Chapter 9: Language
Language Unique to humansPresent in all culturesEssential for knowledge and culture
Without it, cultural transmission of information and the acquisition of knowledge would be much more limited
![Page 4: Cog5 lecppt chapter09](https://reader033.vdocuments.pub/reader033/viewer/2022061113/5457c1beaf795994188b5213/html5/thumbnails/4.jpg)
The Organization of Language
Thoughts become sounds
Sounds become thoughts
HOW? Hierarchical organization
![Page 5: Cog5 lecppt chapter09](https://reader033.vdocuments.pub/reader033/viewer/2022061113/5457c1beaf795994188b5213/html5/thumbnails/5.jpg)
The Organization of Language
Sentence—sequences of words Word—smallest free form Morpheme(詞素)— smallest unit of
meaning Phoneme(音素)— smallest unit of
sound
![Page 6: Cog5 lecppt chapter09](https://reader033.vdocuments.pub/reader033/viewer/2022061113/5457c1beaf795994188b5213/html5/thumbnails/6.jpg)
The Organization of Language
Hierarchical, with each level composed of other sublevels
![Page 7: Cog5 lecppt chapter09](https://reader033.vdocuments.pub/reader033/viewer/2022061113/5457c1beaf795994188b5213/html5/thumbnails/7.jpg)
Phonology
Flow of air from lungs
Modulationof air by mouthand nose
Production of phonemes
![Page 8: Cog5 lecppt chapter09](https://reader033.vdocuments.pub/reader033/viewer/2022061113/5457c1beaf795994188b5213/html5/thumbnails/8.jpg)
Phonology
Voicing Whether vocal folds (聲帶) vibrate ([z], [d], [b], [v]) Or not ([s], [t], [p], [f])
Manner of production Whether air is fully stopped ([b], [p], [d], [t]) Or merely restricted ([z], [s], [v], [f])
Place of articulation Where in the mouth the air is restricted
Closing of lips ([b], [p]) Top teeth against bottom lip ([v], [f]) Tongue behind upper teeth ([d], [t], [z], [s])
![Page 9: Cog5 lecppt chapter09](https://reader033.vdocuments.pub/reader033/viewer/2022061113/5457c1beaf795994188b5213/html5/thumbnails/9.jpg)
Phonology
Many words have no clear boundaries yet speech segmentation is effortless
Speech segmentation is the process of “slicing” the speech stream into words and phonemes.

Phonology
Coarticulation the blending of phonemes at word boundaries refers to how the production of each phoneme is slightly altered
depending on the preceding and following sounds. “My name is Dan Reisberg” “My name is Noam Chomsky”
S is slightly different
D and N are slightly different
![Page 12: Cog5 lecppt chapter09](https://reader033.vdocuments.pub/reader033/viewer/2022061113/5457c1beaf795994188b5213/html5/thumbnails/12.jpg)

Phonology
Continuous variation of sounds
are filtered toproduce clear phonemes
Categorical perceptionOur categorization of phonemes shows abrupt boundaries, even when there is no corresponding abrupt change in the stimuli themselves.
![Page 15: Cog5 lecppt chapter09](https://reader033.vdocuments.pub/reader033/viewer/2022061113/5457c1beaf795994188b5213/html5/thumbnails/15.jpg)
Phonology
Sequences Only some are acceptable in a language.
For example, the sequence [tl] is not acceptable in English
Adjustments for certain phoneme sequences. For example, the [s] sound becomes a [z] in words
like “bags”
![Page 16: Cog5 lecppt chapter09](https://reader033.vdocuments.pub/reader033/viewer/2022061113/5457c1beaf795994188b5213/html5/thumbnails/16.jpg)
Words
For each word that a speaker knows, there are several kinds of informationPhonology—the sequence of phonemes that
make up the wordOrthography—how the word is spelled (if the
person is literate)Syntax—how to combine the word with other
wordsSemantics—what the word means
![Page 17: Cog5 lecppt chapter09](https://reader033.vdocuments.pub/reader033/viewer/2022061113/5457c1beaf795994188b5213/html5/thumbnails/17.jpg)
Words
The referent is the actual object, action, or event in the world that a word refers toConceptual information A large part of “knowing a word” is knowing
the relevant concept
![Page 18: Cog5 lecppt chapter09](https://reader033.vdocuments.pub/reader033/viewer/2022061113/5457c1beaf795994188b5213/html5/thumbnails/18.jpg)
Words
GenerativityOur morphological knowledge specifies how
to create variations of each word by adding appropriate morphemes
New words can be formed “Hardware,” “software” lead to “spyware” and
“malware”
Words can take on new meanings “I have been hacked by a hacker.”
![Page 19: Cog5 lecppt chapter09](https://reader033.vdocuments.pub/reader033/viewer/2022061113/5457c1beaf795994188b5213/html5/thumbnails/19.jpg)
Syntax
Generativity Infinite number of sentences by combining finite
set of words For practical purposes, there is an infinitely large
number of sentences that speakers can produce in their language

Language and Thought
Linguistic relativity is the hypothesis that people who speak different languages think differently
Benjamin Whorf’s original argument was that Hopi speakers and English speakers think differently about time

Language and Thought
A language’s color categories may affect how its speakers perceive and remember color

Language and Thought
The spatial terminology of a language—for instance whether absolute or relative terms are used—may affect how its speakers perceive and remember spatial information

Language and Thought
One possibility for such results is that the language you speak determines the concepts and categories that you use, and as a result, shapes what you can think about
A more flexible possibility is that language influences what we pay attention to, and this shapes experience, which influences how we think
