Jean is a model of early cognitive development based loosely on Piaget’s theory of sensori-motor and pre-operational thought [1]. Like an infant, Jean repeatedly executes schemas, gradually extending its schemas to accommodate new experiences. Jean’s environment is a simulated “playpen” in which Jean and other objects move about and interact. Jean’s cognitive development depends on several integrated functions: a simple perceptual system, an action-selection system, a motivational system, a long-term memory, and learning methods. This paper provides an overview of Jean’s architecture and schemas, and it focuses on how Jean learns schemas and transfers them to new situations.
