![]() ![]() Kenny’s pizza slice was cut into five pieces, so Kenny told his sister that he got more pizza than she did. For example, dad gave a slice of pizza to 10-year-old Keiko and another slice to her 3-year-old brother, Kenny. Children’s logic is based on their own personal knowledge of the world so far, rather than on conventional knowledge. Children also begin to use language in the preoperational stage, but they cannot understand adult logic or mentally manipulate information (the term operational refers to logical manipulation of information, so children at this stage are considered to be pre-operational). A child’s arms might become airplane wings as he zooms around the room, or a child with a stick might become a brave knight with a sword. In this stage, children can use symbols to represent words, images, and ideas, which is why children in this stage engage in pretend play. ![]() Piaget’s second stage is the preoperational stage, which is from approximately 2 to 7 years old. Infants who had already developed object permanence would reach for the hidden toy, indicating that they knew it still existed, whereas infants who had not developed object permanence would appear confused. Piaget studied infants’ reactions when a toy was first shown to an infant and then hidden under a blanket. According to Piaget, young infants do not remember an object after it has been removed from sight. Between 5 and 8 months old, the child develops object permanence, which is the understanding that even if something is out of sight, it still exists (Bogartz, Shinskey, & Schilling, 2000). Young children put objects in their mouths to see if the items are edible, and once they can grasp objects, they may shake or bang them to see if they make sounds. During this stage, children learn about the world through their senses and motor behavior. The first stage is the sensorimotor stage, which lasts from birth to about 2 years old. Understand concrete events and analogies logically perform arithmetical operations Use words and images to represent things, but lack logical reasoning World experienced through senses and actions Piaget’s Stages of Cognitive Development Age (years) He proposed a theory of cognitive development that unfolds in four stages: sensorimotor, preoperational, concrete operational, and formal operational. Like Freud and Erikson, Piaget thought development unfolds in a series of stages approximately associated with age ranges. He now modifies his schema for dogs and forms a new one for sheep. Blake’s schema for dog was too broad, since not all furry, four-legged creatures are dogs. When Blake’s mom tells him that the animal he sees is a sheep, not a dog, Blake must accommodate his schema for dogs to include more information based on his new experiences. One day, Blake sees a sheep for the first time and says, “Look mommy, dog!” Having a basic schema that a dog is an animal with four legs and fur, Blake thinks all furry, four-legged creatures are dogs. When Blake sees other dogs in his picture books, he says, “Look mommy, dog!” Thus, he has assimilated them into his schema for dogs. This process continues as children interact with their environment.įor example, 2-year-old Blake learned the schema for dogs because his family has a Labrador retriever. Accommodation describes when they change their schemata based on new information. First, they assimilate new information or experiences in terms of their current schemata: assimilation is when they take in information that is comparable to what they already know. When children learn new information, they adjust their schemata through two processes: assimilation and accommodation. By the time children have reached adulthood, they have created schemata for almost everything. Schemata are concepts (mental models) that are used to help us categorize and interpret information. Piaget said that children develop schemata to help them understand the world. Jean Piaget spent over 50 years studying children and how their minds develop. As we progress to a new stage, there is a distinct shift in how we think and reason. ![]() His theory of cognitive development holds that our cognitive abilities develop through specific stages, which exemplifies the discontinuity approach to development. However, he said that children do not think and reason like adults (Piaget, 1930, 1932). He believed that thinking is a central aspect of development and that children are naturally inquisitive. Instead of approaching development from a psychoanalytical or psychosocial perspective, Piaget focused on children’s cognitive growth. Jean Piaget (1896–1980) is another stage theorist who studied childhood development (Figure 1).
