a. Humans are said to have three needs. How do you meet each of these needs? Using the language of the theory, what could happen if these needs are not met? How have your needs changed or remained the same across each contextual system?

b. List as many of your "values" as possible. Identify how these values affect your life and choices with each ecosystem. How have your values affected your interactions with your environments? How have your values affected your adaptation? How have your values been shaped by your microsystem and macrosystem?

c. Think of a problem or situation in your life that involves more than just you. Identify your personal characteristics that could be risk or protective factors for the problem. Then, consider how elements in each of the systems levels could contribute to or inhibit the problem. How could you use different contextual systems to help you deal with this situation? How could the addition of the PPCT model strengthen your analysis?
