Toddlerhood Flashcards
what is the protein deficiency in childhood, leading to symptoms such as lethargy, irritability, thinning hair and swollen body, which may be fatal if not treated
Kwashiorkor
dietary ingredients essential to optimal
physical growth, including iodine, iron, zinc
and vitamins A, B12, C and D
micronutrients
density of synapses among neurons in the
brain; peaks around age 3
synaptic density
process of reducing number of connections
between neurons so that they become moreefficient
synaptic pruning
a device that measures the electrical activity of the cerebral cortex, allowing researchers to measure overall activity of the cerebral cortex as well as activation of specific parts
EEG (electroencephalogram)
method of monitoring brain activity in which a person lies inside a machine that uses a magnetic field to record changes in blood flow and oxygen use in the brain in response to different kinds of stimulation
fMRI (functional magnetic resonance
imaging)
Piaget’s final stage of sensorimotor
development in which toddlers first think
about the range of possibilities and then
select the action most likely to achieve the
desired outcome
mental representations
ability to repeat actions observed at an
earlier time
deferred imitation
difference between skills or tasks that
children can accomplish alone and those they are capable of performing if guided by an adult or a more competent peer
zone of proximal development
in Vygotsky’s theory, self-guiding and selfdirecting comments children make to
themselves as they learn in the zone of
proximal development
private speech
degree of assistance provided to the learner in the zone of proximal development, gradually decreasing as the learner’s skills develop
scaffolding
teaching interaction between two people
(often an adult and a child) as they
participate in a culturally valued activity
guided participation
ability to take the word symbols of a
language and combine them in a virtually
infinite number of new ways
infinite generativity
portion of the left frontal lobe of the human brain that is specialised for language production
Broca’s area
portion of the left temporal lobe of the human brain that is specialised for language comprehension
Wernicke’s area
according to Chomsky, innate feature of the brain that enables children to perceive and grasp quickly the grammatical rules in the language around them
language acquisition device (LAD)
single word that is used to represent a whole sentence
holophrase
use of a single word to represent a variety of related objects
overextension
applying a general word to a specific object
underextension
learning and remembering a word for an
object after just one time of being told what the object is called
fast mapping
two-word phrases that strip away connecting
words, such as the and and
telegraphic speech
applying grammatical rules even to words
that are exceptions to the rule
overregularisation
Toddlerhood emotional self-regulation - 4 types
behaviours, language, external requirements, sociomoral emotions
emotions evoked based on learned, culturally based standards of right and wrong; also called secondary emotions
sociomoral emotions
