Variations on a Theme
Despite their differences, models involving levels of brain organization, emotion, signs, and reference suggest consistent underlying themes for each level of cognition. As levels of an emergent system, each theme should relate to a type of interaction. Based on the identified themes, we can organize these interactions into sensory, intuitive, and abstract.
Sensory interactions: instinctive, body, iconic
- Iconic reference: unconscious substitutions based on physical resemblance between signifier and signified
- Reactive / Visceral: responses based on instinct, physical sensation
- Reptilian Complex: instinctive behavior, “lizard brain”
Intuitive interactions: habitual, memory, indexical
- Indexical reference: remembered mappings based on co-occurrence of signifier and signified
- Routine / Behavioral: responses based on habits, memory, learned behavior
- Limbic System: pro-social behavior, “mammalian brain”
Abstract interactions: reflective, thought / language, symbolic
- Symbolic reference: learned networks of substitution and mapping based on assignment of signifier to signified
- Reflective: responses based on thought, language, reasoning
- Neocortex: reflective behavior, “human brain”
