Quiz: Lifespan Development Psychology — 11 questions

1. Which sequence best represents the main progression of prenatal development from conception to attachment in the uterus?

A. Cell division, implantation, fertilization, zygote formation, and blastocyst formation

B. Zygote formation, implantation, fertilization, cell division, and blastocyst formation

C. Implantation, fertilization, blastocyst formation, zygote formation, and cell division

D. Fertilization, zygote formation, cell division, blastocyst formation, and implantation

Answer: (D)

Explanation

Prenatal development follows the progression from fertilization and zygote formation through cellular division and blastocyst formation to implantation. Implantation occurs after the blastocyst has formed, so sequences placing it earlier are incorrect.

2. What is the initial stage of prenatal development called, during which the fertilized egg attaches to the uterine wall?

A. Embryonic stage

B. Fetal stage

C. Neonatal stage

D. Germinal stage

Answer: (D)

Explanation

The germinal stage is the first phase of prenatal development, lasting from day 0 to day 14, and ends with implantation of the blastocyst into the uterine wall. The embryonic stage follows, involving development of the embryo.

3. What happens during fertilization in human prenatal development?

A. An egg and sperm fuse, combining 23 chromosomes from each gamete into 46 chromosomes

B. The resulting zygote divides repeatedly, producing many cells with 46 chromosomes

C. The outer cell mass forms the placenta while the inner cell mass forms the embryo

D. The blastocyst attaches to the uterine wall after developing from an inner cell mass

Answer: (A)

Explanation

Fertilization is the fusion of a human egg and sperm, bringing together 23 female chromosomes and 23 male chromosomes to produce 46. Repeatedly producing more cells describes cellular division rather than the fusion of gametes.

4. During which period does the embryo develop the placenta and the inner cell mass that becomes the embryo?

A. During the germinal stage

B. During the fetal stage

C. During the neonatal period

D. During the embryonic stage

Answer: (D)

Explanation

The embryonic stage is when the outer cell mass develops into the placenta and the inner cell mass into the embryo. The germinal stage involves fertilization and implantation, while the fetal stage is mainly growth and development.

5. Which statement correctly distinguishes nature from nurture in prenatal development?

A. Nature concerns maternal behavior, whereas nurture concerns chromosome number

B. Nature concerns implantation, whereas nurture concerns the formation of gametes

C. Nature involves genetic influences, whereas nurture involves environmental influences

D. Nature involves environmental influences, whereas nurture involves genetic influences

Answer: (C)

Explanation

Nature refers to genetic influences, while nurture refers to environmental influences affecting development. Reversing these definitions confuses the biological and environmental sources of influence.

6. What is the primary purpose of motor development in infancy?

A. To learn language and social skills

B. To establish emotional bonds with caregivers

C. To develop muscular coordination necessary for physical activities

D. To acquire cognitive abilities like problem-solving

Answer: (C)

Explanation

The main purpose of motor development in infancy is to develop muscular coordination required for physical activities such as grasping, sitting, and walking. While language, emotional bonds, and cognition are important, they are separate developmental domains.

7. How does epigenetics connect nature and nurture during prenatal development?

A. It identifies environmental substances that physically replace inherited chromosomes

B. It explains how environmental conditions can affect the activity or expression of genes

C. It describes how chromosome numbers increase when embryonic cells divide

D. It refers to the fusion of genetic material from an egg and a sperm cell

Answer: (B)

Explanation

Epigenetics describes how environmental conditions can affect genes, providing a link between inherited biology and environmental experience. Cell division, chromosome replacement, and gamete fusion are different biological processes.

8. During which time frame does the fetal stage of prenatal development occur, characterized by final growth and the development of human features?

A. From conception to week 8

B. Week 1 to week 8

C. Day 0 to day 14

D. Week 9 to week 38

Answer: (D)

Explanation

The fetal stage lasts from week 9 to week 38 and involves final growth, development of human features, and preparation for birth. The other options refer to earlier stages such as germinal and embryonic phases.

9. How do secure and avoidant attachment patterns differ in infants' responses to separation and reunion with their caregivers?

A. Securely attached infants become distressed during separation and seek comfort upon reunion, while avoidant infants usually do not show distress and avoid contact after separation.

B. Securely attached infants show no reaction to separation and reunion, while avoidant infants become highly distressed and resist contact.

C. Securely attached infants are indifferent to strangers, while avoidant infants are wary of strangers and prefer their caregivers.

D. Securely attached infants ignore their caregivers during separation and avoid contact on reunion, whereas avoidant infants become extremely distressed and seek comfort.

Answer: (A)

Explanation

Secure attachment is characterized by infants being distressed during separation and seeking comfort upon reunion, whereas avoidant infants typically do not show distress and tend to avoid contact. This difference reflects their distinct emotional bonds with caregivers.

10. Who proposed the concept of attachment as a close emotional bond of affection between infants and caregivers?

A. John Bowlby

B. Mary Ainsworth

C. Harry Harlow

D. Erik Erikson

Answer: (A)

Explanation

John Bowlby is credited with proposing that infants are biologically programmed to elicit protective responses from adults, forming the basis of attachment theory. Harry Harlow challenged reinforcement theory with his rhesus monkey experiments, Mary Ainsworth developed attachment patterns, and Erik Erikson focused on psychosocial stages.

11. What is the primary cause of the rapid development of language skills in early childhood?

A. The child's innate ability to learn language through biological programming.

B. The genetic predisposition to develop language skills without environmental influence.

C. The social interactions and communication experiences with caregivers and peers.

D. The formal education and structured language lessons received in preschool.

Answer: (C)

Explanation

Early language development is primarily driven by social interactions and communication experiences with caregivers and peers, which facilitate learning through exposure and practice. While biological factors play a role, environmental socialization is crucial for language acquisition.
