1. Framework for Modeling the Cognitive Process Spatial and Temporal Considerations in a Signal-Based Approach Paul Yaworsky AFRL/IFSB 10th ICCRTS 13-16 June 2005

2. Command requires Cognition! C1 - Command C2 - Command, Control C3 - Command, Control, Communications C4 - Command, Control, Communications, Computers C5 - Command, Control, Communications, Computers, … Combat … Coalition … Consultation … Collaboration … Command & Control (C2)

3. cognition [cognoscere to know]: knowing, knowledge Other (loose) definitions of cognition include: awareness, thinking, reasoning, understanding, mental processes (esp. high order), “of the mind”… Definitions of “Cognition”

4. A “Signal-Based” Approach Signal is a generic term used for cognitive activity Signal use is modeled after pulses, oscillations in brain A Signal has frequency, phase, amplitude components A Signal exists in space and in time A Signal can be input, output, or internal activity A Signal can be data, information, knowledge, etc. A Signal can be abstract, conceptual, etc. A Signal can be formal, physical, symbolic, etc.

5. Sensors/Data Information Knowledge Wisdom Intelligence Understanding Cognitive Information Physical    DomainsTransformations Many One Pyramids Descriptions of “Cognition”

6. (Time) (Space) Information “Frame the Perspective”

7. Abstraction Generalization (Practical) (Raw) Information (Fundamental) (Theoretical) Knowledge Data Specific Abstract Concrete General Formal Conceptual Framework for Modeling Cognition

8. Describe Signals Changing in Time (e.g., temporal states) (Time) (Horizontal Dimension in Framework)

9. represents the majority of input signals has the highest frequency/shortest period is the least organized type of signals DATAKNOWLEDGEINFORMATION DATA “Data...”

10. is the most organized type of signals has the lowest frequency/longest period represents the majority of output signals DATAKNOWLEDGEINFORMATION KNOWLEDGE “Knowledge…”

11. Humans Generalize… Many Signals Timely Specific InformationKnowledgeData t = 0 t= ∞ What Happens to Mental Signals in Time? Few Signals Timeless General

12. DATAKNOWLEDGEINFORMATION The Essence of Generalization KNOWLEDGE (Time) Produces Knowledge Many signals transformed into fewer ones Time abstracted out of signals

13. Describe Signals Changing in Space (e.g., spatial forms, representations) (Space) (Vertical Dimension in Framework)

14. What Happens to Mental Signals in Space? Humans Abstract… Many Signals, Formal, Concrete Few Signals, Formless, Abstract Information Formal Concepts

15. Produces Concepts Many signals transformed into fewer ones Form abstracted out of signals INFORMATION CONCEPTS FORM The Essence of Abstraction CONCEPTS (Space)

16. Abstract, conceptual, informal, apparent, complex, combined, notional, seeming, cognitive, ideal, intangible; “mental” model of reality... Formal, concrete, certain, absolute, fundamental, simple, basic, primitive, practical, principle, factual, sensory, machine-like; “physical” model of reality... Abstraction: Two Opposing Forms

17. (Representation Across Multiple Levels) Writing Speaking Abstract, Conceptual … (“Mental”) Thinking Formal, Concrete … (“Physical”) Example of Abstraction

18. (Spatial and Temporal Considerations) Some Basic Signal Properties…

19. Signal Scaling

20. Signal Coupling

21. Signal Filtering

22. $10 $1,000,000 $0.01 Signal Significance

23. Signals proceed from “many to one”… A Main Point of the Process

24. Generalize Abstract Cognition Involves the Ability to:

25. INFORMATION CONCEPTS FORM (Space) Essence of Abstraction CONCEPTS

26. DATAKNOWLEDGEINFORMATION (Time) Essence of Generalization KNOWLEDGE

27. This conceptual framework, while relatively simple, has potentially far-reaching effects in the domain of modeling cognition. Conclusion
