Human Growth and Development Final Exam Answers
1. Central to Piaget's theory is the concept of __________.
- A. imitation
- B. adaptation
- C. self-efficacy
- D. scaffolding
Correct answer: B
Rationale: Central to Piaget's theory is the concept of adaptation, which refers to the process by which individuals adjust to new information and experiences by modifying their existing cognitive structures. Piaget believed that this process of adaptation involved two key components: assimilation, where individuals incorporate new information into their existing schemas, and accommodation, where individuals adjust their schemas to fit new information. This concept highlights the dynamic nature of cognitive development and the importance of interaction between individuals and their environment in shaping intellectual growth. Choice A, 'imitation,' is incorrect as Piaget's theory focuses on how individuals actively construct their understanding of the world through their interactions with it, rather than simply imitating others. Choice C, 'self-efficacy,' is not the central concept in Piaget's theory; self-efficacy is a concept from Bandura's social cognitive theory. Choice D, 'scaffolding,' is associated with Vygotsky's sociocultural theory, not Piaget's theory.
2. In an experiment, the independent variable __________.
- A. is the one the investigator expects to be influenced by another variable
- B. is the one the investigator expects to cause changes in another variable
- C. cannot be manipulated or controlled by the researcher
- D. is the number that describes how two measures are associated with each other
Correct answer: B
Rationale: In an experiment, the independent variable is the one that the investigator expects to cause changes in another variable. It is the factor that is deliberately manipulated or changed by the researcher to observe its effects on the dependent variable. The purpose of manipulating the independent variable is to study its impact on the outcome, allowing researchers to establish cause-and-effect relationships in their investigations. Choice A is incorrect because the independent variable is not influenced but rather influences another variable. Choice C is incorrect as the independent variable is intentionally manipulated by the researcher. Choice D is incorrect as it refers to a different concept unrelated to the independent variable in an experiment.
3. Lanugo ________.
- A. permits food and oxygen to reach the organism
- B. provides the fetus a cushion against jolts caused by the mother's movements
- C. helps regulate the fetus's body temperature
- D. helps the vernix stick to the skin
Correct answer: D
Rationale: Lanugo helps the vernix stick to the skin. Vernix is a waxy substance that covers the fetus's skin during pregnancy. Lanugo is a fine, downy hair that helps to anchor the vernix to the skin, providing protection and nourishment to the developing fetus. Choices A, B, and C are incorrect as they do not accurately describe the role of lanugo in prenatal development.
4. Which major theory of human development emphasizes plasticity at all ages?
- A. psychoanalytic perspective
- B. ethology
- C. evolutionary developmental psychology
- D. lifespan perspective
Correct answer: D
Rationale: The correct answer is D, the lifespan perspective. This perspective underscores the idea that individuals have the capacity for growth and change at any age, highlighting plasticity throughout the lifespan. It acknowledges the continuous development and adaptability of individuals to various experiences and factors. Choice A, the psychoanalytic perspective, focuses more on unconscious processes and early childhood experiences. Choice B, ethology, emphasizes the study of animal behavior in natural environments. Choice C, evolutionary developmental psychology, examines how evolutionary principles influence human development but does not specifically focus on plasticity at all ages.
5. In ecological systems theory, how does Toby's move just before entering fourth grade represent a significant change in his life?
- A. Microsystem
- B. Mesosystem
- C. Exosystem
- D. Chronosystem
Correct answer: D
Rationale: In ecological systems theory, the chronosystem refers to the dimension of time and how events and transitions over time can influence an individual's development. Toby's move just before entering fourth grade represents a significant change in his life that falls under the chronosystem. The microsystem involves the immediate environments and relationships that directly influence an individual, the mesosystem relates to connections between these environments, and the exosystem includes external settings that indirectly influence the individual, such as parents' workplaces. Therefore, Toby's move best exemplifies a change in the chronosystem due to the temporal influence on his development.
