description: In recent years, there have been numerous calls for a greater internationalization within the field of psychology. With the introduction of the Internet in the 1990s, resources have become more accessible and communication gaps have become smaller as journals and documents from all over the world can be accessed more easily. Although there is some emerging evidence suggesting greater internationalization in psychology, the full extent to which internationalization has actually happened remains less clear. The present study sampled American journal articles from the years 1950-2010, taken across various high-impact journals in seven content areas of psychology, including those published by American Psychological Association (APA), Association for Psychological Sciences (APS), Psychonomic Society (PS), and other publishers. The results indicated that U.S. psychology journals are showing an increasingly greater proportion of international authors publishing in these journals, particularly in the last 30 years. Additional results on collaboration indicated that, while U.S. and non-U.S. collaborations are still relatively low in comparison to other collaborations, there has been an increase in multi-author collaborations over time. Possible reasons for observed results, as well as the benefits of the current study are also discussed.

description: Psychology journal articles from 1950-2010 were sampled across twenty-five journals, including those published by American Psychological Association (APA), Association for Psychological Science (APS), Psychonomic Society (PS), and others. Sampled journals were prestigious high-impact psychology journals that were not primarily interdisciplinary. The requirements were that no journal had any stated restrictions or preference policy toward American authors and that all journals sampled were published in the United States. Between three and five journals were sampled from each of seven content areas in psychology, with specific journals being chosen in consultation with researchers in each area. The seven content areas sampled were: General, Cognitive Psychology, Developmental and Educational Psychology, Behavioral Neuroscience, Social Psychology, Industrial-Organizational Psychology, and Clinical/Counseling Psychology. Not all journals were published during the entire period 1950-2010; some started later and were sampled from their year of origin through 2010. Also, some journals split into multiple journals, while others changed their name. See notes in Table 1 for further explanation and complete list of journals. The first and fourth issues from each journal from the years ending in zero and five in any given decade (e.g., 1990 and 1995 for the 1990s) and all articles in each issue sampled were included, excluding book reviews and comments, for a total of four issues per decade. The next available issue in the target year and/or the next year was used if the target issue or year was not available. The academic institution or other affiliation and the country of location of that institution was coded for each author; in cases of multiple authors, affiliation origin was noted for each co-author with equal-weighting. As such, each author, not each article, represented one data point. Each author in each article was coded by their country of their institutional affiliation; afterwards, the countries were grouped into general regions: the United States (U.S.), Canada, the United Kingdom (UK)/New Zealand (NZ)/Australia (AUS), Europe, Asia, Latin America and Africa. The UK was scored separately from mainland Europe as mainland Europe is a mixture of many different languages. Due to cultural and linguistic similarities, New Zealand and Australia were included in the same geographical category as the UK, and identified as UK/NZ/AUS.
