FRQ: Charlotte is 88 years old and is feeling the effects of her long life. She suffered a stroke five years ago, which left the right side of her body limp. She also sometimes has trouble understanding when she is asked questions. Her doctors believe that she also may be suffering from the beginning stages of Alzheimer's disease. Explain how each might contribute to Charlotte's current circumstance. -Motor cortex -Acetylcholine -Association areas -Plasticity -Epigenetics

1 point: Because Charlotte's right side is limp, the damage from her stroke most likely occurred in the left hemisphere and potentially in her left motor cortex, which would leave her with little muscular control over the right side of her body. Page 110 1 point: If Charlotte suffers from Alzheimer's disease, it is possible that the neurons responsible for producing acetylcholine have deteriorated. Page 87 1 point: If Charlotte's association areas have been damaged, it may be difficult for her to integrate new ideas. She may also have trouble retrieving memories that were once easily recalled. Page 114 1 point: Because of Charlotte's age, her brain will not have the ability to build an abundance of new neural networks, and if she has not recovered from her injury in a few months' time, she is likely to make little progress in her recovery. Page 116 1 point: Perhaps Charlotte has a predisposition for Alzheimer's disease. If she was in an environment that was not enriching and cognitively engaging, it may have made Alzheimer's disease more likely. On the other hand, despite having a genetic predisposition for Alzheimer's disease, if Charlotte was exposed to an enriching environment, her disposition may not have been expressed. Page 137

FRQ: Provide two examples of how nature and nurture interact to affect an individual's physical health.

1 point: Because nature refers to the contributions of heredity, a person may be predisposed to develop (or not) diabetes or heart disease. Page 129 1 point: Because nurture refers to the contributions of environment and the way individuals are raised, an individual may eat a balanced diet and exercise regularly, activities that will make them healthy, which may counteract their heredity. Page 129

FRQ: Karl's doctor is concerned about a loss of neural functioning in Karl's brain. Explain how loss of each of the following might make Karl's reaction time slower. Myelin sheath Acetylcholine (ACh)

1 point: Damage to the myelin sheath would slow down neural impulses and cause the message to travel slower which makes the muscles move slower. Page 82 1 point: ACh is the neurotransmitter involved in muscle action. The doctor might look to see if Karl was producing enough of this neurotransmitter. Page 87

FRQ: Explain how evolutionary psychologists and the concept of social scripts would explain differences in mate selection by men.

1 point: Evolutionary psychologist would argue that men, in general, choose mates who are younger than they are and are able to have many children. Page 146 1 point: Social scripts would explain that the choice of one's mate can be determined by cultural scripts and that child bearing may not be the determining factor. Page 146

FRQ: Brain lateralization means that each hemisphere has its own functions. Give an example of both a left hemisphere and a right hemisphere function. Then explain how the two hemispheres communicate with one another.

1 point: Left hemisphere functions include language, math, and logic. Page 123 1 point: Right hemisphere functions include spatial relationships, facial recognition, and patterns. Page 123 1 point: The corpus callosum carries information back and forth between the two hemispheres. Page 120

FRQ: Doctors sometimes have to remove a portion of the brain to control life-threatening seizures. Describe what the results of the removal of a portion of the somatosensory cortex would be and explain how this procedure might be affected by brain plasticity.

1 point: Removing part of the somatosensory cortex would result in a lack of sensation/inability to feel being touched in the parts of the body associated with the removed tissue. Page 113 1 point: Because of brain plasticity, the person's brain may be able to change and reorganize new pathways based on experience. This is more likely if the person is a child. Page 116

FRQ: While walking barefoot, you step on a piece of glass. Before you have a chance to consciously process what has happened, you draw your foot away from the glass. Identify and explain the three types of neurons that deal with information regarding this painful stimulus.

1 point: Sensory neurons carry information from the point of the injury to the central nervous system. Page 92 1 point: Interneurons are neurons within the brain and spinal cord. Interneurons would help you interpret the pain and enable your spinal cord to send out marching orders. Page 92 1 point: Motor neurons carry the instruction from the central nervous system to activate the muscles in your leg and foot. Page 92

FRQ: Thomas fell and hit his head, so his parents brought him to the emergency room. Explain how the following scans would give doctors different information about the type of injury Thomas may have. CT scan MRI fMRI

1 point: The CT scan would reveal brain damage to structures that would be visible on an X-ray. Page 99 1 point: The MRI would provide a much more detailed picture of the brain than a CT scan. Page 99 1 point: The fMRI would enable the doctors to determine if the functioning of parts of the brain had been damaged, by looking at blood flow to certain regions. Page 100

In what brain region would damage be most likely to 1)disrupt your ability to jump rope 2) disrupt your ability to hear 3) leave you in a coma 4) cut off the very breath and heartbeat of life

1) cerebellum 2) thalamus 3) reticular formation 4) medulla

What are the three key structures of the limbic system, and what functions do they serve?

