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.

One key issue in the study of human development is the continuity-discontinuity issue. The discontinuity side posits that development is characterized by change in type or kind. These are known as ____.
- A. Qualitative change
- B. Quantitative change
- C. Maturation
- D. Multidirectional development
Correct Answer: A
Rationale: The correct answer is A: Qualitative change. Qualitative change aligns with the discontinuity view by involving changes in type or kind. This contrasts with quantitative change (B), which is about changes in amount or quantity. Maturation (C) refers to the process of becoming fully developed in a particular way, and multidirectional development (D) emphasizes that development involves both gains and losses, not specifically focusing on changes in type or kind.
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.
What is the term for the age of an unborn baby, usually dated from the first day of an expectant mother's last menstrual cycle?
- A. Mental age
- B. Chronological age
- C. Functional age
- D. Gestational age
Correct Answer: D
Rationale: The correct answer is D, Gestational age. Gestational age is calculated from the first day of the expectant mother's last menstrual cycle, providing an estimate of how far along the pregnancy is. Mental age (choice A), refers to an individual's level of cognitive functioning in relation to others of the same age group. Chronological age (choice B) is a person's actual age in years. Functional age (choice C) refers to how well a person is able to perform various activities compared to their chronological age.
In defining a mental disorder, deviance refers to?
- A. Amount of suffering the individual is experiencing due to the mental disorder
- B. Inability of an individual to fulfill a certain role (e.g., work or family obligation)
- C. The capacity of the individual to cause harm to the people around them
- D. The tendency of an individual to display behaviors that are culturally unexpected
Correct Answer: D
Rationale: In defining a mental disorder, deviance refers to behavior that is culturally unexpected or violates social norms. This means that the individual displays behaviors that are not typical or acceptable within their specific culture or society. Choices A, B, and C are incorrect because they do not directly relate to the concept of deviance in the context of defining a mental disorder. The amount of suffering, inability to fulfill a role, or capacity to cause harm are important considerations in understanding mental disorders but are not specifically related to deviance.
Behaviors that deviate from the norm are?
- A. Always seen as a disorder if they violate social norms
- B. Considered a disorder regardless of culture
- C. Typically seen as a disorder when they impair functioning
- D. Never considered as a sign of abnormality
Correct Answer: C
Rationale: Behaviors that deviate from the norm are typically considered disorders when they impair functioning. Choice A is incorrect because not all behaviors that deviate from the norm are considered disorders; they need to impair functioning. Choice B is incorrect because the cultural context plays a significant role in determining what is considered abnormal. Choice D is incorrect because behaviors that deviate from the norm can indeed be considered signs of abnormality, especially if they impair functioning.
