Lecture 8: Language Flashcards
What are Hockett’s universal characteristics of language?
→ semanticity → arbitrariness → flexibilty and naming → duality of patterning → productivity (generativity) → displacement
What is semanticity in Hockett’s universal characteristics of language?
- language conveys meaning
What is arbitrariness in Hockett’s universal characteristics of language?
- signal doesn’t resemble what it represents
- no inherent connection between the units used in a language and their meanings
→ onomatopoeia excepted
What is flexibility and naming in Hockett’s universal characteristics of language?
- referents have labels and they can be changed
What is duality of patterning in Hockett’s universal characteristics of language?
- signal can be broken down into smaller units
What is productivity/generativity in Hockett’s universal characteristics of language?
- create infinite number of new meaningful utterances from a finite number of meaningful signals
What is displacement in Hockett’s universal characteristics of language?
- can communicate about things that aren’t present
What are Miller’s Five Levels of Language Analysis?
→ phonology → semantics → syntax → conceptual → belief
What is a phoneme?
- the smallest unit of sound that makes a difference to meaning
- can be consonants or vowels
What are the distinctive features of phonemes?
- voicing
- place of articulation
- manner of articulation
What is phonological voicing?
- when vocal cords vibrate when saying a phoneme it is voiced
- when vocal cords don’t vibrate when saying a phoneme it is unvoiced
- when vocal cords start to vibrate it is called voice onset time (VOT)
What is place of articulation?
- where the flow of air is altered to make a speech sound
What are the features of manner of articulation?
→ stops: blocking and releasing air, /p/
→ fricative: air is forced through a narrow passage, /f/
→ nasals: air is passed through the nasal cavity, /m/
What is the lack of invariance problem?
- phonemes are different depending on context they’re in
- phonemes are always coarticulated, i.e. more than one at the same time
- accent, speed, facial expression, physical differences, carefulness all affect speech stimulus
What is categorical perception?
- all sounds falling within a set of boundaries are perceived as the same, despite physical differences
→ /ba/ and /pa/ differ only in VOT
What is the segmentation problem?
- we hear clearly separated words, but there aren’t any clear breaks between words in the acoustic signal
What is the McGurk effect?
- shows how we use vision to help us hear
- delayed video can change /ga/ to /da/
What is a morpheme?
- smallest meaningful unit in language
What is a free morpheme?
- has its own meaning
What is a bound morpheme?
- only contributes to meaning but isn’t a word in itself
→ -ly for adverbs, -s for plurals
What is a polysemic word?
- word that has multiple meanings
→ dominant meanings is related to frequency of usage
How did Warren show the phonemic restoration effect?
- sentences present with a target word that is missing a letter and covered with a cough
→ most participants report that they didn’t notice anything missing - shows context can effect our perception of language, not just comprehension
What was Swinney’s lexical priming study?
- Swinney’s research measured response time to different words with either similar or different meanings.
- using ambiguous words as stimuli show that context exerts its influence after all meanings of the word have been briefly accessed.
What is syntax?
- concerns the structure of language
→ set of rules we use in language
→ can’t just combine words randomly - encompasses tacit rules of a grammar
What are grammars?
- set of implicit syntactic rules that make a language system regular and productive
What is prescriptive grammar?
- describes what you ought to use language “correctly”
What is descriptive grammar?
- describes language users’ tacit knowledge of the rules of language
What was Chomsky’s work on syntax?
- realized that sentences are composed of phrases rather than isolated words
- created phrase structure rules/rewrite rules
What are phrase structure rules/rewrite rules?
- formal rules for describing tacit knowledge people have for creating sentences out of groups of words
→ cannot account for sentences that have different structures but same underlying meaning
→ cannot account for ambiguous sentences
What is surface structure?
- actual phrases in the sentence
What is deep structure?
- hypothetical word string that accurately reflects the relationship between sentence elements
What is Fillmore’s case grammar?
- semantic analysis of sentences involves figuring out what semantic role is being played by each word or concept in the sentence and computing the sentence meaning based on those semantic roles
- agent (subject doing the action), patient (acted upon), location
- formed from syntactic structure, correspondence rules, and conceptual structure
What is parsing?
- dividing sentence into phrases and groups
