Abstract

This study examined whether and to what extent the characteristics of mental models derived from the identical text, which is known to produce a certain type of mental model, are influenced if the subjects are given different task expectations before the reading session. Seventy-one undergraduates read one of the two text genres, descriptive or narrative, that were based on the same underlying spatial configuration and later answered three types of inference questions about spatial information. Each group was instructed to anticipate one of the three types of questions: global perspective questions, spatial orientation questions, or order inference questions. Results indicated that readers constructed a two-dimensional mental model when they anticipated global perspective questions, whereas they built a one-dimensional mental model when they expected order inference questions. The results showed similar data patterns obtained in the previous studies (Ohtsuka, 1990, 1993a, 1993b) where three text genres produced different models without any specific instructions. Therefore, the findings suggest that subjects' different task expectations, at least in part, account for the effect of genre type on mental models. Three appendixes give examples of experimental passages, lists of inference questions, and instructions. Included are one table and six figures.
