Many of our daily actions happen without us really thinking about them. Brushing our teeth, checking our phone, or taking the same route to work — these are habits. In this article, I explain the simple psychological model that shows how habits form and give you a clear, everyday example so you can understand and even change your own habits.
The Cue-Routine-Reward Model
"A “habit loop” is a way of describing several related elements that produce habits. These elements have been called the cue (or trigger), the routine (or behavior), and the reward" (Psychology Today, 2025).
This model helps us see habits as a three-part loop that our brain uses to save energy. The cue is the signal that starts everything. It can be a time of day, a place, an emotion, or even a smell. Once the cue appears, our brain automatically moves into the routine — the actual behavior we perform. After the routine comes the reward, which is the positive feeling or benefit our brain receives. This reward is what makes the brain want to repeat the loop again and again.
"First, a cue triggers your brain to initiate a routine, a sequence of actions that ends with a reward – something your brain likes" (Tougher Minds, 2024).
The habit loop—cue, routine, reward—is crucial in establishing lasting habits. Over time, the loop becomes so automatic that we do not even realize we are following it. This is why good habits feel easy and bad habits feel hard to break.
A Practical Example
Let’s look at a common habit: checking your phone right after waking up.
- Cue: You open your eyes and see your phone on the nightstand (the trigger).
- Routine: You pick it up and start scrolling through social media or messages.
- Reward: You feel a quick burst of excitement from new notifications, likes, or funny videos.
Your brain learns this loop and starts the routine automatically whenever the cue appears. Understanding this example shows how the same model works for both helpful habits (like exercising after your morning coffee) and unhelpful ones (like snacking when bored).
Final Thoughts
The cue-routine-reward model gives us a clear map of how habits work in our brain. Once you can see the three parts in your own life, you gain the power to change them. You can keep the same cue and reward but replace the routine with something better.
As someone with a B.S. in Psychology, I recommend picking one habit today and writing down its cue, routine, and reward. Small awareness like this is the first step toward building better habits that last.
