TY - JOUR A1 - Kliegl, Reinhold A1 - Bates, Douglas T1 - International collaboration in psychology is on the rise T2 - Scientometrics : an international journal for all quantitative aspects of the science of science, communication in science and science policy N2 - There has been a substantial increase in the percentage for publications with co-authors located in departments from different countries in 12 major journals of psychology. The results are evidence for a remarkable internationalization of psychological research, starting in the mid 1970s and increasing in rate at the beginning of the 1990s. This growth occurs against a constant number of articles with authors from the same country; it is not due to a concomitant increase in the number of co-authors per article. Thus, international collaboration in psychology is obviously on the rise.
