15 25 of young children have some type of communication disorder
15-25% of young children have some type of communication disorder

  • Incidence of SLI (specific language impairment)

    in 5 y. old was estimated to be 7,6%

    National Institutes of Health – USA

    (a condition also called language-learning impairment, developmental dysphasia, developmental language disorder or dev. aphasia.

  • Late talkers - most 67% to 84% are boys

    (if a child has SLI, there is a 25% chance that another family member will be affected…)

  • Dysarthria, verbal apraxia, phonological disorder

  • Suttering – fluency disorders

  • Cleft palate

Timing of developmental milestones for language
Timing of developmental milestones for language disorder

  • Vowel sounds

  • Localizes sounds

  • Babbles

  • First words 12 month

  • Follows one-step commands with gesture 12 m.

  • Follows one-step commands without gesture 17 m.

  • Follows two-step commands 24 m.

  • Uses two- or three-word phrases 24 m.

  • Uses pronouns

  • Says name, age, gender 3,5 y.

  • Can carry on conversations using adult-like grammar with 100% speech clar

  • Can talk about past, future,, and imaginary events 5 y.

Absolute indications for immediate evaluation of language delay
Absolute indications for immediate evaluation disorderof language delay

  • No babbling, pointing, or gesturing

    by 12 months

  • No single words

    by 16 months

  • No two-word spontaneous phrases

    by 24 months

  • Any regression in language or social skills at any age

The heterogenity of sli specific language impairment
The heterogenity of SLI disorder(specific language impairment)

  • Sprachentwicklungstörungen (SES) Developmental dysphasia

    Developmental language disorders (DLD)

  • At the heart of SLI is an disorder of auditory perception

  • Central auditory deficits may result in/or coexist with difficulties in other CNS-based skills: as speech-language impairment, attention defecot, developmental and learning disabilities

Auditory phonological processing presents the heterogenity of specific language impairment sli

Identification of speech sounds appears to be a problem disorder

More typical SLI – where language comprehension is impaired, but the most

obvious problems are with expressive syntax and phonology

Problems with semantic and association function

Disorder of the short-time memory

Auditory processing deficit – inability to recognize the key words

Inabilty to use intrinsic- extrinsic redundancies to complete speech sound

Auditory-phonological processingpresents the heterogenity of specific language impairment (SLI)

Developmental dysphasia developmental dysphasia stuttering developmental dysphasia dysarthria
Developmental dysphasia disorderDevelopmental dysphasia + stutteringDevelopmental dysphasia + dysarthria

Results of mentioned study of children with sli
Results of mentioned study disorderof children with SLI

  • Positive family history in 185 children

  • Positive perinatal history in 145 children

  • Disorders of phonemic discrimination

    in 223 children

  • Phonological, lexical and syntactic deficits

  • LAEPs with prolonged latency of wave P3

  • EEG abnormalities

  • Integration deficit in dichotic listening

Phonological awareness n 300

Children central auditory disorders comprehensive central auditory assessment
Childrenś central auditory disorders – comprehensive central auditory assessment

  • CAPD (central auditory processing disorder) is an auditory processing deficit caused by deficiency in skills that are subserved by the Central auditory mechanism in the brainstem and brain and include (ASHA 1996):

    sound localization and lateralization,

    auditory discrimination and pattern recognition,

    temporal resolution-masking-integration-ordering, ability

    to identify or recognize degraded or competing targets

Central auditory deficits
Central auditory deficits central auditory assessment

  • Auditory Decoding Deficit – they do not „hear“ (the „what“ child) poor discrimination of fine acoustic differences in speech

  • Integration Deficit - reflects delayed or abnormal interhemispheric communication

  • Prosodic Deficit – deficiency in ability to use prosodic features of target (it is all „too fast“)

  • Auditory Associative deficit – not applying rules of language to acoustic signal

  • Output-Organization deficit – behavioral manifestation of impaired efferent function or planning

Central auditory tests dichotic speech tests
Central auditory tests central auditory assessmentDichotic speech tests

  • auditory stimuli presented to both ear simultaneously+being different

  • The aim of study:

  • to analyse the role of auditory perception in children with developmental dysphasia using speech (dichotic) central tests

  • The experimental tasks consisted of 3 auditory measures (test 1-3): dichotic listening of two-syllabic target words presented like binaural interaction tests

Children with sli dichotic listening disability to synthesize 2 two syllabic words
Children with SLI - dichotic listening central auditory assessmentDisability to synthesize 2 two-syllabic words

Dichotic listening central auditory assessmentthe average number of correct responses was significantly lower in SLI children than in children from control group

Statistical analysis paired t test confirmed significant differences p 0 001
Statistical analysis (paired t-test) central auditory assessmentconfirmed significant differences: p - 0,001

Conclusions central auditory assessment

  • A longitudinal study was conducted to document and compare the evolution of children with linguistic acquisition impairment

  • Our results indicate the relationship between specific language impairment and central auditory processing disorder

  • The expressive disturbancies are a manifestation of decoding impairment in children with SLI

  • With an auditory training improve language abilities

Conclusions central auditory assessment

  • Recently, classification according to the perception deficit also occurred within the framework of non-uniform terminology in the area of developmental speech-language disorders.

  • The relationship between damaged speech comprehension and the deficit in speech expression has been sought, in which case the speech expressive disorders represent manifestation of worsened decoding of input acoustic information.
