1. 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.

2. What term describes exceptional mental abilities such as mental math, memorization, musical, and artistic ability found among individuals with autism?

• A. Savant skills
• B. Theory of mind
• C. Echolalia
• D. Self-stimulatory behaviors

Correct answer: A

Rationale: The correct answer is A: Savant skills. Savant skills refer to exceptional abilities commonly observed in individuals with autism. These skills can include remarkable talents in areas such as mental math, memorization, music, and art. Choice B, Theory of mind, is the ability to attribute mental states to oneself and others, which is a different concept. Choice C, Echolalia, is the repetition of words or phrases, not related to exceptional abilities. Choice D, Self-stimulatory behaviors, involves repetitive body movements or sounds often seen in individuals with autism but is not directly related to exceptional mental abilities.

3. Daniel is pretending that one of his blocks is a car. Daniel is exhibiting which function?

• A. Abstraction
• B. Preoperational
• C. Overextension
• D. Semiotic

Correct answer: A

Rationale: The correct answer is A: Abstraction. Pretending that a block is a car demonstrates abstraction, where one object is used to represent another. Choice B, Preoperational, refers to Piaget's stage of cognitive development. Choice C, Overextension, involves using a word in a broader context than is appropriate. Choice D, Semiotic, refers to the use of symbols to represent ideas or concepts, which is not directly related to the scenario described in the question.

4. Which school of psychology is associated with understanding the purpose of behavior?

• A. Functionalism.
• B. Behaviorism.
• C. Neodynamism.
• D. Psychoanalysis.

Correct answer: A

Rationale: The correct answer is A, Functionalism. Functionalism, founded by William James, emphasizes understanding the purpose and adaptive function of behavior. This school of psychology focuses on how mental processes help individuals adapt to their environment. Choice B, Behaviorism, is incorrect as behaviorism emphasizes observable behaviors rather than the purpose behind them. Choice C, Neodynamism, is not a recognized school of psychology. Choice D, Psychoanalysis, founded by Sigmund Freud, focuses on unconscious processes and early childhood experiences, not specifically on the purpose of behavior.

5. 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.
