Human Growth and Development Final Exam Answers
1. __________ increases tenfold from the twentieth week until birth.
- A. Amniotic fluid
- B. Brain weight
- C. Fetal length
- D. Neuron production
Correct answer: B
Rationale: Brain weight increases tenfold from the twentieth week until birth. This rapid growth and development of the brain during the prenatal period is crucial for setting the foundation for future cognitive and neurological functions. Choices A, C, and D are incorrect because although they also undergo changes during prenatal development, none of them increase tenfold from the twentieth week until birth, unlike brain weight.
2. Prenatally malnourished babies frequently __________.
- A. reject breast milk
- B. have enlarged hearts
- C. catch respiratory illnesses
- D. have a higher-than-average birth weight
Correct answer: C
Rationale: Prenatally malnourished babies frequently catch respiratory illnesses. Malnourished babies have weakened immune systems, making them more susceptible to illnesses such as respiratory infections. This is a common consequence that is observed in babies who did not receive adequate nutrition during the prenatal period. Choices A, B, and D are incorrect. While malnourished babies may have feeding challenges, rejecting breast milk is not a common consequence. Enlarged hearts are not typically associated with prenatal malnutrition, and having a higher-than-average birth weight is unlikely in malnourished babies.
3. According to Jean Piaget, what is the balance between internal structures and information that children encounter in their everyday worlds?
- A. imitation
- B. adaptation
- C. cognition
- D. equilibrium
Correct answer: D
Rationale: According to Jean Piaget, equilibrium is the balance between what children already know (internal structures) and the new information they encounter. Imitation (choice A) is not directly related to this concept. Adaptation (choice B) involves adjusting to new information and is part of Piaget's theory, but it does not specifically refer to the balance between internal structures and external information. Cognition (choice C) is a broader term that encompasses mental processes, including thinking, learning, and problem-solving, but it is not specifically about the balance between internal structures and external information as equilibrium is.
4. Konrad Lorenz and Niko Tinbergen laid the modern foundations for __________.
- A. ethology
- B. social learning theory
- C. psychoanalytic theory
- D. cognitive-developmental theory
Correct answer: A
Rationale: Konrad Lorenz and Niko Tinbergen are considered the founders of ethology, a branch of biology and psychology that focuses on the study of animal behavior in natural environments. Their work laid the modern foundations for ethology, which examines the behavior of animals in relation to their natural habitats and evolutionary history. Choice B, social learning theory, is incorrect as it pertains to a different area of psychology that focuses on how people learn through observing others. Choice C, psychoanalytic theory, is also incorrect as it is a psychological theory developed by Sigmund Freud that emphasizes the role of unconscious conflicts in determining behavior. Choice D, cognitive-developmental theory, is incorrect as it refers to the work of Jean Piaget in understanding the development of human cognition in children.
5. Under ethical standards, when is deception permitted in research studies?
- A. if the participants are young enough that they would not understand the deception
- B. if investigators satisfy institutional review boards that such practices are necessary
- C. if researchers can observe participants from behind one-way mirrors
- D. if the participants give informed consent and the researchers never reveal the real purpose of the study
Correct answer: B
Rationale: Ethical standards permit deception in research studies if investigators satisfy institutional review boards that such practices are necessary. Institutional review boards are responsible for ensuring that research studies comply with ethical guidelines and protect the welfare of study participants. Deception should only be used when necessary, and the board's approval indicates that safeguards are in place to minimize harm to participants. Choices A, C, and D are incorrect because ethical deception in research studies is not based on the age of participants, observing from behind mirrors, or obtaining informed consent without revealing the study's real purpose.
