One domain of development that impacts the other two is cognitive development, which refers to the growth and changes in a person's intellectual abilities, including thinking, reasoning, and problem-solving skills. Cognitive development affects both physical and socio-emotional development.

For example, let's consider a toddler learning to walk. This represents physical development. As the toddler starts to walk, they need to use their cognitive abilities to plan and coordinate their movements. They have to think about shifting their weight, controlling their balance, and coordinating their muscles to take each step. So, cognitive development directly influences physical development in this case.

Additionally, this newfound ability to walk opens up new opportunities for the toddler to explore their environment and engage in social interactions. They can now move around and interact with others, which impacts their socio-emotional development. They might start to develop new social skills, such as playing with other children or joining group activities, which involves cognitive processes like understanding social cues, sharing, and taking turns.

In summary, cognitive development in this example has a direct impact on physical development by enabling the toddler to walk and a secondary impact on socio-emotional development by facilitating new social interactions and opportunities for learning and growth.
