Differences In Citation Personal Display: Does It Exist In Three Social Science Disciplines?

Based on researchers' personal websites, the extents of citation personal display (CPD) in three disciplines of social science (economics, sociology, and psychology) are investigated. Eight universities in the U.S. are targeted according to the 2016 US News & World Report ranking by subject. Results show that the overall level of CPD in social science is not high (7.5%), and researchers in psychology have the highest level of CPD (8.3%), followed by economics and sociology, which means that CPD does not behave the same in three disciplines. Furthermore, the present work suggests that researchers in different universities indeed have differences in CPD when controlling them in the same disciplines, embodying in that the statistically significant differences on CPD exist in economics and psychology, yet differences between universities are insignificant in sociology.
