1. Where is the site of chemical communication in the brain?

• A. Neuron
• B. Synapse
• C. Axon
• D. Dendrite

Correct answer: B

Rationale: The correct answer is B: Synapse. The synapse is the site where chemical communication occurs between neurons. Neurotransmitters are released from the axon terminal of one neuron, cross the synaptic cleft, and bind to receptors on the dendrites of the next neuron. Choice A, Neuron, is incorrect as it refers to the entire nerve cell. Choices C and D, Axon and Dendrite, are also incorrect as they are specific parts of a neuron and not the primary site of chemical communication.

2. Scientific research has demonstrated that the ________ parenting style is most likely to lead to healthy psychological development in children.

• A. authoritative
• B. authoritarian
• C. permissive
• D. neglectful/uninvolved

Correct answer: A

Rationale: The correct answer is A, authoritative. Authoritative parenting combines warmth and nurturing with reasonable limits and consistent discipline. This style promotes independence, self-regulation, and social competence in children, leading to healthy psychological development. Choice B, authoritarian parenting, is characterized by strict rules and harsh punishment without much warmth, which can lead to anxiety and lower self-esteem in children. Choice C, permissive parenting, involves few demands and little control, resulting in children lacking self-discipline and social skills. Choice D, neglectful/uninvolved parenting, is characterized by a lack of responsiveness to a child's emotional needs and can lead to various negative outcomes such as poor self-esteem and emotional issues.

3. What is the term for a fluid-filled sac in which the baby floats until just before it is born?

• A. Amnion
• B. Placenta
• C. Umbilical cord
• D. Embryo

Correct answer: A

Rationale: The correct answer is A: Amnion. The amnion is a fluid-filled sac that surrounds and protects the developing fetus in the womb. It acts as a cushion, maintaining a stable temperature and protecting the fetus from external pressure. Choices B, C, and D are incorrect because the placenta is an organ that provides nutrients and oxygen to the fetus and removes waste products, the umbilical cord connects the fetus to the placenta to facilitate nutrient exchange, and an embryo is an early stage of development before it becomes a fetus.

4. The four parenting styles described in the text differ along two dimensions: warmth and control. The style associated with the most positive developmental outcome is best described as ________ in warmth and ________ in control.

• A. high; low
• B. low; low
• C. high; moderately high
• D. low; moderately high

Correct answer: C

Rationale: The correct answer is C: 'high in warmth and moderately high in control.' The authoritative parenting style, associated with the most positive developmental outcomes, is characterized by high levels of warmth and support coupled with moderately high levels of control. This balance allows children to develop independence while feeling secure and valued. Choices A, B, and D are incorrect because the authoritative style is not characterized by low warmth or low control, but rather high warmth and moderate control.

5. Which of the following statements is true?

• A. Most behavioral disorders are determined exclusively by genes.
• B. Genes play a role in most mental disorders.
• C. Genes do not affect biochemical processes.
• D. The genes that will be expressed in an individual are not affected by experience.

Correct answer: B

Rationale: The correct answer is B: 'Genes play a role in most mental disorders.' This statement is true as genes do play a significant role in the development of various mental disorders. Choice A is incorrect because most behavioral disorders are influenced by a combination of genetic, environmental, and other factors, not exclusively genes. Choice C is incorrect as genes do affect biochemical processes. Choice D is incorrect because the expression of genes in an individual can be influenced by experiences and environmental factors, a concept known as gene-environment interaction.
