Cue → [Craving →] Response → Reward

Source

Per The Power of Habit - the Habit Loop consists of three parts. Cue → Response→ reward.

Atomic Habits expands on this framework, interjecting “Craving” between cue and response. Otherwise the definitions of each part of the loop remain the same.

Definitions

  1. Cue - What triggers the behavior. Can be external or internal.
  2. Craving - the anticipation of the behavior that takes place between the cue and the behavior itself
  3. Response - The behavior itself. What we are thinking of when we think “habit”.
  4. Reward - Whatever the result of the habit is. Serves to lessen discomfort.
