Child Psychology Test 2 Flashcards
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
fear bias
the human tendency to be hypersensitive to fearful facial cues that, by alerting us to danger, may prevent us from getting injured or killed
depth perception
the ability to see (and fear) heights
visual cliff
a table that appears to “end” in a drop-off at its midpoint; used to test infant depth perception
baby- proofing
making the home safe for a newly mobil infant
sensorimotor stage
Piaget’s first stage of development lasting from birth to age 2, when babies’ agenda is to pin down the basics of physical development
circular reactions
in Piagets framework, repetitive action oriented schemes (or habits) characteristics of babies during the sejnsorimeter stage
primary circular reactions
in Piagets framework, the first infant habits during the sensorimotor stage, centered on the body
secondary circular reactions
in Piagets framework, habits of the sensorimotor stage lasting from about 4 months of age to the babies first birthday, centered on exploring the external world
tertiary circular reactions
in Piagets framework “little scientist” activities of the sensor miter stage beginning around age 1 involving flexibility exploring the properties of objects
little- scientist phase
the time around age 1 when babies use tertiary circular reactions to actively explore the properties of objects, experimenting with them like scientists
means- end behavior
in Piagets framework, performing a different action to get to a goal - an ability that emerges in the sensorimotor stage as babies approach age 1
object permanence
in Piagets framework, the understanding that objects continue to exist even when we can no longer see them, which gradually emerges during the sensorimotor stage
a- not- b error
in Piagets framework, a classic mistake made by infants in the sensorimotor stage, whereby babies approaching age 1 go back to the original hiding place to look for an object even though they have seen it get hidden in a second place
information - processing approach
a perspective on understanding cognition that divides thinking into specific steps and component process, much like a computer
social cognition
any skill related to understanding feelings and negotiating interpersonal interactions
grammer
the rules and word arranging systems that every human language employs to communicate meaning
language acquisition device
Chomsky’s term for hypothetical brain structure that enables our species to learn and produce language
social - interactionist perspective
an approach to language development that emphasizes its social function, specifically that babies and adults have a mutual passion to communicate
babbling
the alternating vowel and consonant sounds that babies repeat with variations of intonation and pitch and that precede the first words
