1. Prenatally malnourished babies frequently __________.
- A. reject breast milk
- B. have enlarged hearts
- C. catch respiratory illnesses
- D. have a higher-than-average birth weight
Correct answer: C
Rationale: Prenatally malnourished babies frequently catch respiratory illnesses. Malnourished babies have weakened immune systems, making them more susceptible to illnesses such as respiratory infections. This is a common consequence that is observed in babies who did not receive adequate nutrition during the prenatal period. Choices A, B, and D are incorrect. While malnourished babies may have feeding challenges, rejecting breast milk is not a common consequence. Enlarged hearts are not typically associated with prenatal malnutrition, and having a higher-than-average birth weight is unlikely in malnourished babies.
2. 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.
- A. clinical interview
- B. naturalistic observation
- C. structured observation
- D. case study
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.
3. Nonnormative influences are irregular and do not follow a predictable timetable.
- A. Nonnormative
- B. History-graded
- C. Age-graded
- D. Bio-historical
Correct answer: A
Rationale: The correct answer is A: Nonnormative. Nonnormative influences are events or experiences that are irregular and unique to the individual, so they do not follow a predictable timetable. These influences can include major life events like winning the lottery or experiencing a natural disaster, and they have a significant impact on a person's development. Choice B, History-graded influences, are events that are common to people of a particular generation due to historical circumstances. Choice C, Age-graded influences, are events that are typical for people of a certain age group. Choice D, Bio-historical, is not a recognized term in developmental psychology.
4. 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.
5. A 20-week-old fetus can __________.
- A. be stimulated as well as irritated by sounds
- B. survive, if born early
- C. breathe without oxygen assistance, if born early
- D. control its own body temperature Answer: A Page Ref: 80 Skill Level: Understand Topic: Prenatal Development Difficulty Level: Moderate
Correct answer: A
Rationale: A 20-week-old fetus is able to be stimulated as well as irritated by sounds because by this stage of prenatal development, the fetus's auditory system is already well-developed. It can respond to external sounds and may even startle or move in reaction to loud noises.
