Human Growth and Development Final Exam Quizlet

1. Brain growth is especially dramatic during __________, when the brain more than doubles in size.

A. the first year
B. the second year
C. middle childhood
D. adolescence

Correct answer: A

Rationale: Brain growth is especially dramatic during the first year of life when the brain more than doubles in size. This period is characterized by rapid neural development and growth. The brain doesn't double in size during the second year, making choice B incorrect. Middle childhood and adolescence do not represent periods where the brain more than doubles in size, making choices C and D incorrect, respectively.

2. In an investigation of over 120,000 New York City births, babies born even 1 to 2 weeks early __________ than children who experienced a full-length prenatal period.

A. showed lower reading and math scores at a third-grade follow-up
B. were less likely to suffer from childhood obesity
C. were less likely to suffer from neurological impairments
D. showed higher language and social/emotional scores in early childhood

Correct answer: A

Rationale: In the investigation of over 120,000 New York City births, babies born even 1 to 2 weeks early showed lower reading and math scores at a third-grade follow-up compared to children who experienced a full-length prenatal period. This suggests that being born slightly premature can have an impact on cognitive development, leading to educational challenges later on. Choices B, C, and D are incorrect because the study specifically highlighted lower reading and math scores, not a reduced likelihood of suffering from childhood obesity or neurological impairments, or improved language and social/emotional scores in early childhood.

3. By the twelfth week of pregnancy, __________.

A. the sex of the fetus can be detected with ultrasound
B. the mother can feel the movements of the fetus
C. the fetus is viable and can survive if born early
D. synchrony between fetal heart rate and motor activity peaks Answer: A Page Ref: 79 Skill Level: Understand Copyright Ã‚Â© 2018 Laura E. Berk. All Rights Reserved. 6 Test Bank for Berk, Development Through the Lifespan, 7e Topic: Prenatal Development Difficulty Level: Moderate

Correct answer: A

Rationale: By the twelfth week of pregnancy, the sex of the fetus can be detected with ultrasound. Ultrasound technology allows for visualization of the developing fetus and identification of physical characteristics, such as sex, during prenatal appointments.

4. Which statement about epidural analgesia is true?

A. It numbs the entire lower half of the body.
B. It limits pain reduction to the pelvic region.
C. It strengthens uterine contractions.
D. It shortens the length of labor.

Correct answer: B

Rationale: The correct statement about epidural analgesia is that it limits pain reduction to the pelvic region by blocking nerve signals from that specific area, providing pain relief during labor and delivery. Choice A is incorrect because epidural analgesia does not numb the entire lower half of the body. Choice C is incorrect because epidural analgesia does not strengthen uterine contractions; in fact, it may sometimes weaken them. Choice D is incorrect because epidural analgesia does not shorten the length of labor; it can sometimes prolong labor.

5. G. Stanley Hall and his student, Arnold Gesell, __________.

A. discovered that prenatal growth is strikingly similar in many species
B. launched the normative approach
C. constructed the first standardized intelligence test
D. were the forefathers of psychoanalytic theory

Correct answer: B

Rationale: G. Stanley Hall and his student, Arnold Gesell, launched the normative approach. This approach involves studying large numbers of people of different ages and examining the age-related averages of behaviors to establish norms or typical development patterns. These scholars focused on the systematic observation of how and when certain behaviors appear in children. Choices A, C, and D are incorrect because they do not accurately reflect the contributions of G. Stanley Hall and Arnold Gesell in the field of developmental psychology.
