Information, Perception, and Cognition

• There is a chain of processes between physical events and their perception by humans:
  1. generation of energy
  2. transmission of energy from event to observer
  3. reception and processing by ear/eye
  4. transmission of signals to the brain
  5. more processing: interpretation, formation of a representation

• Cognition: set of mental abilities and processes related to knowledge: attention, memory, judgment, evaluation, learning, understanding, remembering;
