Articulation and phonology - assessment and diagnosis Flashcards
What are the minimum requirements of a speech assessment?
- Single words (standardised ax)
- Spontaneous speech sample
- Consistency assessment
+ OPE and stimulability testing if required
What could you use to obtain a spontaneous speech sample? (4)
- Conversation
- Picture description
- Re-telling a story
- Role play
Key diagnostic information from speech assessment
- What they attempted to produce
- What they actually produced
- What was produced correctly
- What was produced incorrectly
- Nature of incorrect pronunciation
- Extent (% occurrence) of phonological processes/other errors
What is independent analysis vs relationship analysis of speech data?
Independent = looking at child’s unique system without reference to target/adult phonology - inventories
Relational = looking at child’s system relative to ideal target/adult phonology - percentages
Steps of independent analysis
- What is present - consonant inventory, vowel inventory, syllable-word shapes inventory, syllable-stress patterns inventory - match these for child’s age
- What is not present - inventory constraints (absent sounds), positional constraints (WI vs WM vs WF), sequential/phonotactic constraints (C/V combinations not used)
- Stimulability - for sounds that aren’t present try to elicit in isolation/syllables/words providing verbal/visual/tactile/auditory cues
How can stimulability to used to differentially diagnose?
Differential diagnosis of articulation (phonetic) and phonological disorder relies on whether an accurate production of the speech sounds in error can be elicited - if a speech sound is not stimulable, it is an articulation disorder
What is relational analysis?
Using single words and connected speech to determine:
- Percentage consonants correct (PCC)
- Percentage phonemes correct (PPC)
- Percentage vowels correct (PVC)
- Phonological processes analysis
How to measure severity (3)
- Effect of disorder on intelligibility
- Degree of concern caused for child/caregiver/teacher
- Consequences of disorder (eg. academic, social)
Prognosis for ‘functional’ phonological delay/disorder
Positive prognosis
What are the components of the DEAP assessment?
5 minute diagnostic screener - gives direction to assessment in other areas
1. Articulation
2. Phonology
3. Oro-motor ability
4. Inconsistency
How to cue if a child doesn’t know the name of a picture? (hierarchy 5)
- What’s this?
- Semantic cue
- Phonemic cue (eg. starts with)
- Forced choice
- Tell me/say ‘word’
How to test for a co-occurring language impairment? (4)
- Receptive vocab - PPVT-4
- Receptive grammar - CELF P3/5
- Pragmatics
- Phonological awareness - CTOPP-2
