Semantics
|
the study of meaning; built on syntax
|
|
compositionality
|
the meaning of a larger expression is a function of: the meaning of its parts and the syntactic rules that are used to combine them
|
|
Referential Theory
|
the meaning of an expression is its reference
|
|
reference
|
the things in the world it picks out
|
|
co-reference
|
an expression that picks out the same thing as another expression
|
|
Law of Identity
|
an expression can be substituted for another expression with the same value
|
|
Gottlob Frege
|
substitutions changes the meaning
->meaning isn't simply reference |
|
Sense
|
additional concept of how we see an expression (what we think of)
-substitution is only possible if two expressions have the same sense |
|
First words
|
names of people,common nouns, modifiers,actions, social interactions
-ex: apple, airplane, belly-button, book, bye-bye, car, daddy, dog, eye, light, mommy, uh-oh |
|
Ostention
|
adult points and says name; children assoc. name with objects
|
|
Biases in Learning the Meanings of Words
|
noun bias, whole object bias, taxonomic bias, mutual exclusion bias, basic level category bias
|
|
noun bias
|
most kids first words are nouns
-why?: maybe cause nouns more straightforward or because you need to know nouns for verbs |
|
whole object bias
|
kids interpret a label as applying to a whole object rather than action, attribute, or parts of an object
|
|
taxonomic bias
|
interpret labels as referring to objects of the same kind, not objects which are related to each other in diff ways
|
|
mutual exclusivity bias
|
a new label should refer to an object without an existing label
-if object already has a label, kids think the new label may refer to a part of the object |
|
basic level category bias
|
children interpret labels as referring to the basic level
|
|
errors in vocabulary learning
|
1-over and under extension
2-misunderstanding of concepts |
|
theory of mind
|
children must understand an adult's referential intentions to learn words this way
-kids use gazes and other cues |
|
front lobe
|
-primary motor cortex
-motor control |
|
temporal lobe
|
-auditory cortex
-hearing |
|
occipital lobe
|
-visual cortex
|
|
Parietal lobe
|
-spatial reasoning
|
|
H.M.
|
-parts of temporal lobes (including L and R hippocampus) taken out to help his epilepsy
-then had anterograde amnesia (can't form new long-term memories) -hippocampus responsible for changing short-term memory to long-term |
|
Modularity Hypothesis
|
certain cognitive functions are organized into autonomous modules (faculties)
-UG is a Faculty of Lang. (there is a module in brain that is specifically dedicated to language) |
|
Up to age... brain can recover function after injury.
|
5
-if left hemisphere (where lang function usually is), it can be lateralized to right perisylvan region |
|
Plasticity declines between .... and ...
|
5 and 13
|
|
Broca's Area
|
assoc. with production of speech
|
|
Wernicke's area
|
assoc. with comprehension of language
|
|
Aphasia
|
-language disruption caused by damage of brain
|
|
Broca's Aphasia
|
Agrammatical utterances (many grammatical errors)
-slow, effortful production -comprehension better than production -lots of content words, lack of function words |
|
Wernicke's Aphasia
|
-fluent speech, but deprived of content
-word-finding problems -difficulties in understanding others |
|
Misconceptions about SL
|
-there's only one universal sign lang.
-completely iconic -ASL is a manual-visual translation of English (NO:grammar is different, sign lang not representations of lang. around them) |
|
SEE
|
Signing Exact English--> made-up signing system, not natural
|
|
duality of patterning
|
-combination of meaningful units to form more complex ones
-combination of minimal meaningless units to form larger, meaningful ones |
|
Duality of PAtterning in sign lang.
|
-meaningless units: handshape, movement, location
-meaningful units: signs |
|
SVO
|
Subject-Verb-Object
|
|
Sign Lang. Milestones:
|
-6 months-one year: manual babbling
-first signs as early as 6 months (earlier than spoken lang -18 months: word combinations (as in hearing) |
|
Lingua Franca
|
a standard language used for communication between speakers of different languages
|
|
Pidgin
|
a communication system which develops when speakers share no common language
-no stable vocab -no consistent word order -only simple sentences -mainly content words |
|
substrate lang.
|
the original native lang. of the speakers
|
|
superstrate lang
|
the language used by the dominant socioeconomic class
|
|
lexifier language
|
the lang that is the source for most of the vocab (often the superstrate lang)
|
|
Creole
|
when kids exposed to pidgin as the lang of their care-givers, a creole develops
-opposite of pidgin characteristics -grammer is stable across speakers -elements in it not part of sub or superstrate lang -grammar consistent with UG principles and parameters |
|
Hawai'i Creole English
|
-from laborers from China, Portugal, Korea, etc on sugarcane plantations
-pidgin became creole around 1900 |
|
Home sign
|
when deaf kids not exposed to SL thy develop a gesture system to communicate
-not full lang -pointing signs -characterizing and action signs -simple combos--> consistent SOV order -not from adult models |
