19 HUMAN COMMUNICATION Flashcards
region of inferior FRONTAL LOBE which = important for PRODUCTION of words
BROCA’S AREA
region of AUDITORY ASSOC CORTEX on left TEMPORAL LOBE which = important for COMPREHENSION of words + production of MEANINGFUL speech
WERNICKE’S AREA
test used to determine hemispheric dominance for lang by injecting sodium amytal into right/left carotid artery which puts half of brain to sleep
WADA TEST
brain surgery occasionally performed to treat form fo epilepsy in which surgeon cuts CORPUS CALLOSUM
SPLIT BRIAN OPERATION
difficulty producing/comprehending speech caused by brain damage
APHASIA
difficulty PRODUCING speech caused by damage to BROCA’S AREA
BROCA’S APHASIA
- AGRAMMATISM
- ANOMIA
- difficulty w word articulation
3 MAJOR SPEECH DIFFICULTIES OF BROCA’S APHASIA
difficulty using GRAMMAR rules
AGRAMMATISM
difficulty finding appropriate words
ANOMIA
difficulty COMPREHENDING speech caused by damage to neural circuits in WERNICKE’S AREA
WERNICKE’S APHASIA
- PURE WORD DEAFNESS
- TRANSCORTICAL SENSORY APHASIA
- conversion of thoughts into words
3 MAJOR COMPREHENSION DIFFICULTIES OF WERNICKE’S APHASIA
disruption of inputs to WERNICKE’S AREA which results in INABILITY to UNDERSTAND speech that involves poor recognition of spoken words but ability to hear/speak/read/write without comprehending meaning of speech
PURE WORD DEAFNESS
deficit in which person can REPEAT statements but does NOT comprehend the statements
TRANSCORTICAL SENSORY APHASIA
(OPPOSITE OF TSA): inability to REPEAT words that are heard but ability to speak SPONTANEOUSLY/COMPREHEND speech of others caused by damage to ARCUATE FASCICULUS
CONDUCTION APHASIA
bundle of axons that connects WERNICKE’S AREA w BROCA’S AREA + carries info abt word sounds
ARCUATE FASCICULUS
How are APHASIC BILINGUALS different from MONOLINGUAL APHASICS?
BILINGUAL APHASICS can display aphasia symptoms in ONE LANG + NOT THE OTHER
variations in rhythm/pitch/cadence that communicate info
