在20世纪90年代,西方的心理学家们聚焦于研究“悲伤”。而现在,一场强调人的优点而非弱点的“积极心理学”运动正在蓬勃展开。心理学家们正在努力弄清楚人们快乐的动因,这已成为现时心理学家研究和关注的焦点。美国心理学家塞利格曼在他的《真正的快乐》一书中,对“快乐”进行了深入的研究,其观点受到普遍的重视。 In the 1990s, Western psychologists focused on studying “sadness.” Now, a “positive psychology” campaign that emphasizes human strengths rather than weaknesses is booming. Psychologists are trying hard to figure out the motivation of people’s happiness, which has become the focus of current psychologists’ research and attention. In his book True Happiness, American psychologist Seligman conducted an in-depth study of “happiness,” and his view was given universal attention.
