Human Growth and Development Final Exam Answers
1. Theorists who emphasize plasticity believe that __________.
- A. change in response to influential experiences is possible
- B. heredity, rather than the environment, influences behavior
- C. individuals who are high in anxiety as children will remain so at later ages
- D. early experiences establish a lifelong pattern of behavior
Correct answer: A
Rationale: Theorists who emphasize plasticity believe that change in response to influential experiences is possible. They argue that individuals have the capacity to adapt and change their behavior based on their experiences, rather than being limited by genetic predispositions or early childhood experiences. This perspective highlights the importance of environmental influences in shaping behavior and development. Choices B, C, and D are incorrect because they do not align with the concept of plasticity, which emphasizes the flexibility and adaptability of individuals in response to their experiences, rather than being fixed by heredity, childhood traits, or early experiences.
2. Longitudinal research can identify common patterns as well as individual differences in development because the investigator __________.
- A. studies groups of participants differing in age at the same point in time
- B. randomly assigns participants to treatment conditions
- C. tracks the performance of each person over time
- D. conducts quasi-experiments, comparing conditions that already exist
Correct answer: C
Rationale: Longitudinal research involves tracking the performance of each person over time. By doing so, researchers can observe common patterns in development among a group of individuals and also identify individual differences in how each person progresses over time. This methodology allows researchers to gather data on the same individuals repeatedly, offering insights into how development unfolds over the lifespan. Choices A, B, and D are incorrect because longitudinal research focuses on observing individuals over time rather than studying groups at a single point, randomly assigning participants to treatments, or conducting quasi-experiments.
3. During Irina's first week of pregnancy, __________.
- A. heart muscles begin to develop
- B. the zygote multiplies and forms a blastocyst
- C. a primitive brain and spinal cord appear
- D. the embryo can move
Correct answer: B
Rationale: During the first week of pregnancy, the zygote (fertilized egg) undergoes rapid cell divisions and forms a blastocyst. This is a crucial stage where the cells differentiate and specialize, setting the foundation for the development of the embryo. It is during this time that the zygote implants itself into the uterine wall, initiating the process of pregnancy. Choices A, C, and D are incorrect because during the first week of pregnancy, the focus is on the initial development and multiplication of the zygote, not on the development of heart muscles, a primitive brain and spinal cord, or the embryo's ability to move.
4. Many theorists believe that behaviorism and social learning theory ________.
- A. overemphasize the plasticity of cognitive development
- B. overestimate people's contributions to their own development
- C. offer too narrow a view of important environmental influences
- D. overemphasize each individual's unique life history
Correct answer: C
Rationale: Many theorists believe that behaviorism and social learning theory offer too narrow a view of important environmental influences. This is because they focus mainly on observable behaviors and external factors, neglecting the role of internal cognitive processes and individual differences in shaping development. Choices A, B, and D are incorrect because behaviorism and social learning theory do not specifically emphasize the plasticity of cognitive development, overestimate people's contributions to their own development, or overemphasize each individual's unique life history. Instead, they are criticized for providing a limited perspective by focusing predominantly on external stimuli and behaviors.
5. 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).
