Human Growth and Development Final Exam Answers
1. The more alcohol a woman consumes during pregnancy, the __________.
- A. higher the birth weight of the child
- B. greater the likelihood of ARND instead of FAS or p-FAS
- C. poorer the child's achievement scores in the school years
- D. greater the child's speed of information processing
Correct answer: C
Rationale: The correct answer is C: 'poorer the child's achievement scores in the school years.' Prenatal exposure to alcohol has been linked to a range of cognitive and behavioral difficulties, including lower academic achievement in children. These difficulties may manifest as poor achievement scores in later school years. Choices A, B, and D are incorrect because alcohol consumption during pregnancy is not associated with higher birth weight of the child, the likelihood of ARND instead of FAS or p-FAS, or greater speed of information processing in the child.
2. Newborn infants who are brain damaged or who have experienced birth trauma often __________.
- A. display disturbed REM-NREM sleep cycles
- B. cry less than those with no brain functioning problems
- C. spend about 20 percent of their total sleep time in REM sleep
- D. have very low or inaudible cries
Correct answer: A
Rationale: Newborn infants who are brain damaged or who have experienced birth trauma often display disturbed REM-NREM sleep cycles. This disruption in the sleep cycle can be a sign of neurological issues and can impact the newborn's overall health and development. Choice B is incorrect because infants with brain damage or birth trauma may actually cry more due to their discomfort or neurological issues. Choice C is incorrect because spending about 20 percent of total sleep time in REM sleep is not necessarily specific to brain-damaged or birth-traumatized infants. Choice D is incorrect because having very low or inaudible cries is not a common characteristic associated with brain damage or birth trauma in infants.
3. Jalynn is in the last half of the first month of her pregnancy. Which of the following is developing the fastest?
- A. circulatory system
- B. endocrine system
- C. nervous system
- D. skin
Correct answer: C
Rationale: During the last half of the first month of pregnancy, the nervous system develops the fastest among the options provided. This rapid development of the nervous system is crucial for the overall growth and functioning of the fetus. The nervous system includes the brain and spinal cord, which are essential for various bodily functions and will continue to develop throughout the pregnancy. The circulatory system, although important, does not develop at the fastest rate during this stage. The endocrine system and skin also play significant roles in the development of the fetus but are not the systems that develop the fastest in the last half of the first month of pregnancy.
4. Jade spent two years in a Mexican-American community studying communication between parents and children. Jade was using __________.
- A. naturalistic observation
- B. ethnography
- C. self-reports
- D. structured observation
Correct answer: B
Rationale: Jade was using ethnography. Ethnography involves the systematic study of people and cultures through participant observation and interviews. In this case, Jade spent two years in a Mexican-American community studying communication between parents and children, which aligns with the methodology of ethnography. Ethnography allows researchers to gain an in-depth understanding of a particular cultural group's behaviors, practices, and beliefs. Choice A, naturalistic observation, involves observing subjects in their natural environment without interference or manipulation. While similar to ethnography in some aspects, naturalistic observation does not typically involve the same level of cultural immersion and participant interaction as ethnography. Choice C, self-reports, refers to data collected directly from participants about their thoughts, feelings, or behaviors. This method relies on participants' subjective responses and may not provide the same depth of cultural insights as ethnography. Choice D, structured observation, involves observing behavior in a structured and controlled environment. Unlike ethnography, structured observation does not focus on the cultural nuances and immersive study of a specific community.
5. In a correlational design, researchers __________.
- A. gather information on individuals without altering their experiences
- B. divide events and behaviors of interest into two types: dependent and independent variables
- C. use an evenhanded procedure to assign people to two or more treatment conditions
- D. directly control or manipulate changes in the independent variable
Correct answer: A
Rationale: In a correlational design, researchers gather information on individuals without altering their experiences. Correlational studies examine the relationship between two or more variables without any manipulation or control by the researchers. The researchers simply observe and measure the variables of interest without intervening in any way. Choices B, C, and D are incorrect because they describe aspects related to experimental designs rather than correlational designs. In an experimental design, researchers manipulate variables, assign participants to different treatment conditions, and control changes in the independent variable, which is not the case in correlational studies.
