Which of the following describes a factor that supports cognitive development in young children?

Active engagement with varied materials significantly supports cognitive development in young children because it fosters exploration, creativity, and critical thinking. When children interact with diverse materials—such as blocks, art supplies, books, or nature—they are encouraged to investigate, manipulate, and experiment. This hands-on learning experience allows them to form connections, develop problem-solving skills, and understand concepts in a meaningful context.

Moreover, engaging with varied materials promotes sensory experiences and cognitive challenges that are essential for young children's brain development. Such interactions not only enhance their understanding of the world but also stimulate their curiosity and intrinsic motivation to learn. Through this active participation, children are likely to develop independence, resilience, and confidence in their abilities, which are all crucial aspects of cognitive growth.

In contrast, passive observation, structured learning environments, and limited peer interaction do not offer the same opportunities for discovery and critical thinking that active engagement provides. These alternative approaches typically restrict exploration and can impede the developmental processes that come from dynamic interaction with the environment.
