Sound, Meaning, and LanguageSound
MeaningLa

• Language is the tool to convey meaning – transforming mental states (meaning) to a commonly understood structure (spoken language sound)
Sound
Meaning

Charles Lutwidge Dodgson
• a.k.a. Lewis Carroll• Alice’s adventure in Wonderland, Jabberwocky• Literary nonsense• Portmanteau: a word that combines two words,
or morphemes, to give double meaning. E.g., DISDAQs Discarded and Deleted Acquisitions
• Conventions (grammar) without meaning• No meaning will be interpreted even if grammar
is preserved.
http://en.wikipedia.org/wiki/Lewis_Carroll

Dictionary and Thesaurus
• Is the meaning of language described in the dictionary and thesaurus?
• Old dictionaries only report literal meanings, but newer ones also report usage and give examples.
• Almost impossible to acquire meaning of new words from those already in the lexicon
especially in the early developmental stage

Meaning as Sounds?• Complicated matter…
• Sentence means more than each individual word
gestalt psychology: the whole > the sum of its parts
• Meaning of each word mental lexicon
• Grammar word order, inflection…etc.
• Prosody
• Usage culture
• Gesture

Irony and Sarcasm
• Meaning get reversed!
• Are they the same?
• “Sarcasm is a remark seasoned with irony.”
• Sarcasm has a entertaining purpose while irony could either be casual or serious.
• Sarcasm is the vehicle to reach both humour and irony.

Types of Meaning
• Meaning of individual words
• Meaning of combinations of words
![Page 9: PSYC 3640 Psychological Studies of Language How Words are Represented in Written Forms](https://reader035.vdocuments.net/reader035/viewer/2022062321/56812c62550346895d90f55a/html5/thumbnails/9.jpg)

Meaning of Individual Word• Knowledge that one has of the situations or
contexts in which it would be appropriate to use that word
• In the brain: event occurs when “some particular neural circuitry somewhere in the brain is stimulated into activation”
linguist fish

10
Neural Network of Meaning• Or should I say concept associated with
each word?• My understanding of a “linguist” could be
different from yours!
linguist
![Page 11: PSYC 3640 Psychological Studies of Language How Words are Represented in Written Forms](https://reader035.vdocuments.net/reader035/viewer/2022062321/56812c62550346895d90f55a/html5/thumbnails/11.jpg)
11
Does it matter?• Unique neural network for each person• Some more extensive, some more confined• As long as the neural networks of ‘linguist’ are
activated in the same context, they will elicit some common understanding between the two individuals.
• Important: sounds of ‘linguist’ activate the linguist network, sounds of ‘fish’ activate the fish network
• Does the distinction ability mean understanding?

Experience
![Page 13: PSYC 3640 Psychological Studies of Language How Words are Represented in Written Forms](https://reader035.vdocuments.net/reader035/viewer/2022062321/56812c62550346895d90f55a/html5/thumbnails/13.jpg)
13
Experience• Pattern of neural activities changes as a function of
accumulated experience (physical characteristics and context in which an individual encounters)
• Neural activities reflects experiences• Similar things also happen in similar context and elicit
similar experience similar pattern of neural activities
• Meaning concepts about a particular entity that is influenced by experience of interacting with that entity concepts of similar entities are overlapped because of similar associated contexts

• Environmental enrichment
• Bilingualism
• Drugs
• Nutrition
• Meditation??

Studying the Mind
• Logicians in Philosophy• Alan Granham
– Meaning as mental equivalent of the language used to describe something
– Meaning as mental equivalent what happens when one observes that something directly
By the window was a man with a martini.
The man with the martini waved at the hostess
The man by the window waved at the hostess

Mental Worlds• The entity that we want to communicate to
others via language• Endless possibilities!
The winged unicorn flew high across the fiery skies.

Materializing Mental Models
• Lego models:
One-to-one mapping between model components and real-world entity components
• Mental models:
One-to-one mapping between the neural activity that corresponds to the mental model and the neural activity that corresponds to the actual experience
![Page 21: PSYC 3640 Psychological Studies of Language How Words are Represented in Written Forms](https://reader035.vdocuments.net/reader035/viewer/2022062321/56812c62550346895d90f55a/html5/thumbnails/21.jpg)
21
Building a Mental Model
• Mental model’s lifetime exceeds that of the duration of the sentence.
• New sentences update the ever-changing mental model
• We also make predictions when we read.

Words with Intangible Meanings
In the mid-1990s, it was believed that a change of government would do the country some good.
Try drawing a picture for each of the word in that sentence…

Summary of Chapter 9• Language is the tool to bridge together sound and
meaning.• Sentence comprehension reflects the combination
of semantics and syntax is far greater than the total semantics of each individual word.
• Meaning interpretation is influenced by experience and is related to activation of a neural network of a particular word concept of a word
• Meaning is also a channel to access mental models, which is not restricted by the physical characteristics of the physical world.

Written Languages
• Spoken language does not last long.
• Written language is the channel that cradles culture and civilization.
• Earliest purpose of written languages is for trading ledgers
• Early writings are pictorial-based hieroglyphic writing system: words made up of pictures and sounds.

Early Forms of Writing
http://mulibraries.missouri.edu/specialcollections/exhibits/cuneiformmain.htm
Cuneiform from Mesopotamia
Egyptian demotic script
http://www.lib.umich.edu/pap/exhibits/writing/demotic.html
![Page 26: PSYC 3640 Psychological Studies of Language How Words are Represented in Written Forms](https://reader035.vdocuments.net/reader035/viewer/2022062321/56812c62550346895d90f55a/html5/thumbnails/26.jpg)
26
Evolving into an Efficient Writing System
• Written symbols refer to spoken languages rather than the actual entity
• Developing phonetic symbols to represent individual sounds
• Used in hieroglyphic and cuneiform scripts
• Combining phonemes
• Adopt different pitch patterns
![Page 27: PSYC 3640 Psychological Studies of Language How Words are Represented in Written Forms](https://reader035.vdocuments.net/reader035/viewer/2022062321/56812c62550346895d90f55a/html5/thumbnails/27.jpg)
27
Non-alphabetic Writing Systems• Logograms: Chinese• Pictophonetic compounds
– Semantic radicals signify meaning– Phonetic radicals signify sounds
• But only 40% accuracy in sounding out the phonetic radicals
媽Means “female”
Sounds “nü”
Means “horse”
Sounds “ma”
Means “mother”
Sounds “ma”
![Page 28: PSYC 3640 Psychological Studies of Language How Words are Represented in Written Forms](https://reader035.vdocuments.net/reader035/viewer/2022062321/56812c62550346895d90f55a/html5/thumbnails/28.jpg)
28
Syllabaries • Japanese• Three types of written representations:
– Hiragana: syllables represent original Japanese words– Katagana: syllables represent imported words– Kanji: Chinese characters
ビール Means “beer”
Sounds “bii-ru”
すし 寿司 Means “sushi”
Sounds “su-shi”
hiragana kataganakanji

29
Learning to Read• Home environment• Written representation of sounds
– Phonemic level– Syllabic level
• Transparency of grapheme-phoneme-correspondence (GPC)
• English: letter names ≠ letter sounds!!
• Whole-word approach using recognition

31
Dual-route Access
• Recall Reynolds & Besner (2005) paper? DRC model describes exactly this situation
• Lexical route: whole-word approach because the words are already in the lexicon
• Non-lexical route: phonics approach because need to sound out the letters to help search for the meaning of the word
