Key Concepts Preview
The Three Systems (Popular Model)
The "triune brain" (reptilian / limbic / neocortex) is a popular teaching model, but modern neuroscience rejects it as an evolutionary story. Brains don't stack older-on-newer that way, and these regions don't cleanly map to single functions. Use it as a metaphor, not a map.
| Layer (metaphor) | Popularly associated with | Keep in mind |
|---|---|---|
| Brainstem | Basic survival, arousal | Not "reptilian"; shared architecture across vertebrates |
| Limbic regions | Emotion and memory | Limbic "system" is loosely defined, not a neat module |
| Cortex | Planning, abstract thought | Works in tight loops with subcortical regions, not on top |
Nature vs. Nurture
Human behavior emerges from:
- Genetics (twin studies typically estimate heritability of personality traits around 30-50%, but heritability is a population statistic, not a fixed slice of any individual's character)
- Environment (family, culture, experiences)
- Gene-environment interaction (genes influence how we respond to environment)
The Unconscious
Most mental processing happens outside awareness:
- Automatic behaviors
- Implicit biases
- Emotional reactions
- Pattern recognition
