Bernadette, a participant in a longitudinal study, became quite familiar with the test over time and, as a result, her performance improved. This limitation of longitudinal research is known as __________.
- A. biased sampling
- B. practice effects
- C. random assignment
- D. cohort effects
Correct Answer: B
Rationale: Practice effects refer to the phenomenon where participants in a longitudinal study show improvement in test performance over time due to becoming familiar with the tasks or test materials. This can be considered a limitation as it may distort the results by showing an artificial improvement rather than a true developmental change.

Increasingly, researchers __________.
- A. assume that development stops at adolescence
- B. view old age as a period of decline
- C. view heredity as more influential than the environment
- D. see development as a perpetually ongoing process
Correct Answer: D
Rationale: Increasingly, researchers see development as a perpetually ongoing process.

Researchers now focus on understanding how individuals change and grow over time, recognizing that development is a lifelong journey influenced by both biological and environmental factors.
During her labor, Renee asks for a mild dose of painkillers to help her relax. Renee will probably be given __________.
- A. an anesthetic
- B. an analgesic
- C. folic acid
- D. an anti-inflammatory medication
Correct Answer: B
Rationale: Renee will likely be given an analgesic during her labor to help manage her pain and provide relaxation.

Dr. Whiren studies how culture is transmitted to the next generation. Dr. Whiren's research best aligns with the perspective of which theorist?
- A. Jean Piaget
- B. John Bowlby

- D. Erik Erikson
Correct Answer: C
Rationale: Dr. Whiren's study on how culture is transmitted to the next generation aligns best with the perspective of Lev Vygotsky.

He believed that children learn through interactions with others and that culture plays a significant role in this learning process.
Which statement describes a limitation of the clinical method?
- A. It may not yield observations typical of participants' behavior in everyday life.
- B. Researchers cannot control conditions under which participants are observed.
- C. The findings cannot be applied to individuals other than the participant.
- D. It does not usually yield rich, descriptive insights into factors that affect development.
Correct Answer: C
Rationale: The statement that describes a limitation of the clinical method is that the findings cannot be applied to individuals other than the participant. The clinical method typically involves in-depth studies of individual participants, which may limit generalizability to a broader population. This means that the findings from a clinical study may not be applicable to other individuals who are not directly involved in the study.
