Sharing Tales That Teach: Protocol for a cohort-embedded randomised trial of caregiver-delivered emotion-focused shared reading in young children

The Emotional Gym for Little Minds

Imagine your brain as a bustling city. In this city, there are two very important departments: the Executive Function office, which handles planning, focus, and stopping yourself from doing something impulsive (like grabbing a cookie before dinner), and the Emotion Regulation department, which manages the city's weather—keeping the storms of anger or sadness from flooding the streets. When you are young, these departments are still under construction. They rely heavily on a "construction crew" made up of your parents or caregivers. This crew doesn't just build the buildings; they help the city manage its weather by talking about feelings, naming them, and showing how to calm down when things get stormy. This process is called co-regulation.

Scientists have long known that reading picture books together is a fantastic way to build the city's language skills. But a new question is bubbling up: Can we use storytime not just to teach words, but to specifically train the "weather department"? If a parent and child read a book and talk about why a character is sad or how they can feel better, does that make the child better at handling their own real-life emotions? This is the big question researchers are asking. They want to know if turning storytime into a "feelings workshop" is a special superpower, or if just reading together is enough to do the job.

The Story of "Sharing Tales That Teach"

This paper is a detailed blueprint for a big experiment called "Sharing Tales That Teach." It's not a report on what has already happened, but a plan for what will happen. The researchers, based at the University of Greenwich, are setting up a massive study to see if a specific kind of reading can help children aged 4 to 5 years old get better at managing their emotions.

Here is how the experiment is set up: The team plans to find about 400 parent-child pairs in schools in south London. They will split these families into two groups. One group of about 200 families will be part of a "trial" where they are randomly assigned to one of two reading programs. The other 200 families will just be part of a "watching" group; they will be measured but won't get a special reading program, allowing scientists to see how kids naturally grow over time.

The two reading programs for the trial group are designed to be twins, with one tiny but crucial difference. Both groups will read the same picture books for eight weeks, doing three sessions a week. Both groups will get video training and weekly check-ins.

• Group A (The Active Control): These parents will learn "standard" reading tricks. They will be taught to ask questions like, "What is the dog doing?" or "What happens next?" This is called dialogic reading, and it's great for language and story understanding.
• Group B (The Emotion-Focused Group): These parents will learn the exact same tricks, plus a special "feelings" toolkit. They will be coached to stop and ask, "Why is the bear feeling scared?" or "What could the bear do to feel calm?" They will practice talking about causes, consequences, and ways to cope with big feelings.

The researchers want to see if Group B ends up with better "weather control" than Group A. If Group B is better, it proves that the extra focus on feelings adds something special, rather than just the act of reading together doing all the work.

What They Are Looking For

The scientists aren't just asking the parents how the kids are doing; they are using a mix of tools to get the full picture. They will measure three main things one year after the study starts:

1. Parent Reports: Using a checklist called the Emotion Regulation Checklist, parents will rate how well their child handles emotions.
2. Child Reports: The children themselves will use a special tool called SAY-FEEL to tell the researchers how they manage their feelings.
3. Brain Waves: For the families in the trial group, the children will visit a lab to have their brains scanned with EEG (electroencephalography). Specifically, they are looking at frontal alpha asymmetry, a pattern of brain activity that scientists think is linked to how well we regulate emotions.

They will also check if the kids get better at executive function (like focusing and remembering things) and if the parents feel more confident and less stressed.

The Rules of the Game

The researchers are being very careful to make sure the results are real. They are using a "randomized" system, which means the families are assigned to groups by a computer, like flipping a coin, so that the groups are fair and equal at the start. They will compare the results of the two groups after adjusting for how the children started out, so they can see who actually improved more.

Because this is a plan for a future study, there are no "winners" or "losers" yet. The paper doesn't say that emotion-focused reading will work; it says this is the protocol (the rulebook) for finding out if it does. The researchers admit that they can't hide the difference from the parents (since the parents are the ones teaching the techniques), which might make the parents' answers a little biased. However, by using the child's own report and the brain scans, they hope to get a clear, honest answer.

Why This Matters

If this study finds that the "feelings toolkit" works, it could change how parents and teachers use storytime. Instead of just reading for fun or to learn words, they might be able to turn a simple picture book into a powerful training session for emotional health. If it doesn't work, that's important too—it would suggest that just reading together is enough, and we don't need to add extra pressure to talk about feelings.

For now, the researchers are just getting ready. They have the plan, the books, and the questions. They are waiting to see if turning storytime into a "feelings gym" can help the next generation of city-builders keep their emotional weather calm and clear.
