Human Growth and Development Final Exam
1. In the __________ period, teratogens rarely have any impact.
- A. germinal
- B. embryonic
- C. fetal
- D. prenatal
Correct answer: A
Rationale: In the germinal period of prenatal development, which lasts for about the first two weeks after fertilization, the developing organism is a zygote that has not yet implanted in the uterus. During this period, teratogens rarely have any impact because essential implantation and early cellular division processes are occurring. Teratogens are more likely to have significant effects during the later embryonic and fetal periods of development. Therefore, the correct answer is A. Choice B, embryonic period, is incorrect because teratogens have a higher likelihood of impacting development during this period. Choice C, fetal period, is also incorrect as teratogens can impact development during this stage as well. Choice D, prenatal, is a broad term encompassing the entire period of development from conception to birth and is not a specific developmental stage where teratogens have a minimal impact.
2. Although Justin spent his first 18 months in an orphanage, his adoptive mother believes that sensitive caregiving will help Justin overcome his early experiences. Justin's mother emphasizes the role of __________ in development.
- A. nurture
- B. stages
- C. stability
- D. nature
Correct answer: A
Rationale: The correct answer is A, nurture. Nurture refers to the environmental influences that shape behavior and development. In this scenario, Justin's adoptive mother believes that providing sensitive caregiving will override the negative effects of his early experiences in the orphanage, highlighting the importance of nurture in promoting healthy development. Choice B, stages, is incorrect as it refers to the sequence of developmental milestones individuals pass through. Choice C, stability, is incorrect as it pertains to the consistency of behavior or development over time. Choice D, nature, is incorrect as it relates to genetic and biological factors influencing development, which is not the focus of Justin's mother's beliefs.
3. 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.
4. According to Jean Piaget's cognitive-developmental theory, __________?
- A. children actively construct knowledge as they manipulate and explore their world
- B. children's learning depends on reinforcers, such as rewards from adults
- C. adult teaching is the best way to foster development
- D. rapid development occurs during sensitive periods
Correct answer: A
Rationale: According to Jean Piaget's cognitive-developmental theory, children actively construct knowledge as they manipulate and explore their world. Piaget emphasized that children learn through their own actions and interactions with the environment, leading to cognitive development. Choice B is incorrect because Piaget's theory focuses on children's active engagement in learning rather than passive reinforcement. Choice C is incorrect because Piaget's theory highlights the child's role in constructing knowledge, not solely relying on adult teaching. Choice D is incorrect as it refers to sensitive periods, a concept more associated with other developmental theories like Erikson's psychosocial theory, not Piaget's cognitive-developmental theory.
5. The embryonic disk __________.
- A. becomes the new organism
- B. is the outer ring of cells on a blastocyst
- C. has a good chance of survival outside the womb
- D. is a protective membrane that surrounds the amnion Answer: A Page Ref: 77 Skill Level: Understand Topic: Prenatal Development Difficulty Level: Moderate
Correct answer: A
Rationale: The embryonic disk becomes the new organism. It is a cluster of cells within the blastocyst that will develop into the fetus during the early stages of prenatal development. This cluster of cells is responsible for giving rise to all the tissues and organs of the developing organism.
