Language
Our spoken, written, or gestured word, it is the way we communicate meaning to
ourselves and others.
Language transmits culture.

Language Structure
Phonemes: The smallest distinctive sound unit in a spoken language. For example:
bat, has three phonemes b · a · t
chat, has three phonemes ch · a · t

Language Structure
Morpheme: The smallest unit that carries meaning may be a word or a part of a word. For example:
Milk = milkPumpkin = pump . kin
Unforgettable = un · for · get · table

Grammar
A system of rules in a language that enables us to communicate with and understand others.

Semantics
Set of rules by which we derive meaning from morphemes, words, and sentences.
For example:
Semantic rule tells us that adding –ed to the word laugh means that it happened in
the past.

10
Syntax
The rules for combining words into grammatically sensible sentences. For example:
In English syntactical rule is that adjectives come before nouns; white house. In Spanish it is reversed; casa
blanca.

Language Development
Children learn their native languages
much before learning to add 2+2.
We learn on average (after age 1) 3,500
words a year, amassing 60,000
words by the time we graduate high school.

When do we learn language?
Babbling Stage: beginning at 4
months the infant spontaneously utters various sounds, like ah-goo. Babbling is
not imitation of adult speech.
![Page 13: Module 30, Myers 8e Psychology](https://reader034.fdocuments.us/reader034/viewer/2022042513/552871814a7959d8448b471f/html5/thumbnails/13.jpg)
13
When do we learn language?
One-Word Stage: Beginning at or around the first birthday, a child starts to speak one-word and makes family adults understand him. The word doggy may mean look at the dog out there.
![Page 14: Module 30, Myers 8e Psychology](https://reader034.fdocuments.us/reader034/viewer/2022042513/552871814a7959d8448b471f/html5/thumbnails/14.jpg)
14
When do we learn language?
Two-Word Stage: Before the 2nd year a child starts to speak in two-word sentences. This form of speech is called telegraphic speech in which the child speaks like a telegram —“go car,” means that, I would like to go for a ride in the car.
![Page 15: Module 30, Myers 8e Psychology](https://reader034.fdocuments.us/reader034/viewer/2022042513/552871814a7959d8448b471f/html5/thumbnails/15.jpg)
15
When do we learn language?
Longer phrases: After telegraphic speech children start uttering longer phrases (Mommy get ball), with syntactical sense and by early elementary school they are enjoying humor.
You never starve in the desert because of all the sand-which-is there.

Explaining Language Development
• Operant Learning: Skinner (1957, 1985) believed that language development can be explained on the basis of learning principles, such as association, imitation and reinforcement.
![Page 18: Module 30, Myers 8e Psychology](https://reader034.fdocuments.us/reader034/viewer/2022042513/552871814a7959d8448b471f/html5/thumbnails/18.jpg)

Explaining Language Development
2. Inborn Universal Grammar: Chomsky (1959, 1987) opposed Skinners ideas and suggested that rate of language acquisition is so fast that it cannot be explained through learning principles, and thus most of it was inborn.

Explaining Language Development
3. Statistical Learning and Critical periods: Well before our first birthday, our brains are discerning word breaks by statistically analyzing which syllables in hap-py-ba-by go together. These statistical analysis are learned during critical periods of child development.

Genes, Brain & Language
Genes design the mechanisms for a language, and experience modifies the
brain.

Language influences Thinking
Linguistic Determinism: Whorf’s (1956) suggested that language determines the way we think, e.g., Hopi, he noted, did not have past tense for verbs therefore Hopis could not think readily about the past.
![Page 24: Module 30, Myers 8e Psychology](https://reader034.fdocuments.us/reader034/viewer/2022042513/552871814a7959d8448b471f/html5/thumbnails/24.jpg)
24
Language influences Thinking
When a language provides words for objects or events we can think about these objects more clearly and retain them. It is easier to think
about two colors with two different names (A) than colors with the same name (B) (Özgen,
2004).
![Page 25: Module 30, Myers 8e Psychology](https://reader034.fdocuments.us/reader034/viewer/2022042513/552871814a7959d8448b471f/html5/thumbnails/25.jpg)
25
Word Power
Increasing word power pays its dividends. It pays for speakers and deaf who learn a
sign language.

Linguistic Determinism Questioned
People from Papua New Guinea without our words for colors and shapes still
perceived them as we do (Rosch, 1974).

Thinking in Images
To a large extent thinking is language based. Like when alone we talk to ourselves.
However, we also think in images.

1. When we open the hot water tap.
We don’t think in words, when:

Images and Brain
Imagining a physical activity activates the same brain regions as when actually
performing the activity.

Traffic runs both ways between thinking and language.

Do animals have a language?
Animals & Language
Honey bees communicate by dancing. The dancemoves clearly indicate the direction of the nectar.

Mental States
Can animals infer mental states in themselves and others?
To some extent. Chimps and orangutans (and dolphins) have used mirrors to
inspect themselves if a researcher has put a paint spot on their face or bodies.

communicate.

37
The Case of Apes
Chimps do not have vocal apparatus for human-like speech (Hayes & Hayes,1951).
Gardner and Gardner (1969) therefore used American Sign Language (ASL) to train
Washoe (a chimp), who learnt 182 signs by age 32.
![Page 38: Module 30, Myers 8e Psychology](https://reader034.fdocuments.us/reader034/viewer/2022042513/552871814a7959d8448b471f/html5/thumbnails/38.jpg)
38
Gestured Communication
Animals show communication through gestures as do humans. It is possible that
vocal speech developed from gestures during evolution.

Sign Language
American Sign Language (ASL) has been instrumental in teaching a
communication form to chimpanzees.
When asked, chimpanzee usesa sign to say it is a baby

Computer Assisted Language
Others have shown that bonobo pygmy chimpanzees can learn even larger vocabularies
and perhaps semantic nuances in learning language (Savage-Rumbaugh, 1991). Kanzi and
Panbanish developed vocabulary for hundreds of words and phrases.

Criticism
1. Apes gain their limited vocabularies with great deal of difficulty unlike children who develop vocabularies at amazing rates.
2. Chimpanzees can make signs to get rewards, just as pigeon pecks at the key gets reward. But pigeon has not learnt a language.
3. Chimpanzees use signs meaningfully but lack syntax.
4. Presented with ambiguous information people tend to see what they want to see.

Conclusions
If we say that animals can use meaningful sequences of signs to communicate means
language, our understanding would be naive… Steven Pinker (1995) concludes,
“chimps do not develop language.”
