Recent theories of text comprehension assume that readers build a represent
ation of the situation described by a text additon to a representation of t
he text itself. This level of representation, the situation model, is consi
dered tantamount to deep comprehension of the text. This paper gives an ove
rview of the empirical results concerning the role of situation models in t
ext comprehension. The description is guided by a number of questions, name
ly, what information is represented in situation models, and what the preco
nditions for building a situation model are, Moreover, effects of situation
models on processes involved in text comprehension as well as the represen
tational format of situation models are discussed. Finally, problems and op
en questions regarding research on situation models are mentioned, and dire
ctions for further research are suggested.
