American Psychological Society (APS)
The American Psychological Society represents the interests of academic, applied, and science-oriented psychology and psychologists. The formation of APS originated from the Assembly for Scientific and Applied Psychology (ASAP), a group that attempted to reform the American Psychological Association (APA) to give the scientists greater representation and autonomy. APS prides itself on its strong, committed leadership and minimal bureaucracy. It publishes two bimonthly journals, Psychological Science and Current Directions in Psychological Science, and produces a monthly newsletter. The APS holds annual conventions. The goal is to apply the knowledge gained from scientific psychology to address such social ills as illiteracy, substance abuse, violence, as well as mental and physical health.
