Q

Why do we use these separate terms: speech, language and communication?

A

They are all separate areas of concern, although impairments in one area may affect the other.

A
  1. initiating/maintaining conversational topics
  2. clarifications
  3. turn taking
  4. matching communication style
  5. figurative language
  6. inferences.
20
Q

what is considered a “hallmark” of primary DLD?

A

grammar

21
Q

what is the most consistently reported finding in children with primary DLD?

A

They omit monophosyntactic markers of grammatical tense in spontaneous speech where morphemes are obligatory.
-omission of past tense, third person singular -s, copular form of the verb “be”
-

22
Q

One way to describe children with DLD is to say that their developmental level is significantly _______ than their chronological age.

A

lower than

23
Q

Should we use cognitive tests that involve the production or understanding of speech when testing children with DLD?

A

No

24
Q

what is nosology?

A

the branch of medical science dealing with the classification of diseases.

25
Q

what does DLD stand for?

A

developmental language disorder

26
Q

What makes a child more susceptible to DLD? (3)

A
  1. biological disposition
  2. pre or post-natal experiences
  3. chance events
27
Q

what are the levels of explanation for developmental language disorder?

A
  1. biological: (genetic influences)
  2. cognitive: (perception and information processing)
  3. behavioral: (overt behaviors)
  4. environmental (this can affect 1-3)
28
Q

Is DLD genetic?

A

it is thought possible, yet environments may have an affect too.

29
Q

which two areas within the inferior frontal gyrus form Brocas area?

A

par opercularis

pars triangularis

30
Q

what are the key structures important for auditory processing and language comprehension?

A

Wernickes (Heschel’s gyrus, superior temporal gyrus and planum temporale)

31
Q

What is the name of the fiber bundle that connects the frontal and temporal regions?

A

arcuate fasciculus

32
Q

what does the brain structure of DLD look like?

A
  1. atypical pattern of asymmetry of language cortex.
  2. abnormalities in white matter volume
  3. cortical dysplaisa
  4. additional gyri in frontal or temporal regions
33
Q

what techniques have been used to study the way children with primary DLD function differently. (2)

A
  1. fMRI

2. EEG (electrophysiological measures)

34
Q

what does a fMRI test?

A

brain activity in response to some external stimuli

35
Q

what does the EEG test?

A

firing of neurons in the brain in response to a specific external event

36
Q

Can environmental factors account solely to DLD?

A

no

37
Q

What are some environmental factors associated with DLD? (2)

A

socioeconomic status

multi-cultural societies

38
Q

Are auditory deficits a cause of DLD?

A

no

39
Q

auditory processing and other cognitive models of DLD generally take a __________ view of language processing

A

bottom-up

40
Q

What is the “bottom-up” view?

A

lower level processes (perception/discrimination), provide input necessary to the function of the high-level processing (comprehension)

41
Q

What will always influence how one processes input?

A

prior knowledge

42
Q

What is the conclusion to theoretical studies of DLD?

A

it is unlikely there is a single factor that would cause a variety of language profiles that are seen in DLD.

43
Q

What is comorbidity?

A

two or more disorders simultaneously

44
Q

children with ASD and DLD showed similarities in what 2 areas?

A

structural language (grammar and vocabulary)

45
Q

children with DLD were more likely to have _________ than ASD.

A

speech production and articulation

46
Q

How do children with ASD and DLD differ most greatly ?

A

social interactions and general communication
