Abstract

Human cognitive abilities are remarkable, and even more remarkable is the rapidity with which children develop cognitive insight. How does this insight arise? A pervasive view in cognitive development is that these rapid gains can only be explained by assuming that infants begin with substantial amounts of innate knowledge. In this talk I propose an alternative approach, centered on mechanisms of human learning. I suggest two powerful forces that contribute to human learning and reasoning ability: (1) analogical processing; and (2) the acquisition of relational language. I will present evidence that the structure-mapping processes that occur during analogy and similarity are a core mechanism by which abstract knowledge arises from experience. Our studies of learning in adults and children show that analogical comparison processes foster learning in several ways: by aligning common relational structure, by suggesting inferences between situations, by focusing attention on relevant differences, and by inviting relational abstractions.

A further contributor to human learning and reasoning is the acquisition of relational language. Relational language provides labels that preserve and systematize the relations discovered through comparison processes. It also acts to invite analogical comparisons that reveal common structure. In sum, I suggest that mutual bootstrapping between structure-mapping processes and relational language is a major contributor to human cognition.
