Which type of development involves thinking, reasoning, and problem-solving abilities?

The correct answer, cognitive development, refers to the advancements in mental processes such as thinking, reasoning, and problem-solving abilities. This area of development encompasses how individuals acquire knowledge, comprehend information, and apply their understanding to make decisions or solve problems. Cognitive development is crucial, especially in early childhood, as it lays the groundwork for learning experiences and intellectual growth throughout life.

In contrast, social development focuses on how individuals interact and form relationships with others, while emotional development pertains to understanding and managing one's feelings and the feelings of others. Physical development, on the other hand, relates to the growth and motor skills of the body. Each of these areas is important in their own right, but cognitive development specifically centers on the mental capabilities that enable logical thinking and intellectual engagement.
