Dual-Coding Theory

Why pairing words with pictures helps a story sink in — and why that's different from watching a screen.

The Science

There is a long-standing idea in psychology called Dual-Coding Theory, developed by Allan Paivio. It proposes that we have two channels for taking in information — one for words and one for images — and that when both work together, we understand and remember more than when either works alone.

This is why an illustrated, narrated story is such good food for a developing mind. The words and the pictures reinforce each other, and the child has to do the work of joining them up. Watching television is more passive by comparison: the images and sound arrive already finished, asking less of the child. BAMJOY pairs narration with illustration on purpose, so both channels are switched on and working together.

For Parents: Try This Tonight

When you're choosing between story time and screen time, it isn't just about limiting screens — it's about what each one asks of your child's brain. An illustrated, narrated story invites your child to actively connect words and images. A video does that connecting for them.

Watching a video

In one ear, out the other…♪♪

Sound and pictures arrive already joined up, so there is less for your child’s brain to do.

Sharing an illustrated story

Once upon a time…foxice

Words come in through the ears, pictures through the eyes — and your child’s brain does the joining up.

Illustrations. Screens aren’t bad — the difference is how much each one asks your child to do.
