BIOL4100: LANGUAGE EXAM QUESTIONS AND ANSWERS WITH
COMPLETE SOLUTIONS VERIFIED
Key Components of the Language System
Broca's area, Wernicke's area, motor cortex, auditory cortex, and angular gyrus
Broca's Aphasia
Paraphasic errors, impaired repetition, nonfluent speech, agrammatical, anomia, but
good comprehension
Paraphasic Errors
Substitution of incorrect words or sounds
Agrammatical
Deficit in construction of proper sentence grammar
Anomia
Word finding deficit
Broca's Aphasia Cause
Damage to association motor cortex in frontal lobe
Wernicke's Aphasia
Paraphasic errors, impaired repetition fluent, grammatical, meaningless speech, and
poor comprehension
Wernicke's Aphasia Cause
Damage to the posterior temporal lobe
Wernicke-Geschwind Model
, Arcuate fasciculus and sensory and motor regions involved in receiving and producing
language
Repeating a Spoken Word According to Wernicke-Geschwind Model
Auditory cortex, Wernicke's area, arcuate fasciculus, Broca's area, or motor cortex
Problems with the Wernicke-Geschwind Model
Reading words does not require activation of auditory response areas, aphasia is
affected by damage to subcortical regions including the thalamus and caudate nucleus,
recovery following stroke suggests other cortical areas may compensate, and most
aphasias include both comprehension and speech deficits
Modern Day Model of Written Word
Early visual processing -> visual word recognition -> semantic association -> promoter
coding -> motor control of speech
Modern Day Model of Spoken Word
Early auditory processing -> auditory word recognition -> semantic association ->
promoter coding -> motor control of speech
Early Visual Processing Location
Striate cortex
Visual Word Recognition Location
Extrastriate cortex
Early Auditory Processing Location
Primary auditory cortex
Auditory Word Recognition Location
Temporoparietal cortex and anterior superior cortex
