The two main types of designs used in all research on human behavior are __________ and __________.
- A. observational; experimental
- B. correlational; experimental
- C. observational; correlational
- D. variable; observational
Correct Answer: B
Rationale: The two main types of designs used in all research on human behavior are correlational and experimental. Correlational research examines the relationship between two or more variables without establishing causation, while experimental research involves manipulating one variable to observe the effect on another variable. These two types of designs are fundamental in understanding and studying human behavior.

During her pregnancy, Padma increased her intake of coffee and tea. Her doctor is likely to tell her that high doses of caffeine contained in coffee and tea increase the risk of __________.
- A. premature labor
- B. limb deformities
- C. respiratory distress at birth
- D. low birth weight
Correct Answer: D
Rationale: High doses of caffeine contained in coffee and tea have been linked to an increased risk of low birth weight. Consuming large amounts of caffeine during pregnancy can interfere with the baby's growth and development, leading to a lower birth weight than expected. It is important for pregnant women to limit their caffeine intake to reduce the risk of complications such as low birth weight.
An ovum bursts from one of a woman's two __________ and is drawn into one of two __________.
- A. ovaries; testes
- B. fallopian tubes; ovaries
- C. corpus luteum; fallopian tubes
- D. ovaries; fallopian tubes
Correct Answer: D
Rationale: An ovum bursts from one of a woman's two ovaries and is drawn into one of two fallopian tubes. This is a correct description of the process of ovulation and fertilization in human reproductive anatomy. The ovaries are responsible for producing and releasing eggs, while the fallopian tubes provide a pathway for the egg to travel to the uterus for potential fertilization.
Which individual is most likely to experience the greatest percentage of REM sleep?
- A. Sammy, a preschool child
- B. Jake, a full-term newborn
- C. Sarah, a teenager
- D. Cheryl, a preterm newborn
Correct Answer: D
Rationale: Preterm newborns, like Cheryl, experience a higher percentage of REM sleep compared to full-term newborns. This is because REM sleep plays a critical role in brain development, and preterm infants have an increased need for brain development due to their early arrival. Therefore, Cheryl, as a preterm newborn, is most likely to experience the greatest percentage of REM sleep among the individuals listed.
The clinical method __________.
- A. allows investigators to see directly the everyday behaviors they hope to explain
- B. must be conducted with large groups of people at the same time
- C. provides little information on how children and adults actually behave
- D. yields richly detailed case narratives that offer valuable insights
Correct Answer: D
Rationale: The clinical method yields richly detailed case narratives that offer valuable insights. This method involves in-depth interviews, direct observation, and structured interactions to gather detailed information about an individual's behavior and development. It focuses on understanding the unique aspects of an individual's experience and can provide rich insights into behavior and development.
