Unformatted text preview: bc now isolated from people. What he
is saying sounds right, but has no connection to
the questions he is being asked. Probably has
issues reading as well, since visual word form has
to be transformed by the angular gyrus and then is
sent into Wernicke's area. Tend to be
institutionalized because they can't function,
whereas Broca's are not bc they often can ﬁnd
ways to communicate. Wernicke's patients use to
be lumped in w/ Schizophrenic patients.
Wernicke's are not always aware they have a
problem. Broca's patients are aware of their issue. Wernicke’s aphasia: problems in language comprehension! Brain Damage & Language Deﬁcits! Apraxia: problems in speech production!
Broca’s aphasia: problems in language production! Probably another module which includes "things about
the world" or stored knowledge (semantics). The
language system really depends on having access to
alot of stored knowledge. And damage to these areas
can lead to very speciﬁc loss of these processes. Wernicke’s aphasia: problems in language comprehension!
Anomic aphasia: problems in naming objects! Very different from Broca's aphasia. He was very smart guy w/ IQ 160,
and created medical supply co. in western Massachusetts. He is very
articulate & has a good way of being able to talk around his inability to
name objects. Naming object tends to be processed in inferotemporal
lobe, but the storage may be widely distributed. Clearly hasn't lost all
names of all objects, just certain objects. 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.! All this put together forms the Classical Theory of Language Processing. The usefulness...
