Write your name and UTEID on both the ScanTron and on THIS test.  Be sure to record the form number on the ScanTron.

 

1.     You are interested in figuring out what part of the brain is “in charge” of detecting sensation in a rat’s tail.  Which of the following would be least invasive, least hurtful, and least painful for the rat, and be most likely to tell you what you want to know?

a.         lesion the rat’s parietal lobe

b.         lesion the rat’s occipital lobe

c.  drill a hole in the rat’s skull and use an electrode to stimulate the parietal lobe

d.  pinch the rat’s tail while doing an fMRI of the rat and look at the rat’s parietal lobe

e.  do an EEG of the rat, focusing on the frontal lobe, while you pinch its tail

 

2.     General systems theory (GST) argues that all disciplines study “entities” in similar ways.  Which of the following questions would NOT be raised if an investigator started to examine the neurotransmitter serotonin?

            a.  Why are we interested in it?

            b.  What is it composed of?

            c.  How is it related to other neurotransmitters like it?

            d.  How do we deal with a divergent example, or one that’s different from the others?

            e.  How does it change (or develop) over time?

 

3.     Is the mind the subjective experience of the brain? This question is at the core of

            a.  the mind-body debate

            b.  the nature-nurture debate

            c.  the evolutionary debate

            d.  the social-personality debate

            e.  the Lincoln-Douglas debate

 

4.     When a person tells a lie, there is a corresponding increase in:

            a.  skin conductance

            b.  body movements

            c.  occipital lobe activity

            d.  shifting eye motions

            e.  voice volume

 

5.     Cortisol is directly related to all of the following EXCEPT:

            a.         release of glucose

            c.   levels of stress

            d.  immune functioning

            e.   headaches

 

6.         Why is it good that REM sleep is typically associated with muscle paralysis?

            a.  Muscle paralysis forces the body to relax so it can achieve a deeper sleep.

            b.  If the body were not paralyzed during REM sleep, it would move as it does in dreams and potentially dangerous movements would happen.

            c.  If the body were not paralyzed during REM sleep, many people would have small epileptic seizures, interrupting sleep cycles.

d.  REM sleep causes the release of curare – a powerful blocker of the neurotransmitter acetylcholine (which is linked to muscle activity); this explains why so many people die in their sleep.

            e.  Muscle paralysis frees up energy so that the brain can produce beta waves, associated with dreaming.

10.  Natasha and Alex were arguing over whose sleep disorder is worse.  The dispute became surprisingly stressful for both people.  Natasha claimed her sleep disorder is worse because she sometimes wakes up suffocating.  Alex claimed his is worse because…Alex fell asleep in the middle of the argument.  Which sleep disorder does each person have?

            a.         Natasha has alexithymia; Alex has prosopagnosia.

            b.   Natasha has insomnia; Alex has sleep apnea.

            c.         Natasha has sleep apnea; Alex has narcolepsy.

            d.   Natasha is a narc; Alex has sleep paralysis.

            e.   Natasha’s biorhythms are disturbed; Alex is an insomniac.

 

11.   Victor was a participant in an experiment in a sleep laboratory.  The researcher wanted to wake Victor up every time he entered REM sleep.  Which of the following would be the best way for the researcher to know that Victor was in REM sleep?

            a.         His brain would emit theta waves because he was deep in sleep.

            b.   His muscle activity would increase because he was having an active dream.

            c.   He would experience the myoclonic jerk because that indicates the start of REM.

            d.   His brain would emit beta waves because it is very active.

            e.         He will always enter REM sleep exactly two hours after falling asleep.

 

12.   What brain area is most involved in the establishment of a phobia?

            a.         amygdala

            b.         adrenal gland

            c.         hypothalamus

            d.   basal ganglia

13.   Latrina is an accountant for a large company.  Because people must turn their taxes in on April 15th every year, she must work long hours from about March 10 until April 15.  She has found that she starts to feel sick every year around April 16.  What is the best explanation for this?

            a.  She experiences an increase in worry because she fears that she may have made some errors in the work she had done.

            b.         As soon as the stressful period is over, her immune system breaks down and she starts to get sick.

            c.   Her immune system was not working well during the period of high stress. As soon as the stress was over, her immune system finally kicked in and her feeling sick is a sign of effective immune function.

            d.         Feeling sick after a stressor is a normal psychosomatic process.  Her “illness” is all in her head.

            e.   The dopamine neurotransmitters in her parietal lobe are fatigued causing a minor breakdown of her amygdala.

 

14.  You step on a tack and it sticks into the big toe on your left foot.  How are you able to feel the pain? Choose the best answer from below.

            a.  Nerves in the big toe on your left foot fire; nothing else is needed.

            b.         Nerves in the big toe of your left foot fire, sending messages to the big toe in your right foot.

            c.   Nerves in the big toe of your left foot fire, setting off a relay of messages that travels through your spinal cord to your parietal lobe.

            d.   Nerves in the big toe of your left foot fire, setting off a relay of messages that travels through your spinal cord to your frontal lobe.

            e.   Nerves in the big toe of your left foot fire, setting off a relay of messages that travels straight to your adrenal glands. The adrenal glands release cortisol, which causes your toe to swell and alerts your parietal lobe to the injury.

