Questão 1

Questão

Responda
  • 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

Questão 2

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

Questão 3

Responda
  • a patient in a coma
  • a patient with epilepsy
  • a patient with schizophrenia
  • a patient with antisocial personality disorder

Questão 4

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

Questão 5

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

Questão 6

Questão
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?
Responda
  • 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

Questão 7

Questão
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?
Responda
  • both items
  • neither item
  • only the banana
  • only the cucumber

Questão 8

Questão
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?
Responda
  • “I saw a spoon resting in a cup.”
  • “I saw a cup.”
  • “I saw a spoon.”
  • “I didn’t see anything.”

Questão 9

Questão
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?
Responda
  • “I saw a blue circle.”
  • “I didn’t see anything.”
  • “I saw a red square.”
  • “I saw a blue circle around a red square.”

  • processing visual information from the right visual field
  • locating and recognizing objects or people

Questão 12

Questão
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?
Responda
  • put the earphone in his right ear
  • hum lightly to cancel out the background noise
  • close his eyes while he listens to the conversation
