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. In an experiment, the investigators manipulate variables to learn how one affects another.?

• A. A data-collection method in which participants respond to questions
• B. The entire group that is of interest to a researcher
• C. A detailed description of a single culture or context
• D. A study that tests a causal hypothesis

Correct answer: D

Rationale: The correct answer is D because in an experimental design, investigators manipulate variables to determine the effect of one on another. This process allows researchers to test causal hypotheses by manipulating one variable while keeping others constant. Choices A, B, and C are incorrect as they do not directly relate to manipulating variables in an experiment.

3. What role do genetic predispositions play in the development of mental disorders?

• A. Genetic predispositions solely determine the development of mental disorders.
• B. Genetic predispositions play a role but are not solely responsible for the development of mental disorders.
• C. Genetic predispositions have no influence on mental disorders.
• D. Genetic predispositions guarantee the development of mental disorders.

Correct answer: B

Rationale: Genetic predispositions are indeed a factor in the development of mental disorders, but they are not the sole determining factor. While genetics can predispose individuals to certain conditions, environmental factors, lifestyle choices, and life experiences also play a significant role. Choice A is incorrect because mental disorders are influenced by a combination of genetic and environmental factors. Choice C is incorrect as genetic predispositions do have an impact on mental health. Choice D is incorrect as genetic predispositions do not guarantee the development of mental disorders, as other factors also contribute to their onset.

4. Which of the following statements about brain dysfunction and psychiatric disorders is correct?

• A. Identifiable brain damage is often the cause of psychiatric disorders.
• B. Brain damage may decrease the risk of developing a psychiatric condition.
• C. Changes in brain function appear to play a role in many psychiatric disorders.
• D. Brain development can be altered by experience, always leading to changes in the brain that decrease the risk of developing a psychiatric condition.

Correct answer: C

Rationale: The correct statement is C: 'Changes in brain function appear to play a role in many psychiatric disorders.' This statement is accurate as research suggests that alterations in brain function are associated with various psychiatric disorders. Option A is incorrect because while brain damage can contribute to some psychiatric conditions, it is not always the primary cause. Option B is incorrect as brain damage typically increases the risk of developing psychiatric disorders. Option D is incorrect because while brain development can be influenced by experiences, it does not always decrease the risk of psychiatric conditions.

5. The humanistic perspective focuses primarily upon the capacity of the individual to ________.

• A. confront the dilemma of our deaths.
• B. be driven by unconscious motives.
• C. rationally explain our behavior.
• D. engage in positive self-growth.

Correct answer: D

Rationale: The humanistic perspective, as highlighted by proponents like Carl Rogers and Abraham Maslow, emphasizes the inherent drive of individuals to achieve self-actualization and positive self-growth. It focuses on the individual's potential for growth, self-improvement, and fulfilling their highest capabilities. Choice A is incorrect as the humanistic perspective is more concerned with personal growth than with addressing the fear of death. Choice B is associated with the psychodynamic perspective, which focuses on unconscious motives. Choice C is related to cognitive-behavioral approaches that emphasize the rational understanding of behavior.
