- 14 Language thought
3Conversation
- 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
4Identifying participants
- Conversation often takes place in situations that
involve various types of participants and
non-participants
5Structure 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
6Taking 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
7Language 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
8Typical 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
9In the beginning
- Prelinguistic communication
- Mahler (mid 80s, in France)
- 4 day old babies Russian vs French
- Nonnutritive sucking method
- 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)
10The early days phonology
- Eimas et al, (1971)
- Categorical perception in infants (1 month olds)
Sharp phoneme boundary
Young infants can distinguish different phonemes
11Early 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
12Language Sponges
- 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
13Early speech production
- 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
14Early 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
15Semantic 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
16Extensions 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
17Quines 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?
18Learning 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
19Constraints on Word Learning
- Perhaps children are biased to entertain certain
hypotheses about word meanings over others
- 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
20Language explosion continues
- Proto-syntax (?)
- Holophrases
- Single-word utterances used to express more than
the meaning usually attributed to that single
word by adults
21Language 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
22Language 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)
23How 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
24How 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)
25Language explosion continues
- Morphology
- Typically things inflections and prepositions
start around MLU of 2.5 (usually in 2 yr olds) - Wug experiment (Berko-Gleason, 1958)
26Language explosion continues
This person knows how to rick. She did the same
thing yesterday.
Yesterday she ________.
Typically children say that she ricked.
27Acquiring 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
28Memory 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)
29Positive 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
30Negative 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)
31Evidence 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
32Effects 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)
33Second 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
34Bilingual Representations
- How do we represent linguistic information in a
bilingual lexicon?
35Interesting 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
36Does 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
37Color 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
38Counting 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
39Conclusions
- 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
