Test 15 Page 1 of 5 Test 15 1. In most right-handed people, the Sylvian fissure in the left hemisphere is longer and runs at a shallower angle than the fissure in the right hemisphere. A) True B) False 2. When reading written text aloud, the visual signals are passed to the angular gyrus at the junction of the ___________, _________and ___________ lobes. 3. A gene critical for normal human language has recently been discovered called FOXP2. What are the known differences between the human version of this gene and the corresponding gene in other primates? Choose the correct option. A) Other primates do not possess this gene B) Two amino acids C) The gene is present in only a small subset of chimpanzees D) The gene is identical in humans and other primates 4. How is the Wada procedure used to demonstrate hemispheric lateralization for speech? Choose the correct option. A) Broca's area is anesthetized to see the impact on speech B) Wernicke's area is anesthetized to see the impact on speech C) Each hemisphere is anesthetized in turn to see the impact on speech D) Both Broca's area and Wernicke's area are anesthetized to see the impact on speech 5. What did Michael Gazzaniga and colleagues reveal about hemispheric dominance for language in his studies of humans in whom the corpus callosum had been severed? Choose the correct option. A) If a split-brain person sees a word in the left visual field, he says he sees nothing B) If a split-brain person sees a word in the right visual field, he says he sees nothing C) The left hemisphere can read words but the right hemisphere is necessary to speak the words D) The right hemisphere knows nothing about language 6. Where is the language area known as Wernicke's area located? Choose the correct option. A) Left frontal cortex near the primary motor area B) Left superior temporal lobe between the auditory cortex and the angular gyrus C) In the parietal occipital junction of the left hemisphere near the end of the Sylvian fissure D) In the left precentral gyrus

Test 15 Page 2 of 5 Question 7: How is it possible for a split-brain person to speak intelligibly if the left hemisphere controls speech? Isn’t this inconsistent with the fact that the left hemisphere must direct motor cortex in both hemispheres to coordinate movements of the mouth? Question 8: What can you conclude about the normal function of Broca’s area from the
