Q

If we create sub-groups –should we be doing different therapies?

A

YES. No single treatment is appropriate for such a diverse population.
Different sub-groups = Different treatment / Sequence of treatments/diff outcomes to Tx

What is an SSD?

A

Speech sound Disorder (SSD) : SSD encompasses a range of children’s (adult’s) speech production disorders including those arising from linguistically-based difficulties (i.e., a phonological disorder), and/or production related articulation disorders (i.e., phonetic disorders).

Q

One explanation of atypical processes is fluctuating hearing loss due to Otitis media + effusion which makes it difficult to reliably identify the relevant _______________ and thus establish correct place for obstruents (stops/fricatives) and may alternatively use a more _______ tongue placement.

> What is this explanation called

A

> perceptual cues

> posterior (i.e. backing)

Q

What is the Linguistic explanation of backing (constraint based approach)

A

Backing involves adding a marked feature (+dorsal) which is phonologically impossible (due to constrains and violations).

This only happens when the child has a very unusual (atypical) phonological system in which Dorsal is the default place feature.

Q

What is the motor explanation of backing?

A

Poorly differentiated/timed lingual gestures with tongue (also affects lateral distortions of sibilants - tongue sides are lowered and air flows out sides of tongue causing a lisp )

Q

A chid displaying variable productions of same phonemes within the same context (lacks stable phonological system) and a deficit in phonological planning is classified as what SSD

A

Inconsistent (Deviant) Phonological Disorder

22
Q

True or false a child with Inconsistent (Deviant) Phonological Disorder will have phonological awareness (Rhyme, aliteration) similar to typically developing peers

A

TRUE - a child with this SSD has intact phonological representation, phonetic planning ability, and motor speech implementation.

> PHONOLOGICAL planning is where the impairment occurs

23
Q

An inability to produce a perceptually acceptable version of particular phonemes, either in isolation or in any phonetic context would classify a child as having an…

A

Articulation disorder

24
Q

In children with Articulation disorder the Wrong _________ for production of specific sound has been learned but their ________ and _______ systems are intact!

A

motor program

> Intact cognitive-linguistic and Phonological systems

25
Q

In with SSD do we find single speech sound distortions, errors, or omissions such as [r], [l] and [s] distortions, Lateral lisp
Or substituting one phoneme for another ([w] for /r/) - aka gliding

A

Articulation disorder (Typically errors do not greatly impact overall intelligibility)

26
Q

The motor template for a particular sound is within the proper phoneme category (i.e., _____________ accurate) but is imprecise in the detailed specifications for the sound output (i.e., ___________ inaccurate).

A

phonologically, phonetically

27
Q

_______ is the physical production and perception of speech sounds in any language.
_________ on the other hand is the interpretation of speech sounds and patterns in a specific language

A

phonetics, Phonology

28
Q

Productions lack articulatory __________ leading to distortion errors
Considered lower level ________ problem i.e. motoric basis.

A

precision, phonetic

29
Q

what is an Articulation Disorder: Due to Structural Anomaly and give examples

A

> Atypical physiological /anatomical development
Phonological /language rules are in place, piece of anatomy is missing
ex. Cleft Lip and Palate, VPI/VPD, hearing impairment

30
Q

What is the first step in deciding weather sound errors indicate an articulation of phonological problem

A

If the errors occur in patterns it’s phonological (sound rules), if the sound error occurs on one phoneme across all contexts it’s an artic problem (motor)

31
Q

True or false delayed phonological kids have intact cognitive-linguistic/ phonological / articulatory systems

A

True

32
Q

True or false Consistent Deviant kids have intact Cognitive-Linguistic /Internal representations of sounds

A

FALSE cognitive linguistic level is faulty

33
Q

Which SSD has an intact but unstable phonological system

A

Inconsistent deviant

34
Q

Which SSD has a deficit in Output fine-motor skills

A

Articulation disorder

35
Q

What is Differential diagnosis?

A

differentiating b/w sub-groups In clinically relevant or practical way

36
Q

True or false in phonological disorders sound production in isolation is mostly okay.

A

TRUE - it’s when sounds are put into contexts that errors occur (i think lol)

37
Q

What additional tasks could be performed if the child scores in grey area on inconsistency test to identify a child as having a consistent deviant phonological disorder?

A

Consistent deviant will do Poorly on Phonological awareness tasks:
> Assessing Rhyme/Alliteration
> Rule Derivation Task (computerized game-child has to find out hidden rules),
> Flexible item selection task (Pick two pictures that match).
> reverse recall tasks = impaired phonological working memory

38
Q

Why do consistent deviant phonological disorder kids have trouble with tasks involving Phonological awareness?

A

Because they have a deficit at the Cognitive linguistic level and it impairs their ability to abstract phonological rules

39
Q

Once a child displays atypical errors what test should you run to determine if they are consistent or inconsistent?

A

If a child shows ATYPICAL errors – your next step is to run an inconsistency test (DEAP)

 Below 40% inconsistent
• Consistent deviant phonological

40
Q

If a child recieves below ____ inconsistent it means they should be classified as Consistent deviant phonological

A

40%

41
Q

If a child recieves over 40% on the inconsistency test what are the two possible disorders they may be displaying

A

Inconsistent Phonological Disorder or Childhood Apraxia of Speech

42
Q

What are some ways we can differentiate between inconsistent and CAS?

A

In children with apraxia: oro motor difficulties are present, Spontaneous speech better than imitation (inconsistent better at imitation), articulatory groping present, have suprasegmental issues (none in inconsistent) such as Rhythm, stress or intonation issues

43
Q

From most to least common, list SSDs likely to be in your case load

A

Delayed phonological (57%), Consistent deviant (21%), Artic disorders(13%) and inconsistent deviant (9%)

44
Q

What are the 4 levels in the 4-Phase Speech Processing Framework
(Van der Merwe, 2009)

A
  1. Auditory-perceptual encoding
  2. Memory processes
  3. transcoding processes
  4. Neuromotor implementation processes
45
Q

processes that transform auditory input into phonemic, sublexical, and lexical representations is termed ________

A

Encoding

46
Q

Children with which SSD will Encode incoming information poorly= Fuzzy phonological representation for individual speech sounds

A

Phonological Delay

47
Q

Memory processes

include phonological planning and phonological memory involved in the process of…

A

process of phoneme selection & Sequencing meaning Target utterance is held in memory -> prosodic frame is constructed -> articulatory representations for the target segments are slotted into the frame in the correct sequence and finally Prosodic/segmental units are retrieved from memory

48
Q

At which level of the speech chain is the deficit in children with Delayed Phonological

A

Auditory-Perceptual Encoding

49
Q

At which level of the speech chain is the deficit in children with Consistent Deviant Speech Disorder

A

Cognitive-linguistic rule extraction

Phonological working memory

50
Q

At which level of the speech chain is the deficit in children with Inconsistent Deviant Speech Disorder

A

Phonological plan/template level

51
Q

At which level of the speech chain is the deficit in children with CAS & Articulation Disorders

A

Transcoding (motor/phonetic plan/program)

52
Q

At which level of the speech chain is the deficit in children with Dysarthria / Articulation issues
