Sanford, Garrod & Bell(1979) varied the context biases prior to the anaphora sentences and compared the reading time for the general-term anaphora sentences with that for the instance-anaphora sentences. The hypothesis predicts a significant interaction between context biases and the types of anaphoras, but the results failed to confirm this prediction. The present study was conducted to test whether their results had been due to some insufficiences in producing relevant context biases. In this study it was predicted that with relevant and sufficient context biasing instantiation of general-term can be obtained. In experiment 1 and 2, using Lexical Decision Task, an interaction between context biases and types of anaphoras was obtained. This result suggests that Sanford et al's results were due to the difference in situation models generated by the context in the sentences prior to the target sentences with anaphoric subjects. In experiment 3, when the difference due to these situational models was controlled out, a significant interaction between contexts and the types of anaphora was obtained, which supports the instantiation hypotheses, In experiment 4, it was found that the consistency between the context bias prior to the anaphora sentences and in the anaphora sentences facilitates the processing of instantiation.
