cog•ni•tion [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”

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.

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