Q

Definition of “language”

A

ASHA: “complex and dynamic system of conventional symbols that are used in various modes for thought and communication.”
- a rule-governed behavior
“ It is defined as the comprehension and/or use of a spoken (i.e., listening and speaking), written (i.e., reading and writing), and/or other communication symbol system (e.g., American Sign Language).

Q

a code is..

A

the translation of 1 type of information into another

  • relationship between a word and its reference is arbitrary
  • we must follow specific rules to organize words in sentences
    ex: happy translate to a feeling

Q

the language system is ..

A

dynamic- in a state of activity and change always
change occurs when
- when a person is acquiring language
- when a community uses a certain leanguage
—– they add or get rid of words they use or don’t use

Q

speech

A

“The neuromuscular process by which language is turned into a sound
signal and transmitted to a receiver”
has 4 system of respiration,phonation,resonance and articulation
- used to share language, writing, reading and singing
*** Speech depends on language bc lang give speech its meaning

on speech bc language can be shared by other means

speech and language are largely independent process

Q

hearing

A

sensory system that allows speech to enter into and be processed by the brain
- essential to reception and comprehension of spoken lang
2 types: general auditory perception (you cant tell what it is) and speech perception (diff sounds of letters)

Q

transmission and reception of speech

A

involvees 4 acoustic events

  • creating of sound
  • vibration of air particles : frequency, pitch and ntnesity/ oudness
  • reception by the ear 3-3 chamber outer,middle , inner
  • comprehension by the brain (left hemisphere)

Q

speech percetion

A

how the brain processes SPEECH and language

  • involves processing phonemic info
  • not necessarily sequential bc od co articulation
  • phonemes overlap with one another when humans produce speech

A

Q

reception:

A

receiving the info

25
transmition
conveying ideas
26
comprehension
make sense of info
27
communication can be...
- symbolic: specific entity and relatinship between the entity and reference - preintentional: assume the relationship between a behavior and its reference - intentional: relationship between the behavior and reference is not arbitrary
28
people share info to..
request reject comment
29
oral communication
the ocmbination of speaking and listening
30
model of communication
- sender formulates and transmits message - receiver receives and comprehends - shared symbolic means for communication
31
feedback makes
communication active and dynamic | effective communication
32
linguistic feedback:
involves speaking
33
nonlinguistic feedback:
use of eye contact, facil expressions, posture and proximity
34
paralinguistic feedback
pitch,loudness and pausing
35
major purposes of communication:
instrumental, regulatory, interaction, personal, heuristic, imaginative and informative
36
major domains of language
form: how words, sentences nad sound are organized content: the words used and their meaning use: how people draw on language functionally to meet needs
37
5 component system
``` phonology morphology syntax semantics pragmantics ```
38
phnonlogy
rules of a language governing the sounds that make syllables and words 39 phones in English
39
morphology
rules of language governing the internal organization of words - allows us to add specificity to language - allows us to expand vocab exponentially by using a small core of words - grammatical morpheme include plural
40
syntax
governs the internal organization of snetences
41
semantics
governs the meaning of individual words and word comnications - allows meaning of words, how many meaning a word has and wherether meaning are literal or figurative
42
pragmatics
governs language use for social purposes - social communication using lang for different functions or intentions knowing what to say and when and how to say it
43
allophones
subtle variations of phonemes due to context
44
phonotactics:
eahc language has their rules governing how sounds are organized
45
remarkable features of language
``` acquisition rate universality species specificity semanticity productivity ```
46
acquisition rate
Within 1 year of birth, children begin to understand and use several words • By 24 months, they have a vocabulary of several hundred words and can combine them into short sentences • Birth to puberty is called a critical period for language development
47
universality
Suggeststhatallpersonsaroundtheworldapplythesame cognitive infrastructure to learning language • Thisinfrastructureisparticularlysuitedtodeveloping symbolic representations for objects and actions • Thewaychildrenlearnlanguageandthetimeframesfor milestones are relatively invariant across the globe
48
semanticity
Alsocalleddisplacement • Allowspeopletorepresenteventsthataredecontextualized to share what happened before this moment or that may happen in the future • Allowspeopletorepresenttheworldtoothers
49
productivity
Theprincipleofcombination;thatasmallnumberof discrete units can be combined into seemingly infinite creations • Youcanproduceasentencenoonehaseveruttered • Nonhumancommunicationsystemscannotberecombined to make new meanings
50
language differneces and language disorders

language learning environment
Neuralarchitecturethatsupportslanguageacquisitionis calibrated in the basis of input from the environment • Thequantityandqualityoflanguageexperiencedare important factors • Howoftentoddlersandpreschoolersparticipatein conversation with caregivers is associated with language growth in the first few years of life Caregiverresponsiveness(promptness,contingency,and appropriateness) is important • Highercaregiverresponsivenessisassociatedwith accelerated rates of language development
55
language disorders
result of heritable langiage impairment developmental disability brain injury
56
heritable langiage impairment
Exhibitdepressedlanguageabilities,typicallywithno other concomitant impairment of intellect • Oftencalledspecificlanguageimpairment(SLI) • Affectsabout7-10%ofchildren • SLIisthemostcommontypeofcommunicationimpairment in children
57
developmental disability
Languagedisorderissecondary • Commoncausesareintellectualdisability(ID)andautism spectrum disorder (ASD) • 1in68childrenhaveASD • ChildrenwithASDusuallyexhibitmildtoprofound language impairment; some never develop productive language Socialcommunicationdisorder(SCD)orpragmatic communication disorder is related to ASD • Historically,individualswithSCDhavebeenreferredtoas having “high functioning ASD” but now is considered separate from autism.
58
brain injury
can occur in uteor and perinatally or can be acquired physical trauma called traumatic brain injuries injuries can be diffuse or focal damages areas of the brain are applied to complex skills and activities
