Q

n vs n - what kind of evidence supports each position

A

Evidence of innateness – Lenneberg 1967 -[defined characteristics of biological system]
1. behavior is not the result of a conscious decision
2. not triggered by external events
3. direct teaching has little effecti on language acquisition
4. there is a set of milestones – even if deaf and stuff
5. there is a critical period for acquisition
learners go beyond input
pidgins and creoles – kids introducing own structure for language
kids who say things they haven’t heard before, going beyond the input

Evidence for experience
critical period
you learn your own language
once need to speak goes away can actually lose knowledge/ability to speak
once you learn one by the end of the critical period will be able to learn more

Q

poverty of the stimulus

A

poverty of the stimulus – kids hear few sentence tokens than they know and understand
can’t just be imitating or memorizing
Even as adults we can make up sentences we haven’t heard before

Q

definition of a word

A

combination of sound and meaning, arbitrary pairing of sound and meaning that can be used to refer

32
Q

phonological processes that lead to systematic pronunciation errors, rule ordering

A 
consonant cluster reduction [deletion of a consonant in cluster]
substitution [replacing] 
 harmony [match to another part of word]
reduplication [repeating]
final consonant deletion
weak syllable deletion
voicing/devoicing
33
Q

production vs comprehension

A

able to understand before able to actually produce sounds

34
Q

phonological and semantic properties of early words

A

easy sounds, more nouns than verbs

35
Q

overextensions/underextensions

A

overextension - ‘goggie’ can mean any animal, underextension, ‘baba’ - may mean their bottle and only their bottle

36
Q

Quine’s problem

A

no 1:1 world/word mapping - the mapping between words and the world is ambiguous

37
Q

word-to-world mapping

A

applying words to things in the worlds

38
Q

fast mapping

A

children can form hypotheses about the meaning of a new word after only one exposure - carey & bartlett [1978]

39
Q

assumptions/constraints/cues/tools that guide word learning

A

whole object assumption, taxonomic assumption, mutual exclusivity

40
Q

Whole Object Assumptions

A

a novel label refers to an entire object, not to a properrty or a part of the object

41
Q

Taxonomic Assumption [superordinate, basic, and subordinate-level categories]

A

labels refer to things of the same kind, specifically, to things of the same basic level kind
superordinate - animal
basic - rabbit, dog, cat
subordinate - golden retriever, collie, poodle

42
Q

Mutual Exclusivity

A

different words refer to different [categories of] things

allows us to categorize objects, override the whole-object assumption

43
Q

language-specific vs domain general processes or constraints

A

are these processes specific to language or applied to all human? learning

44
Q

social cues to word meaning

A

pointing at stuff, only talk about things that are there, eyegaze, gestures

45
Q

nouns vs verbs

A

nouns name physical items, verbs are more ambiguous, concept of imaging

46
Q

syntactic bootstrapping

A

children can use cues from the linguistic [syntactic] context in which a new word is used to help them figure out its meaning

47
Q

Naigles 1990 study - syntactic bootstrapping

A

-2yo [who are not yet producing very many verbs!) can use cues from syntax to figure out which of two simulationeous events is being labeled by a novel verb
transitive frame = causative event
intransitive frame = noncausative event
-preferential looking task
-kids familiarized to two simulationeous events, - causative and continuous event
the duck is gorping the bunny! vs the duck and the bunny are gorping! - kids heard one of these when in realtion to picutre
after familiarized, shown two videos, have to find gorping and what they think it means
seem to find the sentence that matched to their sentence

48
Q

timeline of milestones in phonological and lexical development

A

look at paper

49
Q

experimental techniques - old diary studies

A

description and example

50
Q

new diary studies

A

recording everything they say

51
Q

corpus mining

A

trying to figure out what words kids know?

