DEVELOPMENT
• Development refers to the physiological, behavioral, cognitive, and social

year.

DEATH, DYING, AND BEREAVEMENT
Elizabeth Kübler-Ross describes five phases of grief through which people
pass in grappling with the knowledge that they or someone close to them is
dying:
1. Denial: “I feel fine.” “This can’t be happening; not to me.”
2. Anger: “Why me? It’s not fair!” “How can this happen to me?” “Who is to
blame?”
3. Bargaining: “Just let me live to see my children graduate.” “I’d do anything
for a few more years.” “I’d give my life savings if…”
4. Depression: “I’m so sad, why bother with anything?” “I’m going to die.
What’s the point?” “I miss my loved ones—why go on?”
5. Acceptance: “I know my time has come; it’s almost my time.”v

WHAT IS LIFESPAN DEVELOPMENT AND
DEVELOPMENTAL TASK?
• Lifespan development - The term lifespan development refers to age-
related changes that occur from birth, throughout a persons' life, into

• Developmental Task - A developmental task is a task that arises at or
about a certain period in life, unsuccessful achievement of which leads
to inability to perform tasks associated with the next period or stage
