In considering the relative contributions of genes and environment, most scientists would agree that:
genes and environment interact to determine behavior.
social context has little effect on behavior.
environment plays the more important role in shaping behavior.
only genes shape behavior.
genes and environment interact to determine behavior.
Adoption studies are an important tool of behavioral genetics because they:
allow us to examine the effects of nonrelated mothering.
show that environment overwhelms the effect of genes.
allow us to look at the contributions of environment and genetics on behavior.
are so rare.
allow us to look at the contributions of environment and genetics on behavior.

different genes and different environments.
Heritability refers to:
the degree to which genes control a characteristic.
an estimate of how much of the variation in a characteristic is due to known genetic variation.
the degree to which shared environments account for a shared characteristic among siblings.
the degree to which a mother’s characteristics are passed on versus a father’s characteristics.
an estimate of how much of the variation in a characteristic is due to known genetic variation.
What does the brain have to do with psychology?
All options are correct.
The brain is responsible for all our thinking.
The brain allows all of our behavior.
The brain lets us feel all our emotions
All options are correct.
Luck is a quarterback on a football team. He throws the ball into the air and the wide receiver catches it and scores a touchdown. In the neuron, which physical part plays a role similar to that of the wide receiver in football?
dendrite
synapse
myelin
axon
dendrite
dendrite -> receive information from other neurons
Mary is a scientist investigating neurons. She knows that during the transmission phase, when a postsynaptic neuron experiences enough stimulation it will
receive inhibitory neurotransmitters.
fire an action potential.
stay in a resting state.
receive excitatory neurotransmitters
fire an action potential.
Dante’s life is in danger because he has damage to a part of his hindbrain that regulates breathing, blood pressure, and heart rate. Dante most likely has damage to his _____.
cerebellum
amygdala
brain stem
substantia nigra
brain stem
An extension of the spinal cord; it houses structures that control functions associated with survival, such as heart rate, breathing, swallowing, vomiting, urination, and orgasm.
Lupe is at a party with her friends late on Saturday night and is experiencing a lot of thoughts and feelings. Which of the following messages would NOT come from Lupe’s hypothalamus?
“I want to have sex!”
“I am so happy!”
“I need to go to sleep!”
“I feel hungry!”
“I am so happy!”
hypothalamus -> A brain structure that is involved in the regulation of bodily functions, including body temperature, body rhythms, blood pressure, and blood glucose levels; it also influences our basic motivated behaviors.
After a surgery goes terribly wrong, Chris is not able to form new memories. Chris most likely has damage to a structure in his forebrain called the ______.
basal ganglia
thalamus
hippocampus
cerebellum
hippocampus
Hippocampus is a complex brain structure embedded deep into temporal lobe. It has a major role in learning and memory.
Stephen was born with a hearing deficit, but there is nothing wrong with his ears. The doctors conclude that there must be damage to Stephen’s ______ lobes.
occipital
temporal
frontal
parietal
temporal
The temporal lobe is one of the four major lobes of the cortex. It is primarily responsible for interpreting sounds from the ears and plays a significant role in recognizing and using language. The temporal lobe also helps with object recognition and interacts with other structures to create new and long term memories
Virginia feels a mosquito land on her left arm. She uses her right hand to brush the mosquito away. The feel of the mosquito is processed by her ______ cortex and the action by her hand is processed by her ______ cortex.
right motor; left somatosensory
left somatosensory; right motor
left motor; right somatosensory
right somatosensory; left motor
right somatosensory; left motor
the right primary somatosensory cortex -> processes sensory information from the left side of the body and vice versa
the left motor -> controls muscles on the right side
Standing in line outside the movie theater, John heard music coming out of someone’s iPod. Because he liked the music, he began to move to the beat. John’s ability to move his body to dance is due to the function of his _____ nervous system.
sympathetic
somatic
autonomic
parasympathetic
somatic
The somatic nervous system -> component of the peripheral nervous system associated with the voluntary control of the body movements via the use of skeletal muscles.
While walking in the woods, Amy sees a bear. The sympathetic branch of her autonomic nervous system activates.
The most likely result is that she
remains calm and tries to conserve her body’s energy.
stops receiving information from her sensory systems.
behaves instinctively so her spinal cord takes control of running away.
begins to sweat and her heartbeat quickens.
begins to sweat and her heartbeat quickens.
The sympathetic branch -> responding to dangerous or stressful situations. In these situations, your sympathetic nervous system activates to speed up your heart rate, deliver more blood to areas of your body that need more oxygen or other responses to help your get out of danger.
A doctor takes Felipe’s blood pressure and it is very high. The doctor says, “You could not have known this without taking a blood pressure test, because you can’t have awareness of your blood pressure.” Felipe’s doctor is saying that _____.

we are conscious of our blood pressure
we must be in an altered state of consciousness to be aware of our blood pressure
our blood pressure affects us through subliminal perception
we are unconscious of our blood pressure
Which of the following is most likely to result from flashing a Coke bottle on a movie theater screen too briefly for a viewer to notice?

There is going to be no effect, because the viewer is unaware of the event.
There will be faster recognition of related words only if the viewer is in an altered state.
With repeated exposure, the viewer will drink more Coke.
The viewer may recognize related words (e.g., soda) more quickly on an immediate test.
