Discussion: Classifications of Life-Span Development

 
When did you become an adult? Was it the day you graduated from high school? Or, was it the day you moved out of your parents’ or caregivers’ home? Your description of what it means to be an adult and how and when an adolescent transitions into adulthood may differ from that of your colleagues.
The authors of your course text, Zastrow, Kirst-Ashman, & Hessenauer, use the term young and middle adulthood to identify the life-span time period between age 18 and 65. This classification distinguishes this time in the life of an individual from childhood and adolescence and from the later years of adulthood.
Is the authors’ young and middle adulthood classification a useful one? What is especially useful and not useful about the classification? What changes would you make to the authors’ classification to make it more applicable to your role as a social worker?
For this Discussion, you analyze the author’s life-span classification and suggest ways to improve it.
By Day 3  support your posts with specific references to the resources. If you are using additional articles, be sure to provide full APA-formatted citations for your references below:

Post:

A new classification (or possibly multiple classifications) to replace the authors’ young and middle adulthood classification
A definition of your new classification(s)
Support for your new classification(s). for example, this support may include references to theory and empirical research findings and should reflect the current understanding of biological, psychological, and social development
An implication your new classification might have regarding social work practice

By Day 5 Help with one paragraph Responding to at least two colleagues for the following question below:

Read a selection of your colleagues’ posts.
Respond to at least two colleagues whose classifications differ from your own by critiquing their classifications. In addition, suggest one way you might apply each colleague’s life-span classification to your social work practice.
