An empirical update (1969-1989) of D. L. Krantz's thesis that the experimental analysis of behavior is isolated.

Citation data from 1970 to 1989 were examined in order to determine whether the "isolation" of the experimental analysis of behavior (EAB) that was originally documented by Krantz (1971, 1972) has persisted beyond the early 1970s. Our findings from analyses of the Journal of the Experimental Analysis of Behavior (JEAB) and of related journals support the following conclusions: (1) In the 20-year period since 1969, JEAB has continued to cite its own articles ("self-cite") at a higher rate than related journals; (2) JEAB's self-citation rate decreased by a larger amount since 1969 than did that of related journals; and (3) JEAB was cited with diminishing frequency by some related journals during the 20-year period. These findings and other disciplinary comparisons provide information relevant to the issue of the health of behavior analysis and related specialties.
