This article reports the results of a study of the role of individual diffe
rences in Internet searching. The dimensions of individual differences form
ing the focus of the research consisted of: cognitive styles; levels of pri
or experience; Internet perceptions; study approaches; age; and gender. Six
ty-nine Masters students searched for information on a prescribed topic usi
ng the AltaVista search engine. Results were assessed using simple binary r
elevance judgements. Factor analysis and multiple regression revealed inter
esting differences, retrieval effectiveness being linked to: male gender, l
ow cognitive complexity; an imager (as opposed to verbalizer) cognitive sty
le; and a number of Internet perceptions and study approaches grouped here
as indicating low self-efficacy. The implications of these findings for sys
tem development and for future research are discussed.
