Human Growth and Development Exam 1
1. 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.
2. Which of the following best describes a sequential design?
- A. Does not address diversity in developmental outcomes.
- B. Permits researchers to check if cohort effects are operating.
- C. Is less efficient than a longitudinal design.
- D. Makes cross-sectional, but not longitudinal, comparisons.
Correct answer: B
Rationale: A sequential design permits researchers to check if cohort effects are operating. This design involves combining cross-sectional and longitudinal research, allowing for the comparison of different cohorts at different ages. By using this approach, researchers can determine if developmental changes observed are due to age or generation-specific factors. Therefore, a sequential design is valuable in addressing the potential influence of cohort effects on developmental outcomes. Choices A, C, and D are incorrect because a sequential design does not neglect diversity in developmental outcomes, is not necessarily less efficient than a longitudinal design, and can make both cross-sectional and longitudinal comparisons.
3. In females, the twenty-third pair of chromosomes is labeled as __________.
- A. an autosome
- B. dizygotic
- C. XX
- D. XY
Correct answer: C
Rationale: In females, the twenty-third pair of chromosomes is indeed labeled as XX. This pair of chromosomes determines the biological sex of females. Choice A, 'an autosome,' is incorrect as autosomes refer to the non-sex chromosomes. Choice B, 'dizygotic,' is incorrect as it relates to twins. Choice D, 'XY,' is incorrect as it represents the chromosome pair found in males.
4. Striving for continuity is essential for attaining Erikson's sense of __________, which depends on preserving a sense of personal history.
- A. intimacy
- B. ego identity
- C. ego integrity
- D. initiative
Correct answer: C
Rationale: The correct answer is C: 'ego integrity.' Erikson's concept of ego integrity involves reflecting on life with a sense of satisfaction, which requires continuity in personal history. This sense of integrity is developed in late adulthood and is characterized by a feeling of wholeness and fulfillment. Choices A, B, and D are incorrect. Intimacy (choice A) relates to forming close relationships, ego identity (choice B) pertains to a stable sense of self, and initiative (choice D) is about being proactive and exploring the environment, which are not directly associated with preserving personal history for a sense of satisfaction in later life.
5. 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.
