"Cognitive" refers to processes related to thinking, understanding, learning, and remembering. It encompasses various mental activities, such as perception, attention, reasoning, and problem-solving. Cognitive functions are essential for daily tasks and decision-making, influencing how we interact with the world around us. In psychology, cognitive development is a key area of study, focusing on how individuals acquire and process knowledge over time. This field often examines theories proposed by figures like Jean Piaget and Lev Vygotsky, who explored how children develop cognitive skills through experiences and social interactions.
