Content Objectives• Our mission for this week will be:

– To explore the properties of language.– To understand the key concepts regarding

first language acquisition.– To learn about the brain and language

processing.– To learn how to use context clues to

understand meanings.

Language Objectives• We will accomplish our mission by:

– Discussing the properties of language using “What is language in Pictures & Words”.

– Individually writing responses to opening discussion cases associated with key concepts.

– Discussing in a group our understanding of brain areas used for language processing

– After reading a passage, complete exercises on using definitions, details, and examples to understand meanings.

Opening Discussion Case 1• How do you pronounce this made-up word:

“wug”? - /wʌg/

• How about “nghalmax”? Why do you have a problem pronouncing this non-word compared to the first one?

Opening Discussion Case 2

• When making a singular verb into a plural form, how do you know whether to add

an /s/ sound as in “pits” and “sinks”, a /z/ sound as in “lids” and “pens”, or an /əz/ sound as in “watches” and “lodges”?

• Why do we say ‘happier” and “prettiest”, but “more upset” and “most excited?”

Opening Discussion Case 3

Opening Discussion Case 4• Why would a child say each of the

following “errors?” What does this tell you about first language acquisition?

(1) Child: “Daddy bringed me my shoes for my foots.”*

(2) Adult: Who broke the window?”

Child: Well, perhaps it was John, but perhapser it was Mary.”*

COURSE SYLLABUS

• Overview

• Assignments

• Due Dates

• Questions???

What are the properties of language?

• Communicative: Language = primary form of communication

• Arbitrary relationship to referents (e.g., dog - perro)• Systematic (patterns based on rules) • Generative/productive – We can generate an infinite

# of sentences out of a finite set of rules (Chomsky)• Evolutionary – language changes over time; new

words are coined every year (e.g., blog)• Cultural/conventional - symbols and their meanings

represent shared values among a group of people

What are the properties of language?

• All of the Above!

• Linguists are interested in the

communicative, arbitrary, systematic,

generative, evolutionary, and culturally

specific nature of human language and

communication.

1. First Language Acquisition & Behaviorism

(F & F, pp. 1-4): B.F. Skinner (1957) – Language is learned through imitation (Stimlus Response Reinforcement).

2. Insights from Linguistics (F & F, pp. 10-11): N. Chomsky (1959) – Critique of Skinner; Language is too complex to be learned by imitation and reinforcement.

From a Behaviorist View to a nativist/innatist view of Language

Acquisition

Behavioral psychologists’ theory of language learning

Stimulus: what’s taught/presented

Response: learners’ response to the stimulus

(+)Reinforcement (praising): increases desired behavior (habit)

Norm Chomsky

Chomsky’s Major Contribution to Language Studies:

– Generative Grammar (the human brain can generate an infinite no. of sentences from a finite set of rules/words).

– Universal Grammar (innate linguistic knowledge that is common to all human languages) i.e., Language Acquisition Device (LAD) p. 13

This is your brain…

• There are about 100 -200 billion nerve cells, or neurons in the human brain.• The brain also contains up to 5 trillion support cells.• Many brain neurons last for a lifetime, but between the

ages of 20 and 60, adults lose about 12,000 neurons each day that can never be replaced.

• The brain is about 90% water.• The brain uses about 20% of our energy.• The brain weighs about 3 pounds.

Brain Development

• Growth of the brain

occurs from the inside out

and the bottom up

• You are born with

100 billion brain cells.

• There are ~ 15,000 synaptic connections for each

cell.

Neural Development

• The neurons in a child’s brain make more connections than those in adults.

• The more connections made between axons (output of the cells) and dendrites (input to the cells from the axons), the more memories occur.

• The richer the environment, the more interconnections are made and learning can occur faster and with greater meaning.

Language

Learning language is an early “test” of our brain’s learning system

• It requires core learning/thinking skills we will use throughout our lives.

• It develops the main learning tool students need – oral language.

• Left lobe/hemisphere– Most language functions (speech, listening, reading, writing)– Logical thought (writing, logic)

• “The explainer”

• Right lobe/hemisphere– Spatial-relation functions – Perception of rhythm & music, abstract or intuitive thought– Some language functions:

• Pragmatics, sarcasm, inferences, figurative language (e.g., metaphors)

The Brain & Language

The 2 hemispheres differ in terms of language

http://da.biostr.washington.edu/DA-ATLASES/Neuroanatomy/DAmovies/brainlobesX.mov

2 key left hemisphere brain areas involved in language: Broca’s Area

an area of the left frontal lobe involved in speech production, grammar, and using grammar for comprehension

Wernicke’s Area an area of the left temporal lobe

involved in language comprehension

The Brain & Language

Broca’s Area and Wernicke’s Area: 2 of the first brain areas discovered to have

specific functions (Broca, 1861; Wernicke, 1874)

Discovered through working with patients having severe language difficulties.

After death, these patients were found to have brain damage in consistent areas.

The Brain & Language

Aphasia Language impairment, usually caused by left

hemisphere damage either to Broca’s area (impairing speech & grammar) or to Wernicke’s area (impairing speech planning & language comprehension)

The Brain & Language

Broca’s Aphasia

Broca’s aphasia: This language disorder is characterized by omission of function words.

EX. “I eggs and eat and drink coffee breakfast”*

Broca’s area The brain of Broca’s

first aphasic patient, ‘Tan’

Could only say “tan” The brain area now

known as Broca’s area.

We can now experimentally induce temporary Broca’s aphasia using TMS Effects of TMS (transcranial magnetic stimulation)

to Broca's area:

Aphasia Language impairment, usually caused by left

hemisphere damage either to Broca’s area (impairing speech & grammar) or to Wernicke’s area (impairing speech planning & language comprehension)

The Brain & Language

Recapping the Brain and Language

• Speech comprehension– Area of the left

temporal lobe– Wernicke’s Area

(receptive region in left hemisphere) allows us to comprehend speech and put words into correct order when speaking.

