Word Comprehension Flashcards
For word comprehension we go from speech -> _________ -> _________ -> _________
auditory phonological analysis -> phonological input lexicon -> semantic system
Describe Auditory phonological analysis
- begins with the sound wave and contains information such as gender of speaker, emotional state, accent, etc.
- “phoneme recognizers”
Describe the phonological input lexicon
- a store of all the sound patterns of the words we know
- allows you to recognize an item as a word in your language
T or F: you need the semantic system to recognize a word
FALSE only auditory phonological analysis and the phonological input lexicon
What are the three routes that repetition can be carried out?
- Bypass route: for the repetition of non words or unfamiliar words. Involves the acoustic to phonological conversion
- For words: pathway with semantic system
- Phonological input lexicon For words, pathway that bypasses semantic system (repetition but not understanding)
Describe pure word deafness
- impairment in auditory/phonological analysis
- impaired speech perception
- cannot repeat heard words
- can understand loudness, tone of voice, accent
- can recognize non speech sounds
- normal audiometry, production, reading and writing
Describe word meaning deafness
- disrupted connection between auditory input lexicon and semantics
- rare
- diff understanding speech
- spontaneous speech intact
- repetition, writing and reading intact, so can comprehend this way
Describe deep dysphasia
- impaired access to semantics from auditory input lexicon & impaired non-lexical bypass route
- auditory analogue to deep dyslexia
- many semantic errors in repetition
- semantic errors in writing to dictation
- poor with grammatical function words
- concrete > abstract
- unable to repeat new or nonword
Linguistic factors that affect lexical tasks
- word frequency
- grammatical category
- semantic category
- lexicality
- regularity
- age of acquisition
- imageability
- operativity
- length
- familiarity
How do we assess semantics?
-word picture matching
How do we assess the phonological output lexicon
-word fluency, naming test, repetition of words, reading aloud
How do we assess speech?
-OME
How do we assess the auditory phonological analysis
minimal pairs discrimination
How do we assess the phonological input lexicon
lexical decision task
