How do infants' brains respond when adults interact with them positively?

When adults interact with infants positively, the infants' brains become more active. Positive interactions, such as smiling, talking, and using engaging body language, stimulate neural pathways and promote brain development. This increased brain activity is essential for learning and development as it helps infants process emotions, build social skills, and develop cognitive abilities. Engaging positively not only fosters connections between neurons but also helps create a nurturing environment for infants which is crucial for their overall growth. This heightened activity reflects the infant's responsiveness to social stimuli and their ability to engage in the world around them, laying the foundation for healthy development.
