Dr. Bigelow is interested in studying musical prodigies. Which method is best suited for this type of research?

  • A. naturalistic observation
  • B. clinical interview
  • C. case study
  • D. structured interview
Correct Answer: C

Rationale: A case study would be the best method for Dr. Bigelow to study musical prodigies. In a case study, the researcher can closely examine and analyze the unique characteristics, abilities, and behaviors of individual subjects. This method allows for in-depth exploration of a specific phenomenon, making it ideal for investigating exceptional cases such as musical prodigies. Naturalistic observation involves observing subjects in their natural environment without interference, which may not provide the detailed insights needed for studying musical prodigies. Clinical interviews focus on gathering information through structured questioning, not ideal for studying unique talents. Structured interviews involve asking a set of predetermined questions, which may not allow for the depth of exploration required for studying musical prodigies.

The third stage of labor lasts about __________.

  • A. 5 to 10 minutes
  • B. 20 to 50 minutes
  • C. 4 to 6 hours
  • D. 12 to 14 hours
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.

The information-processing approach views the human mind as a __________.

  • A. socially mediated process
  • B. collection of stimuli and responses
  • C. system of genetically programmed behaviors
  • D. symbol-manipulating system through which information flows
Correct Answer: D

Rationale: The information-processing approach views the human mind as a symbol-manipulating system through which information flows. This perspective emphasizes how information is received, processed, stored, and retrieved in the mind, similar to how a computer processes data through symbols and operations. Choices A, B, and C are incorrect because they do not align with the fundamental principles of the information-processing approach, which focuses on the mind's symbolic manipulation of information rather than being a socially mediated process, a collection of stimuli and responses, or a system of genetically programmed behaviors.

Babies who spend more time alert are likely to have __________.

  • A. parents who feel incompetent
  • B. a slight advantage in mental development
  • C. a big disadvantage in social development
  • D. parents who must exert great effort to soothe them
Correct Answer: B

Rationale: Babies who spend more time alert are likely to have a slight advantage in mental development. Being alert allows babies to engage with their surroundings, explore, and learn, which can contribute to their cognitive development. This is different from social development, which is more related to interactions with others, and not necessarily impacted by the amount of alertness a baby displays. Choices A, C, and D are incorrect because there is no direct correlation between a baby's alertness and their parents' feelings of incompetence, a big disadvantage in social development, or the effort parents need to soothe them.

Mounting evidence suggests that __________ is a major contributor to SIDS.

  • A. impaired brain functioning
  • B. higher-than-average birth weight
  • C. organized and patterned sleep behavior
  • D. a family history of chromosomal abnormalities
Correct Answer: A

Rationale: Impaired brain functioning is a major contributor to Sudden Infant Death Syndrome (SIDS). Research has shown that abnormalities in the brainstem, which controls automatic functions like breathing and heart rate, can play a role in SIDS cases. As such, mounting evidence suggests that compromised brain functioning is a significant factor in the occurrence of SIDS. Choices B, C, and D are incorrect. Higher-than-average birth weight, organized and patterned sleep behavior, and a family history of chromosomal abnormalities are not identified as major contributors to SIDS according to the provided information.

During prenatal development, the ectoderm becomes the __________.

  • A. muscles and skeleton
  • B. nervous system and skin
  • C. circulatory system and other internal organs
  • D. digestive system, lungs, urinary tract, and glands
Correct Answer: B

Rationale: The correct answer is B: nervous system and skin. The nervous system, which includes the brain, spinal cord, and nerves, as well as the skin, develop from the ectoderm layer of cells during prenatal development. Choice A is incorrect because muscles and skeleton develop from mesoderm. Choice C is incorrect because the circulatory system and other internal organs develop from mesoderm and endoderm. Choice D is incorrect because the digestive system, lungs, urinary tract, and glands develop from endoderm.
