The Architecture of the Mind

Like Duolingo, but for The Architecture of the Mind. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.

For the part of you with thirty open tabs that never became anything.

A short one: 12 levels across 2 sections, about 24 minutes end to end, roughly 5 days at five minutes a day. It moves through How the Brain Builds Reality and The Social and Behavioral Engine. It assumes you already know the basics.

Key ideas in The Architecture of the Mind

  • Perception is a 'controlled hallucination' constrained by sensory input
  • Signal Detection Theory separates sensory ability from decision criteria
  • The brain uses top-down processing to fill in gaps using prior expectations
  • Response bias shifts based on the perceived costs of errors
  • Ambiguous stimuli are interpreted based on the most likely environmental model
  • A 'liberal' criterion increases hits but also increases false alarms
  • Perception as an active construction
  • Signal Detection Theory Application
  • Priors represent the brain's existing internal model of the world
  • Adaptation filters out static 'noise' to preserve neural bandwidth
  • Prediction error is the 'surprise' signal when data defies expectations
  • Perception as an active construction rather than a passive recording
  • The brain prioritizes 'change detection' over constant state monitoring
  • The posterior belief becomes the new prior for the next interaction
  • Neural firing rates decrease for unchanging stimuli to increase sensitivity to new inputs
  • Application of Signal Detection Theory based on situational stakes
