Title: Chapter 10: Language in Context


1
Chapter 10 Language in Context
2
Some Questions of Interest
  • How does language affect the way we think?
  • How does our social context influence our use of
    language?
  • How can we find out about language by studying
    the human brain?

3
Language Affects Cognition Perception, Memory
4
Linguistic Universals
  • Color naming
  • All languages use a set of 11 color names in
    hierarchical order
  • Black/white
  • Red
  • Yellow/green/blue
  • Brown
  • Purple/pink/orange/gray

5
Language on perception demo
6
Language Affects Memory
  • Washing clothes
  • Leading questions in eyewitness testimony

7
Linguistic Relativity
  • Sapir-Whorf hypothesis
  • Strong interpretation Thoughts and behavior are
    determined by language
  • More evidence against than for
  • Milder interpretationThoughts and behavior are
    influenced by language

8
Linguistic Relativity Studies
  • Bilinguals maintain that they think differently
    in different languages (Wierzbicka, 1985)
  • Differences in lexicons support lexical
    relativity when language differences lead to
    differing mental structures
  • But Eskimos dont really have words for snow

9
Grammatical Gender
  • Memory
  • Taught Spanish and German speakers object-name
    pairs (e.g., apple-Patrick)
  • remembered object-name pairs better when the
    gender of the proper name given to an object was
    consistent with the grammatical gender of the
    object
  • Perception
  • Masculine in German, feminine in Spanish
  • German hard, heavy, jagged, metal, serrated
  • Spanish golden, intricate, little, lovely, shiny

10
Bilingual Studies
  • Additive bilinguals
  • Learn a second language without loss to the
    native language
  • Subtractive bilinguals
  • Learn a second language that interferes with the
    native language
  • Simultaneous bilingual
  • Learn two languages from birth
  • Sequential bilinguals
  • First learn one language and then another

11
Factors Influencing Bilingualism Fluency
  • The earlier in life a second language is learned,
    the more fluent the speaker will become
  • Bahrick colleagues disagree
  • Vocabulary and fluency is acquired just as well
    in older participants but not fluency

12
Bilingual Studies
  • Research showing advantages
  • enhanced executive functions
  • delayed onset of dementia
  • acquire more expertise in their own language
  • sensitive to subtle aspects of language
  • perform better on tests of nonverbal intelligence
    that require recognition of verbal patterns

13
Bilingual Studies
  • Research showing disadvantages
  • have smaller vocabularies
  • access to lexical items in memory is slower

14
Pidgins and Creoles
  • Pidgins
  • Communication between two language groups
  • between immigrants and locals or missionaries and
    natives in order to be understood by each other
    without having to learn the language of the other
    group
  • Creoles
  • are complete languages
  • Does have native speakers
  • Has developed through expansion form and grammar
  • Is stable and autonomous in its norms

15
Dialects
  • A regional variety of a language distinguished by
    features such as vocabulary, syntax, and
    pronunciation

16
Spalking in Toonerisms
  • Chipping the flannel
  • Box in the Jack
  • Your model is renosed
  • shaking my tower
  • Mardon me, Padam
  • the cricking of the chirpets
  • my stickers were fingy
  • heat seaters

17
Slips of the Tongue
  • Errors can occur at any stage of speech
    production
  • Phoneme exchange
  • At the lead of spite
  • Go and shake a tower
  • Word-level error
  • I have to fill up my gas with car
  • Once I stop I cannot start
  • Your model is renosed

18
Figurative Uses of Language
  • Metaphor
  • Two nouns placed together to note similarities
  • Argument is war
  • Theories are buildings
  • Ideas are food
  • Similes introduce the words like or as into a
    comparison between items

19
Figurative Uses of Language
  • Metaphor
  • Argument is war
  • Theories are buildings
  • Ideas are food
  • Four key elements
  • Tenor
  • Vehicle
  • Ground
  • Tension

20
Mixed metaphors
  • A bird in hand is better than two burning in the
    bush
  • Up the creek without a canoe
  • Well burn that bridge before we get to it.
  • Strike while the iron is in the fire.

21
Pragmatics
  • Knowing what to say, how to say it, and when to
    say it or how to be around other people (Bowen,
    2001)
  • Study of discourse and conversational skills
  • Situational determinants of the use of language

22
Pragmatic Skills
  • Establish common ground
  • Introduce a topic in order for the listener to
    fully understand
  • Maintaining a topic
  • Or change topic appropriately
  • Or interrupt politely
  • Appropriate eye contact
  • Not too much staring
  • Not too much looking away

23
Speech Acts
  • Five basic categories
  • Representative conveys info
  • I like polar bears.
  • Directive is order or request that causes
    behavior
  • Turn on the air conditioner.
  • Commissive is a promise/agreement to do something
  • I will make the cookies.
  • Expressive conveys information about inner state
  • I enjoy spending time with you.
  • Declaration is a statement that brings about new
    situation
  • I am now a vegetarian.

