1. Baby Gabriella claps her hands after her mother does. Gabriella is displaying __________.

• A. reinforcement
• B. classical conditioning
• C. observational learning
• D. adaptation

Correct answer: C

Rationale: Observational learning is when an individual learns by watching others and mimicking their actions or behaviors. In this scenario, Baby Gabriella claps her hands after her mother does, indicating she is learning through observing her mother's behavior and imitating it. The other choices are incorrect: Reinforcement typically involves a consequence that strengthens a behavior, classical conditioning is a type of learning where an association is made between two stimuli, and adaptation refers to the process of adjusting to new conditions.

2. Which statement about a blastocyst is true?

• A. It consists of a single cell.
• B. It is a structure that feeds the developing organism.
• C. Between the seventh and ninth days, it burrows deep into the uterine lining.
• D. It is a membrane that helps to keep the temperature of the prenatal world constant.

Correct answer: C

Rationale: The statement that is true about a blastocyst is that between the seventh and ninth days, it burrows deep into the uterine lining. This process, known as implantation, is essential for the blastocyst to establish a connection with the mother's body and receive nutrients for further development. It is a critical stage in prenatal development and sets the foundation for pregnancy. Choices A, B, and D are incorrect. A blastocyst is not a single cell but rather a structure composed of many cells. It is not a structure that feeds the developing organism; instead, it implants in the uterine lining to receive nutrients. It is not a membrane that regulates temperature but plays a crucial role in the initial stages of pregnancy by implanting in the uterus.

3. Adults often provide indirect feedback about grammar by using __________, which restructures inaccurate speech into correct form.

• A. fast-mapping
• B. an expansion
• C. overregularization
• D. a recast

Correct answer: D

Rationale: The correct answer is 'a recast.' A recast occurs when an adult rephrases a child's incorrect speech into the accurate form, aiding in the learning of proper grammar. Choice A, 'fast-mapping,' refers to the ability to learn new words quickly; choice B, 'an expansion,' typically involves adding more information to a child's speech; choice C, 'overregularization,' is an error children make when they apply grammatical rules too broadly.

4. In field experiments, researchers __________.

• A. selectively assign participants to treatment conditions in natural settings
• B. cannot use random assignment or manipulate treatment conditions
• C. randomly assign participants to treatment conditions in natural settings
• D. have stronger control over the treatment than in the laboratory

Correct answer: C

Rationale: In field experiments, researchers randomly assign participants to treatment conditions in natural settings. This method allows for a higher level of control over potential confounding variables compared to non-random assignment. Random assignment helps ensure that the groups being compared are comparable at the beginning of the study, which strengthens the internal validity of the research findings. Choice A is incorrect because selective assignment may introduce bias. Choice B is incorrect as researchers can use random assignment in field experiments. Choice D is incorrect because field experiments typically have less control over the treatment compared to laboratory experiments.

5. Maryann is pregnant and works in a smoke-filled environment. What can you tell her about passive smoking?

• A. The negative effects of smoking are only evident in children born to heavy smokers.
• B. Passive smoking is related to low birth weight, infant death, and childhood respiratory illnesses.
• C. Smoke-filled environments are harmful to expectant mothers, but not to their unborn children.
• D. The effects of passive smoking are not yet known.

Correct answer: B

Rationale: Passive smoking, also known as secondhand smoke, can have harmful effects on pregnancies. Research has shown that exposure to smoke-filled environments during pregnancy is linked to low birth weight, infant death, and childhood respiratory illnesses. Pregnant women should avoid exposure to secondhand smoke to protect the health of their unborn babies. Choice A is incorrect because passive smoking affects both the mother and the unborn child, not just children born to heavy smokers. Choice C is incorrect as it underestimates the risks of smoke-filled environments on unborn children. Choice D is incorrect as research has already established the harmful effects of passive smoking on pregnancies.