52
Q

habituation

A

exposed to a stimulus until they become habituated to it, see this habituation 4 different ways

53
Q

heart-rate monitoring

A

watching heart rate, faster for new, slower for habituated

54
Q

high-amplitude/non-nutritive sucking

A

measuring sucking rate, faster when interested in stimulus

55
Q

conditioned head-turn

A

conditioned to certain sound lighting up box

56
Q

head-turn preference paradigm

A

while child is looking at center, plays speakers and lights, english and russian playing from speaker, experiment will turn on one light and speaker then recenter him then play the other, and will keep doing until kid realizes which english comes from, next the kid gets to pick which they hear, head turn preference is which the kid turns to more often and how long they hear it

57
Q

preferential looking

A

see which they look at most, this is the one they are not habituated to

58
Q

object manipulation

A

holding up objects and asking questions

59
Q

human subjects paradigm

A

yeah i dont know

60
Q

Gleitman & Newport [1995]

A
  1. general issue being addressed and why it matters 2. methodology used 3. what they found and what the implications of that finding are - concepts not numbers
61
Q

Kisilevsky et al. [2003]

A

Kisilevsky et all 2003
Q: while in utero, can foetuses distinguish theirmother’s voice from the voice of a different female?
Methods: 2 min recording, spliced with silence 2 min before and 2 min after, 30 kids heard their own mother’s voice and 30 other woman’s voice, placed speaker 10cm above abdomen played the voices
measures to tell how kid can tell if recognize voice or noticeable
fetal body movement – didnt find really correlation
fetal heart rate – found some, gave silence at first to make sure they all started with the same heart rate
children = post foetuses

62
Q

Eimas, Siqueland, Jusczyk & Vigorito [1971]

A

looking at morpheme boundaries and how kids perceive them, habituation study with nonnutritive sucking, recognized stimulus as separate phoneme, but within VOT did not recognize stimulus as different, kids can distinguish voiced from voiceless stop consonants even at such a young age, and additionally they are capable of perceiving stops with VOT within the same phonemic range as belonging to the same category, is evidence that humans are wired on some level to acquire this distinction, strong evidence to innateness theories.

63
Q

Werker & Tees [1984]

A

me and delana - sets out timeline of language development, shows that children can distinguish contrasts that dont appear in their language, head turn paradigm, testing thompson contrast, then testing hindi and thompson and english contrast, adults can tell difference in own language, children can usually tell in both, between 8-12 lose ability to distinguish sounds not heard/contrasted in this language, may help them focus on a particular language

64
Q

Maye [2003]

A

commentary of werker and tees, helped elucidate a timeline of language development, still had a lot of questions, especially about second language development

65
Q

Saffran, Aslin & Newport [1996]

A

strings of syllables within random syllables, dishabituation studies with head turn preference, transitional probability, where the syllable boundary most likely is depending on language

66
Q

Aslin, Saffran & Newport [1998]

A

different made up syllables with real words interspersed, habituation study with head turn preference, hypothesis was that they would be more attentive to the part words than the words in their language, hypothesis was confirmed, provides evidence that one of the methods used by infants to segment speech is conditional probability.

67
Q

Bergelson & Swingley [2012]

A

since many kids dont say their first word until about a year of age, it is believed that kids dont understand words until that age either, helps set a timeline for infant language development, [conditioned head turn/head-turn preference paradigm?] ‘language-guided looking’, or ‘looking-while-listening’, infants were shown a number of pictures while their parents said the name of one/sentence, majority of the kids got most of the words, at 6-9 months, infants have already begun to link words with their referants over a range of food and body-part terms, were better at extremely stripped down context could also understand related alternatives, and have some idea of how language generally works.

68
Q

Waxman & Markow [1995]

A

linking of noun categories; hypo - 12 to 13 month old infants are capable of linking words to meaning and they expect that a new word applied to an object will refer to that object, familiarization phase of objects, kids familiarized quicker when its part of a category, understand categories, especially at superordinate level, categorization behavior is not evident in unrelated groups of words, in higher vocab group the novel word and novel adj helped them recognize categories at superordinate level, in low vocab group neither helped , 12 month olds do not distinguish between nouns and adjectives, link between infants vocabulary and their ability to connect words with object categories, start to be able to apply words to larger category

69
Q

Gillette, Gleitman, Gleitman & Lederer [1999]

A

testing adults on vocabulary learning, showed silent videos with beep, students were supposed to identify what word was, did better when had context, nouns easier because of imageability