24
Social context affects speech act choices
  • Bob is a junior executive for a fairly large
    corporation. He is on friendly terms with John,
    the company president, and they occasionally have
    lunch together. A few days earlier, they had both
    attended a company board meeting during which
    John had made a presentation. The presentation
    had not gone well and was obviously not well
    thought out. A few days later, Bob and John are
    alone and having lunch together when John says to
    Bob, What did you think of the presentation that
    I gave to the board the other morning?

25
Research on Speech Acts
  • Which of the following responses would you give?
  • Direct and true I really didnt think your
    presentation was very good.
  • Direct and false I really thought your
    presentation was very good.
  • Indirect evasive question Dont you think we
    should have our board meeting on some other day
    than Monday?
  • Evasive assertion I think we should have our
    board meeting on some day other than Monday.
  • Indirect irrelevant question Wasnt that latest
    stock market rally sure a surprise?
  • Irrelevant assertion The latest stock market
    rally was sure a surprise.

26
Indirect Speech
  • Direct speech
  • Open the window.
  • Indirect speech
  • Could you open the window?
  • It sure is hot in here.

27
Pinkers Theory of Indirect Speech
  • Indirect speech can serve three purposes
  • Plausible deniability
  • Relationship negotiation
  • Language as a digital medium of indirect as well
    as direct communication

28
Conversational Postulates
29
Gender Differences in Language
  • Girls tend to talk about one topic
  • Girls talk face to face
  • Women tend to overlap and finish each others
    sentences
  • Boys tease, tell jokes, notice things around the
    room, talk about finding games to play
  • Boys talk at angles, eyes straight ahead
  • Men perceive this as an interruption, intrusion,
    or lack of attention

30
Animal Language
31
Grey Parrots
  • Labels for more than 35 objects (e.g., paper,
    key, wood, cork, etc.)
  • Functional use of No
  • Phrases such as I want X, Wanna go Y, where X and
    Y are appropriate words
  • Labels for 7 colors
  • Can identify number of items up to 6
  • Alex can use vocabulary to identify proficiently,
    request, refuse, categorize, and quantify more
    than 100 different objects

32
Washoe
  • Washoe was able to use term more appropriately
    in different contexts
  • First use was more tickling
  • Transferred the sign dog to the sound of barking
    by an unseen dog
  • Washoe adopted an infant named Loulis
  • No humans signed in front of infant chimp
  • Loulis still managed to learn over 50 signs from
    other chimpanzees
  • No active teaching, rather Loulis just learned
    through observation among other signing chimps

33
Nim Chimpsky
  • Believed that apes only used signs to get rewards
    from trainers
  • Raised Nim in a human-like setting
  • Nim learned many words like dirty, sleep, bite,
    and angry
  • Nim did not learn to combine words to create new
    meaning on his own
  • After the experiments he continued to sign his
    most-used signs seemed to be drink, gum, banana,
    and more

34
Koko
  • Patterson raising gorilla named Koko since 1972
  • Has a greater vocabulary than Nim
  • Uses more words per utterances
  • Koko uses structure, is creative and spontaneous
    in her language
  • Koko has a vocabulary of over 1,000 signs, and
    understands even more spoken English
  • Koko invented her own new compound signs (e.g.,
    finger-bracelet for ring)

Neuropsychology of Language
36
(No Transcript)
37
Neuropsychology of Language
  • Brain and semantics
  • ventral temporal lobes, including middle and
    inferior temporal, anterior fusiform, and
    anterior parahippocampal gyri
  • the angular gyrus
  • the anterior aspect (pars orbitalis) of the
    inferior frontal gyrus
  • the dorsal prefrontal cortex
  • the posterior cingulate gyrus

38
Neuropsychology of Language
  • Brain and syntax
  • ERP called P600 occurs after hearing a sentence
    with syntactic violations
  • ERP called N400 occurs after hearing a sentence
    related to semantic violations

39
Neuropsychology of Language
  • Brain and sign language
  • The locations of lesions that would be expected
    to disrupt speech also disrupt signing
  • All right-handers with signing deficits show
    left-hemisphere lesions, as do most left-handers
  • Some left-handers with signing deficits show
    right-hemisphere lesions

40
Neuropsychology of Language
  • Aphasia
  • Impaired language function due to brain damage
  • Wernickes
  • Brocas
  • Global
  • Anomic

41
Normal vs. Wernickes Aphasia
42
Normal vs. Brocas Aphasia
43
Neuropsychology of Language Autism
  • Abnormal social, language, and cognition
    behaviors
  • Sex differences in brains
  • Extreme male brain
  • Executive dysfunction theory
  • Problem with frontal lobes
