Question 1

If a split-brain subject were given a key (hidden from sight) to feel with his left hand, he
A)could easily name what he had touched.
B)would be unable to describe the object.
C)would be able to point to the key with his right hand.
D)would have to wait for the information transfer to take place before describing it.

Accepted Answer

The left hand is controlled by the right hemisphere of the brain, which lacks the language centers necessary for verbal communication. Therefore, the split-brain subject would be unable to verbally describe the object they are feeling with their left hand.

Question 2

In 1981, _____ won a Nobel Prize for his discovery that the right and left brain hemispheres perform differently on tests of language, perception, music, and other capacities.
A)Richard J.Haier
B)Roger Sperry
C)Bryan Kolb
D)Peter Hepper

Accepted Answer

Roger Sperry won the Nobel Prize in 1981 for his pioneering research on brain lateralization, which demonstrated how the left and right hemispheres of the brain perform different functions related to language, perception, and other cognitive abilities.

Question 3

In most people, the left hemisphere of the brain is in charge of
A)language.
B)art.
C)pattern recognition.
D)music.

Accepted Answer

The left hemisphere is typically associated with language functions, such as speech production and comprehension, as well as reading and writing abilities.

Question 4

After a "split-brain" operation, most people
A)show severe impairment of language ability.
B)show constant competition between the two hemispheres.
C)function relatively normally, unless submitted to specialized testing.
D)show a change in hand dominance.

Accepted Answer

After a "split-brain" operation, the person will function relatively normally in their daily life, unless submitted to specialized testing. This is because the brain is highly capable of compensating for the loss of communication between the two hemispheres. While there may be some changes in hand dominance, language ability, and competition between the hemispheres, these effects are typically not severe enough to significantly impact daily functioning.

Question 5

The right hemisphere is especially adapted for handling perceptual skills, such as drawing a picture or recognizing melodies, while the left hemisphere is especially adapted for the production and understanding of speech.This is known as
A)everyone's split personality.
B)spatial lateralization.
C)hemispheric specialization.
D)peripheral localization.

Accepted Answer

The given statement describes hemispheric specialization, which is the idea that each hemisphere of the brain has unique functions and is adapted for specific types of information processing. This concept is well-supported by research, and understanding hemispheric specialization is important for understanding how the brain processes information and how different cognitive processes are related to different neural regions.

Question 6

In most people, the right hemisphere of the brain is in charge of
A)language.
B)logic.
C)art.
D)mathematics.

Accepted Answer

The right hemisphere of the brain is often associated with creativity and artistic abilities, such as visual-spatial skills, recognizing faces, and understanding music. While there is some overlap in brain functions between the hemispheres, in most people the left hemisphere is associated with language and logic, and the right hemisphere is associated with creativity and intuition. Therefore, the best choice is C) art.

Question 7

The _____ is superior at language, computational math, and analytic thought.
A)right hemisphere
B)left hemisphere
C)midbrain
D)limbic system

Accepted Answer

The left hemisphere of the brain is commonly associated with language processing, logical reasoning, and analytical thought. Therefore, it is superior at language, computational math, and analytic thought.

Question 8

The surgical procedure of cutting the corpus callosum is done in cases of
A)communication problems.
B)severe epilepsy.
C)injury or stroke.
D)split personality.

Accepted Answer

The surgical procedure of cutting the corpus callosum is done in cases of severe epilepsy. This procedure, known as a corpus callosotomy, can help reduce or eliminate seizures that cannot be controlled with medication. It is not done for communication problems or split personality, and injury or stroke may require different surgical interventions.

Question 9

In order to perform a split-brain operation, the _____ must be severed.
A)pons
B)cerebellum
C)corpus callosum
D)cerebral cortex

Accepted Answer

Split-brain operation involves severing the corpus callosum which is a large band of fibers connecting the two hemispheres of the brain. This is done in order to reduce epileptic seizures that may originate from the abnormal communication between the right and left hemispheres.

Question 10

The right hemisphere in humans
A)is the major or dominant one in most right-handed persons.
B)controls psychomotor activity on the right side of the body.
C)governs the ability to use language, do math, and engage in analytical acts.
D)is involved in understanding jokes and in the expression of emotion.

Accepted Answer

The right hemisphere is known to be involved in understanding jokes and in the expression of emotion. A, B, and C are incorrect as the left hemisphere is the dominant one in most right-handed individuals and controls the psychomotor activity on the right side of the body, as well as governing the ability to use language, do math, and engage in analytical acts.

Question 11

A patient who has suffered brain damage to the left hemisphere is likely to experience diminished capacity for
A)naming objects.
B)recognizing faces.
C)composing melodies.
D)expressing emotions.

