The first of four stages of cognitive development identified by Piaget. Sensorimotor actions consist of integrations of the sensory and motor aspects of organised actions. In Piaget‚was theory, infants are capable of sensorimotor action, but not thought. Thought requires the ability to represent images of objects or events in the absence of direct action on those objects. In sensorimotor action, an infant is capable of representing an object only when receiving sensory input from that object
