9: Language and Thinking Flashcards
What is language?
Language: a system of symbols (and rules for combining them) which can generate an infinite number of possible messages and meanings
What is Psycholinguistics?
Psycholinguistics: The scientific study of the psychological aspects of language.
- includes how people understand, produce, use and learn language
Why is it important to learn about language in a psychology class?
- Much of human cognition involve language
- e.g. thinking, reasoning, problem solving
- cognition/consciousness may depend on it
- inner voice (self-talking)
- Humans are social creatures
- language allows us to share thoughts, feelings, goals, intentions, etc.
- Language is universal
- all cultures, no matter how remote, have language
What is the adaptive function of language in human evolution?
- Humans formed larger & larger social groups throughout evolutionary history
- bigger groups helped us survive & reproduce
- also posed problems:
- different sets of knowledge, customs
- division of labor, cooperation
- teaching
- Language was an adaptation to these new demands!
Define and briefly describe the 5 properties of any language.
1. Symbolic
- Arbitrary symbols represent specific objects, actions
- i.e. words/sounds/signs don’t usually look or sound like the represented object
- e.g. “Dog”
2. Structured
- Rules for meanings, sound/word/phrase combinations
- ball boy girl green the the the to kicked
3. Conveys Meaning
- once people know symbols & rules, able to communicate ideas, thoughts
4. Generative
- symbols of language can be combined to generate an infinite number of messages
5. Permits Displacement
- can refer to objects or events that are not physically present
What is the difference between phonemes and morphemes?
Language is hierarchical;
- sounds/letters→words→phrases→sentences→conversation/paragraphs/etc.
Phonemes:
- most basic unit of speech sounds
- specific sets of phonemes in each language
- English: ~45
- Hawaiian: ~11
- changing phoneme changes meaning of the word
Morphemes:
- smallest units of meaning in a language
- some are words, some are suffixes/prefixes
- eg. kitchen, bedroom, pig
What do the terms syntax, semantics, and pragmatics refer to?
Semantics:
- meaning of words and sentences
Syntax:
- grammatical rules that govern how we organize words into sentences
- related to the fact that language is structured
- Grammar encompasses both syntax and morphology (study of how we create words by combining morphemes)
Pragmatics:
- knowledge of the practical application of language
- social rules (+context) that can affect understanding and word choice
- eg. *Do you have the time? * Yes.
- based on context, can infer what the question implies
- formal vs. informal situations
What is the difference between surface and deep structure?
Can a phrase have the same surface and different deep structure (or vice versa)?
Surface structure:
- words that are actually spoken (or written/signed)
Deep structure:
- underlying meaning of the sentence
Briefly describe the difference between bottom-up and top-down processing in language comprehension. Examples?
Bottom-Up Processing:
- combine very simple elements into more complex things
-
Spoken language:
phonemes→morphemes→words→phrases… -
Written language:
contours/line angles→letters→words→phrases… - Note: “letters→words” jump can happen directly (visually recognizing pattern of letters) or indirectly (when we sound the letters and recognize the sound of the word in our head)
-
Spoken language:
Top-Down Processing:
- context, attention, organization affects processing; knowledge of what’s likely…
- interpretation of letters on the context (other letters)
- similarly, context can influence whole words
What information do humans use to segment speech into words? Does speech segmentation support bottom-up or top-down models?
- use of top-down knowledge; context helps us perceive speech in our own language
- perceive speech as a series of separate words…
- usually bigger decreases in energy output within words than there are between them
- phonemes overlap & affect each other; while saying one phoneme, your mouth is already starting to form the next one:
- need to know the previous/next phonemes (context) to figure out which phoneme someone was trying to say
Language production/comprehension involve which brain areas?
Broca’s Area:
- located in the left frontal lobe
- responsible for language production
- involved in grammar, finding the right word
- necessary for articulating/producing words
-
Broca’s Aphasia: impairment in language production due to damage to Broca’s area
- can be temporary/permanent
- damage does NOT affect comprehension
Wernicke’s Area:
- located in the left temporal lobe
- responsible for language comprehension
- necessary for understanding
-
Wernicke’s Aphasia: impairment in language comprehension due to damage to Wernicke’s area
- can be temporary/permanent
- often characterized by “babbling”; words are pronounced correctly, but the meaning is not clear
- damage does NOT affect language production
Describe how language is lateralized (including the functions of each hemisphere). Describe the sex difference in lateralization.
Both Broca’s & Wernicke’s areas = left hemisphere
∴abilities specific to language are lateralized on left
Problems:
1. Some people are less laterlized
- women & left-handed people are less laterlized
- eg. women with L. hemisphere stroke show less language impairment than men w/ same damage
2. Recent studies shows that the right hemisphere has specific functions in language too!
-
left hemisphere:
- __heavily involved in speech perception
- more active when searching for word meanings, reading high-imagery sentences
-
right hemisphere:
- __involved in linking elements of a story together
- becomes activated to help resolve ambiguities
Briefly outline the evidence that language has a biological foundation and the evidence for a social learning component.
Differentiate between the LAD and LASS.
Nature and Nurture:
Biological Foundations:
1. Innate ability for children to learn language
- young children are limited in terms of complex thought
- learn language quickly/easily
2. All children develop language
- progress through the same stages of language development - regardless of language
3. Chomsky suggested all languages share a “universal grammar” of noun & verb phrases
- Born w/ Language Acquisition Device (LAD)
- can be “programmed” for any specific language
Social Learning Process:
Social environment builds upon the biological foundation w/ a social suppot system for learning; Language Acquisition Support System (LASS)
1. Child-directed speech (“motherese”)
- high-pitched sing-song used all over the world
2. Direct teaching of vocabulary
- direct attention and say word “cat”
Describe how children’s phoneme discrimination supports both aspects of both biological and social environments.
Phoneme discrimination:
- No language uses all of the possible phonemes
- HOWEVER, up to 6 months of age, *all *kids can discriminate ALL THE WORLD’S phonemes - even those that aren’t used in their language!
⇒ Biological ability - Between 6-12 months old, children lose this ability, and learn to focus only on the phonemes of their environment
⇒ Social influence
Describe each stage of the developmental timeline for language learning, including the typical ages for each stage.
Children of all cultures go through the same stages when learning their 1st language:
1. Cooing; (1-3 mo.)
- able to distinguish speech from non-speech
2. Babbling; (4-6 mo.)
- able to vocalize in response to others
3. “Lalling” (7-11 mo.)
- begins to use tongue (“lalling”)
- phoneme discrimination narrows only to those phonemes of the others in the environment
4. First word (12 mo.)
- usually familiar person/object
5. Single-word requests (12-18 mo.)
- eg. “milk” or “out”
6. Telegraphic speech (18-24 mo.)
- “want cookie!” or “mommy drive car”
- non-essential words are left out
7. Vocabulary explosion! (2-4 yrs.)
- more complete sentences, w/ only fairly minor grammar violations
- eg. “Ginger is playing with two fishes!”
8. Complete sentences (4-5 yrs.)
- sentences complete w/ correct (basic) grammar
Briefly outline the costs & benefits of learning a second language.
Pros:
- score higher in most performance tests than monolinguals = better grades
- higher self-esteem, controlling attention & thought - better at tuning out irrelevant info ∵ must inhibit one language while speaking the other
- tend to have lower incidences of demential & Alzheimer’s disease
Cons:
- tendency to have smaller vocabulary for each language than monolinguals
- adults have more tip-of-the-tongue experiences
- slower, less accurate in naming pictures or making word/non-word judgments
