Human Growth and Development Exam 1
1. During pregnancy, the placenta __________.
- A. forms in the second trimester of pregnancy
- B. encloses the developing organism in amniotic fluid
- C. contains one large vein that delivers nutrients to the embryo
- D. delivers food and oxygen to the developing organism
Correct answer: D
Rationale: The placenta delivers food and oxygen to the developing organism during pregnancy. It is a temporary organ that forms in the first trimester of pregnancy. Choice A is incorrect as the placenta forms in the first trimester, not the second trimester. Choice B is incorrect as the amniotic sac, not the placenta, encloses the developing organism in amniotic fluid. Choice C is incorrect as the placenta contains blood vessels (arteries and veins) that deliver nutrients to the embryo, not just one large vein.
2. Piaget’s cognitive-developmental theory, information processing, and Vygotsky’s sociocultural theory all stress __________.
- A. nature over nurture
- B. changes in thinking
- C. unconscious motives and drives
- D. the effects of punishment and reinforcement on behavior Answer: B Page Ref: 26 Skill Level: Understand development. Topic: Comparing and Evaluating Theories Difficulty Level: Difficult
Correct answer: B
Rationale: Piaget’s cognitive-developmental theory, information processing, and Vygotsky’s sociocultural theory all stress changes in thinking. These theories focus on how cognitive abilities develop over time, emphasizing the growth and transformation of thinking processes rather than static traits or characteristics.
3. What did Ivan Pavlov discover?
- A. observational learning
- B. classical conditioning
- C. the ego's positive contributions to development
- D. the clinical method
Correct answer: B
Rationale: Ivan Pavlov discovered classical conditioning. This is a form of learning in which a neutral stimulus becomes associated with a meaningful stimulus and acquires the capacity to elicit a similar response. Pavlov's famous experiment with dogs, where he conditioned them to salivate at the sound of a bell, demonstrated this principle. Choices A, C, and D are incorrect because Pavlov's work primarily focused on classical conditioning, not observational learning, ego contributions to development, or the clinical method.
4. As school-age children move into adolescence, self-concept is increasingly vested in feedback from __________.
- A. close friends
- B. family members
- C. younger children
- D. the inner self
Correct answer: A
Rationale: During adolescence, individuals start to rely more on feedback from close friends to develop their self-concept. Close friends play a significant role during this transitional period as they provide peer validation, support, and influence. Family members, although important, may not hold the same level of influence on self-concept during adolescence as close friends do. Younger children are unlikely to provide the necessary feedback and validation needed during this developmental stage. While self-reflection and understanding the inner self are vital for personal growth, during adolescence, external feedback from close friends tends to have a more pronounced impact on shaping self-concept.
5. Swaddling newborns __________.
- A. increases crying
- B. hinders early motor development
- C. promotes an insecure attachment relationship
- D. restricts movement and increases warmth
Correct answer: D
Rationale: Swaddling newborns restricts their movement by wrapping them snugly in a blanket, which helps to mimic the feeling of security they had in the womb. It also helps to maintain their warmth and can promote better sleep patterns. Choices A, B, and C are incorrect because swaddling does not increase crying, hinder early motor development, or promote an insecure attachment relationship. Instead, it provides comfort, warmth, and a sense of security for newborns.
