Wk. 2 - Infancy and Early Childhood - Ch. 3 - Physical and Cognitive Development in Infancy Flashcards
cephalocaudal pattern
sequence in which the earliest growth always occurs at the top — the head — with physical growth in size, weight, and feature differentiation gradually working from top to bottom.
proximodistal pattern
sequence in which growth starts at the center of the body and moves toward the extremities.
lateralization
specialization of function in one hemisphere of the cerebral cortex or the other.
neurons
Nerve cells that handle information processing specialized cells that transmit nerve impulses.
myelinization
process of encasing axons with fat cells, begins prenatally and continues throughout childhood, even into adolescence.
neuroconstructionist view
Developmental perspective in which biological processes and environmental conditions influence the brain’s development; the brain has plasticity and is context dependent; and cognitive development is closely linked with brain development.
REM sleep (Rapid Eye Movement)
Rapid eye movement sleep is a unique phase of sleep in mammals and birds; characterized by random rapid movement of the body, and the propensity of the sleeper to dream vividly.
sudden infant death syndrome (SIDS)
A condition that occurs when an infant stops breathing.
gross motor skills
Motor skills that involve a large-muscle activity such as walking.
fine motor skills
Motor skills that involve more finely tuned movements, such as finger dexterity.
sensation
The product of the interaction between information and the sensory receptors — the eyes, ears, tongue, nostrils, and skin.
perception
The interperception of what is sensed.
ecological view
The view that perception functions to bring organisms in contact with the environment and to increase adaptation.
visual preference method
A method developed by Fantz, to determine whether infants can distinguish one stimulus from another by measuring the length of time they attend to different stimuli.
habituation
Decreased responsiveness to a stimulus after repeated presentations of the stimulus.
dishabituation
Recovery of a habituated response after a change in stimulation.
eye-tracking
The process of measuring either point of gaze (where one is looking) or the motion of an eye relative to the head.
