1. An experimental design __________.

• A. allows researchers to gather information in natural life circumstances without altering the participants' experiences
• B. looks at relationships between participants' characteristics and their behavior or development
• C. permits inferences about cause and effect because researchers evenhandedly assign people to treatment conditions
• D. has one major limitation: researchers cannot infer cause and effect

Correct answer: C

Rationale: An experimental design permits inferences about cause and effect because researchers evenhandedly assign people to treatment conditions. This means that researchers can manipulate certain variables and observe the effects on participants, allowing them to determine causation between variables. This is a key strength of experimental research designs. Choices A, B, and D are incorrect because they do not accurately describe the primary purpose or strength of experimental designs. Experimental designs do not focus on gathering information in natural life circumstances (A), looking at relationships between characteristics and behavior (B), or have the limitation of not being able to infer cause and effect (D).

2. Alfred Binet and Theodore Simon __________.

• A. wrote the first book of its time on aging
• B. were among the first to make child development knowledge meaningful to parents
• C. regarded development as a maturational process
• D. constructed the first successful intelligence test Answer: D Page Ref: 14 Skill Level: Remember Topic: Scientific Beginnings Difficulty Level: Moderate

Correct answer: D

Rationale: Alfred Binet and Theodore Simon constructed the first successful intelligence test, known as the Binet-Simon scale, in an effort to measure a child's intelligence level. This test was groundbreaking at the time and laid the foundation for the development of future intelligence tests.

3. According to the lifespan perspective, _______ is supreme in its impact on the life course.

• A. the prenatal period
• B. early childhood
• C. adolescence
• D. no age period

Correct answer: D

Rationale: According to the lifespan perspective, no single period is considered supreme in its impact on the life course. Each stage of life, from prenatal period through adulthood, plays a significant role in shaping an individual's development. Therefore, the correct answer is 'D: no age period.' Choices A, B, and C are incorrect because the lifespan perspective emphasizes that all stages are important and contribute uniquely to an individual's life course.

4. In an investigation of over 120,000 New York City births, babies born even 1 to 2 weeks early __________ than children who experienced a full-length prenatal period.

• A. showed lower reading and math scores at a third-grade follow-up
• B. were less likely to suffer from childhood obesity
• C. were less likely to suffer from neurological impairments
• D. showed higher language and social/emotional scores in early childhood

Correct answer: A

Rationale: In the investigation of over 120,000 New York City births, babies born even 1 to 2 weeks early showed lower reading and math scores at a third-grade follow-up compared to children who experienced a full-length prenatal period. This suggests that being born slightly premature can have an impact on cognitive development, leading to educational challenges later on. Choices B, C, and D are incorrect because the study specifically highlighted lower reading and math scores, not a reduced likelihood of suffering from childhood obesity or neurological impairments, or improved language and social/emotional scores in early childhood.

5. What is the function of the amniotic fluid?

• A. Delivers food and oxygen to the developing organism
• B. Helps keep the temperature of the prenatal world constant
• C. Delivers nutrients and removes waste products
• D. Produces blood cells until the organs are mature enough to take over this function

Correct answer: B

Rationale: The correct answer is B: 'Helps keep the temperature of the prenatal world constant.' Amniotic fluid helps maintain a stable and warm environment for the developing organism, assisting in regulating the temperature. This fluid also acts as a cushion, protecting the fetus from physical harm. Choices A, C, and D are incorrect because while amniotic fluid provides protection and support to the developing organism, it does not directly deliver food, oxygen, nutrients, or remove waste products, nor does it produce blood cells as the organs eventually take over this function.
