1. An inborn trait that is relatively permanent and differentiates one person from another is known as ________.

• A. genotype
• B. phenotype
• C. temperament
• D. characteristic

Correct answer: C

Rationale: Temperament is the correct answer because it refers to an individual's inborn, relatively permanent trait that distinguishes one person from another. Genotype (choice A) refers to the genetic makeup of an organism, not necessarily a behavioral trait. Phenotype (choice B) is the observable characteristics of an organism resulting from the interaction between its genotype and the environment. Characteristic (choice D) is a broad term that can encompass various traits and features, but it does not specifically denote an inborn and relatively permanent trait that sets individuals apart.

2. A predisposition toward developing a disorder is termed a ________.

• A. diathesis
• B. comorbidity
• C. genotype
• D. phenotype

Correct answer: A

Rationale: A diathesis is indeed the correct term for a predisposition toward developing a disorder. A diathesis refers to an underlying vulnerability or predisposition to a particular condition. Choice B, 'comorbidity,' refers to the presence of two or more disorders in the same individual. Choice C, 'genotype,' relates to an individual's genetic makeup. Choice D, 'phenotype,' refers to the observable characteristics of an organism resulting from the interaction of its genotype with the environment. Therefore, A is the most appropriate term for describing a predisposition toward developing a disorder.

3. What does incidence refer to?

• A. How many new cases of a disorder occur during a given period of time
• B. How many people have recovered from a disorder in a given period of time
• C. The percentage of males and females who have a disorder
• D. How many people in the population as a whole have a disorder

Correct answer: A

Rationale: The correct answer is A: 'How many new cases of a disorder occur during a given period of time.' Incidence specifically measures the rate of occurrence of new cases of a particular condition within a defined population and time frame. This distinguishes it from prevalence, which includes both new and existing cases. Choices B, C, and D are incorrect because they do not accurately define the term 'incidence.' Choice B refers to recovery, choice C mentions gender distribution, and choice D relates to the total population affected by a disorder, which are not reflective of the concept of incidence.

4. 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.

5. How does stress impact brain function?

• A. Stress has no effect on brain function.
• B. Stress can lead to changes in brain structure and function.
• C. Stress can improve brain function.
• D. Stress has no long-term impact on brain function.

Correct answer: B

Rationale: Stress can lead to changes in brain structure and function, affecting mental health and increasing the risk of disorders. Choice A is incorrect as stress does affect brain function. Choice C is incorrect as stress generally has negative impacts on brain function rather than improving it. Choice D is incorrect because stress can have long-term impacts on brain function through structural and functional changes.
