Psychology 101 Final Exam
1. Down syndrome is caused by ________
- A. a chemical imbalance.
- B. a gene on the X chromosome.
- C. possessing an extra X chromosome.
- D. possessing an extra chromosome in chromosome 21.
Correct answer: D
Rationale: Down syndrome is caused by possessing an extra chromosome in chromosome 21, not a chemical imbalance (choice A), a gene on the X chromosome (choice B), or possessing an extra X chromosome (choice C). The presence of an extra copy of chromosome 21, also known as trisomy 21, leads to the characteristic features and health problems associated with Down syndrome.
2. Which characteristics are associated with adults fixated in the anal stage?
- A. Orderliness, obstinacy, or messiness
- B. Fixated in the oral stage
- C. Dissolves the electra complex
- D. Triggers penis envy, which then dissolves the female oedipus complex
Correct answer: A
Rationale: The correct answer is A: 'Orderliness, obstinacy, or messiness.' According to Freud's psychosexual theory, fixation in the anal stage can lead to these characteristics in adulthood. Choice B is incorrect as fixation in the oral stage is associated with issues related to dependency and aggression. Choice C is incorrect as it refers to the Electra complex, which is not related to the anal stage fixation. Choice D is incorrect as it refers to penis envy and the female Oedipus complex, which are not directly related to characteristics of adults fixated in the anal stage.
3. Arrange the three stages of prenatal development in the correct order.
- A. Germinal stage, fetal stage, embryonic stage
- B. Fetal stage, embryonic stage, germinal stage
- C. Embryonic stage, germinal stage, fetal stage
- D. Germinal stage, embryonic stage, fetal stage
Correct answer: D
Rationale: The correct order of the three stages of prenatal development is germinal stage, embryonic stage, and fetal stage. During the germinal stage, the fertilized egg rapidly divides and implants in the uterine wall. The embryonic stage follows, where major organs and systems begin to develop. Finally, during the fetal stage, the developing organism is known as a fetus and continues to grow and mature. Choice A is incorrect because it has the stages in the wrong order. Choice B is incorrect as it also presents the stages out of order. Choice C is incorrect as it reverses the order of the stages. Therefore, the correct answer is D.
4. Which disorder is characterized by a pattern of behavior that involves culturally inappropriate, overly familiar behavior with relative strangers?
- A. Schizoid personality disorder
- B. Autism spectrum disorder
- C. Reactive attachment disorder
- D. Disinhibited social engagement disorder
Correct answer: D
Rationale: Disinhibited social engagement disorder is the correct answer because it is characterized by a pattern of behavior involving culturally inappropriate and overly familiar behavior with relative strangers. This disorder is marked by a lack of social boundaries and caution when interacting with unfamiliar individuals. Schizoid personality disorder (Choice A) is characterized by a lack of interest in social relationships, Autism spectrum disorder (Choice B) involves challenges with social interactions and communication, and Reactive attachment disorder (Choice C) is typically associated with difficulty forming emotional bonds with caregivers, not with overly familiar behavior with strangers.
5. The process of ________ is used to increase the probability that a behavior will occur.
- A. operant conditioning
- B. reinforcement
- C. classical conditioning
- D. punishment
Correct answer: B
Rationale: The correct answer is reinforcement. Reinforcement involves providing a consequence that increases the likelihood of a behavior being repeated. Operant conditioning (Choice A) refers to learning through consequences for behavior, which includes reinforcement and punishment. Classical conditioning (Choice C) involves forming associations between stimuli and involuntary responses. Punishment (Choice D) involves providing a consequence that decreases the likelihood of a behavior being repeated. In this context, the question specifically asks about a process that increases the probability of a behavior occurring, aligning with the concept of reinforcement.
