1. The Dictionary as Mirror of the Mind Stevan Harnad with collaborators: Alexandre Blondin-Massé Guillaume Chicoisne Yassine Gargouri Odile Marcotte Olivier Picard

2. What is cognition? The activity of whatever mechanism generates performance capacity: human (and human-like, animal, machine) know-how and "know-that"

3. According to Computationalism: Cognition is just a form computation i.e., formal symbol manipulation

4. The Symbol Grounding Problem The Chinese/Chinese dictionary-go-round

6. Hence Cognition is not just computation Meaning is not just definition

7. Dynamical systems and sensorimotor grounding

8. Concepts: Formal vs. Mental (Neural)

9. What are concepts? Categories and names of categories

10. What are categories? To categorize is to do the right thing with the right kind of thing.

11. A cognizer is an autonomous sensorimotor system that categorizes

12. Miscategorization has consequences

13. Categories are classes of objects, events, properties, actions, or states with invariant features some (all? most? many? enough?) of them sensorimotor features discernible by a categorizer allowing the categorizer to categorize correctly

14. Categories have extensions and intensions

15. set membership/inclusion

16. Vanishing intersections : Categories are not just sensorimotor either

17. Category Acquisition Implicit and explicit learning

18. Implicit vs Explicit Learning =+ ++ …

19. Names and propositions

20. =+ ZEBRA = HORSE + STRIPES

21. apple red apple apple (is) red

22. sets membership/inclusion

23. Doing, naming, describing and defining Using a word and defining a word

24. Definition and introspection Cognitive science is making the implicit explicit

25. Our brains contain an implicit dictionary that enables us to name things and to use words and (sometimes) to define the words we use

26. Category Learning and Categorical Perception

27. Inborn and learned sensorimotor invariants
