Title: PSY 369: Psycholinguistics


1
PSY 369 Psycholinguistics
  • Review for Exam 3

2
Chapters and topics
  • 9 Conversation
  • 10, 11, 12 Language Acquisition
  • Early, Late, and Processes
  • 14 Language thought

3
Conversation
  • Conversation is a specialized form of social
    interaction, with rules and organization.
  • Herb Clark (1996)
  • Joint action
  • Autonomous actions vs. Participatory actions
  • Face-to-face conversation - the basic setting
  • Meaning and understanding
  • Establishing Common Ground
  • Common ground is necessary to coordinate
    speakers meaning with listeners understanding
  • Knowledge, beliefs and suppositions that the
    participants believe that they share
  • Identifying participants
  • Layers
  • Conversation is structured

4
Identifying participants
  • Conversation often takes place in situations that
    involve various types of participants and
    non-participants

5
Structure of a conversation
  • Conversations are purposive and unplanned
  • Typically you cant plan exactly what youre
    going to say because it depends on another
    participant
  • Conversations look planned only in retrospect
  • Conversations have a fairly stable structure
  • Opening the conversation
  • Identifying participants
  • Taking turns
  • Negotiating topics
  • Closing conversations

6
Taking turns
  • Typically conversations dont involve two (or
    more) people talking at the same time
  • Three implicit rules (Sacks et al, 1974)
  • Rule 1 Current speakers selects next speaker
  • Rule 2 Self-selection if rule 1 isnt used,
    then next speaker can select themselves
  • Rule 3 current speaker may continue (or not)
  • These principles are ordered in terms of priority
  • The first is the most important, and the last is
    the least important

7
Language Acquisition
  • Some of the major issues
  • Imitation vs Innateness
  • Learning words
  • General patterns and observations
  • Proposed Strategies
  • Fast mapping
  • Whole object
  • Mutual exclusivity
  • Learning Syntax
  • Learning Morphology
  • Commonalities across languages and cultures

8
Typical language development
  • 24 Months
  • Can name a number of objects common to his
    surroundings
  • Is able to use at least two prepositions
  • Combines words into a short sentence
  • Vocabulary of approximately 150-300 words
  • Volume and pitch of voice not yet well-controlled
  • 6 Months
  • Responds to his name
  • Responds to human voices without visual cues by
    turning his head and eyes
  • Responds appropriately to friendly and angry tones
  • 18 Months
  • Has vocabulary of approximately 5-20 words
  • Vocabulary made up chiefly of nouns
  • Some echolalia (repeating a word or phrase over
    and over)
  • Is able to follow simple commands
  • 12 Months
  • Uses one or more words with meaning (this may be
    a fragment of a word)
  • Understands simple instructions, especially if
    vocal or physical cues are given
  • Practices inflection
  • Is aware of the social value of speech

9
In the beginning
  • Prelinguistic communication
  • Mahler (mid 80s, in France)
  • 4 day old babies Russian vs French
  • Nonnutritive sucking method
  • DeCasper, et al (1994)
  • Had mothers read stories everyday to fetuses
    during 34-38 weeks of pregnancy
  • After 38th week, babies reacted differently (HR)
    to familiar story than new
  • Child-directed speech (motherese)
  • Early conversations

10
The early days phonology
  • Eimas et al, (1971)
  • Categorical perception in infants (1 month olds)

Sharp phoneme boundary
Young infants can distinguish different phonemes
11
Early speech production
  • The progression of cooing and babbling follows a
    universal pattern.
  • Babies, until around 6 months old, can produce
    sounds/phonemes that their parents cannot produce
    or distinguish
  • 6 - 8 weeks cooing
  • 4 - 6 months babbling
  • 6 - 7 months Reduplicated babbling
  • 8 - 9 months CVC clusters may appear
  • 10 or 11 months Variegated babbling dab gogotah
  • By 12 to 14 months some evidence of language
    specific phonological rules

12
Language Sponges
  • Learning words
  • Methods used to study this
  • Diary studies
  • Taped language samples (Roger Brown)
  • Large database CHILDES
  • About 3,000 new words per year, especially in the
    primary grades
  • As many as 8 new words per day
  • Production typically lags behind comprehension

