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. In a historic experiment with 11-month-old Albert, John Watson demonstrated that __________.
- A. children cannot be conditioned to fear a formerly neutral stimulus
- B. infants as young as a few months old will repeat a behavior to obtain a desirable reward
- C. children can be conditioned to fear a formerly neutral stimulus
- D. children have an innate, inborn fear of rats Answer: C Page Ref: 16 Skill Level: Understand Topic: Mid-Twentieth-Century Theories Difficulty Level: Moderate
Correct answer: C
Rationale: In the historic experiment with 11-month-old Albert conducted by John Watson, it was demonstrated that children can be conditioned to fear a formerly neutral stimulus. This is known as classical conditioning, where a neutral stimulus is repeatedly paired with an unconditioned stimulus to create a conditioned response. In this case, Albert was conditioned to fear a white rat by pairing the rat with a loud noise. This experiment showcased the power of conditioning in shaping behavior and emotional responses in children.
3. Who is generally regarded as the founder of the child study movement?
- A. Charles Darwin
- B. G. Stanley Hall
- C. Alfred Binet
- D. Sigmund Freud
Correct answer: B
Rationale: G. Stanley Hall is generally regarded as the founder of the child study movement. He established the first American research laboratory dedicated to child psychology and education, helping to pioneer the scientific study of child development. Choices A, C, and D are incorrect as they were not primarily associated with founding the child study movement. Charles Darwin is known for his contributions to the theory of evolution, Alfred Binet is famous for developing the first intelligence test, and Sigmund Freud is renowned for his work in psychoanalysis.
4. Dr. Kostel believes that development takes place in stages. This belief is consistent with the __________ perspective.
- A. nurture
- B. continuous
- C. discontinuous
- D. nature
Correct answer: C
Rationale: Dr. Kostel's belief in stage-based development aligns with the discontinuous perspective, which sees development as a series of distinct stages. The continuous perspective (choice B) suggests development as a smooth and gradual process without distinct stages. The nature perspective (choice D) focuses on genetic and hereditary influences on development. The nurture perspective (choice A) emphasizes the impact of environment and upbringing on development, which is not directly related to the belief in stage-based development.
5. During prenatal development, the ectoderm folds over to form the __________, or primitive spinal cord.
- A. mesoderm; neuron tract
- B. neural tube
- C. endoderm; neural tube
- D. neuron tract
Correct answer: B
Rationale: The correct answer is B. During prenatal development, the ectoderm folds over to form the neural tube, which eventually develops into the brain and spinal cord. The neural tube is the precursor to the central nervous system, including the primitive spinal cord. Choices A, C, and D are incorrect because the mesoderm does not form the neural tube, the endoderm is not involved in the formation of the central nervous system, and neuron tract is not the structure that forms the primitive spinal cord.