1) the amygdala is involved in aggression and fear responses. 2) the hypothalamus is involved in bodily maintenance, pleasurable rewards, and control of the hormonal systems. 3) the hippocampus processes memory of facts and events.

Try moving your right hand in a circular motion, as if cleaning a table. Then start your right foot doing the same motion, synchronized with your hand. Now reverse the right foot's motion, but not the hand's. Finally, try moving the left foot opposite to the right hand. Why is reversing the right foot's motion so hard? Why is it easier to move the left foot opposite to the right hand?

1. The right limbs' opposed activities interfere with each other because both are controlled by the same (left) side of your brain. 2. Opposite sides of your brain control your left and right limbs, so the reversed motion causes less interference.

hypothalamous

A neural structure lying below the thalamus, it directs several maintenance activities (eating, drinking, body temperature) helps govern the endocrine system via the pituitary gland, and is linked to emotion and reward.

Limbic system

How are Belyaev and Trut's fox-breeding practices similar to, and how do they differ from, the way natural selection normally occurs?

Over multiple generations, Belyaev and Trut selected and bred foxes that exhibited a trait they desired: tameness. This process is similar to naturally occurring selection, but it differs in that natural selection is much slower, and normally favors traits (including those arising from mutations) that contribute to reproduction and survival.

She is particularly interested in which part of the brain is active when those who are prejudice view photographs of White and Black people. The _______ would be the best neuroimaging technique for Dr. Fiero to use.

PET

How do researchers use twin and adoption studies to learn about psychological principles?

Researchers use twin and adoption studies to understand how much variation among individuals is due to genetic makeup and how much is due to environmental factors. Some studies compare the traits and behaviors of identical twins (same genes) and fraternal twins (different genes, as in any two siblings). They also compare adopted children with their adoptive and biological parents. Some studies compare traits and behaviors of twins raised together or separately.

What bodily changes does your ANS direct before and after you give an important speech?

Responding to this challenge, your ANS (autonomic nervous system) sympathetic division will arouse you. It accelerates your heartbeat, raises your blood pressure and blood sugar, slows your digestion, adn cools you with perspiration. After you give the speech your ANS parasympathetic division will reverse these effects. (returns you to homeostasis)

How does the biopsychosocial approach explain our individual development?

The biopsychosocial approach considers all the factors that influence our individual development: biological factors (including evolution and our genes, hormones, and brain), psychological factors (including our experiences, beliefs, feelings, and expectations), and social-cultural factors (including parental and peer influences, cultural individualism or collectivism, and gender norms).

Hailey is babysitting your 2-year-old nephew for the first time. While her back is turned, he touches his index finger to the pan she just took out of the oven. He pulls his finger away quickly, and a few seconds later begins to scream. Why does it take longer for him to scream than to pull away his finger?

The hand-withdrawal reflex involves only the spinal cord, so it takes time before the information about pain reaches the brain.

What are the mind's two tracks, and what is dual processing?

The human brain has separate conscious and unconscious tracks that process information simultaneously. In vision, for example, the visual action track normally guides our conscious visual processing, while the visual perception track normally operates unconsciously, enabling our quick recognition of objects.

Temporal lobes

The portion of the cerebral cortex lying roughyl above the ears; includes the auditory areas, each of which revieves aditory info primarily from the opposite end.

What do phrenology and biological psychology have in common?

They share a focus on the links between the brain and behavior. Phrenology faded because it had no scientific basis - skull bumps don't reveal mental traits and abilities.

How does information flow through your nervous system as you pick up a fork? Can you summarize this process?

Your central nervous system's hungry brain activates and guides the muscles of your arm and hand via your peripheral nervous system's motor neurons. As you pick up the fork, your brain processes the information from your sensory nervous system, enabling it to continue to guide the fork to your mouth. The functional circle start with sensory input, continues with interneuron processing by the central nervous system, and finishes with motor output.