13
Early speech production
  • Transition to speech
  • Early words
  • Common Phonological processes
  • Reduction
  • Delete sounds from words
  • Coalescence
  • Combine different syllables into one syllable
  • Assimilation
  • Change one sound into a similar sound within the
    word
  • Reduplication
  • One syllable from a multi-syllabic word is
    repeated

14
Early word learning
  • First words (Around 10-15 months)
  • Emergence of systematic, repeated productions of
    phonologically consistent forms
  • Idiomorphs - personalized words
  • Developed in systematic ways
  • Not simply imitation, rather are creative
  • Learned importance of consistency of names
  • Typically context bound (relevant to the
    immediate environment)
  • Important people, Objects that move, Objects that
    can be acted upon, Familiar actions
  • Nouns typically appear before verbs

15
Semantic Development
  • Applying the words to referents
  • Extension
  • Finding the appropriate limits of the meaning of
    words
  • Underextension
  • Applying a word too narrowly
  • Overextension
  • Applying a word too broadly

16
Extensions of meaning
  • One-word-per-referent heuristic
  • If a new word comes in for a referent that is
    already named, replace it
  • Exception to that was horse, but it only
    lasted a day here

17
Quines gavagai problem
  • The problem of reference
  • a word may refer to a number of referents (real
    world objects)
  • a single object or event has many objects, parts
    and features that can be referred to

Frog
Frog? Green? Ugly? Jumping?
18
Learning word meanings
  • Fast mapping
  • Using the context to guess the meaning of a word
  • All got the olive tray
  • Several weeks later still had some of the meaning

19
Constraints on Word Learning
  • Perhaps children are biased to entertain certain
    hypotheses about word meanings over others
  • Markman (1989)
  • Object-scope (whole object) constraint
  • Words refer to whole objects rather than to parts
    of objects
  • Taxonomic constraint
  • Words refer to categories of similar objects
  • Taxonomies rather than thematically related
    obejcts
  • Mutual exclusivity constraint
  • Each object has one label different words refer
    to separate, non-overlapping categories of
    objects
  • An object can have only one label

20
Language explosion continues
  • Proto-syntax (?)
  • Holophrases
  • Single-word utterances used to express more than
    the meaning usually attributed to that single
    word by adults

21
Language explosion continues
  • Syntax
  • Basic child grammar (Slobin, 1985)
  • Similarities across all languages
  • Mean length of utterance (MLU) in morphemes
  • Take 100 utterances and count the number of
    morphemes per utterance

22
Language explosion continues
  • Syntax
  • Roger Brown proposed 5 stages
  • Stage 1 Telegraphic speech (MLU 1.75 around
    24 months)
  • One and two word utterances
  • Debate learning semantic relations or syntactic
    (position rules)
  • Children in telegraphic speech stage are said to
    leave out the little words and inflections
  • e.g. Mummy shoe NOT Mummys shoe
  • Two cat NOT two cats
  • More than two words
  • Stages 2 through 5
  • Stage 2 (MLU 2.25) begin to modulate meaning
    using word order (syntax)
  • Later stages reflect generally more complex use
    of syntax (e.g., questions, negatives)

23
How do kids learn the syntax?
  • Innateness account
  • Pinker (1984, 1989)
  • Semantic bootstrapping

Child has innate knowledge of syntactic
categories and linking rules
Child learns the meanings of some content words
Child constructs some semantic representations
of simple sentences
Child makes guesses about syntactic structure
based on surface form and semantic meaning
24
How do kids learn the syntax?
  • It is in the stimulus accounts
  • Children do not need innate knowledge to learn
    grammar
  • Speech to children is not impoverished (Snow,
    1977)
  • Children learn grammar by mapping semantic roles
    (agent, action, patient) onto grammatical
    categories (subject, verb, object) (e.g. Bates,
    1979)

25
Language explosion continues
  • Morphology
  • Typically things inflections and prepositions
    start around MLU of 2.5 (usually in 2 yr olds)
  • Wug experiment (Berko-Gleason, 1958)

26
Language explosion continues
  • Morphology

This person knows how to rick. She did the same
thing yesterday.
Yesterday she ________.
Typically children say that she ricked.
27
Acquiring Morphology
  • Stages in the acquisition of irregular inflections

time
  • On the face of it, learning these morphological
    quirks follows a peculiar pattern
  • Early correct irregular forms are used
  • Middle incorrect regular forms are used
  • Late correct forms are used again
  • Why do we find this type of pattern?
  • Memory and rules

