Cognitive development refers to the changes over time in children's thinking, reasoning, use of language, problem solving, and learning, and children's approaches to interaction with their physical and social
environments.
Components of cognition include intelligence; arousal, orientation, attention, and executive function; memory (short and long term); information processing functions (such as pattern recognition, facial-emotional
content, imitation, cause-and-effect associations, processing multiple sources of information simultaneously); representational thought; and reasoning and concept formation (problem solving, language, perspective-taking, social context and rules).
For children age birth through two, cognitive development involves learning to coordinate sensory input with emerging motor skills, development of object permanence, differentiation of self from others, and emergence of representational thought and symbolic play.
How are my child's cognitive abilities tested?
Cognitive development is often assessed using standardized tests to derive a developmental quotient, mental
index, or intelligence quotient. For children under age three, cognitive development is measured using a developmental or mental index. Children who score significantly below average using a standardized test would be considered to have substantial limitations in cognitive functioning.
Cognitive impairments in very young infants and toddlers are generally associated with a diagnosed physical or mental condition with a high probability of resulting in developmental delay (e.g., central nervous system abnormalities, syndromes or conditions, etc.) and include deficits in one or more components of cognition.
