To some extent, the minor difference between the two sets of topranked topical areas can be attributed to the fact that JAP publishes a broader range of articles, namely those that comprise
the entire field of applied psychology, than does PPsych. In con trast, the convergence in the two sets of data over a 45year period is remarkable, particularly given that our review covers eight editorial teams for JAP and nine editorial teams for PPsych. This convergence provides evidence that both journals serve as sound indicators of common underlying trends in the research produced in the field of INDUSTRIAL AND ORGANIZATIONAL psychology. At the same time, overall counts may mask important underlying longitudinal trends. For example, in JAP, note how the number of articles published in the area of human factors–applied experimental psychology has decreased, especially since 1983. At the same time, note how the number of articles published in the area of work motivation and attitudes has cycled up and (not too far) down over the 45year period, whereas those in the areas of predictors of performance and leader influences have remained relatively constant over time. The area of methodology–psychometric issues has remained unchallenged as the most popular topical area for most of the 45year period, declining only in the past few years (yet still remaining one of the most popular areas).
