Question 1 of 18

1

What has traditionally been the main reason for the characterization of the left hemisphere as the “dominant”
hemisphere?

Select one of the following:

  • 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

Explanation

  • speech production

  • sensory integration

  • motor integration

Explanation

following patients is she most likely to operate on?

Select one of the following:

  • a patient in a coma

  • a patient with epilepsy

  • a patient with schizophrenia

  • a patient with antisocial personality disorder

Explanation

Question 4 of 18

1

Which of the following would be MOST likely to be impaired as a result of damage to the right hemisphere?

Select one of the following:

  • language comprehension

  • sensations from the right side of the body

Explanation

Question 5 of 18

1

If you present a sound in the right ear, where will that sound be processed first?

Select one of the following:

  • right temporal lobe

  • left temporal lobe

  • right parietal lobe

  • left parietal lobe

Explanation

Question 6 of 18

1

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?

Select one of the following:

  • 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

Explanation

Question 7 of 18

1

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?

Select one of the following:

  • both items

  • neither item

  • only the banana

  • only the cucumber

Explanation

Question 8 of 18

1

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?

Select one of the following:

  • “I saw a spoon resting in a cup.”

  • “I saw a cup.”

  • “I saw a spoon.”

  • “I didn’t see anything.”

Explanation

Question 9 of 18

1

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?

Select one of the following:

  • “I saw a blue circle.”

  • “I didn’t see anything.”

  • “I saw a red square.”

  • “I saw a blue circle around a red square.”

Explanation

Question 10 of 18

1

If a right-handed subject whose corpus callosum has been cut were asked to reproduce a drawing, what could
we predict?

Select one of the following:

  • 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

Explanation

Question 11 of 18

1

On average, which of the following tasks is performed most quickly by the right hemisphere?

Select one of the following:

  • reading and naming items verbally

  • hearing and listening

  • processing visual information from the right visual field

  • locating and recognizing objects or people

Explanation

Question 12 of 18

1

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?

Select one of the following:

  • 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

Explanation
