1. Roger has suffered a major brain injury. As a result, he is unable to speak fluently, tends to mispronounce words, and speaks haltingly. For instance, he says 'wat' instead of 'watch' and 'tot' instead of 'talk.' What is the diagnosis?

• A. Agnosia
• B. Spatial neglect
• C. Broca's aphasia
• D. Prosopagnosia

Correct answer: C

Rationale: The correct diagnosis for Roger's condition is Broca's aphasia. Broca's aphasia is characterized by difficulty in speaking fluently and accurately, often due to brain injury. In this case, Roger's symptoms of being unable to speak fluently, mispronouncing words, and speaking haltingly align with the characteristics of Broca's aphasia. Agnosia refers to the inability to recognize or interpret sensory information, spatial neglect is the lack of awareness of one side of the body or space, and prosopagnosia is the inability to recognize faces, none of which match Roger's symptoms.

2. What are genes made of?

• A. Trisomes
• B. Chromosomes
• C. DNA
• D. Proteins

Correct answer: C

Rationale: Genes are made of DNA, which is the genetic material that carries the instructions for the development, functioning, growth, and reproduction of organisms. While chromosomes contain genes, they are not what genes themselves are made of. Proteins are involved in gene expression and regulation, but they are not the primary material genes consist of. Trisomes is an incorrect term in this context and does not relate to the composition of genes.

3. How is pruning best defined?

• A. The process of eliminating unused synapses
• B. The process of synapse development
• C. The connection between neurons
• D. Fatty sheath that wraps around neurons and enables them to transmit information more rapidly

Correct answer: A

Rationale: Pruning is the process of eliminating unused synapses in the brain. This process helps the brain to become more efficient by strengthening important connections and eliminating unnecessary ones. Choice B is incorrect because pruning is about eliminating synapses, not developing them. Choice C is incorrect as it refers to the general concept of connections between neurons, not specifically about pruning. Choice D is incorrect as it describes the myelin sheath, which is responsible for rapid transmission of information along neurons, not pruning.

4. Which of the following perspectives focuses on social determinants of behavior?

• A. The attachment perspective
• B. The interpersonal perspective
• C. The humanistic perspective
• D. The existential perspective

Correct answer: B

Rationale: The interpersonal perspective focuses on social determinants of behavior, emphasizing the impact of social interactions, relationships, and communication on an individual's behavior. This perspective looks at how people's behavior is influenced by their interactions with others and the social environment. Choices A, C, and D are incorrect because they do not primarily focus on social determinants of behavior. The attachment perspective is concerned with emotional bonds between individuals, the humanistic perspective emphasizes personal growth and self-fulfillment, and the existential perspective focuses on individual freedom and responsibility in creating meaning in life.

5. Which of the following characteristics best describes differences between bulimia nervosa and anorexia nervosa?

• A. Individuals with anorexia nervosa do not have as severe health risks as individuals with bulimia nervosa have.
• B. Individuals with bulimia nervosa may have a normal body weight.
• C. Individuals with anorexia nervosa have been known to binge like those with bulimia nervosa on occasion.
• D. Only those with bulimia nervosa display compensatory behaviors.

Correct answer: B

Rationale: The correct answer is B. Individuals with bulimia nervosa may maintain a normal body weight, while anorexia nervosa is often associated with severe underweight. Choice A is incorrect because individuals with anorexia nervosa actually face severe health risks due to malnutrition, electrolyte imbalances, and other complications. Choice C is incorrect as anorexia nervosa is characterized by restriction of food intake rather than binge eating. Choice D is incorrect as individuals with anorexia nervosa can also display compensatory behaviors such as excessive exercise or fasting.
