1. Which of the following is not a common method for studying genetic influences?

• A. The study of specific gene defects
• B. Twin studies
• C. Adoption studies
• D. Family history (pedigree) studies

Correct answer: A

Rationale: The correct answer is A. Studying specific gene defects is not a common method for investigating genetic influences. Choices B, C, and D are common methods used in genetic research. Twin studies help determine the heritability of traits, adoption studies compare similarities between adopted individuals and their adoptive families versus biological families, and family history studies track the inheritance patterns of traits within families.

2. Down syndrome is caused by ________.

• A. a chemical imbalance.
• B. a gene on the X chromosome.
• C. possessing an extra X chromosome.
• D. possessing an extra chromosome in chromosome 21.

Correct answer: D

Rationale: Down syndrome is caused by possessing an extra chromosome in chromosome 21, not by a chemical imbalance (choice A), a gene on the X chromosome (choice B), or possessing an extra X chromosome (choice C). The presence of an additional chromosome 21 disrupts the normal course of development and leads to the characteristics associated with Down syndrome.

3. _______ memory stores information about facts, whereas _______ memory stores information about our personal experiences.

• A. Declarative, episodic
• B. Episodic, semantic
• C. Semantic, nondeclarative
• D. Semantic, episodic

Correct answer: D

Rationale: The correct answer is D: "Semantic, episodic." Semantic memory is responsible for storing factual information, such as concepts and general knowledge. Episodic memory, on the other hand, stores personal experiences and events. Choice A is incorrect because declarative memory is an umbrella term that includes both semantic and episodic memory, so it is not a direct contrast. Choice B is incorrect as it switches the definitions of episodic and semantic memory. Choice C is incorrect because nondeclarative memory refers to implicit or procedural memory, which is different from episodic memory.

4. Which part of your brain is active when you get cues about being hungry, thirsty, or sleepy?

• A. Hippocampus
• B. Thalamus
• C. Hypothalamus
• D. Amygdala

Correct answer: C

Rationale: The correct answer is the Hypothalamus (Choice C). The hypothalamus plays a crucial role in regulating basic bodily functions such as hunger, thirst, and sleep. It receives cues related to these needs and helps to maintain homeostasis in the body. The Hippocampus (Choice A) is primarily involved in memory formation and spatial navigation, not in regulating physiological needs. The Thalamus (Choice B) acts as a relay station for sensory information but is not the main center for hunger, thirst, or sleep regulation. The Amygdala (Choice D) is more associated with emotions, particularly fear and pleasure, rather than physiological needs like hunger, thirst, or sleep.

5. What are the potential effects of childhood trauma on adult behavior?

• A. Childhood trauma is typically overcome by adulthood.
• B. Childhood trauma can have long-lasting effects on adult behavior.
• C. Childhood trauma has minimal impact on adult behavior.
• D. Childhood trauma is easily overcome with age.

Correct answer: B

Rationale: Childhood trauma can have profound and lasting effects on behavior and mental health in adulthood. It can lead to various issues such as anxiety, depression, PTSD, and difficulties in forming relationships. Choice A is incorrect because childhood trauma doesn't automatically disappear with age. Choice C is incorrect as research shows that childhood trauma can significantly impact adult behavior. Choice D is incorrect as overcoming childhood trauma is usually a complex and challenging process that may require therapy and support.
