Resource summary

Question 1

Question
What has traditionally been the main reason for the characterization of the left hemisphere as the “dominant” hemisphere?
Answer
  • evidence that the left hemisphere usually processes complex information
  • evidence that the left hemisphere usually processes language
  • the fact that the majority of people are right-handed
  • evidence that patients use only their left hemisphere for processing information after split-brain surgery

Question 2

Question
What is the main function of Wernicke’s area?
Answer
  • speech comprehension
  • speech production
  • sensory integration
  • motor integration

Question 3

Question
If you knew that a surgeon was about to do a surgery to disconnect the cerebral hemispheres, which of the following patients is she most likely to operate on?
Answer
  • a patient in a coma
  • a patient with epilepsy
  • a patient with schizophrenia
  • a patient with antisocial personality disorder

Question 4

Question
Which of the following would be MOST likely to be impaired as a result of damage to the right hemisphere?
Answer
  • language comprehension
  • sensations from the right side of the body
  • vision from the left eye
  • control of the left leg

Question 5

Question
If you present a sound in the right ear, where will that sound be processed first?
Answer
  • right temporal lobe
  • left temporal lobe
  • right parietal lobe
  • left parietal lobe

Question 6

Question
Because the speech centre is generally located in the left hemisphere of the brain, what would a split-brain patient be unable to describe or name?
Answer
  • an object seen in the left visual field
  • an object felt with the right hand
  • an object seen in the right visual field
  • an object presented directly in front of him or her

Question 7

Question
If you sent the word “banana” to the left hemisphere and the word “cucumber” to the right hemisphere in a patient with a severed corpus callosum, which of the following would the patient be able to name verbally?
Answer
  • both items
  • neither item
  • only the banana
  • only the cucumber

Question 8

Question
Imagine that a picture of a spoon is briefly flashed in the left visual field of an individual with a severed corpus callosum. At the same time, a picture of a cup is briefly flashed in the right visual field. What would this individual likely say based on Roger Sperry’s work with splitbrain patients?
Answer
  • “I saw a spoon resting in a cup.”
  • “I saw a cup.”
  • “I saw a spoon.”
  • “I didn’t see anything.”

Question 9

Question
Imagine that a picture of a blue circle is briefly flashed in the left visual field of an individual with a severed corpus callosum. At the same time, a picture of a red square is briefly flashed in the right visual field. What would this individual likely say based on Roger Sperry’s work with splitbrain patients?
Answer
  • “I saw a blue circle.”
  • “I didn’t see anything.”
  • “I saw a red square.”
  • “I saw a blue circle around a red square.”

Question 10

Question
If a right-handed subject whose corpus callosum has been cut were asked to reproduce a drawing, what could we predict?
Answer
  • best performance by the left hand
  • best performance by the right hand
  • equal performance by the two hands
  • an inability to draw with either hand

Question 11

Question
On average, which of the following tasks is performed most quickly by the right hemisphere?
Answer
  • reading and naming items verbally
  • hearing and listening
  • processing visual information from the right visual field
  • locating and recognizing objects or people

Question 12

Question
Chase is using a single earphone to listen in on a conversation. Based on the research that investigated hemispheric specialization in intact brains, what could we suggest in order for Chase to recognize the words he hears most quickly?
Answer
  • put the earphone in his right ear
  • hum lightly to cancel out the background noise
  • close his eyes while he listens to the conversation
  • watch the conversation, in addition to listening

Question 13

Question
What is the left hemisphere’s specialty in both splitbrain people and neurologically intact people?
Answer
  • spatial perception
  • motor initiation
  • visual recognition
  • verbal processing

Question 14

Question
Which of the following is NOT primarily controlled by the left hemisphere of the brain?
Answer
  • visual-spatial abilities

Question 15

Question
Which of the following is LEAST associated with left hemisphere functioning?
Answer
  • reading
  • speaking
  • writing words
  • musical recognition

Question 16

Question
Nadine had a stroke that was confined to the right side of her brain. What sort of task will be most difficult for Nadine, based on hemispheric lateralization studies?
Answer
  • mathematics and logical reasoning skills
  • fine motor coordination, such as for handwriting
  • spatial skills, such as fitting together puzzle pieces
  • language and communication skills

Question 17

Question
Which of the following parts of the brain is most likely to play a major role in the work of artists, architects, and engineers, who must rely heavily on visual-spatial skills?
Answer
  • corpus callosum
  • left hemisphere
  • right hemisphere
  • cerebellum

Question 18

Question
Which of the following is associated with brains that have low levels of lateral specialization?
Answer
