Psychology: Mind, Brain, and Chemistry, a free psychology course on Tomo

Psychology: Mind, Brain, and Chemistry

Discover how your mind creates experience, how your brain is physically organized, and how chemical signals drive your thoughts, moods, and actions. Move from classic behavioral theories into the functional anatomy of the lobes and the molecular machinery of neurotransmitters.

Like Duolingo, but for Psychology: Mind, Brain, and Chemistry. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.

25 levels across 3 sections, about 50 minutes end to end, roughly 10 days at five minutes a day. It moves through How the Mind Explains Behavior, The Brain's Physical Architecture, and The Chemical Engine. It starts from scratch.

What you'll learn

Key ideas in Psychology: Mind, Brain, and Chemistry

  • Involuntary bodily reflexes like nausea or fear naturally respond to direct biological events (like toxins or pain)
  • When a neutral cue (like a sound or smell) happens right alongside that biological event, the brain links them automatically
  • Once paired, the neutral cue alone can trigger the involuntary physical reflex without conscious thought
  • Behaviors followed immediately by a satisfying payoff are reinforced and more likely to happen again
  • Immediate friction, discomfort, or total lack of response weakens a voluntary behavior
  • Delays between an action and its outcome sharply weaken the brain's ability to link the two
  • Unpredictable rewards create heightened anticipation compared to guaranteed outcomes
  • Behaviors rewarded on an intermittent or variable schedule are much harder to stop, persisting long after rewards dry up
  • Fixed, predictable rewards lead to boredom or quick cessation once the reward is slightly delayed
  • Habits begin when a specific environmental trigger (time, location, emotional state) is perceived
  • The brain initiates the automated behavior routine before deliberate conscious reflection intervenes
  • The routine delivers a quick relief or satisfying payoff that locks the loop in memory for next time
  • Extinction happens when the brain experiences the cue over and over again without the associated reward or consequence
  • Simply avoiding the cue does not extinguish the conditioned response; it just keeps the dormant association intact
  • Extinction teaches the brain a new safety signal rather than completely erasing the old memory
  • The brain uses schemas as mental templates to quickly fill in missing details during ambiguous events
