AOS and CAS Flashcards
(57 cards)
AOS is problems with ____________ and ________.
motor planning and programming
T or F: AOS often exists in its pure form
False
What are the 3 definitions of AOS:
1) Cognitive Processing
2) Neuroanatomic
3) Behavioural
Describe the cognitive processing view of AOS:
Intact Linguistic level –> Impaired Motor Planning and programming level –> Execution
________ defines sensorimotor goals aka what needs to happen in the future.
Motor Planning
_______ defines commands for different muscle groups, depending on the specific articulatory situation, accounts for muscle tone, direction and range of motion. AKA what each muscle needs to do.
Motor programming
According to the neuroanatomic view what are the 4 brain areas associated with AOS:
1) Broca’s Area
2) Left Insula: subcortica structure along the cortico-bulbar pathway
3) Arcuate Fasciculus
4) Basal Ganglia
Based on the behavioural view of AOS there are 7 behavioural characteristics:
1) Reduced ability to perform skilled learned (esp. voluntary) movements.
2) Effortful/ groping articulation
3) Difficulty initiating
4) Articulatory inconsistencies on repeated productions
5) Prosodic disturbances
6) Automatic speech may be preserved or better
7) Increased difficulties with increased complexity or at a faster speaking rate
In the behavioural definition of CAS there are 3 segmental and suprasegmental features:
1) _________ errors on consonants and vowels in repeated production so syllables or words.
2) Lengthened and distrupted _________ between sounds and syllables
3) _______ especially in realization of lexical or phrasal stress (supresegmental duration, rate, stress, F0)
4) _________, inconsistency and imprecision
1) Inconsistent errors
2) Lengthened and disrupted co-articulatory transitions
3) Inappropriate prosody
4) Vowel errors
The _____________ is a standardized test for AOS that looks at DDKs, word repetition, limb/oral apraxia, complexity (polysyllabic word naming), successful repetitions, sponaneous vs automatic speech.
Apraxia Battery for Adults
___________ is the impaired ability to perform actions of the mouth and tongue. It is present in ____% of AOS cases.
Oral (non-verbal) apraxia
80%
_________ is impaired ability to repeat previously well-established actions
Ideation apraxia
________ is impaired ability to imitate unfamiliar actions, also called motor apraxia or ideokinetic apraxia
Ideomotor apraxia
_______ is impaired ability to copy simple drawings or patterns
Constructional apraxia
______ is impaired ability to dress
Dressing apraxia
________ is impaired ability to make eye movements, also called ocular apraxia.
Oculomotor apraxia
T or F: In CAS not only will automatic/ spontaneous supersegmentals may be intact they will also be able to imitate suprasegmentals.
False - automatic/ spontaneous may be intact but they won’t be able to imitate.
Tasks such as “stick out your tongue”, “bite your lower lip”, “show how you would kiss” and “whistle” are used to detect _______.
Oral Apraxia - which is present in 80% of AOS cases.
What are two main questions during AOS and CAS assessment?
1) Where does speech break down? - length, automaticity
2) What is the underlying issue? -artic or timing
What are some speech and sound production tasks used to assess apraxia?
- Imitation, spontaneous and repeated speech
- sounds, single syllables, multi-syllables, phrases, sentences
- Suprasegmentals (rate, pitch, volume, intonation)
During speech production consider __________ inventory not just error inventory.
phonetic
9 things to consider during speech production:
1) Phonetic/ error inventory
2) Consistency in repetition
3) Rich/ reduced sound/syllable repertoire
4) Groping
5) Organicity of imitated and spontaneous sounds
6) Typicality of errors
7) Omissions or substitutions
8) Disrupted sequencing
9) Stimuability
T or F: Spontaneous speech in apraxia is more motorically/ hetero-organic than speech on imitation.
True
T or F: “Go” is homo-organic (simple) and “open” is hetero-organically complex.
True
