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 Wernicke’s area.! 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 area.! 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...