Accepted Answer

Damage to the left hemisphere of the brain is more likely to result in difficulties with language processing, including naming objects. Recognition of faces is primarily controlled by the right hemisphere, composing melodies involves both hemispheres, and expressing emotions is primarily controlled by the limbic system.

Question 12

We flash a picture of a tree to the right brain of a split-brain patient and a picture of a dog to his left brain.If we ask the split-brain patient to draw what he saw using his left hand (out of sight), he will
A)draw a dog.
B)draw a tree.
C)draw both a dog and a tree.
D)be unable to draw either picture.

Accepted Answer

The right brain is responsible for processing visual information from the left visual field, which includes the image of the tree. The left brain is responsible for processing visual information from the right visual field, which includes the image of the dog. When the patient is asked to draw what they saw using their left hand (controlled by the right brain), they will draw what their right brain saw- in this case, the tree.

Question 13

For most people, an injury to the _____ would result in impairment of speaking, reading, or writing abilities.
A)right cerebral hemisphere
B)cerebellum
C)limbic system
D)left cerebral hemisphere

Accepted Answer

The left cerebral hemisphere is typically responsible for language abilities in most individuals. Injury to this region can result in impairment of speaking, reading, or writing abilities, a condition known as aphasia.

Question 14

Velishea has severe epileptic seizures that cannot be controlled by medication.Therefore, her doctor suggests that a surgery might help.The surgery would involve
A)cutting the corpus callosum.
B)removing the hippocampus.
C)stimulating the brain's pleasure centers.
D)severing the connection between the prefrontal lobe and the hypothalamus.

Accepted Answer

Cutting the corpus callosum is a surgical procedure known as corpus callosotomy, which is sometimes used to treat severe epilepsy that cannot be controlled with medication. This surgery reduces the severity of seizures by preventing the spread of seizure activity between the two hemispheres of the brain.

Question 15

Judging time and rhythm and coordinating the order of complex movements, such as those needed for speech, are special skills of the
A)right hemisphere.
B)left hemisphere.
C)corpus callosum.
D)limbic system.

Accepted Answer

Judging time and rhythm and coordinating complex movements, such as speech, are functions typically associated with the left hemisphere of the brain, which is responsible for language and motor control. The right hemisphere is more involved in spatial reasoning and visual processing. The corpus callosum is a bundle of fibers that connects the two hemispheres and allows for communication between them. The limbic system is involved in emotion, motivation, and memory.

Question 16

An important outcome of Sperry's split-brain experiments was
A)an understanding of hemispheric specialization.
B)a procedure for treating schizophrenia.
C)insight into the relationships between the central and peripheral nervous systems.
D)a technique for training enhanced creativity.

Accepted Answer

Sperry's split-brain experiments provided evidence for hemispheric specialization, showing that the left and right hemispheres of the brain have different functions and abilities.

Question 17

Harriet has lost the ability to recognize faces, and she's also lost her sense of humor.You would expect to find damage to her
A)right hemisphere.
B)left hemisphere.
C)frontal cortex.
D)motor cortex.

Accepted Answer

The right hemisphere of the brain is primarily responsible for facial recognition and processing emotions, including humor. Damage to this area can lead to difficulties in these functions.

Question 18

Successfully negotiating a maze, sculpting pottery, or painting a watercolor is a function of the
A)corpus callosum.
B)left hemisphere.
C)right hemisphere.
D)temporal lobe.

Accepted Answer

Navigating a physical maze or creating art both heavily involve spatial awareness, which is predominantly processed in the right hemisphere of the brain. The corpus callosum helps to facilitate communication between the two hemispheres, but it is not primarily responsible for spatial processing. The left hemisphere is associated with language and analytical thinking, while the temporal lobe is primarily responsible for processing auditory information.

Question 19

The _____ is superior at perceptual skills and detecting and expressing emotions.
A)right hemisphere
B)left hemisphere
C)midbrain
D)corpus callosum

Accepted Answer

Research shows that the right hemisphere of the brain is dominant in processing emotional information and controlling emotional expressions compared to the left hemisphere. This is supported by studies of individuals with damage to specific brain regions, as well as neuroimaging studies showing increased activity in the right hemisphere when processing emotional stimuli.

Question 20

Which of the following is the most likely consequence of a split-brain operation?
A)a patient whose actions are in continual conflict
B)a patient with sharply diminished intellectual capacity
C)a patient who acts normally in most situations
D)a patient with a schizophrenic personality

Accepted Answer

Split-brain operations involve severing the corpus callosum, which is the major pathway connecting the two hemispheres of the brain. As a result, the two hemispheres cannot communicate or share information as effectively. However, this typically only affects certain functions such as language and spatial processing, and patients can still generally act normally in most situations. Options A, B, and D are unlikely consequences of a split-brain operation.