28
Memory Rules
  • The use of overregularized forms starts at around
    the same that that the child is beginning to
    apply the default -ed rule successfully
  • Early All forms-- whether regular or
    irregular-- are memorized
  • Middle The regular rule is learned, and in some
    cases overapplied
  • Late Irregulars are used based on memory,
    regulars use the rule (the idea is that if the
    word can provide its own past tense from memory,
    then the past tense rule is blocked)

29
Positive and negative evidence
  • What kind of feedback is available for learning?
  • Positive evidence Kids hear grammatical
    sentences
  • Negative evidence information that a given
    sentence is ungrammatical
  • Kids are not told which sentences are
    ungrammatical(no negative evidence)
  • Lets consider no negative evidence further

30
Negative evidence via feedback?
  • Kids resist instruction
  • Cazden (1972) McNeill (1966)
  • Do kids get implicit negative evidence?
  • Brown Hanlon (1970)
  • Adults didnt show a preference for Adams
    grammatical or ungrammatical sentences (either in
    terms of what they understood or what they
    expressed approval of)

31
Evidence for critical period for language
  • Lenneberg (1967) proposed that there is a
    critical period for human language
  • Feral Children
  • Children raised in the wild or with reduced
    exposure to human language
  • What is the effect of this lack of exposure on
    language acquisition?
  • Two classic cases
  • Victor, the Wild Boy of Aveyron
  • Genie

32
Effects of the Critical Period
  • Learning a language
  • Under c. 7 years perfect command of the language
    possible
  • Ages c. 8- c.15 Perfect command less possible
    progressively
  • Age 15- Imperfect command possible
  • Johnson and Newport (1989)

33
Second language acquisition
  • Contexts of childhood bilingualism
  • Simultaneous versus Sequential acquisition
  • Frequency of usage of both languages
  • Dominance of L1 vs. L2
  • Language attrition
  • Mode of acquisition
  • Native bilingualism - growing up in a two
    language environment
  • Immersion - schooling provided in a non-native
    language
  • Submersion - one learner surrounded by non-native
    speakers
  • Language dominance effects
  • Relative fluency of L1 and L2 may impact
    processing

34
Bilingual Representations
  • How do we represent linguistic information in a
    bilingual lexicon?

35
Interesting effects in bilinguals
  • Interference
  • Does knowing two languages lead to interference?
  • Code switching
  • When bilinguals substitute a word or phrase from
    one language with a phrase or word from another
    language, usually follows rule of switched
    language
  • Cognitive advantages
  • Problem solving, executive control, inhibition
  • Bialystok and colleagues

36
Does language affect thought?
  • Sapir-Whorf hypothesis
  • Linguistic determinism
  • Language determines thought.
  • Speakers of different languages see the world in
    different, incompatible ways, because their
    languages impose different conceptual structures
    on their experiences.
  • Whorf posited that cultural thinking differences
    were the direct result of differences in their
    languages
  • Linguistic relativity
  • Weak version(s) of the linguistic relativity
    hypothesis
  • Language influences thinking conditions how we
    think and perceive the world

37
Color Terms
  • Brown Lenneberg (1954) codability
  • Berlin and Kay (1969) Color hierarchy
  • Hieder (1972)
  • Dani tribe of New Guinea use only two color names
  • Kay Kempton, (1984)
  • Investigated English and Tarahumara (no separate
    terms for blue and green
  • Winawer, Boroditsky and others (2007)
  • English and Russian divide up blues differently

38
Counting Arithmetic
  • Miller Stigler (1987)
  • The greater regularity of number names in
    Chinese, Japanese and Korean as compared to
    English or French facilitates the learning of
    counting behavior beyond 10 in those languages.
  • Miura et al (1993)
  • Another advantage is earlier mastery of place
    value (understanding that in 23 there are 2
    tens and 3 ones)
  • Gordon (2004) Piraha tribe
  • Hoi (falling tone one), hoi (rising tone
    two), aibai ( many)
  • Matching tasks - show an array of objects, they
    have to put objects down to match the array

39
Conclusions
  • At this point it is apparent that the strong view
    of Whorfs hypothesis is not supported.
  • However, there is continued support for the
    weaker version(s) of the hypothesis
  • The data from areas of investigation concerning
    color naming, counting arithmetic, reasoning,
    visual memory, and other areas (e.g., social
    inference) indicate that the use of certain
    specific terms can influence how we think
