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. How does abuse and maltreatment tend to affect a child's ability to relate to others?

• A. It leads to the development of strong, healthy relationships.
• B. It results in difficulty forming healthy relationships later in life.
• C. It has little to no impact on a child's social development.
• D. It promotes independence in forming new relationships.

Correct answer: B

Rationale: The correct answer is B. Abuse and maltreatment tend to result in difficulties in forming healthy relationships and may lead to a disorganized and disoriented attachment style. Choice A is incorrect because abuse and maltreatment usually hinder the development of strong and healthy relationships. Choice C is incorrect as abuse and maltreatment significantly impact a child's social development. Choice D is incorrect because abuse and maltreatment do not promote independence in forming new relationships but rather create barriers to forming healthy connections.

3. Freud's psychosexual stage that occurs between the ages of 3 and 5 is the ________ stage.

• A. oral
• B. anal
• C. phallic
• D. genital

Correct answer: C

Rationale: Freud's psychosexual stage that occurs between the ages of 3 and 5 is the phallic stage. During this stage, children focus on the genitals and start to identify with the same-sex parent while developing the superego. Choice A, the oral stage, occurs during infancy (0-1 year), where gratification is centered around the mouth. Choice B, the anal stage, occurs between the ages of 1 and 3, focusing on toilet training. Choice D, the genital stage, is the final stage in Freud's theory, occurring from puberty onwards, where the focus is on mature sexual relationships.

4. If having a gene for Parkinson's disease guarantees that Parkinson's disease will develop, the gene is a ________.

• A. risk factor
• B. necessary cause
• C. sufficient cause
• D. contributory cause

Correct answer: B

Rationale: The correct answer is B: necessary cause. A necessary cause is an essential factor for the disorder to occur. In this scenario, if having a gene for Parkinson's disease guarantees the development of the disease, then the gene is a necessary cause. Choice A, 'risk factor,' implies an increased likelihood of developing the disease but does not indicate certainty. Choice C, 'sufficient cause,' indicates that the gene alone can bring about the disease, which is not necessarily true in this context. Choice D, 'contributory cause,' suggests that the gene plays a part in causing the disease but is not essential for its development.

5. While out for a walk, you come across a ferocious dog. You feel your heart beating faster and your palms begin to sweat. Which part of the peripheral nervous system is activated in this situation?

• A. Autonomic
• B. Sympathetic
• C. Parasympathetic
• D. Somatic

Correct answer: B

Rationale: The correct answer is B: Sympathetic. When encountering a stressful situation like a ferocious dog, the sympathetic nervous system is activated, leading to the 'fight or flight' response. This response triggers physiological changes like increased heart rate, sweating, and heightened alertness to prepare the body to deal with the perceived threat. The autonomic nervous system (Choice A) encompasses both the sympathetic and parasympathetic divisions, so it's a broader category. The parasympathetic nervous system (Choice C) is responsible for the body's 'rest and digest' functions, which are opposite to the physiological changes seen in a stress response. The somatic nervous system (Choice D) controls voluntary movements and sensory information, not the physiological responses seen in a stress reaction.
