The literature of educational psychology and the literature used by writers in educational psychology

Using Psychological Abstracts as the source of the original sample (“first-level”), various characteristics of the literature of educational psychology are compared with the characteristics of a “second-level” literature (defined as the literature that the first level cites). In particular, the scatter (dispersion) of periodical articles over periodical titles is looked at for both levels. The journals most cited within the literature of educational psychology are identified.
