The term "sensorimotor" refers to the integration of sensory input and motor output in the development of skills and behaviors. It is a crucial stage in cognitive development, particularly in infants, where they learn to understand the world through their senses and actions. This process involves exploring their environment, manipulating objects, and responding to stimuli, which helps build their understanding of cause and effect. In psychology, the sensorimotor stage is the first of Jean Piaget's four stages of cognitive development, occurring from birth to about two years of age. During this time, infants develop basic motor skills and learn to coordinate their movements with sensory experiences. This foundational stage is essential for later cognitive growth and the development of more complex thinking abilities.
