1. Genes ________

A. determine how a person will behave.
B. cause people to develop mental disorders.
C. determine what characteristics a person will have.
D. determine the range of characteristics a person has.

Correct answer: D

Rationale: Genes determine the range of characteristics a person has. Choice A is incorrect because genes do not solely determine behavior, as behavior is influenced by a combination of genetic and environmental factors. Choice B is incorrect because while genes can contribute to the risk of developing mental disorders, they do not directly cause them. Choice C is incorrect as genes contribute to but do not solely determine all characteristics a person will have.

2. What is a person's total genetic endowment?

A. Phenotype
B. Genotype
C. Chromosomes
D. DNA

Correct answer: B

Rationale: The correct answer is B: Genotype. A genotype refers to a person's total genetic endowment, representing the specific genetic makeup inherited from their parents. This includes all the genes and genetic information contained in an individual's DNA. Choices A, C, and D are incorrect because: A) Phenotype refers to the observable characteristics resulting from the interaction of genetics and the environment; C) Chromosomes are physical structures that contain genes, not the total genetic endowment itself; D) DNA carries genetic information but is just one component of an individual's total genetic endowment.

3. What did Freud believe about castration anxiety among boys?

A. Results in penis envy.
B. Dissolves the Oedipus complex.
C. Cognitive; learning.
D. Biological; ecological.

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.

4. Which term describes a combination of economic and social factors detailing an individual or family's position, including income, education, and occupation?

A. Culture
B. Socioeconomic status
C. Risk factors
D. Ethnic gloss

Correct answer: B

Rationale: The correct answer is B: Socioeconomic status. Socioeconomic status (SES) is a term used to combine economic and social factors to describe an individual's or family's position in society. Choice A, Culture, refers to the beliefs, customs, and practices of a specific group of people. Choice C, Risk factors, are characteristics or exposures that increase the likelihood of developing a disease or injury. Choice D, Ethnic gloss, is not a term related to the description of an individual or family's economic and social position.

5. A baby throws its arms out and then inward (as if embracing) in response to loud noise or when its head falls. Which reflex is this?

A. Babinski
B. Palmar
C. Darwinian
D. Moro

Correct answer: D

Rationale: The correct answer is D, Moro. The Moro reflex is an instinctual response seen in infants when they experience a sudden loss of support or loud noise. The baby will throw their arms out and then bring them back in, resembling an embrace. This reflex is important for survival as it helps the infant react to potential dangers. Choice A, Babinski, refers to the reflex where a baby's toes spread apart when the sole of the foot is stimulated. Choice B, Palmar, is related to the reflex where a baby's fingers close tightly around an object placed in their palm. Choice C, Darwinian, is not a recognized reflex in this context.
