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. Today, Albert Bandura's theory stresses the importance of __________.
- A. behavior modification
- B. punishment
- C. cognition
- D. reinforcement
Correct answer: C
Rationale: Albert Bandura's theory emphasizes the role of cognition in learning through observation. It highlights the significance of mental processes such as attention, memory, and motivation in shaping behavior. Choice A, behavior modification, focuses more on changing specific behaviors through various techniques. Choice B, punishment, involves the application of negative consequences to reduce the likelihood of a behavior occurring. Choice D, reinforcement, centers on the use of rewards or punishments to increase or decrease the probability of a behavior.
3. Mounting evidence suggests that __________ is a major contributor to SIDS.
- A. impaired brain functioning
- B. higher-than-average birth weight
- C. organized and patterned sleep behavior
- D. a family history of chromosomal abnormalities
Correct answer: A
Rationale: Impaired brain functioning is a major contributor to Sudden Infant Death Syndrome (SIDS). Research has shown that abnormalities in the brainstem, which controls automatic functions like breathing and heart rate, can play a role in SIDS cases. As such, mounting evidence suggests that compromised brain functioning is a significant factor in the occurrence of SIDS. Choices B, C, and D are incorrect. Higher-than-average birth weight, organized and patterned sleep behavior, and a family history of chromosomal abnormalities are not identified as major contributors to SIDS according to the provided information.
4. Baby Azeez's limb movements are gentle. He stirs occasionally, and facial grimacing occurs. Although his eyelids are closed, occasional rapid eye movements can be seen beneath them. Azeez is most likely in which state?
- A. regular sleep
- B. drowsiness
- C. irregular sleep
- D. quiet alertness
Correct answer: C
Rationale: The description of Baby Azeez's behavior matches the characteristics of irregular sleep in a newborn. During irregular sleep, limb movements are gentle, occasional facial grimacing occurs, and rapid eye movements can be seen beneath closed eyelids. This state is also known as active sleep and is associated with dreaming in newborns. Choice A, regular sleep, is incorrect as the described behaviors are not typical of this state. Choice B, drowsiness, does not match the active movements and facial grimacing observed in Azeez. Choice D, quiet alertness, is also incorrect as it does not align with the described behaviors of limb movements, facial grimacing, and rapid eye movements.
5. Who is generally regarded as the founder of the child study movement?
- A. Arnold Gesell was among the first to write child-rearing books for parents
- B. Arnold Gesell is generally regarded as the founder of the child study movement
- C. Arnold Gesell foreshadowed lifespan research by writing a book on aging
- D. Arnold Gesell constructed the first successful intelligence test
Correct answer: B
Rationale: Arnold Gesell is generally regarded as the founder of the child study movement, emphasizing the importance of observing and documenting children's behaviors to understand their development. While he was a significant figure in child development research, he did not specifically write child-rearing books for parents, foreshadow lifespan research, or construct the first successful intelligence test. Choice A is incorrect as Gesell's focus was more on research rather than writing child-rearing books. Choice C is incorrect as Gesell's main contributions were in child development, not specifically in aging research. Choice D is incorrect as Gesell is not credited with constructing the first successful intelligence test.
