1. What are substances, such as viruses and drugs, that can cause birth defects?

• A. Teratogens
• B. Placenta
• C. Parturition
• D. Androgens

Correct answer: A

Rationale: Teratogens are substances that can cause birth defects, especially if exposure occurs during critical periods of development. In this context, teratogens refer to external agents that can interfere with the development of the embryo or fetus, leading to structural or functional abnormalities. Choice B, Placenta, is incorrect as it is an organ that develops during pregnancy to provide nutrients and oxygen to the fetus and remove waste products. Choice C, Parturition, refers to the process of giving birth and is not related to substances that cause birth defects. Choice D, Androgens, are male sex hormones and are not associated with causing birth defects.

2. 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.

3. You are taking part in a survey that asks about your attitudes toward physical punishment of children. Even though you believe that spanking is sometimes necessary, you answer that you are opposed to any sort of physical punishment. Which of the following terms best describes why you answered the way you did?

• A. Random responding
• B. Faking bad
• C. Placebo effect
• D. Social desirability

Correct answer: D

Rationale: The correct answer is D, social desirability. Social desirability bias occurs when respondents answer questions in a way they think will be viewed favorably by others, rather than according to their true beliefs. In this scenario, the respondent may feel pressured to provide an answer that aligns with societal norms or expectations, even if it contradicts their personal beliefs. Choices A, B, and C are incorrect. Random responding refers to answering survey questions haphazardly, without consideration. Faking bad is intentionally providing extreme or negative responses. The placebo effect is a phenomenon where a person's belief in a treatment's effectiveness produces a positive outcome, unrelated to the treatment's actual effects.

4. What is extinction, and how might it be used in treating a disorder?

• A. Extinction strengthens the conditioned response by continuously pairing the conditioned stimulus with the unconditioned stimulus.
• B. Extinction is the process of eliminating a conditioned response by repeatedly presenting the conditioned stimulus without the unconditioned stimulus.
• C. Extinction is ineffective and is not used in treating disorders.
• D. Extinction is the process of intensifying the conditioned response by pairing the conditioned stimulus with a stronger unconditioned stimulus.

Correct answer: B

Rationale: Extinction is the process of eliminating a conditioned response by repeatedly presenting the conditioned stimulus without the unconditioned stimulus. This process helps in reducing or eliminating undesired behaviors or responses. Choice A is incorrect because extinction weakens the conditioned response by breaking the association between the conditioned stimulus and the unconditioned stimulus. Choice C is incorrect as extinction is a widely used technique in behavioral therapies for treating disorders. Choice D is incorrect as extinction aims to reduce the conditioned response, not intensify it.

5. Children whose temperament is generally mild but who are hesitant about accepting new experiences are described as?

• A. Secure
• B. Avoidant
• C. Ambivalent
• D. Disorganized

Correct answer: C

Rationale: The correct answer is C: 'Ambivalent.' Children with an ambivalent temperament are indeed generally mild but hesitant about accepting new experiences. This temperament is characterized by a combination of mildness and hesitance. Choice A, 'Secure,' refers to children who are comfortable with both their caregiver's presence and absence, showing a secure attachment style. Choice B, 'Avoidant,' describes children who tend to avoid or ignore their caregiver, displaying an insecure attachment style. Choice D, 'Disorganized,' represents children with inconsistent or confused behaviors towards their caregiver, exhibiting an insecure and disoriented attachment style.
