Requirements: high-level symbolic capabilities (Dyer, 1994)
- creation and propagation of dynamic bindings;
- manipulation of recursive, constituent structures;
- acquisition and access of lexical, semantic, and episodic memories;
- control of multiple learning/processing modules and routing of information among such modules;
- grounding of basic-level language constructs (e.g., objects and actions) in perceptual/motor experiences;
- representation of abstract concepts.
