Human Growth and Development Final Exam Answers
1. When Baby Ian is held horizontally on his back, he sometimes makes an “embracing” motion by arching his back, extending his legs, throwing his arms outward, and then bringing his arms in toward his body. Ian is demonstrating the __________.
- A. palmar grasp
- B. Moro reflex
- C. tonic neck reflex
- D. Babinski reflex
Correct answer: B
Rationale: Baby Ian is demonstrating the Moro reflex. The Moro reflex is a normal newborn reflex that occurs when a baby feels like they are falling or losing support. It is characterized by arching the back, extending the legs, throwing the arms outward, and then bringing the arms in toward the body. This reflex is a primitive survival instinct that typically disappears around 6 months of age. Choice A, palmar grasp, involves the baby's fingers closing around an object when it touches their palm. Choice C, tonic neck reflex, involves the baby assuming a fencing position when their head is turned to one side. Choice D, Babinski reflex, is characterized by the fanning out and curling of the baby's toes when the sole of the foot is stroked.
2. Self-esteem takes on a hierarchical structure in __________.
- A. toddlerhood
- B. preschool
- C. middle childhood
- D. adolescence
Correct answer: C
Rationale: In middle childhood, self-esteem becomes more differentiated and organized into a hierarchy based on various domains of competence. This period marks a time when children start to compare their abilities in different areas, such as academic performance, social skills, and physical abilities. Toddlerhood and preschool years are characterized by the development of basic self-awareness and self-concept, but self-esteem hierarchy typically emerges later in middle childhood and further solidifies in adolescence as individuals navigate complex social dynamics and personal identities.
3. Which expectant mother has the greatest risk of a baby born with fetal alcohol syndrome?
- A. Chloe, a Caucasian American
- B. Latima, an African American
- C. Yvonne, a Native American
- D. Ming, an Asian American Answer: C Page Ref: 85 Skill Level: Apply known or suspected teratogens. Topic: Prenatal Environmental Influences Difficulty Level: Moderate
Correct answer: C
Rationale: According to research, Native American populations have the highest prevalence of fetal alcohol syndrome (FAS) in the United States. This increased risk is due to various social, cultural, and environmental factors within Native American communities.
4. What is a major strength of the longitudinal design?
- A. Examine relationships between early and later behaviors
- B. Collect a large amount of data in a short time span
- C. Explore similarities among children of different cohorts
- D. Study participants differing in age at the same point in time
Correct answer: A
Rationale: A major strength of the longitudinal design is that researchers can examine relationships between early and later behaviors. This design allows researchers to observe and track changes in the same participants over an extended period of time, providing valuable insights into developmental trajectories and how behaviors are connected across different stages of life. Choice B is incorrect because longitudinal studies track changes over time, not necessarily collect a large amount of data in a short time span. Choice C is incorrect as it refers to cross-sectional studies rather than longitudinal studies. Choice D is incorrect as it describes a cross-sectional design where participants of different ages are studied at the same time.
5. Dr. Langley's work is devoted to understanding constancy and change throughout the lifespan. Dr. Langley's field of study is __________.
- A. genetics
- B. clinical psychology
- C. adolescent development
- D. developmental science
Correct answer: D
Rationale: Dr. Langley's work being focused on understanding constancy and change throughout the lifespan aligns with the field of developmental science, which studies how individuals grow and change from birth through old age. This field encompasses the study of physical, cognitive, social, emotional, and other aspects of development across the lifespan. Choice A, genetics, primarily focuses on the study of genes, heredity, and genetic variation, which is not directly related to understanding constancy and change throughout the lifespan. Choice B, clinical psychology, concentrates on the diagnosis and treatment of mental, emotional, and behavioral disorders rather than the broader study of development across the lifespan. Choice C, adolescent development, is more specific and limited in scope compared to the comprehensive study of development across the entire lifespan, which is the focus of developmental science.
