Final answer:
The situation described illustrates the disengagement theory, which states that it's natural for older individuals to withdraw from social connections as they age. The statement about Moustakas having a positive view of loneliness is false as it conflicts with the theory's premise.
Step-by-step explanation:
The statement 'Unlike most theorists, Moustakas has a positive view of loneliness' is false. The situation described in the question most closely illustrates the disengagement theory, which is a concept in social studies particularly relevant to sociology and gerontology. This theory suggests that as people age, it is natural and acceptable for them to withdraw from social connections and societal roles. The older man in the scenario retires from his job, stops partaking in leisure activities like golfing, cancels his newspaper subscription (which can be viewed as a form of social engagement), becomes a widower, and loses touch with both his children and friends. These actions align with the disengagement theory's premise that reducing involvement in one's social life is a part of the normal aging process.
