“No single person has had a greater impact on the study of cognitive development than Jean Piaget” (Feldman, 2014, p. 19). Piaget’s Theory of Cognitive Development involves fixed stages of thinking. In each stage, thinking increases in quantity and quality. Thinking is categorized in what Piaget called schemes. In each scheme, he attributed assimilation and accommodation to changes in thought patterns. When a baby hears a dog bark and then points at a cow and says, “Woof”, the baby is assimilating the dog’s characteristics to the cow. However as the stage progresses, the toddler will learn to accommodate. He will learn that while both animals have four legs and fur, they are different. Assimilation and accommodation occur interchangeably throughout cognitive development. While Piaget’s Cognitive Theory is a cornerstone in developmental theories, there are questions. Researchers have found that some skills are acquired earlier that Piaget asserted. Also, the time frame of cognitive development has been found to be related to culture, and not as clear cut as Piaget presented it. (Feldman, 2014).
