Exam 4 Psychology
1. Nearly all adults who were children living in Saigon when the U.S. armed forces left Vietnam in 1975 report that their lives were changed by those events. This exemplifies which of the following?
- A. Normative age-graded influence
- B. Social clock
- C. Critical period
- D. Sensitive period
Correct answer: C
Rationale: The correct answer is C. This scenario exemplifies a critical period in development. Critical periods are specific times in an individual's life when certain events have a profound impact on their development. In this case, the events surrounding the departure of the U.S. armed forces from Saigon in 1975 had a lasting influence on the children living there at that time. Choices A, B, and D are incorrect. Normative age-graded influence refers to events that are common to people of a particular age group, the social clock relates to the culturally preferred timing of social events, and a sensitive period is a time when an individual is more susceptible to environmental influences but does not result in lifelong consequences as with critical periods.
2. A psychological disorder is said to have an acute onset if the symptoms develop ______, while it has an insidious onset if the symptoms develop ______.
- A. Suddenly;gradually
- B. Suddenly;atypically
- C. Gradually;atypically
- D. Atypically;suddenly
Correct answer: A
Rationale: An acute onset refers to the sudden development of symptoms, whereas an insidious onset indicates a gradual progression of symptoms. Therefore, the correct answer is 'Suddenly;gradually.' The other choices are incorrect because 'atypically' does not accurately describe the onset of symptoms in this context.
3. Which part of your brain is active when you get cues about being hungry, thirsty, or sleepy?
- A. Hippocampus
- B. Thalamus
- C. Hypothalamus
- D. Amygdala
Correct answer: C
Rationale: The correct answer is the Hypothalamus (Choice C). The hypothalamus plays a crucial role in regulating basic bodily functions such as hunger, thirst, and sleep. It receives cues related to these needs and helps to maintain homeostasis in the body. The Hippocampus (Choice A) is primarily involved in memory formation and spatial navigation, not in regulating physiological needs. The Thalamus (Choice B) acts as a relay station for sensory information but is not the main center for hunger, thirst, or sleep regulation. The Amygdala (Choice D) is more associated with emotions, particularly fear and pleasure, rather than physiological needs like hunger, thirst, or sleep.
4. 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.
5. Genes ________.
- A. determine how a person will behave.
- B. cause people to develop mental disorders.
- C. determine what characteristics a person will have.
- D. determine the range of characteristics a person has.
Correct answer: D
Rationale: Genes determine the range of characteristics a person has. This is the correct answer because genes contribute to a variety of traits and characteristics a person may have, influencing physical attributes, predispositions to certain conditions, and more. Choice A is incorrect because behavior is influenced by a combination of genetic and environmental factors. Choice B is incorrect because mental disorders are complex conditions influenced by various factors beyond just genes. Choice C is incorrect because genes do not solely determine all characteristics a person will have, as environmental factors also play a significant role.