Wernicke’s Aphasia• Someone

suffering from this language disorder can actually produce very fluent speech, but often difficult to make sense of.

The Brain and Language• Seeing Words

– Occipital Lobe– Primary center for

processing visual stimuli.

– Visual stimuli are not meaningful until sensory perceptions are matched with previously stored cognitive associations.

Brain Areas Involved in Reading Words Aloud

Bilinguals’ brain activations for L1 & L2: Are L1 and L2 represented together (same

areas) or separately in the brain? Does this differ for comprehension vs. speech

production & grammar? Does this differ between early or late L2

learners?

The Bilingual Brain

The Bilingual Brain• Let’s watch “The Bilingual Brain” to

learn how language helps us to understand more about our brains.

All Bilinguals’ activity in Wernicke’s Area:

Kim et al. (1997)

The Bilingual Brain

Typical subject (n = 12)

Both Early & Late bilinguals similar activation of Wernicke’s area for L1 & L2

Early Bilinguals’ activity in Broca’s Area:

The Bilingual Brain

Typical early bilingual (n = 6)

Early bilinguals: similar activation of Broca’s area for L1 & L2

Kim et al. (1997)

Late Bilinguals’ activity in Broca’s Area:

The Bilingual Brain

All 6 late bilingualsTypical late bilingual (n = 6)

Late bilinguals: different parts of Broca’s area activated for L1 vs. L2

Kim et al. (1997)

Fluent bilinguals’ brain activations for L1 & L2: Comprehension area may be the same for both L1 &

L2, but speech production area (e.g., pronunciation) may differ if L2 is acquired late (Kim et al., 1997).

Similar findings of shared vs. separate areas for early vs. late L2 learners in many studies (Fabbro, 2001).

• What does the brain imaging tell you about bilingual processing?

• How would you incorporate this information into bilingual education?

The Bilingual Brain

The Brain and Language

• Among early bilinguals, L1 and L2 are in the

same brain region and processed by the

same neural devices.

• For later bilinguals, some brain areas (within

Broca’s area) are different for L1 & L2.

Language, Thinking and Learning

• Language shapes cognitive (thinking) process and vice versa.

The Brain Mechanism and Language Processing

• Eliminate Irrelevant Information– Skilled learners eliminate irrelevant information for

better comprehension– Gernsbacker (1993, 1995)

– Bilinguals’ ability to inhibit L1 to allow L2

production to proceed (Kroll, 2010).

• Enrich the Environment– The more enriched the environment is, the more

dendritic branching occurs for better performance

(Greenough et al., 1992)

Implications for Teaching

• Teachers can apply brain mechanisms

to guide their students to focus on key

information by eliminating unnecessary

details while reading.

• Engage students in activities to promote

interactions and making connections.

Using top-down information to predict text content

• Rely on top-down information (e.g., titles, headings, and illustrations) to predict the content of the text

• Activating their knowledge of the world.• What is your prediction about chapter

three of the course text?

Using context clues to understand meanings

• Context clues = learn new words by paying attention to the other words in the sentence (Yaworski, 2006, pp. 78-87).

1) Definitions

2) Details

3) Examples

1) Definitions• Authors define new terms with in the

context of a sentence by setting the definition apart with the verbs (is/are, is/are called, is/are known as).

Ex. A professional portfolio is a collection of work that documents an individual’s accomplishments in an area of professional practice.

Exercise1-a: Definitions• Identify the key term being defined with its

definition.• A practicum is a short-term field-based

experience that allows teacher education students to spend time observing and assisting in classrooms.

• What is the term being defined: ________• Underline its definition.

Exercise1-b: Definitions• According to many psychologists

phobias are irrational fears represent symbolic repressed anxiety. The most useful treatment has been behavior-modification therapy.

• A phobia is: (a) a psychologist, (b) fear, (c) symbol, (d) treatment

2) Details• The term rhythmic is often used to

describe music that features simple patterns, such as ONE two ONE two, repeating over and over again, but that is not really correct. Such patterns should be described as metrical, or strongly metrical, not rhythmic.

Exercise 2-a: Details

• Identify the key term being defined and create a definition from the details.

• The basic unit for measuring time in music is the beat. When listening to a marching band, to take a clear example, we surely sense a regular recurrence of short durational units.

• What is the term being defined?: ________• What is its definition?:___________________

____________________________________

Exercise 2-b: Details• Oral history or the use of the tape recorder to capture

memories of the past in private interviews, has become increasingly popular among professional historians. American historians interviewed people about their experiences during important events such as the Great Depression.

• Oral history is: (a) private interviews, (b) the recording of people’s memories, (c) experiences during important events, (d) the history of tape-recording

3) Examples• Prices serve as signals to producers and

consumers. If consumers want more of any good, the price will rise, sending a signal to producers that more supply is needed. For instance, when a terrible disease reduces beef production, the supply of beef decreases and raises the price of hamburgers. The higher

Exercise 3-a: Examples• Identify the term being defined and find

examples that support the meaning.• Creatures such as the camel and the penguin

are so highly specialized that they can only live in certain areas of the world.

• Term: _________________• Examples:____________________________

____________________________________

Exercise 3-b: Examples• Much can be done to stop the process of

desertification. For example, as asphalt can be sprayed onto sand dunes, and seeds of trees and shrubs can then be planted. The oil stabilizes the sand and retains moisture, allowing vegetation to become established where the desert had previously taken over.

• Desertification is the: (a) spraying of oil onto sand dunes, (b) planting of trees and shrubs, (c) vegetation becoming established, (d) desert taking over a fertile area
