International representation in the psychological literature

The author searched PsycLit records to examine the representation of psychological research from outside the US and changes in international representation over time. American research dominates, but international representation has increased since 1975. Western Europe, Japan, Australia, and Israel in particular have become better represented. In contrast, developing nations have remained poorly represented for most of the time period examined. Relative national influence may accurately reflect the numbers of psychologists in general, and research psychologists in particular, in each nation. Psychologists in developing nations also focus on teaching, clinical, and social issues, and have few resources for research activities. International representation is likely to continue increasing.
