-Guarantee passing score -26 Questions and Answers -format set of multiple-choice -Expert-Verified Explanation Question 1: A transient shortage of oxygen (global ischemia) releases excess glutamate into the extracellular fluid of the brain. This causes neuronal death by hyperexcitation to a greater extent in the hippocampus than in the cortex. Which reason best explains why the hippocampus is selectively vulnerable during global ischemia?

• The magnitude of action potentials is greater in hippocampal than cortical neurons.
• The expression of NMDA receptors is more abundant in hippocampal than cortical

neurons.

• Hippocampal neurons generate a more negative postsynaptic potential than cortical

neurons.

• Hippocampal synapses have faster neurotransmitter diffusion rates compared to

cortical synapses.

Answer:

• The expression of NMDA receptors is more abundant in hippocampal than cortical neurons.

Question 2: role strain

Answer:

The anxiety produced by being unable to meet all role requirements at the same time.

Question 3: Public health campaigns often target behaviors that are formed in adolescence. For example, alcohol, tobacco, and drug use interventions are often designed to prevent or delay risky behaviors because patterns established in adolescence are associated with disorders in adulthood. This example is best described as using which approach to health?

• The biopsychosocial model of health risks
• A macrosociological perspective on health risks
• The social construction of health behavior
• A life course perspective on health behavior

Answer:

• A life course perspective on health behavior

Question 4: EEG

Answer:

An amplified recording of the waves of electrical activity that sweep across the brain's surface. These waves are measured by electrodes placed on the scalp.Question 5: The phenomenon that occurs when people mistakenly read the letter "C" as the letter "O" illustrates which Gestalt principle of perceptual grouping?

• Similarity
• Closure
• Proximity
• Symmetry

Answer:

• Closure

The answer to this question is B because closure, which refers to one of the Gestalt principles of perceptual grouping, occurs when people perceive objects that are incomplete as complete.Question 6: Pairs of research participants interacted for 10 min. They rated themselves and their partners on personality traits and then rated the accuracy of their partners' ratings of them. The partners' ratings were rated as more accurate if they were close to participants' own

self-ratings. This finding illustrates:

• the self-fulfilling prophecy.

• self-verification.
• the self-serving bias.
• self-efficacy.

Answer:

• self-verification.

The answer to this question is B because self-verification refers to the tendency to seek out (and agree with) information that is consistent with one's self-concept.

Question 7: role conflict

Answer:

conflict among the roles connected to two or more statuses

Question 8: CT scan

Answer:

a series of x-ray photographs taken from different angles and combined by computer into a composite representation of a slice through the body

Question 9: Urine from inbred strain (Strain

• male mice was swabbed every day for one week on the nostrils of female mice of inbred

strain (Strain B). Compared to unswabbed, female Strain B mice, uterine weight, but not total body weight, increased in the swabbed mice. Strain A male urine had no effect on uterine weight or body weight of inbred, female Strain C mice. Which statement best explains these results?

• Conserved evolution of pheromones preserves the ability of male mice to elicit

pheromone-mediated behaviors in female mice.

• The molecular profile of puberty-accelerating, chemosensory neurons differs between mouse

strains.

• Pheromone-mediated stimulation causes accelerated female reproductive development in

Strain C mice compared to Strain B mice.

• Genetic variation between Strain A male mice resulted in inconsistent pheromone

concentration in the urine applied to the female groups of mice.

Answer:

• The molecular profile of puberty-accelerating, chemosensory neurons differs between mouse strains.

The answer to this question is B because there was most likely a difference in the receptiveness of the two inbred strains of mice, as the same signal applied to two separate strains produced opposing results. The pheromone would be detected by chemosensory neurons.

Question 10: this type of memory system stores personally experienced episodes with tags for context and time

Answer:

episodic memory system

Question 11: PET

Answer:

a visual display of brain activity that detects where a radioactive form of glucose goes while the brain performs a given task. Able to detect which areas of the brainier active Question 12: A 45-year-old man presents himself at a hospital emergency room. Symptoms include a pounding heart, chest pain, shortness of breath, sweating, and feeling dizzy. Medical tests reveal that the man did not have a heart attack. Which psychiatric diagnosis provides the most likely explanation for the man's symptoms?

• Generalized anxiety disorder
• Panic disorder
• Illness anxiety disorder
• Somatic symptom disorder

Answer:

• Panic disorder

Question 13: When an individual moves from one social class to another over the course of his

or her lifetime, this process is defined as:

• intergenerational mobility.
• intragenerational mobility.
• structural mobility.
• horizontal mobility.

Answer:

• intragenerational mobility.

The answer to this question is B because moving from one social class to another over the course of a lifetime is referred to as intragenerational mobility
