while attempting to locate an enemy submarine hiding in deep water. In phase 1 we collected protocol data from commanders with 20 years of submarine experience. These data suggest a shallow goal structure with a basic level of subgoals that are used by all Commanders throughout the task. Relatively few operators are required for each subgoal. The results are congruent with a schema theory interpretation in which the process of schema instantiation provides the control of cognition.
In phase 2 we collected performance and protocol data from junior, mid-career, and senior submarine officers. The data support the conclusions from phase 1 that most AO actions can be characterized as a sequence of small, steps in a shallow goal hierarchy (rather than as following a detailed master plan). The nature of these successive choices vary as a function of the officerÍs expertise. The results are congruent with an interpretation in which the process of schema instantiation provides the control of cognition.
