Development of relational wisdom and happiness in late adulthood
The field of adult development and aging has focused primarily on the issue of the well-being of the older adult (Lamb & Freund, 2010; Overton, 2010).1 Two central issues related to wellbeing are wisdom and happiness. It is generally assumed that wisdom and happiness increase with age, but this assumption still warrants further examination. For example, while several studies in the U.S. support this relationship (e.g., Ardelt, 1997, 2004), data in Japan, the "grayest" country in the world, reveal a different pattern. These studies suggest that happiness declines with age (Frey & Stutzer, 2001).
