What is the result when a single zygote separates into two parts, each developing into a separate individual?
- A. Dizygotic twin
- B. Monozygotic twin
- C. Fraternal twin
- D. Nonidentical twin
Correct Answer: B
Rationale: The correct answer is B, Monozygotic twin. A monozygotic twin, also known as an identical twin, is the result when a single zygote splits into two parts, leading to the development of two genetically identical individuals. Choices A, C, and D are incorrect because they do not accurately describe the scenario where a single zygote splits into two parts to form identical twins. Dizygotic twin (Choice A) refers to fraternal twins, which result from two separate eggs fertilized by two different sperm cells. Fraternal twin (Choice C) is another term for dizygotic twins, arising from two separate zygotes. Nonidentical twin (Choice D) is a synonymous term for dizygotic or fraternal twins, indicating that they are not genetically identical.

- A. Secure
- B. Avoidant
- C. Ambivalent
- D. Disorganized
Correct Answer: C
Rationale: The correct answer is C: 'Ambivalent.' Children with an ambivalent temperament are indeed generally mild but hesitant about accepting new experiences.

Gabriel is depressed as he has been looking for a job for the past year without success. Today, his best friend tried to give him two books on job interviews, but he turned down the offer. What concept best explains his reaction?
- A. Observational learning
- B. Insight learning
- C. Learned helplessness
- D. Modeling
Correct Answer: C
Rationale: Gabriel's reaction of turning down the offer of job interview books from his friend despite being depressed and unsuccessful in job hunting best fits the concept of learned helplessness. Learned helplessness occurs when individuals believe they have no control over their situation, leading to passivity and feelings of helplessness. In this case, Gabriel's refusal of the books indicates a sense of resignation and belief that his efforts in finding a job will not be successful, reflecting learned helplessness. Observational learning, insight learning, and modeling do not directly align with Gabriel's reaction in this context.
Which of the following is true about subjective distress?
- A. All individuals with mental illness experience some degree of distress
- B. Distress is the only criterion in diagnosing abnormality
- C. Its presence is enough for a clinician to determine if someone has a mental illness
- D. Some individuals with a mental disorder may not experience subjective distress
Correct Answer: D
Rationale: Subjective distress is not universal among individuals with a mental disorder. Choice A is incorrect as not all individuals with mental illness experience distress. Choice B is incorrect because distress is just one of the criteria used in diagnosing abnormality, not the only one. Choice C is incorrect because the presence of subjective distress alone is not sufficient for a clinician to determine if someone has a mental illness.
The cognitive perspective contends that to fully understand human behavior, psychologists need to focus attention on?
- A. The role of the unconscious.
- B. Internal mental events.
- C. The interrelations among the mind, body, and behavior.
- D. The adaptive value of a behavior.
Correct Answer: B
Rationale: The cognitive perspective emphasizes understanding human behavior by focusing on internal mental events such as thoughts, beliefs, and perceptions. This helps in explaining how individuals process information, solve problems, and make decisions. Choice A, the role of the unconscious, is associated with psychoanalytic theory rather than the cognitive perspective. Choice C, the interrelations among the mind, body, and behavior, is more aligned with a holistic or biopsychosocial perspective. Choice D, the adaptive value of a behavior, is more related to evolutionary psychology rather than the cognitive perspective.
