Question 1

Which of the following statements is correct?

Accepted Answer

Generalization and reduction are two important tools used in science. Generalization involves making predictions and drawing conclusions about a larger population based on a smaller sample, while reduction involves breaking down complex systems or phenomena into smaller, more manageable parts for study. Both of these tools are used by scientists to gain a better understanding of the world around us. Option A is incorrect, as reduction involves simplifying complex processes, not the other way around. Option B is incorrect, as the goal of religion is not related to scientific study or prediction. Option D is incorrect, as while reductionistic explanations are sometimes used in science, they are not the only type of explanation used. Option E is also incorrect, as many scientific studies do use human experimental subjects.

Question 2

A person suffering from unilateral neglect would be unable to

Accepted Answer

Unilateral neglect typically affects the ability to attend to one side of space, often the left, which can result in difficulties with tasks like accurately labeling the hours on a clock drawing, as they may neglect one side of the clock.

Question 3

A key function of the right hemisphere relates to the

Accepted Answer

The right hemisphere of the brain primarily controls the motor functions of the left side of the body.

Question 4

Imagine that your corpus callosum has been sectioned to minimize your epileptic seizures. Suppose that your left nostril is plugged with cotton and that a fresh rose has been placed near your right nostril. Under these conditions, the rose would

Accepted Answer

The right nostril sends sensory information to the right hemisphere, which is not responsible for language in most people. With the corpus callosum severed, the information cannot be transferred to the left hemisphere, which is typically responsible for verbal processing, so a verbal report is not generated.

Question 5

________ represent explanations used by all scientists.

Accepted Answer

Generalizations represent explanations used by all scientists.

Question 6

Unilateral neglect involves

Accepted Answer

Unilateral neglect typically involves the inability to notice or attend to objects on the left side, often due to damage to the right hemisphere of the brain, particularly the parietal lobe.

Question 7

The "rubber hand" illusion occurs only when sensory stimulation of a person's hand leads to

Accepted Answer

The answer of The "rubber hand" illusion occurs only when...

Question 8

Which sensory system below transmits information from the left side of the body to the left hemisphere?

Accepted Answer

The olfactory system is unique in that it does not cross over to the opposite hemisphere; the left nostril sends information directly to the left hemisphere.

Question 9

Imagine that your corpus callosum has been sectioned to minimize your epileptic seizures. Suppose that your left nostril is plugged with cotton and that a fresh rose has been placed near your right nostril. Under these conditions, you would be most likely to

Accepted Answer

The right nostril is connected to the right hemisphere, which controls the left hand. With the corpus callosum severed, the right hemisphere cannot communicate with the left hemisphere, which is responsible for speech. Therefore, you would use your left hand to select the flower without being able to verbally report the smell.

Question 10

A scientific explanation of a complex phenomenon that is cast in terms of a simpler one involves the process of

Accepted Answer

The process described involves reducing a complex phenomenon to simpler terms. This is known as reduction, which is the process of simplifying a complex phenomenon to a simpler one. Therefore, the best choice is E) reduction.

Question 11

Ancient Greek culture before Hippocrates considered the ________ to be the seat of thought and emotion.

Accepted Answer

Ancient Greek culture believed that the heart, not the brain, was the seat of thought and emotion. This belief persisted until the time of Hippocrates, who argued that the brain was the source of intelligence and the center of the nervous system.

Question 12

The philosopher ________ attributed thought and emotion to the brain, whereas ________ considered the function of the brain as important for cooling the heart.

Accepted Answer

Hippocrates attributed thought and emotion to the brain, while Aristotle considered its function as important for cooling the heart.

Question 13

The author of the first psychology text was ________ and the text was entitled ________.

Accepted Answer

Wilhelm Wundt is considered the founder of psychology and established the first psychological laboratory in 1879. He published a book entitled Principles of Physiological Psychology in 1874, which is widely considered to be the first true textbook on psychology.

Question 14

Which of the following is true of the cerebral hemispheres?

Accepted Answer

The answer of Which of the following is true of...

Question 15

A person who sustains damage within her right parietal cortex would be expected to

Accepted Answer

The answer of A person who sustains damage within her...

Question 16

Imagine that you now experience such an overly strong fear of dogs that you refuse to leave your house for fear of encountering a dog. A learning theorist would suggest that the roots of your fear can be attributed to past classical conditioning, in which you associated the sight and sound of a dog with some aversive experience. This type of explanation would involve the process of

Accepted Answer

The explanation offered involves the process of generalization, as the fear response has been generalized from the specific dog that was associated with an aversive experience to all dogs. The other choices (rationalization, pseudoscience, reductionism, and dualism) are not relevant to the presented explanation.

Question 17

In most persons, a key function of the left hemisphere

Accepted Answer

The left hemisphere is typically associated with language processing in the majority of individuals. This includes language comprehension, speech production, and other aspects of language use. However, this does not mean that the left hemisphere is solely responsible for language processing, as language abilities may be distributed across both hemispheres in some individuals.

Question 18

You notice that your roommate has difficulty sleeping after consuming heavily caffeinated drinks. You know from your courses that caffeine can stimulate brain neurons that produce arousal (and that such arousal disturbs sleep function). If you suggest to your roommate that his/her insomnia reflects the action of caffeine on brain function, your explanation would involve the process of

Accepted Answer

Reduction involves explaining a complex phenomenon in terms of its simpler, more fundamental components. In this case, the complex phenomenon of insomnia is being explained by the simpler, fundamental action of caffeine on brain function.

Question 19

Your textbook author asserts that the primary function of the brain is to

Accepted Answer

The answer of Your textbook author asserts that the primary...

Question 20

The urge to move your arm in response to a threatening stimulus depends on activation of the

Accepted Answer

The supplemental motor area (SMA) is involved in the planning and initiation of movement. In response to a threatening stimulus, the SMA might activate the motor neurons in the spinal cord that control the muscles responsible for moving the arm away from the threat. The parietal cortex, corpus callosum, and posterior cingulated cortex are not directly involved in movement planning or execution. The primary visual cortex detects visual stimuli but does not initiate movement in response to them.
