1. How does the concept of neural plasticity relate to recovery from brain injuries?

• A. Neural plasticity means the brain cannot recover from injuries.
• B. Neural plasticity allows the brain to recover and reorganize after injuries.
• C. Neural plasticity refers to the brain's inability to change after injury.
• D. Neural plasticity is a myth.

Correct answer: B

Rationale: Neural plasticity allows the brain to recover and reorganize after injuries. It is the brain's ability to adapt and change, forming new connections or reorganizing existing ones to compensate for damage. Choice A is incorrect as neural plasticity enables recovery. Choice C is incorrect as neural plasticity involves the brain's capacity to change. Choice D is incorrect as neural plasticity is a well-established phenomenon in neuroscience.

2. 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.

3. Genes ________

• A. determine how a person will behave.
• B. cause people to develop mental disorders.
• C. determine what characteristics a person will have.
• D. determine the range of characteristics a person has.

Correct answer: D

Rationale: Genes determine the range of characteristics a person has. Choice A is incorrect because genes do not solely determine behavior, as behavior is influenced by a combination of genetic and environmental factors. Choice B is incorrect because while genes can contribute to the risk of developing mental disorders, they do not directly cause them. Choice C is incorrect as genes contribute to but do not solely determine all characteristics a person will have.

4. What term describes exceptional mental abilities such as mental math, memorization, musical, and artistic ability found among individuals with autism?

• A. Savant skills
• B. Theory of mind
• C. Echolalia
• D. Self-stimulatory behaviors

Correct answer: A

Rationale: The correct answer is A: Savant skills. Savant skills refer to exceptional abilities commonly observed in individuals with autism. These skills can include remarkable talents in areas such as mental math, memorization, music, and art. Choice B, Theory of mind, is the ability to attribute mental states to oneself and others, which is a different concept. Choice C, Echolalia, is the repetition of words or phrases, not related to exceptional abilities. Choice D, Self-stimulatory behaviors, involves repetitive body movements or sounds often seen in individuals with autism but is not directly related to exceptional mental abilities.

5. What is the sequence in which growth starts at the center of the body and moves toward the extremities?

• A. Cephalocaudal pattern
• B. Proximodistal pattern
• C. Cephamodistal pattern
• D. Gene-environment correlation

Correct answer: B

Rationale: The correct answer is B: Proximodistal pattern. This pattern describes growth starting at the center of the body and moving towards the extremities. Choice A, Cephalocaudal pattern, refers to growth starting from the head and moving downwards, which is not the sequence described in the question. Choice D, Gene-environment correlation, does not relate to the sequential pattern of growth described in the question, making it incorrect.
