Final answer:
Most previous research in psychology focused on alleviating depression. Seligman's positive psychology emphasizes the development of individual strengths to achieve happiness, with the idea of 'flow' supporting his views. A comprehensive summary of Seligman's theory is that happiness stems from cultivating one's innate positive traits rather than material wealth or addressing negative states alone.
Step-by-step explanation:
Understanding Seligman's Ideas About Happiness
The field of psychology, according to most historical research, focused predominantly on improving the lives of very depressed people rather than studying happiness or why happy people are happy. This approach often meant moving individuals from a more negative state to a less negative one, but not necessarily towards positive well-being or happiness. In contrast, positive psychology, put forward by Seligman, emphasizes enhancing individual strengths such as kindness, originality, humor, optimism, and generosity to cultivate happiness.
The concept of flow, which relates to being completely immersed in activities to the point where time seems to stop, is a detail that supports Seligman's ideas about happiness and fulfillment. On the other hand, a somewhat less relevant piece of evidence might be the information on how cloistered nuns' longevity correlates with happiness scores, as it does not directly illustrate the process of how people can increase their happiness, unlike other details provided.
Summarizing Seligman's perspective, happiness is attained not by focusing on obstacles to happiness such as stress or mental illness, but rather by recognizing and developing one's valued personal characteristics. Although quality of life and material wealth may influence happiness, they offer more temporal boosts rather than sustained well-being. By capitalizing on inherent strengths, individuals can create natural buffers against adversity and improve their overall happiness.
