Egocentrism in the context of learning mathematics refers to a child’s inability to differentiate between their own perspective and that of others. It is a cognitive characteristic often observed in early childhood, where children assume that others see, think, and feel the same way they do. Jean Piaget, a pioneering developmental psychologist, identified egocentrism as a key feature of the preoperational stage (ages 2 to 7). According to Piaget, children at this stage struggle to understand viewpoints different from their own, which affects their learning and reasoning abilities, including in mathematics. Piaget’s views on egocentrism suggested that young children are inherently self-centered in their thinking, which limits their capacity to engage in logical mathematical reasoning that requires understanding others' perspectives or abstract concepts. He believed that overcoming egocentrism is an essential developmental step that leads to the ability to think more logically and mathematically. However, Martin Hughes, a psychologist who studied children’s cognitive development, challenged some aspects of Piaget’s interpretation of egocentrism. Hughes thought that Piaget might have underestimated
