Exam 4 Psychology
1. Franklin wakes up in a homeless shelter in another town. He doesn't know where he is or how he got there, and he's confused when people say he has been calling himself Anthony. This is most likely an episode of dissociative?
- A. Amnesia
- B. Dissociative fugue
- C. Wandering
- D. Flight of ideas
Correct answer: B
Rationale: The correct answer is B, Dissociative fugue. In the scenario described, Franklin experiencing memory loss, travel to another town, assuming a new identity (calling himself Anthony) aligns with dissociative fugue. Amnesia (Choice A) involves memory loss without the additional aspects of travel and assuming a new identity. Wandering (Choice C) is vague and does not encompass the complete set of symptoms described. Flight of ideas (Choice D) is a symptom of conditions like mania, not dissociative disorders.
2. Who took the position that organisms tend to repeat responses that lead to positive outcomes and tend not to repeat responses that lead to neutral or negative outcomes?
- A. Sigmund Freud
- B. B.F. Skinner
- C. Carl Rogers
- D. Abraham Maslow
Correct answer: B
Rationale: The correct answer is B.F. Skinner. Skinner proposed the theory of operant conditioning, where behavior is shaped by its consequences. Positive outcomes increase the likelihood of a behavior being repeated, while neutral or negative outcomes decrease it. Sigmund Freud (choice A) is known for his psychoanalytic theory, Carl Rogers (choice C) for person-centered therapy, and Abraham Maslow (choice D) for the hierarchy of needs.
3. In order for one to have a recessive trait (e.g., having red hair), the person must receive?
- A. At least one copy of a recessive gene from a parent
- B. Two copies of a recessive gene, one from each parent
- C. At least one copy of a recessive gene and at least one copy of a dominant gene
- D. At least two copies of a recessive gene from one parent
Correct answer: B
Rationale: Recessive traits are expressed when an individual inherits two copies of the recessive gene, one from each parent. Therefore, the correct answer is B. Choice A is incorrect as one copy of a recessive gene is not sufficient to display a recessive trait. Choice C is incorrect because having at least one copy of a dominant gene is unrelated to expressing a recessive trait. Choice D is incorrect because two copies of a recessive gene must come from both parents, not just one.
4. How is pruning best defined?
- A. The process of eliminating unused synapses
- B. The process of synapse development
- C. The connection between neurons
- D. Fatty sheath that wraps around neurons and enables them to transmit information more rapidly
Correct answer: A
Rationale: Pruning is the process of eliminating unused synapses in the brain. This process helps the brain to become more efficient by strengthening important connections and eliminating unnecessary ones. Choice B is incorrect because pruning is about eliminating synapses, not developing them. Choice C is incorrect as it refers to the general concept of connections between neurons, not specifically about pruning. Choice D is incorrect as it describes the myelin sheath, which is responsible for rapid transmission of information along neurons, not pruning.
5. 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.
