Complex cognitive processes10/11/2023 ![]() The second stage is called primary circular reactions by Piaget and lasts to about 4 months of age. These schemas are beginning to be changed via accommodation. ![]() Occurring during the first month, the first substage focuses on schemas the infant is born with or as we called them in Module 3, reflexes. The sensorimotor stage has six substages. Have you ever noticed how young babies take genuine delight in putting everything in their mouths, but to the horror of their parents? This is evidence of the sensorimotor stage and thinking consists of coordinating sensory information with the movement of the body. You might say they think with their bodies and this stage lasts from birth to age 2. The sensorimotor stage is when infants focus on developing sensory abilities and learn to get around in their environment. We will cover each as they relate to how we learn, and update what we learn about our world. Piaget’s theory consists of four main stages - sensorimotor, preoperational, concrete operations, and formal operations. But cats and dogs are not the same and have one major difference - cats say ‘meow’ and dogs say ‘woof.’ So the child will update his/her schema for ‘dog’ to now include woof and creates a new schema for ‘cat’ which includes four legs, tail, furry, and meow. Why is that? The cat has four legs, a tail, and is furry. We would expect them to call the animal a dog. Let’s say a child meets a cat for the first time. Simply, when novel information is obtained, we could update an existing schema or create a brand new one. Second, we could use the process of accommodation. We interpret the world in terms of our current schemas and understand anything novel similar to this existing way of understanding experience. Notice the word similar within assimilation. First, assimilation is when new information is made to fit into existing schemas. Piaget said that these schemas change due to direct experience with our environment a process he called adaptation. We have a schema for ‘dog’ which includes the ideas of four legs, a tail, and being furry. ![]() First, schemas are organized ways of making sense of experience. Before we get into it, it is important to explain a few key concepts he proposed. Swiss psychologist, Jean Piaget (1896-1980), proposed a stage theory of how cognitive development proceeds.
