L8: Language Flashcards
What is a language?
A system of arbitrary symbols and rules used to manipulate them
What kind of errors does the Spreading Activation Model cause in speech? 3 types
- Anticipatory errors
- Sun is in the sky -> Sky is in the sun - Perseveratory errors
- Beef noodle -> Beef Needle - Exchange errors
- I need to buy a new watch -> I need to buy a new botch
Are languages rule-based?
Yes, its system of rules forms a grammar or syntax.
What is preformulation?
The cognitive processes that occur before the actual articulation of speech sounds - preparation and planning of linguistic units, such as words. The production by speakers of phrases used frequently before; to reduce the demands of speech production.
How do we simplify speech production? 3 things
- Preformulation
- Underspecification
- Syntactic Priming
What is underspecification?
Certain aspects of meaning or structure in a linguistic expression are left unspecified.
What is syntactic priming?
Exposure to a particular syntactic structure in one context influences the production of similar syntactic structures in subsequent contexts. The tendency for the sentences produced by speakers to have the same syntactic structure as sentences they have heard or read shortly beforehand.
What are the 4 levels of spreading activation model?
- Semantic -> abstract representation of ideas
- Syntactic -> Outline, like grammar
- Morphological -> Structure of words using morphemes
- Phonological -> Pronunciation
What causes errors in the spreading activation model?
Because there is spreading activation, numerous nodes are all activated at the same time. If an incorrect item is activated more strongly than the correct item, it may get selected instead.
What is the lexical bias effect?
Proves that speech errors are not random, and errors generally form words rather than non words.
What is spoonerism?
Initial sounds or syllables of two words are swapped to create new words or phrases. ie. Deep cot -> Keep dot
Why do good speakers make more anticipatory errors?
Good speakers plan ahead more than novice speakers, so what they are planning to say gets more highly activated than what they are supposed to say.
What is aphasia?
Language problems caused by detectable brain damage.
What are the steps taken in spoken word recognition?
- Decoding speech involves breaking continuous speech into discrete phonemes.
- Then you have to identify words.
- Then you need to extract the meaning of the word for comprehension.
What is the TRACE model?
Operates on the principle of interactive activation and consists of three levels: feature, phoneme, and word.
How does the TRACE model work?
At the feature level, distinctive acoustic features of speech sounds are represented. These features activate phoneme units at the phoneme level, which in turn activates word units at the word level.
Evidence that speech perception is multimodal
People recognise auditory words more slowly when they are spelling-to-sound consistent (ie. kiss) vs spelling-to-sound inconsistent (ie. pint). This suggests that orthographic codes are also activated during spoken word recognition. McGurk effect also shows that what we “hear” involves an integration of visual (expression, movement of lips) and auditory information.
What is pure word deafness?
Severely impaired speech perception, but intact speech production, reading, writing and perception of non-speech sounds.
What does eye-tracking show? 3 things
Eyes don’t move smoothly. Readers spend more time fixating on content words, but less on function words. Readers also tend to skip short, predictable and common words.
How do we comprehend sentences? 2 ways
- Parsing
- Analysis of Meaning
What is parsing?
Analysing the grammatical structure of a sentence. Involves breaking the sentence down, and figuring out what the subject, verb and object is. Based on a language’s grammar
