Here are some theories related to cognitive development:
Jean Piaget: Piaget's theory of cognitive development is one of the most well-known perspectives on the subject. Piaget's theory is made up of three components:
Schemas: Building blocks that help us understand and interpret the world
The three processes of adaptation: Assimilation, accommodation, and equilibration
The four stages of cognitive development: Sensorimotor, preoperational, concrete operational, and formal operational

Cognitive learning theory: This theory focuses on internal mental structures and processes. It helps learners connect existing knowledge with new materials, leading to deeper insights.
Modern cognitive development theory: This theory emphasizes relationships, seeing social interaction as the crucible in which children's cognitive development takes place.
Lev Vygotsky's Theory of Child Development: This theory states that a child's cognitive development and learning ability can be guided and mediated by their social interactions.
