Human Growth and Development Final Exam Answers

Correct Answer: B

Rationale: One challenge associated with longitudinal research is that participants may relocate or drop out of the study over time. This can result in missing data and potential biases in the findings, impacting the study's overall validity and reliability. Furthermore, it can present difficulties for researchers in accurately monitoring and analyzing changes in individuals over an extended period. Options A, C, and D are incorrect because longitudinal research can indeed allow for inferences about cause-and-effect relationships, findings can be generalized to the real world with appropriate design and sampling, and it is suitable for studying individual developmental patterns.

Correct Answer: B

Rationale: Evolutionary developmental psychology seeks to understand the adaptive value of species-wide competencies as those competencies change with age. This field focuses on how psychological traits and behaviors have evolved to enhance survival and reproduction over time. It emphasizes the interaction between evolutionary principles and developmental processes to provide insights into human behavior and cognition. Choices A, C, and D are incorrect because they do not accurately describe the primary focus of evolutionary developmental psychology. Choice A is more aligned with cognitive psychology, choice C relates to cognitive science, and choice D could pertain to multidisciplinary approaches but not specifically to evolutionary developmental psychology.

Correct Answer: A

Rationale: The correct answer is A: 5 to 10 minutes. The third stage of labor typically lasts about 5 to 10 minutes. This stage begins after the baby is born and ends when the placenta is delivered. It is the shortest stage of labor compared to the first and second stages. Choice B, 20 to 50 minutes, is incorrect as it is too long for the duration of the third stage. Choice C, 4 to 6 hours, and Choice D, 12 to 14 hours, are also incorrect as they are significantly longer than the actual duration of the third stage of labor.

Correct Answer: B

Rationale: Dr. Dias's research findings indicate a correlation between the death of a spouse and a decline in the surviving partner's physical health. This correlation suggests a relationship between the two variables, but it does not necessarily imply a direct cause-and-effect relationship. Therefore, the correct conclusion supported by this study is option B - 'The death of a spouse is related to a decline in the surviving partner's physical health.' Option A is too direct in its causation claim, which is not proven by correlation alone. Option C reverses the cause and effect relationship suggested by the research. Option D introduces an unrelated third variable, which is not supported by the study's findings.

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.
