1. The yolk sac __________.

• A. forms during the third trimester of pregnancy
• B. is the outer ring of cells that surrounds the blastocyst Copyright © 2018 Laura E. Berk. All Rights Reserved. 3 Test Bank for Berk, Development Through the Lifespan, 7e
• C. produces blood cells until the organs are mature enough to take over this function
• D. contains one large vein that delivers blood loaded with nutrients and two arteries that remove waste Answer: C Page Ref: 77 Skill Level: Understand Topic: Prenatal Development Difficulty Level: Moderate

Correct answer: C

Rationale: The yolk sac is an extraembryonic membrane that plays a significant role in the early development of the embryo. One of its functions is to produce blood cells until the organs are mature enough to take over this function. This process occurs during the early stages of prenatal development to support the growing embryo before it can sustain itself independently.

2. When faced with a problem, Sydney starts with a hypothesis, deduces testable inferences, and isolates and combines variables to see which inferences are confirmed. Sydney is in Piaget's __________ stage of development.

• A. sensorimotor
• B. preoperational
• C. concrete operational
• D. formal operational

Correct answer: D

Rationale: Sydney's approach of starting with a hypothesis, deducing testable inferences, and isolating and combining variables to confirm inferences aligns with the characteristics of the formal operational stage in Piaget's theory of cognitive development. This stage typically emerges during adolescence and is characterized by advanced logical thinking, abstract reasoning, and the ability to think systematically about all possible outcomes of a problem. Choice A, sensorimotor, is incorrect as it pertains to the stage where infants learn through sensory experiences and motor actions. Choice B, preoperational, is incorrect as it involves egocentrism and lack of conservation. Choice C, concrete operational, is incorrect as it focuses on operational thought and logical reasoning in concrete contexts.

3. Nonnormative influences are irregular and do not follow a predictable timetable.

• A. Nonnormative
• B. History-graded
• C. Age-graded
• D. Bio-historical

Correct answer: A

Rationale: The correct answer is A: Nonnormative. Nonnormative influences are events or experiences that are irregular and unique to the individual, so they do not follow a predictable timetable. These influences can include major life events like winning the lottery or experiencing a natural disaster, and they have a significant impact on a person's development. Choice B, History-graded influences, are events that are common to people of a particular generation due to historical circumstances. Choice C, Age-graded influences, are events that are typical for people of a certain age group. Choice D, Bio-historical, is not a recognized term in developmental psychology.

4. Dr. Redmund characterizes his view of development as a bioecological model. His perspective is aligned with that of which theorist?

• A. Jean Piaget
• B. Urie Bronfenbrenner
• C. Lev Vygotsky
• D. Niko Tinbergen

Correct answer: B

Rationale: Dr. Redmund's view of development aligns with the bioecological model, which is associated with Urie Bronfenbrenner. This model emphasizes the interaction between an individual's biological characteristics and environmental influences in development. Jean Piaget's theory focuses on cognitive development, Lev Vygotsky's theory emphasizes social interactions, and Niko Tinbergen is known for his work in animal behavior and instinct, not human development. Therefore, the correct answer is Urie Bronfenbrenner (Choice B).

5. When __________, newborn Takeo's toes should fan out and curl as his foot twists in.

• A. a bright light shines in his eyes
• B. his bare foot touches a flat surface
• C. his cheek is stroked near the corner of his mouth
• D. the sole of his foot is stroked from toe to heel

Correct answer: D

Rationale: The correct answer is D because the description of the twisting and fanning out of newborn Takeo's toes suggests the Babinski reflex, which is typically elicited by stroking the sole of the foot from toe to heel. The Babinski reflex is a normal response in newborns and indicates proper neurological development. Choices A, B, and C are incorrect as they do not elicit the specific response described in the question.
