1. 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.

2. With which of the following statements would a behaviorist agree?

A. Conscious experiences can be studied in an objective, precise way.
B. In order to understand behavior, one must understand the motives behind the behavior.
C. Behavior can only be explained in terms of phenomenology, that is, an individual's interpretation of experience.
D. Psychology should be the science of behavior that can be observed by others.

Correct answer: D

Rationale: The correct answer is D. Behaviorists argue that psychology should focus on observable behavior that can be studied objectively. Choice A is incorrect because behaviorists do not typically focus on conscious experiences, as they are not directly observable. Choice B is incorrect because behaviorists emphasize that behavior can be understood without delving into internal motives. Choice C is incorrect as behaviorists do not exclusively explain behavior through an individual's interpretation of experience; they focus on observable actions and reactions.

3. 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.

4. Understanding the causes of mental disorders is important because ________

A. effective treatment is not possible without such an understanding.
B. classification of disorders cannot be done without such information.
C. such knowledge might make both the prevention and cure of mental disorders possible.
D. disagreements about the causes of psychopathology have long limited the advancements made in the study of abnormal psychology.

Correct answer: C

Rationale: Understanding the causes of mental disorders is crucial because it can potentially lead to both prevention and cure. By identifying the root causes, strategies can be developed to prevent the onset of disorders, and effective treatments can be tailored to address these causes directly. This approach can make treatments more efficient, as addressing the underlying factors contributing to the disorder can result in better outcomes for individuals. Choices A and B are incorrect because while understanding causes is important for effective treatment and classification, the primary focus is on prevention and cure. Choice D, while highlighting the impact of disagreements on advancements in abnormal psychology, does not directly address the importance of understanding causes for prevention and cure.

5. What role does brain development play in psychopathology?

A. Brain development has no impact on psychopathology.
B. Brain development plays a crucial role in the onset of many mental disorders.
C. Brain development is only linked to physical disabilities, not mental disorders.
D. Brain development is not associated with mental health.

Correct answer: B

Rationale: Brain development plays a crucial role in the onset of many mental disorders. It affects how the brain processes information and responds to stress, influencing the development of psychopathology. Choice A is incorrect as brain development does impact psychopathology. Choice C is incorrect as brain development is linked to mental disorders as well. Choice D is incorrect as brain development has implications for mental health.
