The four stages refer to the sequential cognitive development stages proposed by psychologist Jean Piaget, which children go through as they grow. These stages are characterized by distinct cognitive abilities and understanding of the world.
In this stage, infants explore and understand the world mainly through their senses and motor actions.
Children in this stage develop symbolic thinking and language skills but struggle with logical reasoning.
At this stage, children can think logically about concrete objects and events but have difficulty understanding abstract concepts.
