Mammalian brain · Affect & Drives

Arousal-Valence Model

Emotions map onto two axes — how activated you are and how pleasant it feels; high arousal of either sign speeds decisions and sharing, low arousal slows them.

An everyday example

Excited and anxious buyers both decide fast; content buyers browse; sad ones stop.

What it can cost you

Being moved by arousal rather than by direction — an exciting pitch and a frightening one both shorten your thinking.

Warning signs

  • I am buzzing.
  • The decision feels urgent and I cannot say why.

One thing to do

Locate yourself on the map before deciding: if arousal is high, wait for it to drop regardless of whether it feels good or bad.
