Electrically stimulating a rat's amygdala would most likely produce which of the following?

Aggression

Which of the following would most likely result from an injury to the medulla?

A life-threatening disruption of heartbeat and breathing

Damage to the cerebellum would most likely result in which of the following problems?

A loss of motor coordination

Areas that have a large prevalence of malaria, such as Africa, have a high frequency of children who have sickle cell anemia or are carriers of the trait. What role does the concept of natural selection play in this trend?

Being a carrier of, or having sickle cell anemia is adaptive in this region, because it protects against malaria. Subsequently, children born with sickle cell anemia are less likely to die from malaria.

Brain damage that leaves a person capable of understanding speech but with an impaired ability to produce speech most likely indicates injury to which of the following?

Broca's area

Which of the follow scenarios is the best example of natural selection?

During a drought, the foliage in a region turns brown. More brownish moths than whitish moths from a particular breed survive predation and produce more offspring. Subsequent generations of moths have a higher percentage of brownish moths than the generation before.

Which of the following is the best evidence that environment plays a role in intelligence?

Identical twins reared together are more similar than identical twins reared apart

The nature-nurture issue is best exemplified by which of the following questions?

Is level of intelligence the result of one's environment and specific learning, or is it a result of biological maturation?

Which of the following is true of the reticular activating system?

It regulates levels of arousal.

Which of the following is brain-imaging technique that produces the most detailed picture of brain structure?

Magnetic resonance imaging (MRI)

If an individual has lost the ability to feel pain in the left arm, there is most likely damage to what area of the brain?

Right parietal lobe

What is the primary function of the brain region indicated by the arrow?(pons)

Sleeping, waking, and dreaming

A person will most likely develop aphasia as a result of damage to which of the following parts of the brain?

Wernicke's area

During a psychology experiment, a researcher uses a probe to lesion the ventromedial nucleus of a rat's hypothalamus. After the procedure the rat most likely will

eat more and gain weight

The brain scans of people with amnesia are most likely to show damage to the

hippocampus

Brain lateralization refers to the

inclination for certain cognitive processes to be specialized to one hemisphere of the brain or the other

People who have experienced severe damage to the frontal lobe of the brain seldom regain their ability to

make and carry out plans

The result of the evolutionary process that preserves traits that enhance the adaptation of an organism and suppresses traits that do not is called

natural Selection

The brain's ability to adapt after it is damaged is known as

plasticity

The right occipital lobe receives visual information from the

right half of both retinas

Damage to a small part of the occipital lobe would most likely result in a

visual deficit
