Technical discussion of Piagetian cognitive stages applied to uncertain inference systems

194 11 Stages of Cognitive Development Piaget Meets Uncertain Inference Full self modification Capable of self-modification of internal structures Able to carry out arbitary complex inferences (constrained Formal only by computational resources) via including inference control as an explicit subject of abstract learning Able to carry out more complex chains of reasoning via using Concrete inference control schemata that adapt behavior based on experience (reasoning about a given case in a manner similar to prior cases) Able to recognise patterns in and make inferences about the Infantile world, but only using simplistic hard-wired (not experientially learned) inference control schema.
