Final answer:
Preschool-age children show significant cognitive and social development, which are important predictors of future success.
Step-by-step explanation:
Preschool-age children (i.e., 3-5 years old) make significant developmental progress in various areas. They show cognitive growth by being able to count, name colors, make decisions, and predict what will happen next in a story. Their blossoming curiosity is evident as they frequently ask "Why?" They also engage in pretend play, inventing elaborate characters and scenarios. These skills are known predictors of future success in school and beyond.
Additionally, during preschool, children start developing vital social and behavioral skills. They learn social norms such as keeping hands to themselves, standing in line, and playing together. These early socialization experiences help them build relationships, cooperate with others, and develop essential socio-emotional skills.
