ll be viewed. This is an ongoing process
that occurs throughout the adult's life.
Some writers on this topic postulate that adolescence and adulthood
has developmental stages much like those described by Piaget and Kohlberg
for children. These authors focus on the developmental stages of
adulthood, recognizing that adulthood involves the continuation of new
challenges, and not one static end state (Lucas and Kuhner, 1999). Just as
children integrate prior developmental milestones into themselves as they
move on to a new developmental level, adults continue to grow and evolve,
integrating prior experiences and knowledge into themselves as they face
This can be called "lifespan developmental psychology (Baltes et.
al., 1999). This approach to evaluating life at all points of the lifespan
includes the prior evolution of the individual, and asserts that
development involves three developmental goals: "growth, maintenance, and
regulation of loss" (Baltes et. al., 1999). The authors point out that
these stages do not occur at equal significance levels at all ages, and
that maintenance and regulation of loss become more significant as an
individual ages (Baltes et. al., 1999). They define "growth" as
activities and behaviors that increase the person's ability to function and
adapt. By maintenance, they mean behaviors that either nurture and support
the person's ability to function, or that restore the ability to cope after
significant loss. Adaptation remains a challenge throughout life, and as a
person ages, may become an important function as the individual loses
resources such as finances or people important to them (Baltes et. al.,
1999). Presumably, the ability to adapt would also be important as an
individual faced the problem of declining health.
These issues are especially important to society now because the
