L XI, C XII Flashcards
Phonology =
Sound patterns of a language in some system of rules.
Syntax =
Rules for arranging items into possible permissible combinations.
Semantics =
Analysis of the meaning of language.
Chomsky states that…
Children are born with knowledge of language (innate) - a universal grammar.
Chomsky’s theory is in contrast with…
Associative/connectionist/usage-based theories, who state that language is learned, not innate.
Structure sensitivity =
How words/phrases are structured determines the interpretation of the meaning.
Broca’s area (BA?) + Broca’s aphasia
BA44/BA45 - responsible for producing speech and language.
Broca’s aphasia = understanding and IQ intact, speech distorted.
Wernicke’s area (BA?) + Wernicke’s aphasia
BA22 - responsible for understanding and processing language.
Wernicke’s aphasia = speech intact (but meaningless), understanding + IQ distorted.
Right hemisphere damage usually causes…
Mild deficits, like aprosodia.
Aprosodia =
Inability to properly convey/interpret emotional content of spoken language
Stereognosis =
Ability to perceive and recognize form of object in absence of visual/auditory information, using tactile information.
Left hemisphere versus right hemisphere
Left versus right:
- Right visual field versus left visual field
- Stereognosis right hand versus left hand
- Lexical + syntactical language versus emotional coloring language
- Writing versus spatial abilities
- Speech versus rudimentary speech
BA44/? in the IFG is responsible for…, via the … pathways, in interaction with the …
Pars opercularis - the assembly of hierarchical structures and complex sentence processing, via the dorsal pathways, in interaction with the STC.
STC supports integration of … and … information to achieve sentence interpretation.
Syntactic and semantic
STC-PMC connection is … and supports …
Innate, auditory-based phonological learning
In infants, the connection between … and … is not as well established as in adults.
In contrast, the … and the PMC are well connected in infants.
BA22/Wernicke and BA44/BA45/Broca
BA22/Wernicke and PMC
BA45/…, BA47/…, and anterior/posterior temporal cortex are involved in … via the … pathways.
BA45/pars triangularis, BA47/vlPFC
Complex language processing
Ventral pathways
Ventral system reflects … interface that involves … and …
That is retrieval and manipulation of … information.
Internal interfaces, semantics and reasoning
Semantic
Dorsal =
Ventral =
Dorsal = where, how Ventral = what
2 subdivisions of the syntactic rules and representations
External sensory-motor interface
Internal conceptual-intentional interface
Dorsal language system - areas and function
BA44/pars opercularis
Ordering words in hierarchically structured sentences
With PTC, comprehension of complex sentences
Ventral language system - areas and function
BA45/pars triangularis, BA47/IFG/vlPFC, temporal cortex
Processing of semantic information
… seems to distinguish between real and unreal grammar.
Broca’s area
FOX2-gene in the K.E. family
Inability to fluently select the movements needed to make appropriate speech sounds.
… lesions in birds impair … but not … - this is a neural dissocation.
NCM lesions
Recognition but not production
