Which of the following is an aspect of intellectual development in childhood?

Improving reading and writing skills is a fundamental aspect of intellectual development in childhood. Intellectual development refers to the growth of cognitive abilities, which include thinking, learning, reasoning, and problem-solving skills. During childhood, children engage in activities that enhance their literacy capabilities, such as reading books and practicing writing. These skills are critical for academic achievement and overall cognitive growth, enabling children to understand and interact with the world around them better.

On the other hand, developing empathy relates more to emotional and social development, while attaining physical coordination falls under physical development. Forming intimate relationships ties into social relationships and emotional connection, marking those as areas outside the realm of intellectual development. Thus, improving reading and writing skills distinctly aligns with the overarching theme of cognitive growth during childhood.
