Key Takeaways Explain This Topic AI

Prenatal development is influenced by teratogens, maternal health, and environmental factors that can have lasting effects

Typical developmental milestones provide benchmarks but must be considered within cultural context

Aging and gerontology are increasingly important as the population ages, requiring knowledge of both normal aging and age-related conditions

Kübler-Ross identified five stages of grief (denial, anger, bargaining, depression, acceptance) that are not necessarily linear

The dual-process model of grief describes oscillation between loss-oriented and restoration-oriented coping

Major life transitions (marriage, divorce, retirement, disability) can trigger both crisis and growth

Social workers must distinguish between typical developmental challenges and clinical disorders requiring intervention

Last updated: October 2026

Social workers must understand human development across the entire lifespan — from prenatal development through end of life — to effectively assess clients, identify developmental challenges, and provide appropriate interventions. The ASWB exam tests your ability to recognize both typical (normative) and atypical (non-normative) development and apply this knowledge to clinical practice.

Prenatal Development

Prenatal development occurs in three stages:

Germinal Period (Weeks 1-2): The fertilized egg (zygote) divides and implants in the uterine wall

Embryonic Period (Weeks 3-8): Major organs and body structures form; the organism is most vulnerable to teratogens (substances that cause birth defects)

Fetal Period (Weeks 9-Birth): Continued growth and maturation of all body systems

Teratogens that can harm prenatal development include:

Alcohol: Leading preventable cause of intellectual disability; can cause Fetal Alcohol Spectrum Disorders (FASD)

Tobacco: Associated with low birth weight, premature birth, and SIDS

Illicit drugs: Opioids, cocaine, methamphetamine can cause neonatal abstinence syndrome and developmental delays

Certain medications: Some prescription drugs (e.g., certain anti-epileptic drugs, isotretinoin) are teratogenic

Environmental toxins: Lead, mercury, pesticides
Key Developmental Milestones

Age Physical Cognitive Social-Emotional
0-12 months Sits, crawls, may walk Object permanence developing Attachment forming, stranger anxiety

1-3 years Walking, running, fine motor skills Language explosion, symbolic play Autonomy, parallel play, tantrums

3-6 years Improved coordination Preoperational thinking, imagination Initiative, cooperative play, friendships

6-12 years Growth slows, puberty begins Concrete operations, reading/math Industry, peer relationships, moral development

12-18 years Puberty, physical maturation Abstract reasoning, identity formation Identity exploration, peer influence, risk-taking

18-40 years Peak physical condition, then gradual decline Postformal thinking, career development Intimacy, partnerships, parenting

40-65 years Menopause/andropause, sensory changes Expertise and crystallized intelligence peak Generativity, career reflection, caring for aging parents

65+ years Physical decline, chronic conditions Wisdom, some cognitive decline Life review, integrity vs. despair, loss

Aging and Gerontology

As the population ages, social workers increasingly serve older adults. Key concepts in gerontological social work include:

Normal aging vs. pathological aging: Not all cognitive decline is dementia; some memory changes are normal with aging

Ageism: Prejudice and discrimination against older adults that affects access to services and quality of care

Dementia types: Alzheimer's disease (most common), vascular dementia, Lewy body dementia, frontotemporal dementia

Elder abuse: Physical, emotional, sexual, financial abuse, and neglect — nearly every state (New York is the exception) names mandated reporters of elder abuse, and who must report varies by state

Advance directives: Living wills, healthcare proxies, and do-not-resuscitate (DNR) orders

Caregiver stress: Family members caring for aging relatives often experience burnout, depression, and social isolation
