Unformatted text preview: oral lobe). Led to questioning of the modular classical model. Classic Models of Language Processing!
Broca’s area: responsible for expressive
language, or language production.!
Wernicke’s area: responsible for receptive
language, or language comprehension.!
Angular gyrus: responsible for comprehending
language-related visual input necessary for
reading and writing.!
Arcuate fasciculus: the white ﬁber pathway
that connects Wernicke’s area to Broca’s area.! The classical model is based on these areas that associated with language processing. Starting with Broca's area: it is found in the PFC and
responsible for language production. Wernicke's Area is the opposite: they have trouble with understanding, or language comprehension. The angular
gyrus sits in the parietal lobe; it is not always considered part of the language system but it is important for transforming visual word form and visual
information about language into an phonetic auditory system. So our language system is depending on hearing and being able to comprehend speech
is based on auditory input. If you are reading texts instead, you must have part of the brain that can transform the word forms into something the
language system can understand. Arcuate fasciculus: white tract bundle of ﬁbers that connects Wernicke's area to Broca's area. Important bc must
have a connection between what you are hearing and what you are saying.
These are the classic modules. Probably the most inﬂuential model of the early models is the wernicke-geschwind model. Classic Models of Language Processing!
The Wernicke-Geschwind Model of Language!
1. Information about the sound is analyzed by the
primary auditory cortex and transmitted to
2. Wernicke’s area analyzes the sound information to
determine the word that was said.! 3. This information from Wernicke’s area is
transmitted through the arcuate fasiculus to Broca’s
4. Broca’s area forms a motor plan to repeat the
word and sends that information to motor cortex.! 5. Motor cortex implements the plan, manipulating the lary...
