Question 1

Most left-handers have left-hemisphere dominance for speech

Accepted Answer

Studies have shown that the majority of left-handers have left-hemisphere dominance for speech, which is the same as right-handers. However, there is still a small percentage of left-handers who have right-hemisphere dominance for speech.

Question 2

When heterosexual men were given oxytocin or a placebo prior to meeting an attractive woman,the oxytocin had no effect on single men,but it caused those in a monogamous relationship to stand farther away.​

Accepted Answer

This statement is true. The study found that oxytocin had no effect on single men, but caused monogamous men to stand farther away from an attractive woman.

Question 3

Most people use only one hemisphere for most tasks.​

Accepted Answer

This statement is false. Most tasks involve the activation of both hemispheres of the brain. Different tasks may involve more activation in one hemisphere than the other, but both hemispheres are utilized.

Question 4

The left hemisphere is connected to skin receptors mainly on the ____ half of the body,and controls muscles mainly on the ____ side of the body.​
A)left; right
B)​left; left
C)​right; left
D)right; right

Accepted Answer

The answer of The left hemisphere is connected to skin...

Question 5

When a woman in a persistent vegetative state was told to imagine playing tennis,an fMRI of her brain showed increased activity in motor areas of her cortex,similar to what healthy volunteers showed.​

Accepted Answer

This statement is true. Several studies have shown that imagining movements or actions can activate the same motor areas of the cortex as actually performing those movements or actions. This phenomenon is known as motor imagery or mental simulation. The fact that a woman in a persistent vegetative state was able to show increased activity in motor areas of her cortex when imagining playing tennis is a promising finding for the potential use of motor imagery in rehabilitation and communication with non-responsive patients.

Question 6

The left and right hemispheres exchange information through a set of axons called the corpus callosum.

Accepted Answer

The corpus callosum is a set of axons that connects the left and right hemispheres of the brain, allowing them to exchange information.

Question 7

Language studies with bonobos suggest that they can understand more than they can produce.​

Accepted Answer

Research on language studies with bonobos indicates that they have the ability to understand human language to some extent, but have limited ability to produce or communicate through language themselves. Therefore, the statement is true.

Question 8

In relation to their interests,aptitudes,and skills,people are either predominantly right-hemisphere or left-hemisphere.​

Accepted Answer

This statement is false. The idea of people being predominantly right or left hemisphere dominant is a popular myth. While there are different functions associated with each hemisphere, research has shown that both hemispheres are continuously involved in the majority of cognitive processes. Both sides of the brain work together and communicate with each other to perform complex tasks.

Question 9

The left hemisphere appears to be specialized for language before language develops.​

Accepted Answer

Research shows that the left hemisphere of the brain is specialized for language processing even in infants before they develop language skills. Studies have found that the left hemisphere shows greater activation than the right hemisphere during language tasks, such as speech perception and production, in very young infants as young as a few months old.

Question 10

Normally,a split-brain patient should be able to name an object flashed to the left visual field.​

Accepted Answer

In a split-brain patient, the left visual field is processed by the right hemisphere of the brain which is not specialized for language functions. Therefore, the patient would not be able to name an object flashed in the left visual field. They would be able to point to it with their left hand (controlled by the right hemisphere) or describe its qualities using nonverbal means, but they would not be able to name it.

Question 11

Observations of people with Williams syndrome indicate that language is not simply a by-product of overall intelligence.​

Accepted Answer

Studies have shown that individuals with Williams syndrome often have above-average language abilities despite having below-average IQ scores. This suggests that language and intelligence are separate cognitive domains.

Question 12

Most of the information passing from one hemisphere to the other does so by passing through which structure?​
A)cerebellum
B)​inferior colliculus
C)​corpus callosum
D)massa intermedia

Accepted Answer

The corpus callosum is the main bridge of nerve fibers connecting the two hemispheres of the brain and is responsible for most of the communication and transfer of information between the two hemispheres.

Question 13

The brain has ____ control of the facial muscles.​
A)ipsilateral
B)​contralateral
C)​bilateral
D)mixed

Accepted Answer

The facial muscles receive bilateral control from the brain, meaning that the left and right sides of the face are controlled by both the left and right hemispheres of the brain. This is why damage to one hemisphere of the brain (such as a stroke) may affect only one side of the face.

Question 14

Nearly all current philosophers and neuroscientists reject monism.​

Accepted Answer

Monism is still a debated perspective in both philosophy and neuroscience, with some scholars supporting it and others rejecting it.

Question 15

In most humans,control of language is centered in the ____.​
A)left hemisphere
B)​right hemisphere
C)​corpus callosum
D)cerebellum

Accepted Answer

The left hemisphere is typically associated with language processing in the majority of individuals. Studies have shown that damage to the left hemisphere can result in language deficits, while damage to the right hemisphere typically results in deficits in spatial perception and attention. The corpus callosum is a band of nerve fibers that connects the two hemispheres of the brain and plays a role in communication between them, but it is not specifically responsible for language processing. The cerebellum is primarily involved in motor coordination and balance, not language processing.

Question 16

Wernicke's aphasia is primarily a problem of speech production.​

Accepted Answer

Wernicke's aphasia is primarily a problem of language comprehension and understanding, while speech production may appear fluent but lack meaning or coherence.

Question 17

The left hemisphere of the cerebral cortex is connected to skin receptors and muscles mainly on the right side of the body.​

Accepted Answer

The left hemisphere of the cerebral cortex receives and processes sensory information from and sends motor signals to the right side of the body. Conversely, the right hemisphere is connected to skin receptors and muscles mainly on the left side of the body. This is called contralateral control.

Question 18

the right hemisphere is dominant for recognizing both pleasant and unpleasant emotions in others.​

Accepted Answer

Research has shown that the right hemisphere of the brain plays a larger role in the recognition of emotions, both positive and negative, in others.

Question 19

In most people,the right hemisphere is dominant for speech.

Accepted Answer

In most people, the left hemisphere is dominant for speech.

Question 20

Auditory information is sent to the ____.​
A)ipsilateral hemisphere only
B)​contralateral hemisphere only
C)​ipsilateral and contralateral hemispheres equally
D)contralateral hemisphere more than the ipsilateral hemisphere

Accepted Answer

Auditory information is primarily sent to the contralateral hemisphere, meaning that sounds from the right ear are processed more in the left hemisphere and vice versa, although there is also some ipsilateral processing.
