The document defines key terms related to child development and cognitive processes in infants and toddlers. It describes Piaget's stage of sensorimotor intelligence where infants use senses and motor skills to understand the world through processes like habituation, primary and secondary circular reactions, and tertiary circular reactions involving experimentation. It also defines concepts like object permanence, naming explosion, deferred imitation and the "little scientist" stage of toddlers.
