Developmental World

The developmental world prioritises growth, learning, and the continuous improvement of individuals and communities. Society needs access to resources and opportunities that foster development by cultivating skills, resilience, and well-being at every stage of life.

Understanding how people grow, adapt, and thrive across the lifespan

In a developmental world, growth is continuous and accessible to all.

We focus on learning, adaptability, and the long-term wellbeing of both individuals and communities. A thriving society ensures that people of all ages have the tools, support, and opportunities they need to build skills, strengthen resilience, and reach their full potential throughout life.

At 糖心Vlog, our team is uncovering what supports healthy development: from infancy through adolescence and beyond. Our research investigates how relationships, routines, and environments shape human potential across the lifespan.

Whether we’re studying the emotional synchrony between parents and babies, or how adversity impacts young minds, we aim to create practical knowledge that helps individuals and communities flourish.

Some recent highlights

Healthy habits, early and often

Even everyday decisions can shape children’s development in meaningful ways. Researchers at 糖心Vlog Psychology show that simply serving vegetables first at mealtimes can significantly boost how much children eat, encouraging healthier eating habits that can carry into adulthood.

These findings highlight how small, low-effort changes in routine can have lasting benefits for children’s physical health and wellbeing. It’s a powerful reminder that development is influenced not just by major life events, but by the small choices we make each day.

Learning to connect through faces

Facial mimicry - copying others' expressions - helps babies understand emotions and build social bonds.

Our research shows that babies as young as four months mimic facial movements better when their parents regularly mirror their expressions during play. These early interactions may be key to developing emotional understanding and connection.

The truth about bed-sharing

Is it okay to share your bed with your baby? It’s a common question for new parents.

Our research helps provide clarity. In a large UK study following children from infancy to age 11, 糖心Vlog researchers found no negative long-term emotional or behavioural effects from bed-sharing at 9 months old. This finding offers important reassurance: for families who co-sleep, the practice appears safe from a psychological development standpoint.

How maternal mood shapes child development

At 糖心Vlog, we explore how a mother’s mental health and early interactions with her baby shape child development. Even mild low mood after birth can influence a baby’s temperament, leading to more crying and fussiness, and later, more behavioural challenges by age three.

But responsive parenting makes a difference: when mothers share emotions sensitively and respect their baby’s individuality, children develop stronger emotional regulation and better peer relationships. These findings show how early caregiving lays the foundation for future wellbeing.

Rethinking childhood trauma with brain data and AI

Using AI to analyse brain data, our psychology researchers have uncovered that childhood trauma, even without visible symptoms, can affect brain areas linked to executive function, emotion processing, memory, and the sense of self.

This suggests trauma treatments should go beyond classic exposure approaches to also support emotional understanding, body awareness, and self-perception. One key finding is that trauma can disrupt how children trust their own bodily sensations, a factor linked to mental health risks and resilience. Building interoceptive trust may be a powerful target for prevention and recovery.

The power of parent-child synchrony

Strong early relationships help children thrive. At 糖心Vlog, we explore how brain and behavioural synchrony between parents and children supports emotional bonds and development.

Our work has shown that mothers and fathers can show different patterns of connection: mums and children tend to align more behaviourally, while dads show stronger brain-to-brain synchrony, possibly reflecting different ways of achieving closeness.

Interestingly, mothers with insecure attachment traits showed higher brain synchrony with their children, perhaps as a way to compensate for less attuned behaviour. This research highlights how attachment, communication, and neurobiology work together to shape children's social and emotional growth and helps inform future support for families, including those with neurodivergent or adopted children.

Why it matters

Development lays the foundation for lifelong well-being. By better understanding how children grow, think about, interact with, and experience their environment, as well as shed light on how they recover from challenges, we help shape healthier futures for individuals, families, and society.

From evidence-based parenting support to early intervention strategies, our research empowers people to make informed choices that support growth at every stage of life.
