1. The genetic influences that determine behavior may never be fully understood due to ________

• A. the ease of researching to differentiate between the effects of the environment and the effects of genes.
• B. the likelihood that most behaviors are determined by the interaction of many genes and the environment.
• C. the tendency to rely on twin studies in genetic research.
• D. our significant understanding of how genes impact brain chemistry.

Correct answer: B

Rationale: The correct answer is B because most behaviors are influenced by a complex interaction of many genes and the environment. Choice A is incorrect because it states that it is easy to differentiate between the effects of the environment and genes, which is not the case. Choice C is incorrect because although twin studies are commonly used in genetic research, this alone does not hinder the full understanding of genetic influences on behavior. Choice D is incorrect because even though we have some understanding of how genes impact brain chemistry, this does not mean that we fully understand the genetic influences on behavior.

2. How do early life experiences shape brain development and behavior?

• A. Early life experiences have no impact on brain development.
• B. Early life experiences are crucial in shaping brain development and later behavior.
• C. Early life experiences are not significant in brain development.
• D. Early life experiences are easily overcome by adulthood.

Correct answer: B

Rationale: Early life experiences are crucial in shaping brain development and later behavior. These experiences play a significant role in laying the foundation for future mental health and behavior. Choice A is incorrect because early life experiences do have a profound impact on brain development. Choice C is incorrect as early life experiences are indeed significant in brain development. Choice D is incorrect as early life experiences can have lasting effects into adulthood.

3. Isabel is listening to a piece of classical music and tape recording all her feelings and impressions as she experiences them. Isabel is using a technique similar to the research methodology of?

• A. Structuralism.
• B. Functionalism.
• C. Behaviorism.
• D. Humanism.

Correct answer: A

Rationale: The correct answer is A: Structuralism. Structuralism involves introspection, where individuals report their thoughts and feelings while engaging with stimuli. In this scenario, Isabel is recording her feelings and impressions while listening to music, which aligns with the introspective nature of structuralism. Choices B, C, and D are incorrect because functionalism focuses on the purpose of behaviors, behaviorism emphasizes observable behaviors and environmental influences, and humanism highlights individual growth and personal experiences rather than introspection.

4. Children raised in orphanages tend to have ________.

• A. more cortical gray matter than those raised by their parents.
• B. less cortical gray matter than those raised by their parents.
• C. more friendships than those raised by their parents.
• D. fewer friendships than those raised by their parents.

Correct answer: B

Rationale: The correct answer is B: 'less cortical gray matter than those raised by their parents.' Studies have shown that children raised in orphanages tend to have less cortical gray matter compared to those raised by their parents. This is due to the lack of individualized care, attention, and stimulation that can negatively impact brain development. Choices A, C, and D are incorrect because there is no direct correlation between cortical gray matter and the number of friendships when comparing children raised in orphanages and those raised by their parents.

5. What is the term for a fluid-filled sac in which the baby floats until just before it is born?

• A. Amnion
• B. Placenta
• C. Umbilical cord
• D. Embryo

Correct answer: A

Rationale: The correct answer is A: Amnion. The amnion is a fluid-filled sac that surrounds and protects the developing fetus in the womb. It acts as a cushion, maintaining a stable temperature and protecting the fetus from external pressure. Choices B, C, and D are incorrect because the placenta is an organ that provides nutrients and oxygen to the fetus and removes waste products, the umbilical cord connects the fetus to the placenta to facilitate nutrient exchange, and an embryo is an early stage of development before it becomes a fetus.
