Q

Q

Traits of Broca’s aphasia

A

Struggle to produce speech
* Halted speech
* Simple sentences
* Speaks in only nouns and verbs
* Drops words from sentences

Q

Neologisms paraphasia in Wernicke’s aphasia

A

Invented words (that do not convey meaning in aphasia)

e.g. kiuwerold

Q

Traits of conduction aphasia

A
  • Can read, write, and speak
  • Can usually understand spoken messages
  • Word-finding difficulty
  • Unable to repeat words or sentences (message cannot be sent to production area after perception)

Q

Brain lateralization

A

Language is often considered left lateralized, but :
Broad aspects ((non-literal language skills) of language are supported by the right hemisphere
* Prosody and pitch to convey intonation
* Mood, attitude, gestural communication

19
Q

Traits resulting from right-hemisphere lesion

A
  • Problems understanding the emotion of a phrase
  • Problems understanding sarcastic speech
20
Q

Are we pre-equipped with language capabilities according to the nuturist view ?

A

No. Language is acquired through the same mechanisms as skill learning (behaviorist view)

21
Q

Are we pre-equipped with language capabilities according to the naturist view ?

A

Yes. We are born with the innate capacity to learn language

22
Q

Nuturist or behaviourist view

A

Language acquisition is skill or associative learning
* Explicit training of language
* Trial and error reinforcement as well as modelling other people shapes language

23
Q

The innateness hypothesis

A

Grammar, syntactic structure, is separate from semantic meaning and cognition; and it is innate

24
Q

Chomsky and Naturist views

A

Language is innate because :
* Language is not stimulus dependent or determined by reinforcement
* Language is way too complex, can be learned without punishment and acquired rapidly
* We can understand and speak what we have not heard before

25
Language Acquisition Device (LAD)
Entity that supports language
26
Universal Grammar
A part of the LAD that includes rules for all languages * Children only need to learn language-specific aspects to put “on top” of Universal Grammar
27
Convergence : support for the naturist view
Children are exposed to different learning situations, yet converge on the same grammar E.g. All children follow the Structure-dependent hypothesis when forming double-auxiliary questions
28
Uniformity : support for the naturist view
There is uniformity of developmental milestones of learning language across children
29
Poverty of stimulus argument
The linguistic environment of a child is not sufficient for a child to learn a language via reinforcement, rules or imitation alone * A child doesn’t hear enough language to acquire all language * This means they won’t have enough opportunities to learn from mistakes * This means there must be something innate about language
30
Critic of the poverty of the stimulus argument
The environment is not so impoverished * A child hears around 6,000 to 21,000 words per day! - Evidence that rules are not all innate * Adult reformulations of children’s speech target the structure but not meaning : as rules need to be refined, maybe the rules are not so innate in the first place
31
Phonological ambiguity and top-down knowledge
You use context and internal knowledge of speech sounds to “hear’ E.g. reading a word primes you to hear it (McGurk effect)
32
Lexical ambiguity
A single word form can refer to more than one different concept e.g. BARK ( > 80% of English words have more than one dictionary entry) Basis of Puns
33
Cross-modal priming task results - for analyzing if homophones activate both meanings in the brain Lexical decision task Participants heard the word bug in no context or biasing context to hear the insect meaning
With short delay : Bias and no context→ both meanings were active * Bug primes spy (context inappropriate) and ant (context related) With long delay : Only context biased meaning active * Bug primes only ant (context related) **Conclusion** : Both meanings are initially retrieved, but contextually inappropriate meaning is quickly discarded
34
Sentence parsing
* dividing a sentence into words * identifying them as nouns, articles, verbs
35
Syntactic mbiguity can come because ..
We hear sentences incrementally and there is often more than one way to parse a sentence (words can be nouns and verbs)
36
Garden path sentence
- Sentences with multiple syntax structures - Interpreting a word one way leads you awry
37
Syntax First theory of sentence parsing
- We use grammatical rules to interpret a sentence as we hear or read it (one direction) - Local or specific * You may get to the end and “oops” wrong meaning, so must go back *The horse raced past the barn fell*
38
Constraint based model of sentence parsing
- We use non-grammatical information to help interpret sentences and resolve any ambiguity - Global or holistic We use more than grammar to parse sentences : * Non-grammatical information can be used * Semantic and thematic context * Expectation * Frequency
39
Linguistic Relativity
Language and thought are interconnected
40
Linguistic Universalists
Language and thought are independent
41
Sapir Whorf Hypothesis
Language changes how we think and perceive * People who speak different languages think differently - Whorf believed Inuit people could perceive snow differently due to vast vocabulary
42
Colors across languages study
Russian language discriminates between lighter (“goluboy”) and darker (“siniy) blues, not English * English and Russian speakers performed a color discrimination task with blue colors * Task with no memory or language demands * Russian speakers were faster to respond for colors that fell into different than from the same blue category * English speakers showed no effect - suggests language impacts perception
43
Color across languages : inconsistent findings
English Language speakers: 11 words for color * Dani tribe in Indonesia: 2 words for color * Test 1: Named color patches: two groups performed this differently * Test 2: Match /categorize learned color patches, no group difference * Suggests accessing color category without language labels does not change across language Although they identified the colors differently, they seemed to match a remembered color patch to the right one equally well.
