This bibliography is a continuation of those published by Berry and Daniel (1984, 1985), Daniel (1981a, 1981b), Fulkerson and Wise (1987), Fulkerson, Wise, and Ancelet (1988), Johnson and Daniel (1974), Morgan and Daniel (1983), Mosely and Daniel (1982), and Wise and Fulkerson (1986, 1989). Search methods, criteria for inclusion, and other considerations were similar to those used previously. We also continued the cumulative numbering practice of previous bibliographies. We included a number of pre-1989 citations not listed in previous bibliographies, because we continue to terminate our search in June. A noteworthy observation about this year's bibliography concerns the increase in the number of cognitive psychology articles, many of which are difficult to separate from the teaching of psychology.
