1. 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 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 extra copy of chromosome 21, also known as trisomy 21, leads to the characteristic features and health problems associated with Down syndrome.

2. The process of ________ is used to increase the probability that a behavior will occur.

• A. operant conditioning
• B. reinforcement
• C. classical conditioning
• D. punishment

Correct answer: B

Rationale: The correct answer is reinforcement. Reinforcement involves providing a consequence that increases the likelihood of a behavior being repeated. Operant conditioning (Choice A) refers to learning through consequences for behavior, which includes reinforcement and punishment. Classical conditioning (Choice C) involves forming associations between stimuli and involuntary responses. Punishment (Choice D) involves providing a consequence that decreases the likelihood of a behavior being repeated. In this context, the question specifically asks about a process that increases the probability of a behavior occurring, aligning with the concept of reinforcement.

3. 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.

4. Kai and Ken received their Christmas gifts from their parents. Although their gifts vary in many characteristics, the two compared their gifts based on size. This tendency among children is known as:

• A. Semiotic
• B. Abstraction
• C. Preoperational
• D. Overextension

Correct answer: D

Rationale: The correct answer is D, Overextension. Overextension happens when children compare objects or experiences based on one characteristic, such as size. Choices A, B, and C are incorrect. Semiotic refers to the study of signs and symbols; Abstraction is the process of thinking about something as a general concept rather than a specific example; Preoperational is a stage in Piaget's theory of cognitive development, not related to comparing gifts based on size.

5. Jason, a 4-year-old boy, believes that it gets cloudy and rainy every time he is sad. He concluded that his sadness is the cause of the bad weather. This tendency is known as?

• A. Irreversibility
• B. Centration
• C. Animism
• D. Transduction

Correct answer: D

Rationale: The correct answer is D, Transduction. Transduction refers to when a child believes that their feelings or actions cause unrelated events, such as a child thinking their sadness causes rain. Choice A, Irreversibility, is incorrect as it relates to the belief that actions cannot be undone, which is more related to conservation tasks in Piaget's theory. Choice B, Centration, refers to the tendency to focus on only one aspect of a situation, overlooking other relevant aspects. Choice C, Animism, is the attribution of lifelike qualities to inanimate objects, which is not applicable in this scenario.
