Explore the non-linear journey of brain development with Emerging Scholar CoCreator, Lucinda Sisk


Delve deep into the fascinating topic of non-linear brain development in children and explore the intricate workings of the developing brain and its profound impact on our children's growth and abilities.

Brain Development is Non-linear 

Brain development is non-linear, meaning that different brain circuits and the functions they support mature at different rates. These differences in the developmental timing of circuit maturation can shape children's abilities and behavior as they get older." 

Lucinda Sisk

  • Understanding non-linear brain development involves recognizing that different brain circuits and functions mature at different rates. This means that certain skills or abilities may develop faster or slower than others, creating variations among children. As CoCreators this is vital to understand so that we are always considering individual differences and unique developmental trajectories.

  • The uneven development of brain circuits directly influences various aspects of a child's abilities and skills. Some areas may be more advanced or active than others during specific developmental stages. For example, language skills may develop earlier than certain cognitive abilities, and social-emotional development may have different trajectories. By understanding these variations, we can better support our children in their growth and provide tailored guidance.

  • Brain development research has yielded valuable insights into the non-linear nature of development. For instance, we know that the prefrontal cortex, which plays a major role in cognition, emotion processing, and behavior, continues to develop into young adulthood. In contrast, the amygdala, a region responsible for detecting and signifying important external events, develops relatively earlier. This juxtaposition in circuit development is thought to help explain some of the behavioral changes that frequently occur during adolescence, such as increases in risk-taking behavior and exploration beyond the home and family environment.*

Listen as Lucinda Sisk gives examples of different types of brain circuits that develop in different ways during childhood and how an understanding of this non-linear development can influence adult expectations of children.

CoCreator Activity: Adapting Your Approach

Reflect on a child's current developmental stage and consider one specific aspect of their development, such as social skills, emotional regulation, or cognitive abilities. Take some time to understand the typical milestones and characteristics associated with that aspect. Then, brainstorm ways you can adapt the way you support them to better align with the child's needs. Implement these strategies in your daily interactions and observe the outcomes. By making intentional adjustments and providing tailored support, you can foster a nurturing environment that promotes a child's emotional well-being.

Aligning Brain Development with Scaffolding Emotional Health

Scaffolding emotional health involves providing support and guidance to foster children's emotional well-being. It is through this practice that we create a nurturing environment where children can thrive emotionally.

Let's explore more about brain development and creating a strong foundation for kids’ emotional growth.

  • Understanding brain development allows CoCreators to scaffold their child's emotional well-being by providing appropriate support and creating a nurturing environment. By being aware of their child's developmental stage, CoCreators can tailor their parenting approaches to meet their child's specific needs and promote emotional growth. As Lucinda Sisk explains, "By understanding brain development, CoCreators can provide the necessary support that aligns with their child's stage of development, fostering emotional well-being."

  • CoCreators can adapt their scaffolding approaches by observing and attuning to the specific emotional needs, strengths, and challenges of children. This allows for personalized support and the promotion of optimal emotional development. As Lucinda highlights, "Adapting approaches may involve using different language, visual aids, or other creative methods to help young children understand and express their emotions effectively."

  • As CoCreators, it's important to pay attention to observable signs and cues in children that provide insights into their emotional well-being. These signs may include their responsiveness to emotions, their ability to self-regulate, their curiosity and engagement in learning, and their social interactions. By paying attention to these indicators, CoCreators can tailor their scaffolding approaches to meet the specific needs of each child, even as they change over the course of development. Such attentiveness helps create a supportive environment that nurtures childrens’ emotional growth and well-being. 

Strategies to Foster Emotional Health and Brain Plasticity:

  • Acknowledge and respond to children's emotions in a developmentally appropriate way. Validate their feelings and provide a supportive and safe environment for emotional expression. As Lucinda Sisk emphasizes, “Recognizing and being responsive to childrens’ emotions helps support their own emotional development.” 

  • Support children in developing emotional regulation skills through supportive interactions and modeling. Provide them with tools and strategies to manage and express their emotions effectively.

  • Foster a safe and nurturing environment that promotes exploration and emotional expression. Create opportunities for children to explore their emotions and encourage open communication.

CoCreator Activity: Emotional Well-being Check-in

Take a moment to reflect on the emotional well-being of the children you care for as a CoCreator. Consider their current emotional needs and any challenges they may be facing. Then, think of one specific action you can take to support their emotional well-being. Implement this action in your daily interactions with the children and observe any changes it may bring. Reflect on the experience and consider how you can continue to support their emotional growth. Remember, your efforts as a caring adult can have a profound impact on their well-being.

Nurturing Brain Plasticity in Children: Fostering Emotional Health and Well-being

CoCreators play a crucial role in shaping a child’s developing brain through their interactions, relationships, and environments. They have the power to influence the wiring of the brain and support the development of emotional skills in children."

Lucinda Sisk

CoCreators draw on an understanding of brain development to shape the developing brain by influencing the wiring of the brain through their interactions, relationships, and environments.

CoCreators' understanding of brain plasticity is crucial in recognizing our profound impact on children's emotional health. 

It allows us to appreciate that the developing brain is highly adaptable and responsive to experiences. Embracing what we know around brain plasticity, allows us to recognize that our interactions, relationships, and environments are important in shaping the emotional circuitry of the brain. As CoCreators we can create nurturing and supportive environments that foster emotional well-being in children and actively engage in practices that promote positive emotional development and create a lasting impact.

"Emotional experiences have a profound impact on shaping the developing brain. The quality of relationships with caring adults and positive, supportive interactions play a crucial role in wiring the emotional circuitry of the brain." - Lucinda Sisk

Emotional experiences wield tremendous influence over the developing brain. 

Listen to learn more about how CoCreators can create a nurturing environment that supports kids’ emotional development.

Through nurturing and responsive interactions, CoCreators can provide the necessary emotional support and guidance that allow children to navigate their emotions effectively.  CoCreators play a vital role in shaping the emotional landscape of the developing brain by:

Creating a nurturing environment that supports emotional development by providing love, empathy, and validation, teaching emotional regulation skills, and fostering a safe and supportive atmosphere that allows children to freely express themselves.

Actively teaching children how to identify and manage their emotions, offering coping strategies and mindfulness exercises. 

Encouraging open communication, actively listening to children's thoughts and feelings, and providing guidance when needed.
