according to this model, the brain areas work together for higher level functions including language
connectionist model
layer consisting of myelinated axons
white matter (outside)
layer consisting of non-myelinated axons
gray matter (inside)
cushioning structure for the brain
cerebrospinal fluid
outer most membrane of cerebrum
durameter
located in-between duramater and piameter
arachnoid
convolutions or elevations observed within the brain surface
gyri (gyrus)
innermost layer of cerebrum
piameter
grooves or valleys observed within the brain surface
sulci (sulcus)
blood supply or information sent to the same side of the brain
ipsilateral innervation
blood supply or information is sent to the opposite side of the brain
contralateral innervation
divides brain into right and left hemispheres
longitudinal fissure
connects the right and left hemisphere
corpus callosum
divides the brain into anterior and posterior halves
central sulcus
important for speech, language and hearing
lateral cerebral fissure a.k.a Sylvian fissure
cerebellum has ____ cerebellar hemispheres
two
each cerebellar hemisphere has _____ lobes
three
what are the three cerebellar hemisphere lobes?
anterior, posterior, flocculondular
lexical knowledge
semantics
which area is typically important for forming grammatically correct sentences?
brocas area
the flexibility of the central nervous system to generate new synaptic connections and/or develop alternate connections to execute life functions
neural plasticity
this type of plasticity happens during early childhood
experience-expectant plasticity
this type of plasticity continues throughout life
experience-dependent plasticity
______ research focuses on generation and refinement of existing knowledge base
basic
_______ research focuses on addressing specific problems related to different concepts
applied
these theories are based on the fact that humans are born with language skills
nature inspired theories
Language is innate to humans and there are specific areas of the brain that control specific language functions
fodor’s modularity theory
Children do not have any innate knowledge about language. They learn language through environmental stimulation and reinforcement of vocalizations by adults.
behaviorist theory (skinner)
_______ conditioning is when behaviors become stronger when they are reinforced and they become suppressed when they are punished.
operant
humans learn language through both a combination of nature and nurture-related factors
interactionist theories
Language is unique to humans. Language typically emerges from social interactions with peers and adults.
Vygotsky’s social-interactionist theory
The zone of ________ ________focuses on this possible potential level where a child may be able to learn or demonstrate new skills by some more assistance or scaffolding.
proximal development
Language is learned due to cognitive and social skills. Children’s cognitive development occurs before language development.
piaget’s cognitive theory
A stage in language development where children are very self-centered and they usually talk about the things related to them.
egocentric speech
These are ideas that govern language processing and the role of tangible rewards that the speaker gains through language use.
cognitive principles
These are related to an individual’s confidence in language learning and one’s inclination to take risks with respect to language.
affection principles
These are principles that suggest that knowledge of other languages may either facilitate or interfere in learning new languages.
linguistic princples
intonation is the _________ placed on certain syllables at phrase and sentence level
prominence
length of the sounds at word level
duration
prominence placed on certain syllables of multisyllabic words
stress
strong-week stress pattern
TEACHer, CHIna
weak-strong stress patter
aBOVE, jaPAN
Process by which infants begin to focus more on perceptual differences that are of significance to them.
perceptual narrowing
During the first year of life, infants are able to process phonetic information for both native and non-native languages
phonetic processing
These are rules for use of speech sounds in a language
phonotactic regularities
variations of a speech sound which may or may not indicate a change in meaning
allophones
voice ______ time: time in-between the release of a stop consonant and the onset of vocal fold vibration
onset
superordinate level
most general concepts in a particular category. examples: people, animal, food
basic level
general words within a category. examples: mama, dada, water
subordinate level
specific examples of basic level words. examples: types of apples, gala, granny smith, red delivious
by what age do infants begin to differentiate between living and non-living things?
4 months
these categories include concepts arranged on the basis how and what the objects are used for
conceptual categories (examples: cup is for drinking, spoon is for eating)
