Exam 4 Psychology Questions
Question 1 of 5
What did Freud believe about castration anxiety among boys?
Correct Answer: B
Rationale: Freud believed that castration anxiety among boys leads to the resolution of the Oedipus complex, not penis envy or cognitive learning. The Oedipus complex is a central psychodynamic concept in Freudian theory, where boys develop unconscious desires for their mothers and view their fathers as rivals, fearing castration by their fathers as a consequence.
Question 2 of 5
During conception, the 23 unpaired chromosomes in the ovum and sperm combine to form 23 pairs in an entirely new cell called the?
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.
Question 3 of 5
In order for one to have a recessive trait (e.g., having red hair), the person must receive?
Correct Answer: B
Rationale: Recessive traits are expressed when an individual inherits two copies of the recessive gene, one from each parent. Therefore, the correct answer is B. Choice A is incorrect as one copy of a recessive gene is not sufficient to display a recessive trait. Choice C is incorrect because having at least one copy of a dominant gene is unrelated to expressing a recessive trait. Choice D is incorrect because two copies of a recessive gene must come from both parents, not just one.
Question 4 of 5
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?
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.
Question 5 of 5
What are substances, such as viruses and drugs, that can cause birth defects?
Correct Answer: A
Rationale: Teratogens are substances that can cause birth defects, especially if exposure occurs during critical periods of development. In this context, teratogens refer to external agents that can interfere with the development of the embryo or fetus, leading to structural or functional abnormalities. Choice B, Placenta, is incorrect as it is an organ that develops during pregnancy to provide nutrients and oxygen to the fetus and remove waste products. Choice C, Parturition, refers to the process of giving birth and is not related to substances that cause birth defects. Choice D, Androgens, are male sex hormones and are not associated with causing birth defects.
