First Three Years Flashcards
Central Nervous System
brain and spinal cord
Lateralization
tendency of each of the brain’s hemispheres to have specialized functions
Neurons
nerve cells
Integration
process by which neurons coordinate the activities of muscle groups
Differentiation
process by which cells acquire specialized structure and function
Cell Death
in brain development, normal elimination of excess cells to achieve more efficient functioning
Myelination
process of coating neurons with myelin, a fatty substance that enables faster communication between cells
Reflex Behavior
automatic, involuntary, innate response to stimulation
Systems of Action
increasingly complex combinations of motor skills that permit a wider or more precise range of movement and more control of the environment
Denver Developmental Screening Test
screening test given to children age 1 month to 6 years to determine whether they are developing normally
Gross Motor Skills
physical skills that involve the large muscles
Fine Motor Skills
physical skills that involve the small muscles and eye-hand coordination
Visual Gudiance
use of the eyes to guide movements of the hands or other parts of the body
Depth Perception
ability to perceive objects and surfaces in three dimensions
Haptic Perception
ability to acquire information about properties of objects, such as size, weight, and texture, by handling them
Visual Cliff
apparatus designed to give an allusion of depth and used to assess depth perception of infants
Ecological Theory of Perception
theory developed by Elanor and James Gibson that describes developing motor and perceptual as interdependent parts of a functional system that guides behavior in varying context
Dynamic Systems Theory
Thelen’s theory that holds that motor development is a dynamic process of active coordination of multiple systems within the infant in relation to the environment
Infant Mortality Rate
proportion of babies born alive who die within the 1st year
SIDS
sudden and unexplained death of an apparently healthy infant
Nonorganic Failure to Thrive
in infancy, a lack of appropriate growth for no known medical cause, accompanied by poor developmental and emotional functioning
Shaken Baby Syndrome
form of maltreatment in which shaking an infant or toddler can cause brain damage, paralysis, or death
Behaviorist Approach
approach to the study of cognitive development that is concerned with the basic mechanics of learning
Psychometric Approach
approach to the study of cognitive development that seeks to measure the quantity of intelligence a person possesses
Piagetian Approach
approach to the study of cognitive development that describes qualitative stages in cognitive functioning
Information-Processing Approach
approach to the study of cognitive development by observing and analyzing processes involved in perceiving and handling information
Cognitive Neuroscience Approach
approach to the study of cognitive development that links brain processes with cognitive ones
Social-Contextual Approach
approach to the study of cognitive development that focuses on environmental influences, particularly parents and other caregivers
Intelligent Behavior
behavior that is goal oriented and adaptive to circumstances and conditions of life
IQ Tests
psychometric tests that seek to measure intelligence by comparing a test-taker’s performance with standardized norms
Bayley Scales of Infant and Toddle Development
standardized test of infant’s and toddler’s mental and motor development
Home Observation for Measurement of the Environment
instrument designed to measure the influence of the home environment on children’s cognitive growth
Early Intervention
systematic process of providing services to help families meet young children’s developmental needs
Sensorimotor Stage
in Piaget’s Theory, first stage in cognitive development, during which infants learn through senses and motor activity
Circular Reactions
Piaget’s term for processes by which an infant learns to reproduce desired occurrences originally discovered by accident
Representational Ability
Piaget’s term for capacity to store mental images or symbols of objects and events
Visible Imitation
imitation with parts of one’s body that one can see
Invisible Imitation
imitation with parts of one’s body that one cannot see
Deferred Imitation
Piaget’s term for reproduction of an observed behavior after the passage of time by calling up a stored symbol of it
Elicited Imitation
research method in which infants or toddlers are induced to imitate a specific series of actions they have seen but not necessarily done before
Object Permanence
Piaget’s term for the understanding that a person or object still exists when out of sight
