How the Brain Shapes Behavior

An interactive quiz explaining the triune brain model. It turns neuroscience into a quick pattern-matching game.

Goal

I set out to build a simple quiz about the triune brain model.

Instead of a lecture, I wanted people to learn by spotting patterns in their own behavior.

Players apply the model to everyday situations and build intuition about how the different systems work.

This quiz is part of a larger project explaining how depression works and how different brain systems interact in emotional regulation.

The experience begins with a very short introduction and quickly moves into questions.

The quiz has two stages:

Stage 2. Recognizing which system is driving behavior in real-life situations.

Learn first, then apply.

Each question describes a short everyday scenario: reacting emotionally, acting automatically, focusing intensely, or avoiding something stressful.

The player chooses which brain system is most responsible for the reaction. After answering, they receive a short explanation.

Abstract neuroscience becomes a pattern-matching game.

Questions are drawn randomly from a larger pool.

This means that each playthrough is slightly different and players can repeat the quiz without getting exactly the same experience.

At the end of the quiz the player receives a summary showing how accurately they identified the different brain systems.

The result also serves as a reflection point. It helps players see which systems they understand well and which ones they still confuse.

The final result can be shared on social media.

People share results and compare with friends.

Play it once quickly, trusting your instincts. Then replay and see how your answers change once you know the systems better.
