Which of the following is a key sign of cognitive development in 4-year-olds?

In 4-year-olds, a significant indicator of cognitive development is their ability to use symbols and language in play. At this age, children engage in symbolic play, which is an essential component of cognitive growth. They begin to use objects to represent other things—like using a block as a car or a doll as a baby—showing that they can think abstractly and manipulate concepts in their mind.

Additionally, their language skills are rapidly advancing, allowing them to express their thoughts, ideas, and emotions more clearly. This interplay between symbolic use and language is critical, as it facilitates creativity and enhances their social interactions during play.

While logical thinking, drawing conclusions, and understanding time and sequencing are also parts of cognitive development, they typically become more pronounced in later stages, such as when children reach the age of 5 or 6. At 4 years old, the focus is more on imaginative and symbolic representation, making the use of symbols and language in play a primary hallmark of cognitive development at this age.
