Strategic reading requires not only a repertoire of processing strateg
ies but also knowledge about the conditions under which a given strate
gy is relevant. This study examined college students' conditional know
ledge about reading. Subjects sorted descriptions of reading situation
s according to how they believe they read in each situation. Cluster a
nalyses of the resulting distance matrixes identified 10 distinct cate
gories of reading situations. Ratings of the cognitive demands of the
reading situations supported the interpretations of the sorting data a
nd suggested how reading patterns vary across different texts and task
demands. The 10 distinct reading categories constitute a first approx
imation to a typology of reading situations that may serve as a framew
ork for organizing research on reading strategies.
