Child Psychology Test 2 Flashcards
(109 cards)
cerebral cortex
the outer, folded mantle of the brain, responsible for thinking, reasoning, perceiving, and all conscious responces
axon
a long nerve fiber that usually conducts impulses away from the cell body of a neuron
dendrite
a branching fiber that receives information and conducts impulses toward the cell body of a neuron
synapse
the gap between the dendrites of one neuron and the axon of another, over which impulses flow
synaptogenesis
forming of connections between neurons at the synapses. this process, responsible for all perceptions, actions, and thoughts, is most intense during infancy and childhood but continues throughout life
myelination
formation of a fatty layer encasing the axons of neurons. this process, which speeds the transmission of neural impulses, continues from birth into early adulthood
plastic
malleable, or capable of being changed (refers to neural or cognitive development)
sucking reflex
the automatic, spontaneous sucking movements newborns produce, especially when anything touches their lips
rooting reflex
newborns automatic response to a touch on the cheek, involving turning toward that location and beginning to suck
reflex
a response or action that is automatic and programmed by noncortical brain centers
undernutrition
a chronic lack of adequate food
stunting
excessively short stature in a child, caused by chronic lack of adequate nutrition
micronutrient deficiency
chronically inadequate level of a specific nutrient important to development and disease prevention, such as vitamin a, zinc, and or iron
food insecurity
worrying about not having enough food at the end of the month, or having to go Hungary due to lack of money
colic
a baby’s frantic continual crying during the first three months of life; caused by an immature nervous system
skin to skin contact
an effective calming strategy that involves holding a young infant next to a caregiver’s body
kangaroo care
carrying a young baby in a sling close to a caregiver’s body. used to sooth an infant
REM sleep
the phase of sleep involving rapid eye movements, when the leg looks almost like it does during waking. rem sleep decreases as infants mature
self- soothing
children’s ability, usually beginning at about 6 months of age, to put themselves back to sleep when they wake at night
co- sleeping
the standard custom, in collectivist cultures, of having a child and parent share a bed
sudden infant death syndrome (sids)
the unexplained death of an apparently healthy infant, often while sleeping, during the first year of life
preferential- looking paradigm
a research technique to explore early infant sensory capacities and cognition, drawing on the principle that we are attracted to novelty and prefer to look at new things
habituation
the predictable loss of interest that develops once a stimulus becomes familiar; used to explore infant sensory capacities and thinking
face-perception studies
research using preferential looking and habituation to explore what very young babies know about faces
