Research Abstract

This study examines the mechanisms in the human mind that are involved in the shift from unrelated rote knowledge acquired by learning examples of objects or events into a flexible conceptual system by which we can conceive something not experienced as a recombination of the examples. Although many researchers have suggested that compositional symbolic concepts should be sensorimotor grounded, how this may be accomplished remains unclear. This study bridges the gap by reconsidering “structural alignment" hypothesis from a constructivist view. Proposed sub-symbolic learning model emits “structural alignment" of behavioral concepts based on given sensorimotor similarity of robot's behavioral patterns and can recognize and re-generate previously unseen behavioral patterns in terms of the recombination of known patterns.
