Exam 4 Psychology
1. During conception, the 23 unpaired chromosomes in the ovum and sperm combine to form 23 pairs in an entirely new cell called the?
- A. Embryo
- B. DNA
- C. Fetus
- D. Zygote
Correct answer: D
Rationale: The correct answer is D, Zygote. A zygote is formed when the 23 chromosomes from the ovum and sperm combine during conception. It is the initial cell formed and marks the beginning of a new organism. Choice A, Embryo, is incorrect as an embryo is formed later in the development process. Choice B, DNA, is incorrect as DNA is the genetic material within the chromosomes but is not the name of the new cell formed after fertilization. Choice C, Fetus, is incorrect as a fetus is the stage of prenatal development that occurs well after the zygote stage.
2. What are protective factors? Give an example of one and explain how it can impact a person's later functioning.
- A. Protective factors are influences that modify a person's response to environmental stressors, making adverse consequences less likely.
- B. An example of a protective factor is having a warm and caring parent, which may lead to resilience.
- C. Protective factors usually lead to resilience, the ability to adapt successfully to stressful circumstances.
- D. Protective factors always prevent the development of psychopathology.
Correct answer: B
Rationale: Protective factors are influences that modify a person's response to environmental stressors, reducing the likelihood of adverse outcomes. An example of a protective factor is having a warm and caring parent, which can foster resilience in individuals. Resilience allows individuals to adapt successfully to stressful situations. Choice A is incorrect as protective factors do not always prevent adverse consequences but reduce their likelihood. Choice C is incorrect as resilience is the outcome of protective factors, not the other way around. Choice D is incorrect as while protective factors can reduce the risk of psychopathology, they do not always prevent its development.
3. In __, the individual can't recall everything about a certain period of time.
- A. Systematized amnesia
- B. Selective amnesia
- C. Collective amnesia
- D. Localized amnesia
Correct answer: D
Rationale: Localized amnesia refers to the inability to recall all events during a specific period of time. This type of amnesia is characterized by the loss of memories related to a particular incident or period, while other memories remain intact. Choices A, B, and C are incorrect because they refer to different types of amnesia. Systematized amnesia is a term used to describe a selective loss of memory related to a specific category of information or knowledge. Selective amnesia involves the conscious or unconscious blocking out of specific memories, often due to psychological reasons. Collective amnesia pertains to a lack of shared memory or historical awareness within a group or society.
4. Latresha is not hungry, is extremely tired, and doesn't feel like doing much of anything. She often feels that life is just hopeless. These symptoms have been going on for 2 months now. She probably is suffering from which mood disorder?
- A. Generalized anxiety disorder
- B. Bipolar disorder
- C. Major depressive disorder
- D. Obsessive-compulsive disorder
Correct answer: C
Rationale: The correct answer is C, Major Depressive Disorder. Latresha's symptoms of prolonged sadness, fatigue, and lack of interest in activities lasting for 2 months indicate a major depressive episode. Generalized anxiety disorder (A) is characterized by excessive worry and anxiety, not necessarily prolonged sadness. Bipolar disorder (B) involves episodes of both mania and depression, not solely prolonged sadness. Obsessive-compulsive disorder (D) is characterized by obsessions and compulsions, not the symptoms described in the scenario.
5. What neurotransmitter was first believed to be the cause of schizophrenia?
- A. GABA
- B. Serotonin
- C. Epinephrine
- D. Dopamine
Correct answer: D
Rationale: The correct answer is Dopamine. Dopamine was initially thought to be the primary cause of schizophrenia. This neurotransmitter hypothesis was based on the observation that drugs that increase dopamine activity can worsen symptoms of schizophrenia, while drugs that decrease dopamine activity can improve symptoms. Choices A, B, and C are incorrect because GABA, serotonin, and epinephrine were not the neurotransmitters initially believed to be the cause of schizophrenia.
