Human Growth and Development Exam 1

1. 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).

2. __________ doubles the risk of SIDS.

A. Failure to tightly swaddle an infant during sleep
B. Use of a pacifier or a security blanket
C. Placing an infant to sleep on his back
D. Cigarette smoking by a caregiver Answer: D Page Ref: 106 Box: BIOLOGY AND ENVIRONMENT: The Mysterious Tragedy of Sudden Infant Death Syndrome Skill Level: Understand Topic: The Newborn BabyÃ¢â‚¬â„¢s Capacities Difficulty Level: Moderate

Correct answer: D

Rationale: Cigarette smoking by a caregiver doubles the risk of SIDS. Secondhand smoke exposure can increase the likelihood of SIDS due to the toxins and chemicals present in cigarette smoke. It is important to have a smoke-free environment for infants to reduce the risk of SIDS.

3. Dr. Torrez believes that how conflicts between biological drives and social expectations are resolved determines the person's ability to learn, to get along with others, and to cope with anxiety. Dr. Torrez accepts the __________.

A. psychoanalytic perspective
B. psychosocial theory
C. cognitive-developmental theory
D. social learning theory

Correct answer: A

Rationale: Dr. Torrez's belief about conflicts between biological drives and social expectations influencing a person's ability to learn, get along with others, and cope with anxiety aligns with the psychoanalytic perspective. This perspective, developed by Sigmund Freud, focuses on the unconscious mind, early childhood experiences, and the resolution of inner conflicts as important factors in shaping personality and behavior. The other choices are incorrect because psychosocial theory, cognitive-developmental theory, and social learning theory do not specifically focus on conflicts between biological drives and social expectations as central to understanding human behavior and development.

4. Which statement about a blastocyst is true?

A. It consists of a single cell.
B. It is a structure that feeds the developing organism.
C. Between the seventh and ninth days, it burrows deep into the uterine lining.
D. It is a membrane that helps to keep the temperature of the prenatal world constant.

Correct answer: C

Rationale: The statement that is true about a blastocyst is that between the seventh and ninth days, it burrows deep into the uterine lining. This process, known as implantation, is essential for the blastocyst to establish a connection with the mother's body and receive nutrients for further development. It is a critical stage in prenatal development and sets the foundation for pregnancy. Choices A, B, and D are incorrect. A blastocyst is not a single cell but rather a structure composed of many cells. It is not a structure that feeds the developing organism; instead, it implants in the uterine lining to receive nutrients. It is not a membrane that regulates temperature but plays a crucial role in the initial stages of pregnancy by implanting in the uterus.

5. __________ supplementation early in pregnancy reduces the risk of abnormalities of the neural tube, the circulatory system, and the urinary tract.

A. Vitamin A
B. Folic acid
C. Vitamin D
D. Vitamin C

Correct answer: B

Rationale: Folic acid supplementation early in pregnancy is crucial as it reduces the risk of abnormalities in the developing fetus. It is specifically known to prevent issues related to the neural tube, circulatory system, and urinary tract. Vitamin A, Vitamin D, and Vitamin C do not play the same role as folic acid in preventing these specific birth defects, making them incorrect choices.
