Question 1

If a person retains basic physiological function,but has lost cognitive function,the person's condition is called:

Accepted Answer

A persistent vegetative state (PVS) is a condition in which a person has retained basic physiological function, such as breathing and circulation, but has lost higher cognitive function and awareness of their surroundings. The term "differential vegetative state" is not a recognized medical term, "unconsciousness" implies a complete loss of consciousness and physiological function, and "chronic unconscious dementia" is not a specific medical condition.

Question 2

Research has found that the brains of men,when solving rotating figure problems,were especially active in the:

Accepted Answer

The answer of Research has found that the brains of...

Question 3

Why would a split-brain patient say that he saw the word "ART" when "HE•ART" is flashed on the screen in front of him?

Accepted Answer

In a split-brain patient, the corpus callosum, which connects the two hemispheres of the brain, has been severed. As a result, when a word is presented to one visual field (e.g. the left visual field), it is processed in the opposite hemisphere (in this case, the right hemisphere). However, only the left hemisphere has the ability to produce language/speak. Therefore, the patient can only report verbally what they see in their right visual field (processed by the left hemisphere). In this case, "ART" is presented in the right visual field, so it is processed by the left hemisphere and can be verbally reported. "HE•ART" is split between the two visual fields, with "HE" in the left visual field (hence processed by the right hemisphere) and "ART" in the right visual field (hence processed by the left hemisphere). Therefore, the patient can only report verbally what they see in the right visual field, which is "ART".

Question 4

Which part of the brain would "see" a face by analyzing piece-by-piece its many separate parts (e.g.,nose,eye,lips,cheek,etc.)?

Accepted Answer

The left hemisphere of the brain is typically involved in analytical tasks, including the processing of details such as recognizing faces by analyzing their parts separately. This contrasts with the right hemisphere, which is more involved in holistic processing.

Question 5

Recent research indicates that the amygdala processes ____ differently in men and women.

Accepted Answer

Recent research has found that the amygdala processes intense emotional experiences differently in men and women. Specifically, women tend to have stronger and more frequent amygdala responses to negative emotional stimuli, such as fear or anxiety, while men tend to have stronger amygdala responses to positive emotional stimuli, such as reward or excitement.

Question 6

When you see a picture of yourself,you recognize your own face.Which part of the brain is responsible for that ability?

Accepted Answer

The left hemisphere of the brain is responsible for facial recognition and processing.

Question 7

With regard to performance on rotating figure problems:

Accepted Answer

Research has shown that males tend to perform better on spatial tasks, such as mental rotation, being both faster and more accurate than females.

Question 8

Gazzaniga believes that when we do some type of activity,the brain uses:

Accepted Answer

Gazzaniga's research into the modular nature of the brain suggests that when we engage in activities, the brain utilizes multiple different mental programs simultaneously, rather than relying on a single or sequential program approach. This reflects the complexity and parallel processing capabilities of the human brain.

Question 9

Your psychology instructor enjoys using analogies,similes,and metaphors in the class.Today,she is talking about the corpus callosum.As she is lecturing on the corpus callosum,you're thinking of an appropriate metaphor.Which of the following is the most appropriate simile?

Accepted Answer

A bridge is a fitting simile for the corpus callosum because, like a bridge, the corpus callosum connects two separate parts, in this case, the left and right hemispheres of the brain.

Question 10

Harry is attending his 10-year high school reunion.As he visits with his classmates,he has some trouble putting together faces with names.He sees someone he thinks he knows by the shape of the nose and eyes.Which part of the brain is probably allowing Harry to analyze the features of the many faces he sees?

Accepted Answer

The answer of Harry is attending his 10-year high school...

Question 11

An autopsy of Terri Schiavo's brain revealed that:

Accepted Answer

An autopsy revealed that Terri Schiavo's brain was severely atrophied and that no treatment would have helped her to recover.

Question 12

Your class is watching a video of a split-brain operation.You see the surgeon take a scalpel and sever a structure to disconnect the two hemispheres.Your friend asks you what the structure was that was being cut and you say the:

Accepted Answer

The corpus callosum is a large band of neural fibers that connects the left and right hemispheres of the brain. When this structure is severed, it is called a split-brain operation, which results in a disconnection between the two hemispheres. Therefore, this is the most appropriate answer.

Question 13

If Candy is trying to remember a very frightening movie,her ____ would be especially active.

Accepted Answer

The amygdala is involved in processing emotions, especially fear, and the left hemisphere amygdala would be active when recalling a frightening movie.

Question 14

Women tend to be better than men at tasks that measure:

Accepted Answer

Research has shown that women often outperform men in tasks related to perceptual speed, which involves quickly and accurately identifying visual details.

Question 15

A word is flashed before a normal subject so that it is presented to his left visual field.Before the subject can say the word,the:

Accepted Answer

Impulses must cross hemispheres because the left visual field is processed by the right hemisphere of the brain, and language functions are predominantly located in the left hemisphere. Therefore, for the subject to verbalize the word, the information must cross from the right hemisphere to the left hemisphere via the corpus callosum.

Question 16

The right hemisphere of the brain is better at ____ tasks,whereas the left hemisphere is better at ____ tasks.

Accepted Answer

Studies have shown that the right hemisphere of the brain is more involved in nonverbal tasks such as spatial reasoning, facial recognition, and music appreciation, while the left hemisphere is more involved in verbal tasks such as language processing, reading, and writing.

Question 17

The flaw in Samuel George Morton's research on skull size was:

Accepted Answer

Samuel George Morton's research was biased as he selected skulls that matched his own bias, thereby leading to inaccurate conclusions about supposed differences in skull sizes between racial groups.

Question 18

Women tend to be better than men at tasks that require:

Accepted Answer

Research suggests that women tend to have better verbal fluency and language skills compared to men, while men tend to excel in tasks that require spatial ability and rotating mental objects. However, it is important to note that there is significant variability within genders and individual differences should be considered.

Question 19

Brain scans reveal that when women are solving rotating figure problems,their ____ shows maximum activity.

Accepted Answer

Studies have shown that the right parietal-temporal area of the brain is responsible for spatial processing and manipulation. When women are solving rotating figure problems, they activate this area of the brain the most. The other options (B, C, D) are not associated with spatial processing and manipulation.

Question 20

In recalling intense emotional experiences,men show greater activity in the ____ while women show greater activity in the ____.

Accepted Answer

Research has shown that in recalling intense emotional experiences, men tend to show greater activity in the right hemisphere of the amygdala, while women show greater activity in the left hemisphere of the amygdala. This difference suggests a gender-related variation in how emotions are processed and remembered in the brain.
