What’s the Science Behind Tantrums? Decoding the 4 Functions of Behaviour

To effectively stop a tantrum, you have to understand exactly why it is happening. Behaviour is never random; it is always communication. If you apply the wrong strategy to a tantrum, you will likely escalate the behaviour.

In behavioural science, almost all behaviour serves one of four distinct functions. Once you decode which function is driving your child's meltdown, the solution becomes clear.

"All behaviour is communication. When a child is screaming, they are using the only tools they have to tell you what they need."

The Four Functions of Behaviour (SEAT)

• S - Sensory: The child is overwhelmed by lights, noise, or textures, or they are desperately seeking physical input. Solution: Remove them from the environment, dim the lights, or offer deep pressure (like a tight hug or weighted blanket).

• E - Escape: The child is trying to avoid a task they find too difficult, boring, or overwhelming (e.g., homework or brushing teeth). Solution: Break the task down into tiny, manageable steps, or offer choices to give them back some control.

• A - Attention: The child feels disconnected and will take negative attention (you shouting) over no attention at all. Solution: Ignore the negative behaviour if it is safe to do so, but heavily praise and connect with them the moment they show positive behaviour.

• T - Tangible: The classic tantrum—they want a toy or a snack, and you said no. Solution: Hold the boundary firmly. Do not give in to the item, or they will learn that screaming is an effective negotiation tool.

By pausing to ask yourself, "What is my child actually trying to achieve right now?" you shift from emotional reactivity to clinical, effective problem-solving.