 

15.   Neurologist Paul MacLean proposed that our skull holds not one brain, but three.  These three brains, which he named the “triune brain”, are called the reptilian brain, old mammalian brain, and new mammalian brain.  What supports this idea?

            a.         The brain has three separate lobes on each side, and the three lobes each have different specializations but are interconnected.

            b.         Surveying the “three brains” is like an archeological dig through evolutionary history, with each new brain adding new and more complex abilities.

            c.         The brain has three physically separate areas, all joined together by the corpus collosum.

            d.  Freud also discussed the three brains – the id, ego, and superego – which correspond to MacLean’s three brains.

18.  Your friend likes to make bets on horse races.  Recently, he fell off his horse and injured his prefrontal cortex. Since his fall, he has lost more bets than he used to.  Why might this be?  Choose the best answer from the options below.

            a.   The injury to his prefrontal cortex damaged the interaction between his emotions and logic.  Because he no longer experiences anxiety, he can’t decide which are risky (or scary) bets and which ones are not.

            b.         The injury to his prefrontal cortex interferes with the two sides of his brain – the emotional side and the logical side – talking to each other.  He no longer experiences anxiety that gets in the way of his making big bets. 

            c.         The injury to his prefrontal cortex damaged his pleasure center, and now he makes a lot more bets because it just feels good.

            d.   The injury to his prefrontal cortex damaged the interaction between his amygdala and his logic centers. He no longer experiences fear that gets in the way of his making big bets. 

            e.   The injury to his prefrontal cortex interferes with his ability to count money and do basic math, so he bets larger amounts.

            c.         Yes, because organisms can build increasingly complex structures as they grow older

            d.         No, structuralism focuses on how individuals understand conscious experience whereas evolutionary psychology deals with behavioral adaptations to environmental challenges

            e.   Yes, both schools of thought were founded by Charles Darwin

 

25.  Last night Trevor dreamed about being stuck at the bus stop for 2 hours.  He couldn’t get to class, and he missed an exam.  Which of the following is NOT a plausible psychological explanation for the cause of his dream:

      a.         Trevor has been stressed about his upcoming exam, and the dream was a way to organize these fears.

            b.         Information from the temporal lobe and frontal cortex was sending signals to the amygdala which is responsible for emotional dreams.

            c.         There were random nerve impulses firing in Trevor’s brain during the night, and he was trying to make sense of them.

            d.         Because he took a powerful sleeping pill, he didn’t experience any REM sleep – which caused his dream to be far more vivid than usual.

            e.         Trevor had a long wait at the bus stop earlier in the day, and his brain was still processing this experience.

      

26.   As students walked into their Psychology 301 exam, they were asked how much sleep they had gotten the night before.  Later, the teacher correlated the hours of sleep with the students’ grades on the exam.  The correlation (r) between hours sleep and exam performance was most likely:

            a.  +0.80 – a strong relationship suggesting that the more sleep, the better the grades.  The strength of the relationship indicates that sleep quality affects grade performance.

            b.         -1.73 – a very strong negative relationship suggesting that the less sleep that people got, the better their grades.  This is probably because people who studied harder during the night knew more information

            c.         +0.32 – a modest link suggesting that people who sleep longer tend to make better grades or, conversely, people who are more prepared for the exam tend to sleep better the night before. 

            d.         -0.51 – a modest link suggesting some kind of negative emotional relationship between sleeping and test taking.  This statistic suggests that people with negative attitudes towards the exam may also have problems with sleeping.

            e.         -0.03 – an almost perfect link between sleeping and grade performance.  The 3% of people who sleep the most are the ones with the lowest exams.

 

27.  One of the overarching differences between the activation-synthesis theory (AST) and the evolved threat-rehearsal theory (TRT) of dreams is that

            a.         the former emphasizes the emotional strength of dreams, whereas the TRT thinks of dreams as meaningless images.

            b.         the former thinks of dreams as a side effect of other processes, whereas the latter focuses on the function of dreams.

            c.         the AST emphasizes the social nature of dreams, whereas the TRT emphasizes the cognitive aspects of dreams.

            d.         AST deals only with dreams where people are making things (e.g., houses, cookies), whereas the TRT deals with dreams where people are dealing with the destruction of objects.

            e.         AST and TRT are exactly the same theory but were proposed by different researchers at the same time.

 

28.  Research on the subliminal effect of words on later free associations shows that

            a.         people generally know the things that affect their decisions.

            b.         people are often not aware of the things that affect their decisions, but they create reasons why they decided on the choice they did.

            c.         subliminal effects simply don’t exist, unlike what was proposed by Freud

    d.         people usually only remember words about which they have conscious awareness; they tend to forget words linked to unconsciousness
