The constructivist notion that features are purely functional is incompatible with the classical computational metaphor of mind. I suggest that the discontent expressed by Schyns, Goldstone & Thibaut about fixed-features theories of categorization reflects the growing impact of connectionism. Their perspective is similar to recent research on implicit learning, consciousness, and development. A hard problem remains, however: how to bridge the gap between subsymbolic and symbolic cognition.
