Abstract: Previous studies demonstrated that Eysenck was one of the most cited authors in psychological literature. Studies in question were not concerned exclusively with Eysenck's citations. All one can recognize from their results about Eysenck himself is his citation rate in various citing sources and various observed periods.
The purpose of this study was to look beyond Eysenck's citation figures. The intention was to describe his cited publications in terms of type and age and to rank his citing journals and co-cited authors, so as to disclose the nature of his impact in general, and in East Europe and Yugoslavia in particular. All references from articles citing H.J. Eysenck as first author and referred in Social Science Citation Index from 1992 to 1996 and in the SocioFakt, a Yugoslav bibliographic database, from 1981 to 1996, were submitted to citation and co-citation analysis.
The results show that most cited Eysenck's works are those published in seventies. Half-life and variance of his citations (Mdn=18, rng=18) is far above those normally met in psychological journals, indicating vitality of his early findings and theories. Unlike other distinguished personality theorists who are also test-makers Eysenck is cited more by books and chapters (44.2%) than by manuals (28%), although the share of articles in his citation rate is also relatively high (27.8%). P. Costa, R. McCrae, M. Zuckerman, D. Watson, and R.B. Cattell are most often cited with Eysenck. This and other rank lists suggest that Eysenck is dominantly cited in articles dealing with personality and clinical psychology, though his influence reaches practically all broad fields of psychology, except sensation and perception. Finally the results indicate that Eysenck is cited relatively more outside USA, and by East European and Yugoslav authors then in general.
In conclusion, results show that Eysenck's citation rate is polyvalent in terms of both his cited and citing sources. Consequently his impact is far reaching in both geographic and structural sense.
