Human Growth and Development Final Exam Answers
1. Like longitudinal research, cross-sectional studies can be threatened by __________.
- A. practice effects
- B. participant dropout
- C. sequential timing
- D. cohort effects
Correct answer: D
Rationale: Cross-sectional studies can be threatened by cohort effects because different age groups may have experienced different historical or social contexts, influencing the results. This disparity can lead to invalid comparisons between age groups, confounding the study's findings. Option A, practice effects, refer to changes in participants' behavior due to repeated testing, not a specific threat to cross-sectional studies. Participant dropout (Option B) is a threat related to attrition in longitudinal studies, not cross-sectional studies. Sequential timing (Option C) does not pose a threat to cross-sectional studies; instead, it refers to the order of tasks in a study design.
2. Kathryn would like to give birth in a medical facility that permits maternal control over labor and delivery, including choice of delivery positions, and allows the presence of family members and friends. Kathryn should consider giving birth at a __________.
- A. private home
- B. local hospital
- C. doula center
- D. freestanding birth center
Correct answer: D
Rationale: Kathryn should consider giving birth at a freestanding birth center. Freestanding birth centers provide a setting where women can have more control over their labor and delivery experience, including the choice of delivery positions, the presence of family members and friends, and involvement in decision-making throughout the process. These centers offer a more home-like environment compared to hospitals while still providing access to medical support if needed. Choices A (private home) and B (local hospital) do not necessarily guarantee the level of control and facilities Kathryn seeks. While a doula center (Choice C) can provide additional support during labor, it may not offer the same level of medical facilities and control over the birthing process as a freestanding birth center.
3. Dr. George predicted that positive reinforcement would increase prosocial behavior in preschoolers. Dr. George's prediction is an example of a __________.
- A. theory
- B. research question
- C. hypothesis
- D. research design
Correct answer: C
Rationale: Dr. George's prediction that positive reinforcement would increase prosocial behavior in preschoolers is an example of a hypothesis. A hypothesis is a specific, testable prediction about the relationship between variables based on existing knowledge or theories. In this case, Dr. George is making a prediction about the effect of positive reinforcement on prosocial behavior, which can be tested through research. Choice A, 'theory,' is incorrect because a theory is a broader explanation that integrates a range of findings and observations. Choice B, 'research question,' is incorrect as it refers to an inquiry that asks about the relationship between variables but lacks the specificity and testability of a hypothesis. Choice D, 'research design,' is incorrect as it pertains to the overall strategy or plan for conducting a research study, not the specific prediction Dr. George made.
4. The lifespan perspective on human development assumes that development is __________.
- A. static and stable
- B. multidimensional and multidirectional
- C. continuous, rather than discontinuous
- D. largely the result of heredity
Correct answer: B
Rationale: The lifespan perspective on human development assumes that development is multidimensional and multidirectional. This means that development occurs in various domains (such as physical, cognitive, and psychosocial) and can involve gains and losses as individuals age. This perspective recognizes that human development is complex and dynamic, involving various factors and pathways over the course of a person's life. Choices A, C, and D are incorrect because human development is not static and stable (A), can involve both continuous and discontinuous changes (C), and is influenced by a combination of heredity and environment rather than solely by heredity (D).
5. If learning has occurred in classical conditioning, and the neutral stimulus by itself produces a response similar to the reflexive response, the neutral stimulus is then called a __________.
- A. neutral response
- B. conditioned stimulus
- C. conditioned response
- D. reinforcer
Correct answer: B
Rationale: In classical conditioning, when a neutral stimulus triggers the reflexive response, it becomes a conditioned stimulus. Therefore, the correct term for the neutral stimulus that now elicits a response is a conditioned stimulus. Choices A, C, and D are incorrect: A neutral response is not a standard term in classical conditioning; a conditioned response is the learned response to the conditioned stimulus, not the neutral stimulus itself; a reinforcer is a stimulus that follows a behavior and increases the likelihood of that behavior happening again, which is not the same as a conditioned stimulus.
