Lecture 19: Speech and Language Flashcards
is attention lateralized in the left of right parietal lobe
right lobe
is language reception and expression is lateralized to the left or right side of the brain
left
what is the Broca’s area
in frontal lobe
Activates particular sequences of sounds to produce words and sentences (language production)
what is the Wernicke’s area
in the temporal lobe
Identifies and comprehends particular sequences of sounds as meaningful words.
(language comprehension)
what is the Arcuate Fasciculus
Connects Broca with Wernicke
are the Broca, Wernicke, and the arcuate fasciculus the only areas involved in language
they are they key structures, but Many other areas/connections are required for complex functions.
what is aphasia
Lack of language abilities, but not due to purely motor problem (dysarthria) or purely sensory problem (deafness)
what are the 2 kinds of aphasia
Broca (or expressive) aphasia
Wernicke (or receptive) aphasia
what is Broca (or expressive) aphasia
Difficulty in saying words, but nothing wrong with muscles
Decreased fluency and phrase length
Comprehension of the speech of others is good
what is Wernicke (or receptive) aphasia
Difficulty comprehending
speech
High verbal output & fluency
Can’t understand their own speech, therefore often utter “word salad”
how does a left sided stroke affect deaf people
“sign aphasia”
how does a right sided stroke affect deaf people
decreasing emotion in signing
what part of speech is affected by damage to the right part of the brain
prosody - emotion conveyed by tone of voice
what are the 3 steps that happens when someone hears “repeat after me”
wernicke’s area hears the words and understands what they mean
that information travels trough the arcuate fasciculus
it reaches the broca’s area, where the person will think of the words they want to say, and gets them to spit out the produce sounds
when deaf babies learn to use sign language, which parts of the brain light up
motor AND Language parts
