Unlike Jean Piaget, Lev Vygotsky viewed cognitive development as a _________ process.
- A. socially mediated
- B. genetically predictable
- C. preoperational
- D. neurological
Correct Answer: A
Rationale: Lev Vygotsky viewed cognitive development as a socially mediated process, emphasizing the role of social interactions and cultural influences in shaping a child's cognitive development. This is in contrast to Jean Piaget, who focused more on individual interactions with the environment. Vygotsky believed that cognitive development is significantly influenced by social interactions with others, highlighting the importance of collaborative learning and cultural context. Choices B, C, and D are incorrect as they do not align with Vygotsky's perspective on cognitive development.

The lifespan perspective on human development assumes that development is __________.
- A. static and stable
- B. multidimensional and multidirectional
- C. continuous, rather than discontinuous
- D. largely the result of heredity
Correct Answer: B
Rationale: The lifespan perspective on human development assumes that development is multidimensional and multidirectional. This means that development occurs in various domains (such as physical, cognitive, and psychosocial) and can involve gains and losses as individuals age. This perspective recognizes that human development is complex and dynamic, involving various factors and pathways over the course of a person's life. Choices A, C, and D are incorrect because human development is not static and stable (A), can involve both continuous and discontinuous changes (C), and is influenced by a combination of heredity and environment rather than solely by heredity (D).
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.
Which statement about the Nurse-Family Partnership is true?
- A. It is an international program to reduce the risk of teratogens.
- B. One of its goals is to promote competent early caregiving.
- C. It is a series of childbirth classes offered at many U.S. hospitals.
- D. It provides family planning and genetic counseling to couples.
Correct Answer: B
Rationale: The statement that is true about the Nurse-Family Partnership is that one of its goals is to promote competent early caregiving. The program provides support and guidance to first-time mothers to help them develop their caregiving skills and promote healthy child development. Choice A is incorrect because the program focuses on promoting healthy child development and supporting mothers, not specifically reducing the risk of teratogens. Choice C is incorrect because the Nurse-Family Partnership is not a series of childbirth classes but a program that involves home visits and support. Choice D is incorrect because the program's main focus is on supporting mothers in caregiving and child development, not primarily on family planning and genetic counseling.
Dr. George predicted that positive reinforcement would increase prosocial behavior in preschoolers. Dr. George's prediction is an example of a __________.
- A. theory
- B. research question
- C. hypothesis
- D. research design
Correct Answer: C
Rationale: Dr. George's prediction that positive reinforcement would increase prosocial behavior in preschoolers is an example of a hypothesis. A hypothesis is a specific, testable prediction about the relationship between variables based on existing knowledge or theories. In this case, Dr. George is making a prediction about the effect of positive reinforcement on prosocial behavior, which can be tested through research. Choice A, 'theory,' is incorrect because a theory is a broader explanation that integrates a range of findings and observations. Choice B, 'research question,' is incorrect as it refers to an inquiry that asks about the relationship between variables but lacks the specificity and testability of a hypothesis. Choice D, 'research design,' is incorrect as it pertains to the overall strategy or plan for conducting a research study, not the specific prediction Dr. George made.
Anoxia during labor and delivery can cause __________.
- A. spina bifida
- B. anencephaly
- C. cerebral palsy
- D. muscular dystrophy
Correct Answer: C
Rationale: Anoxia during labor and delivery can cause cerebral palsy. Cerebral palsy is a group of disorders that affect a person's ability to move and maintain balance and posture. It is caused by damage to the developing brain, often due to a lack of oxygen during labor and delivery. Spina bifida (Choice A) is a neural tube defect that occurs during embryonic development and is not directly caused by anoxia during labor. Anencephaly (Choice B) is a severe neural tube defect where the baby is born without parts of the brain and skull, not typically caused by anoxia during labor. Muscular dystrophy (Choice D) is a genetic disorder characterized by progressive muscle weakness and is not directly related to anoxia during labor and delivery.
