The present study compared active versus passive dimension in explaining how emotions shift as people age, researcher Catherine Ross said. "The passive/positive combination reveals that contentment, calm and ease are some of the most common emotions people feel as they age," Ms Ross said, adding that emotions that were both active and negative, such as anxiety and anger, were unlikely among the elderly. During the study, the researchers grouped the emotions in four categories: active, passive, positive and negative. Findings revealed that women had more negative than positive emotions, and more passive than active emotions than men. Also, participants with higher income and education levels had significantly more positive emotions than those with lower income and education levels.
