'Second-Order Learning' as a Source of Structure Stabilization in Both Individual Learning and Cultural Evolution

Colin Dawson

The last decade-plus of research on infant language development has revealed a number of powerful statistical learning mechanisms that may help to solve some key problems for learners of language. However, in order for a cognitively realistic learner to arrive at appropriate generalizations in the face of an infinite number of regularities in the input, constraints on learning must be present. Several broad classes of constraint have been proposed, ranging from those instantiated in hardware (e.g. the sensitivity of perceptual systems to a restricted set of inputs) to rich built-in knowledge about the properties of the environment (e.g. Universal Grammar). One potential source of constraints might be a cyclical bootstrapping process whereby learners preferentially consider generalizations that depend on features and relationships that have proved reliable in their past experience. I present data from rule-learning studies with infants that suggests that past reliability of certain features predicts, for more experienced learners, whether a generalization over those features will be easy to learn. If this is true for human-produced environments such as language and music, it would constitute a positive feedback loop over structural regularity that would have implications not only for individual learning, but for the evolution of the domain over generations.
