What is the sensorimotor stage of cognitive development?

Answer 1

According to Piaget, the sensorimotor stage of development is the first stage that a child will pass through. This stages begins at birth and lasts, approximately, until the age of two. During this stage, the infant gains information about the world through his or her senses and motor movements. He/she constructs the world by tasting, banging, grasping, etc. By the end of this stage, he/she is beginning to understand cause/effect relationships and object permanence, and will also have developed essential spacial abilities.

Answer 2

The first stage of Piaget's theory lasts from birth to approximately age two and is centered on the infant trying to make sense of the world. During the sensorimotor stage, an infant's knowledge of the world is limited to their sensory perceptions and motor activities. Behaviors are limited to simple motor responses caused by sensory stimuli. Children utilize skills and abilities they were born with, such as looking, sucking, grasping, and listening, to learn more about the environment.

Substages of the Sensorimotor Stage:

The sensorimotor stage can be divided into six separate substages that are characterized by the development of a new skill.

Reflexes (0-1 month):

During this substage, the child understands the environment purely through inborn reflexes such as sucking and looking.

Primary Circular Reactions (1-4 months):

This substage involves coordinating sensation and new schemas. For example, a child may such his or her thumb by accident and then later intentionally repeat the action. These actions are repeated because the infant finds them pleasurable.

Secondary Circular Reactions (4-8 months):

During this substage, the child becomes more focused on the world and begins to intentionally repeat an action in order to trigger a response in the environment. For example, a child will purposefully pick up a toy in order to put it in his or her mouth.

Coordination of Reactions (8-12 months):

During this substage, the child starts to show clearly intentional actions. The child may also combine schemas in order to achieve a desired effect. Children begin exploring the environment around them and will often imitate the observed behavior of others. The understanding of objects also begins during this time and children begin to recognize certain objects as having specific qualities. For example, a child might realize that a rattle will make a sound when shaken.

Tertiary Circular Reactions (12-18 months):

Children begin a period of trial-and-error experimentation during the fifth substage. For example, a child may try out different sounds or actions as a way of getting attention from a caregiver.

Early Representational Thought (18-24 months):

Children begin to develop symbols to represent events or objects in the world in the final sensorimotor substage. During this time, children begin to move towards understanding the world through mental operations rather than purely through actions.
