Q

What age do we diagnose specific language impairment (SLI) and why?

A
  • SLI may be diagnosed after the age of 4

- To avoid diagnosing a child who may be a “late bloomer”

Q

Why SLI is called a heterogeneous disorder

Study These Flashcards
A

Each child with SLI is going to present with their own set of unique set of difficulties in a bunch of combinations in the area of language: semantics, syntax, morphology, and pragmatic language behaviors

25
What percentage of children with phonological disorders also have difficulties with language?
40-70%
26
Unusual phonological processes children with SLI might produce
- Prevocalic devoicing | - Word-initial weak syllable deletion
27
- May be slow to acquire their first words - May not show the explosive increase in vocabulary typical for 18-24 months - May persistent in overextension and underextension - Slower to attain 2-word combinations - Difficulty with abstract concepts - Receptive skills higher than expressive
deficits in the semantic component of language exhibited by children with SLI
28
What areas of language are most affected by SLI
Syntax and morphology
29
- Sentences spoken are short and lack complexity - Omission of function words (articles, prepositions) resulting in telegraphic speech - Older children with SLI may have particular difficulty with production of complex sentences with introductory or embedded dependent clauses
deficits in the syntactic component of langauge exibited by children with SLI
30
What is the most promising clinical marker of SLI?
Morphological deficits
31
``` Regular plural–s Possessive –s Present progressive –ing Third person singular present tense –s Auxillary verb Copula verbs Past tense –ed Irregular plurals Irregular past tense verbs ```
inflectional morphemes children with SLI may have difficulties with
32
ducks, chairs
Regular plural–s
33
Daddy’s hat
Possessive –s
34
“The dog is running.”
Present progressive –ing
35
"She plays the piano."
Third person singular present tense –s
36
“He is running.”
Auxillary verb is/was
37
“I am a teacher.”
Copula verbs am/you
38
“He talked to me yesterday.”
Past tense –ed
39
feet, mice, children
Irregular plurals
40
ate, went, swam
Irregular past tense verbs
41
Proposed explanations for morphologic deficiencies in children with SLI
- Explanations involving perception - Explanations involving syntactic complexity - Explanations involving syntactic redundancy
42
- Reduced appropriate social skills - Fewer peer relationships than age-matched peers - A limited amount of comments relating to events/people - Limited interactions - Limited use of gestures - Inappropriate turn-taking - Expression of inappropriate comments - Absence of conversational repair - Difficulties in: describing, initiating, maintaining topics, narrative abilities, peer interactions
deficits in pragmatic language skills might be seen in children with SLI
43
How strong a diagnostic marker is the area of pragmatics for SI?
No a strong diagnostic marker compared to syntax and morphology
44
- Students may be perceived in a more negative light by students or peers - Young children may exhibit behavioral problems - Children are less participatory in early elementary school - May have negative self-view - Low self esteem
Emotional consequences of SLI
45
The limitations of correlation data
Must be viewed with caution | Correlation is not causation
46
The two major types of genetic studies
Population genetic studies | Molecular genetics
47
The three types of population genetic studies
Family studies Pedigree studies Twin studies
48
The basic findings regarding the KE family and the FOXP2 gene
Found that the FOXP2 gene was the “talking gene” due to the KE family pedigree study; but later finding suggested that the gene is not involved in language disorders
49
Findings of Plante et al. (1991)
Conducted an autopsy study on 4 males with “developmental dyslexia” and found that the two sides were symmetrical due to typically sized left but an oversized right
50
Less interaction More directive statements Less questions More shouting and threatening
Description of the quality of interactions between mothers and their children with SLI
51
Effects of socioeconomic status (SES) on language and literacy
Low SES is correlated with poor language and literacy skills in children
52
The manner in which Hart and Risley conducted their study
A longitudinal study; observed 13 families (13 high SES, 23 mid SES, 6 low SES); monthly hour-long observations in home for 2 and ½ years; trial started hen target child was 8-9 months; data written down and recorded; 1,318 transcripts took an additional 3 years to develop a computer program
53
Quantitative and qualitative differences in the manner in which children were exposed to language, as discovered by Hart and Risley (1995): Quantitative-
- Number of words addressed to the child in accordance with their SES (high mid low) - The higher the amount of language expressed to the child the better the language and vice versa
54
Quantitative and qualitative differences in the manner in which children were exposed to language, as discovered by Hart and Risley (1995): Qualitative-
- Encouragements and discouragements towards children in accordance with their SES (high mid low) - There more encouragements toward a child with high SES - There were more discouragements towards children in accordance with low SES
55
``` Complex reasoning asks Information processing skills Memory skills Haptic (touch) perception Attentional deficits and hyperactivity Symbolic play activity ```
Underlying deficits researchers have suggested exist in children with SLI
56
- Results in improved expressive language skills - Is necessary before one can train expressive language skills - Makes direct language training more efficient
What treatment research evidence suggests about underlying deficit training when treating children with SLI
57
Reed’s conclusion about SLI
It’s prevalence rate makes it the most frequently occurring of all communication disorders, and it is one of the “most commonly occurring neurodevelopmental disorders”
58
Operates in which case those children who are better at language are better able to take advantage of language-learning opportunities to learn more language, but those who are not good fall further behind and the gap between the language able and language limited children widens with time
Matthew effect
59
There is increasing evidence that children with delayed expressive language development who also have more notable comprehension deficits are likely to demonstrate porter outcomes, even into adolescence
Why comprehension skills deserve some special mention:
