1
Q

how can ideas become sounds and then back to ideas

A

consistent well defined patterns

2
Q

What are morphemes (free vs bound)

A

smallest language unit that carries meaning
free- can stand alone ‘cat’
bound - must be attached to another morpheme -s, -ed

3
Q

What are phonemes

A

smallest unit of sound that can serve to distinguish words

4
Q

what are vocal folds?

A

two flaps of muscular tissue within the larynx

5
Q

What is voiceing? how is it produced

A

a buzzing sort of vibration produced by rapid opening and closing of vocal folds
- sounds can be voiced or voiceless

6
Q

What is manner of production?

A

How the airflow is restricted (allows us to distinguish sounds)
- complete stop or continuous airflow?

7
Q

what is place of articulation

A

Where the airflow is restricted

- labiodental, alveolar

8
Q

labiodental sounds

A

front teeth close to bottom lip /f/ and /v/

9
Q

alveolar

A

tongue behind teeth /t/ and /d/

10
Q

what are the 3 production features we use to categorize speech sounds

A
  • manner of production
  • voicing
  • place of articulation
  • sounds that only differ by one sound similar while those differing by multiple features sound more distinct
11
Q

how many different phonemes

A

40

12
Q

misperceptions in speech are usually off by

A

one production feature

13
Q

normal speaking rate = ___ phonemes per second, ___ per minute

A

15, 180

14
Q

people can follow speech that is ____ words per minute.

A

250,

15
Q

define speech segmentation

A

slice stream of sound into appropriate segments

16
Q

What evidence proves the illusion of hearing spaces b/w words is in fact an illusion?

A
  • people hear pauses in the wrong place when they don’t understand what someones saying
  • When we physically measure speech stream there are no pauses
  • foreign languages sound uninterupted and fast because we don’t have the skills to segment
17
Q

What is coarticulation

A

We don’t produce phonemes one at a time, instead they overlap

18
Q

How do we use our knowledge about vocabulary when perceiving speech

A

when you hear the first syllable all words starting with that sound get activated

  • with the second syllable tthe cohort narrows
  • and so on till you find a match
19
Q

The importance of context was shown using the phonemic restoration effect. what is it, and how was it shown?

A

researchers modify tape-recorded sentences, take out a single syllable from one of the words and replace it with a burst of noise

  • participants generate the missing sound on their own because of the context and claim to have heard it along with the burst of noise
  • in addition they can’t tell where the noise appeared in the word
20
Q

How did Pollack and Pickett demonstrate the benefits of context? (sentence splicing)

A

Recorded conversations and then spliced out individual words and presented them to new subjects

  • they were only able to identify half without context
  • with context they were easy to understand
21
Q

define categorical perception

A

People are much better at distinguishing sounds across categories and are surprisingly insensitive to differences within a category
- beneficial because it allows you to hear differences that matter while ignoring variation within a category

22
Q

How is categorical perception demonstrated in the data?

A

Computer generates stimuli longer the /ba/ –> /pa/ continuum.
- we expect there to be a graded- membership pattern, however there is an abrupt shift at the phonemic boundary so that half the stimuli is identified as /pa/ and the other half at /ba/ with no fine degradation within either category

23
Q

what determines whether a plural is pronounced as /s/ or /z/

A

how the base noun ends

  • ends with voiced sound = /z/
  • ends with voiceless sound = /s/
24
Q

can these phoneme combination principles be observed for novel or made up cases ?

A

yes - wugs

- even in young children

25
Q

define referent

A

what a word refers to

- if you know a word’s referent you know what it means

26
Q

why does a words meaning involve more than it’s referent?

A
  • because some words don’t have referents (unicorn)

- some referents are temporary ( president)

27
Q

so what does it mean to know a word?

A

knowing the relevant concept

28
Q

define generativity

A

capacity to create an endless series of new combinations with a set of fundamental units

29
Q

what does it mean to know a language? is this knowledge conscious?

A

To know how to create new forms by combining morphemes and how to adjust phonemes based on their combinations
no people can’t explain why or how they do this

30
Q

why is semantic meaning not sufficient for determining if a sentence is gramatical?

A

some sentences have no meaning but are still gramatical

31
Q

what are phrase structure rules?

A

stipulations that list the elements that must appear in a phrase as well as the sequence for those elements

32
Q

what must a sentence consist of?

A

an NP and a VP

33
Q

what are prescriptive vs. descriptive rules

A

perscriptive: how language is suppose to be used according to grammer books. Proper language - defined by the most prestigious social group
descriptive: characterizing the language as it is used by fluent speakers/listeners
ex. phrase structure rules

34
Q

what study showed that phrase structure improves memory?

A

listeners memorize a string of words with either no structure or with function words included. Although function words were longer, this sentence was much easier to recall

35
Q

how does phrase structure help you understand a sentence

A

it indicates the relationships between the words

36
Q

what are linguistic universals? examples

A

principals applicable to all human languages

  • all languages have nouns and verbs and pronouns
  • in 98% subject preceeds verb
37
Q

what is the rationale for how children learn language so quickly

A
  • All children are born with a biological heritage that stipulates the broad outline of human language
  • children are born knowing the universal principals and it is just a matter of adjusting the parameters to fit their language community
38
Q

define parse? how do people parse sentences

A

= indentifying each words syntactic role

- happens as we go, which is more efficient but can lead to errors

39
Q

what is garden path. what does it show

A

sentences with temporary ambiguity are interpreted incorrectly and must be rejected to seak an alternate construction
- highlights the risk of interpreting a sentence as it arrives

40
Q

what is parsing guided by?

A

Minimal attachment: the listener preceeds through the sentence seeking the simplest phrase structure that will accomodate the words heard so far
Background knowledge: WHat is most likely to happen is the real world
-relience on function words
- tendency to interpret sentences as active
- context within the sentence or conversation and extralingual context
- intonation

41
Q

what causes garden path?

A
  • minimal attachment
  • tendency to interpret sentences as active (the initial noun is the doer)
  • relience on function words ( signal grammatical relationship) and background knowledge
42
Q

How were real world knowledge effects on parsing documented?

A

using eye-tracking it has been found that

  • when the initial noun phrase is an object that can’t perform the following action people realize the sentence will be passive
  • people tend to interpret an ambiguous word as it’s most common meaning (statistical strategy)
43
Q
what is extralingual context? 
provide example (apple)
A

physical and social settings in which you encounter sentences
‘ put the apple on the towel into the box’, if there are two apples to choose from on the towel will be interpreted as the specifier and not the destination

44
Q

what is prosody

A

rhythm and pitch of speech - rise and fall of speech sounds

  • reveals mood
  • can disambiguate sentences by directing listeners attention to the theme
45
Q

what are pragmatics?

A

how language is normally used

46
Q

what is Broca’s aphaisa

A
  • caused by damage to the left frontal lobe (broca’s area - speech prodcution)
  • produces nonfluent aphasia
  • speech is limited and effortful
47
Q

What is wernicke’s aphasia

A
  • caused by damage to wernicke’s area (left temporal lobe - language comprehension)
  • produces fluent aphasia
  • produces meaningless speech freely
  • sentences full of filler words
48
Q

can language loss in aphasias be specific?

A

yes, sometimes imparment is just to a particular procesing step

49
Q

at what age is a child able to converse

A

3 or 4

50
Q

what shows that children can learn language with adult communication that is totally non linguistic

A

children born deaf who aren’t taught sign will develop their own gestural language (home sign)
- thier invented language has the same formal structures and emergence patterns as ordinary language

51
Q

what does specfic language impairment tell us about specific neural mechanisms for language

A

these individuals have normal intellegence but are impaired in linguistic tasks showing that if specialized language mechanisms are distrupted other areas remain in tact

52
Q

What do over regularization errors tell us about how children learn language

A

it rules out the direct influence of imitations because adults never produce these forms

53
Q

is learning a language explicit instruction?

A

no studies have shown that parents rarely correct their childrens grammar/syntax. they are more concerned with content

54
Q

what experiment shows that babies/children are extremely sensitive to patterns and regularities

A

8 month old infant shown 2min recording of made up language in which certain syllables were statistically more likely to follow each-other (forming ‘words)
in test were suprised when the syllables were combined in novel ways - meaing they had learned the vocab of the made up language

55
Q

what is semantic bootsrapping

A

children rely on their knowledge of semanitc relationships to figure out syntax

56
Q

how can language effect decsions

A

patients are more likely to choose a treatment if told it is 50% succes rate rather than 50% failure rate

57
Q

what is linguistic relativity

A

the language you speak leads to certain modes of thought

58
Q

what evidence suggests language can impact perception

A

lanaguages with richer color vocab may percieve colors differently , making finer and more sharply defined distinctions

59
Q

how can language change how we remember and perceive spatial position

A
  • some languages emphasize absolute direction (independent of viewpoint - north/west)
  • others emphasize relative direction (relies on viewpoint - right or left)
  • others emphasize intrinsic direction (relative to an object)
60
Q

how can language change memory of events?

A

in english we emphasize active sentences while Japanese and Spanish omit the agent
- when remembering events they are less likely to remember who triggered the accident

61
Q

how should we think about these results according to Whorf’s original hypothesis?

A

language has a direct impact on congnition

  • categories in your language = categories in you thoughts
  • the effect is irreversible
  • there is no pervasive evidence for this theory
62
Q

What is a more modest interpretation of these results?

A

language influences cognition by shaping what we pay attention to, and these effects can be offset by other attention factors

63
Q

What differences do bilingual children show from monolingual children?

A
  • they learn both languages as quickly and as well as monolinguals but tend to have smaller vocab
  • they have better executive control ( avoid distractions, switching tasks, holding info in mind while doing something else)
  • language effects cognition
64
Q

During the course of this day, you might say about ______

These will be chosen from a vocabulary of approximately ______

A

20 000 words , 80 000 words

65
Q

What are the 3 levels of language?

A
  1. Conceptual level - category
  2. Word level (grammatical info) – that applys to the concept
  3. Sound level (phonological info)
66
Q

→ Speech oscillogram shows ______

→ Speech Spectogram shows _______

A

amplitude, Frequency kHz

67
Q

define VOT: Voice Onset Time

- VOT for /b/ and /p/

A

Time it takes between release of air and start of vocal fold vibration
-b/ less than 20 ms /p/ greater than 40 ms

68
Q

What does the McGurk effect tell us about how we perceive speech?

A
  • Understanding speech is multimodal.

- Visual information can dominate auditory 
information

69
Q

Define phonotactics

A

Rules for combining phonemes

70
Q

what does tip of the tongue effect demonstrate?

A

demonstrates the different stages of saying a word
- you have the lexical level, including grammatical information, and you might have the visual image as well, but you are missing some or all of the sound level

71
Q

what did TOT research, Dr. Karin Humphreys, McMaster find?

A

The longer you struggle to find a word the more likely they are to forget that word the next day

72
Q
  1. We easily add new _______

2. We don’t add new _______

A
  1. CONTENT words – Nouns, verbs, adjectives, adverbs
  2. FUNCTION words 
– Prepositions (of/with/to), determiners (the/a), pronouns (he/she/it), grammatical morphemes (ed/ing)
73
Q

what evidence is there against children learning and applying rules to learn language?

A

– Network models produce rule‐like behaviour without rules. We don’t yet know how the brain does it.

74
Q

Why are new words added to our vocabs?

A

due to changes in technology and other ways our experiences change, or as catch‐words in industry/marketing/entertainment
- also new meanings for old words

75
Q

what is the cohort model of words recognition?

A

Marslen‐Wilson model
– Activate everything compatible (the cohort), and whittle it down in real time as we hear the word.
– VERY fast process
• Not like you are stuck with the set of words you end up with – you can recover if there is an error

76
Q

how was the cohort model tested?

A

Lexical decision task (e.g. while hearing the word “captain”)
– Partway through hearing the word “captain” (at “cap…”), present “ship”
– Faster to respond to “ship” because “captain” is already activated 

• Crucial: also faster to “prisoner” because “captive” or “capture” is also activated by “cap…”
– If wait until the end of the word “captain”, no longer primed for “prisoner”, only “ship” 


77
Q

what is competence vs. performance

A

We may have an internalized system of rules that constitutes a basic linguistic competence, but this competence may not always be reflected in our actual use of the language (performance).

78
Q

surface vs deep structure

A

→Surface structure: syntactic, not necessarily meaning

→Deep structure: underlying meaning of a sentence

79
Q

what are Error Constraints

A

Speech errors may be disordered speech, but they are remarkable in their orderliness.
– Word errors follow word constraints

• grammatical category (nouns to nouns, verbs to verbs); outcomes are grammatically legal
– Phonological errors follow phonological constraints
• syllable position (onsets to onsets); outcomes are phonotactically legal

80
Q
  1. anticipation error
  2. perseveration error
  3. exchange error
A
  1. “lust and lime”
  2. “rust and rhyme”
  3. “lust and rhyme”
81
Q

What is the lexical bias for word errors?

A

– Error outcome consists of real words.

• Phonological errors are more likely to occur when the error outcomes are real words than when they are nonsense words.

82
Q

What is the feedback account of lexical bias?

A
  • Partially activated phonemes feed back to the connected words.
  • These then feed forward to other connected phonemes – a resonance of activation.
  • Nonwords have no word node to support the accumulation of activation, making them less likely.
83
Q

when comparing ability of Dani and americans to remember and percieve color, what happened

A

although Dani (Indonesian New Guinea) Only has two words for colour they have the same memory and perception as American subjects (( did have different results from brits though)

84
Q

what are function words

A

words that have little lexical meaning or have ambiguous meaning, but instead serve to express grammatical relationships with other words
