Human Growth and Development Exam 1

Correct Answer: C

Rationale: The first successful intelligence test, the Binet-Simon Scale, was originally developed to identify children with learning problems who required special educational interventions. Choice A is incorrect because measuring individual differences in IQ was not the primary purpose of the test. Choice B is incorrect because documenting age-related improvements in children's intellectual functioning was not the main goal of the test. Choice D is incorrect because comparing the scores of people based on gender, ethnicity, and birth order was not the intended use of the intelligence test.

Correct Answer: B

Rationale: A sequential design permits researchers to check if cohort effects are operating. This design involves combining cross-sectional and longitudinal research, allowing for the comparison of different cohorts at different ages. By using this approach, researchers can determine if developmental changes observed are due to age or generation-specific factors. Therefore, a sequential design is valuable in addressing the potential influence of cohort effects on developmental outcomes. Choices A, C, and D are incorrect because a sequential design does not neglect diversity in developmental outcomes, is not necessarily less efficient than a longitudinal design, and can make both cross-sectional and longitudinal comparisons.

Correct Answer: B

Rationale: Mateo, being born prematurely to a cocaine-addicted mother, is at risk for several health issues. One common effect of prenatal drug exposure is a higher likelihood of sensory and regulatory problems, such as having abnormally shrill and piercing cries. This is a potential outcome that Mateo's caregivers can expect due to his circumstances. Choice A is incorrect as there is no direct correlation between being born prematurely to a cocaine-addicted mother and being very attentive to the environment. Choice C is incorrect as overcoming harmful effects of drug exposure by age 3 is overly optimistic and may not be the case for all children exposed to drugs prenatally. Choice D is incorrect as rapid motor development is not typically associated with prenatal drug exposure.

Correct Answer: C

Rationale: In a structured observation, each participant has an equal opportunity to display the behavior of interest because the researcher designs a specific set of conditions or tasks for all participants to engage in, providing a standardized environment for observation. This allows for fair and equitable observations across all participants, ensuring that each individual has the same opportunities to exhibit the behavior being studied. Choice A, clinical interview, typically involves a one-on-one interaction between a researcher and a participant focusing on collecting information through questions and answers, not providing equal opportunities for behavior display. Choice B, naturalistic observation, involves observing individuals in their natural environment without intervention or manipulation of conditions, which may not always ensure equal opportunities for behavior display. Choice D, case study, focuses on in-depth analysis of a single individual or a small group, providing detailed information but not necessarily ensuring equal opportunities for behavior display among participants.

Correct Answer: C

Rationale: The correct answer is C: longitudinal. In a longitudinal design, participants are followed and studied over an extended period, allowing researchers to observe changes and continuity in development as individuals age. This design is crucial for understanding how individuals grow and change over time. Cross-sectional studies (Choice A) involve comparing different groups at the same time point, while experimental studies (Choice B) involve manipulating variables to observe their effects. Correlational studies (Choice D) examine relationships between variables but do not involve studying participants over time.
