CHINA | NATURE INDEX PSYCHOLOGY TO THE FORE AS SOCIAL PRESSURES MOUNT AGENCY/GETTY ANADOLU China has around 400 psychology schools and institutes — a steep increase from the five it counted in the 1980s. The expansion of the discipline is remarkable considering research ceased during the Cultural Revolution. Psychology schools and institutes were boarded up and psychologists banished to the countryside. Han Buxin, the deputy general of the Chinese Psychological Society, says the field’s roots in China stretch back more than two millennia to references in ancient texts such as the Analects of Confucius and Laozi’s Dao De Jing. Chinese polymath Chen Daqi opened the country’s first psychological laboratory in 1917 with the support of the education luminary, Cai Yuanpei. Cai studied under the German experimental psychologist Wilhelm Wundt in Leipzig in the early 1900s. When Cai was appointed head of Peking University in 1917, he supported Daqi’s plan to open the laboratory. More than a decade later Cai, as head of China’s peak science academy, helped found Zhou and colleagues found that feeling lonely rely on professional psychologists to help cope China’s Institute of Psychology, where reduced a person’s perception of social sup- with tragedy, whether a personal crisis or a Han now works. port, but triggered feelings of nostalgia.
