Human Growth and Development Final Exam Answers
1. During the second month of pregnancy, __________.
- A. the umbilical cord first appears as a primitive body stalk
- B. touch sensitivity extends to most of the body
- C. the heart develops separate chambers
- D. the heartbeat can be heard through a stethoscope
Correct answer: C
Rationale: During the second month of pregnancy, the heart of the developing fetus begins to develop separate chambers, forming the structure necessary for a fully functioning heart. This is a significant milestone in the prenatal development process. Choices A, B, and D are incorrect because the appearance of the umbilical cord as a primitive body stalk typically occurs around week 5-6, touch sensitivity extending to most of the body is more characteristic of the end of the second trimester, and the heartbeat is usually detectable through a stethoscope around the 18th to 20th week of pregnancy, not during the second month.
2. According to __________ theory, children learn primarily through modeling.
- A. reinforcement
- B. operant conditioning
- C. social learning
- D. classical conditioning
Correct answer: C
Rationale: According to social learning theory, children primarily learn through modeling, observation, and imitation of others. This theory emphasizes the importance of cognitive processes in learning, as opposed to only focusing on direct reinforcement or punishment. Social learning theory was developed by psychologist Albert Bandura and is a key theory in the field of child development. Choice A, reinforcement, is incorrect as it refers to the process of strengthening a behavior through rewards or punishments. Choice B, operant conditioning, is also incorrect as it is a learning process that involves reinforcement and punishment to shape behavior. Choice D, classical conditioning, is not the correct answer as it involves learning through association between stimuli.
3. Self-reports __________.
- A. use a flexible, conversational style to probe for the participant's point of view
- B. describe the entire stream of behavior—everything said and done over a certain time period
- C. range from relatively unstructured interviews to highly structured interviews, questionnaires, and tests
- D. bring together a wide range of information on one person, including interviews, observations, and test scores
Correct answer: C
Rationale: Self-reports can range from relatively unstructured interviews to highly structured interviews, questionnaires, and tests. This variety allows researchers to collect information from participants in different ways, depending on the research goals and the type of information being sought. Choices A, B, and D are incorrect because they do not accurately describe the range and flexibility of self-reports as outlined in the field of research methodology.
4. In the information-processing system, where does information first enter?
- A. central executive
- B. short-term memory store
- C. sensory register
- D. long-term memory store
Correct answer: C
Rationale: In the information-processing system, information first enters the sensory register. This is where sensory information from the environment is briefly stored before being processed further. The central executive is responsible for coordinating cognitive processes, the short-term memory store holds information temporarily for immediate tasks, and the long-term memory store stores information for long periods, but the sensory register is the initial entry point for incoming information.
5. __________ doubles the risk of SIDS.
- A. Failure to tightly swaddle an infant during sleep
- B. Use of a pacifier or a security blanket
- C. Placing an infant to sleep on his back
- D. Cigarette smoking by a caregiver Answer: D Page Ref: 106 Box: BIOLOGY AND ENVIRONMENT: The Mysterious Tragedy of Sudden Infant Death Syndrome Skill Level: Understand Topic: The Newborn Baby’s Capacities Difficulty Level: Moderate
Correct answer: D
Rationale: Cigarette smoking by a caregiver doubles the risk of SIDS. Secondhand smoke exposure can increase the likelihood of SIDS due to the toxins and chemicals present in cigarette smoke. It is important to have a smoke-free environment for infants to reduce the risk of SIDS.
