The present study employed the visual-world paradigm with eyetracking to discriminate between two versions of the reordered access model - namely, whether meaning frequency and context affect (a) speed of lexical access or (b) the relative weight of simultaneously accessed meanings. The time course of lexical access and meaning integration were studied in 3 groups of Russian speaking participants: 36 individuals in control group as well as 16 individuals with non-fluent and 8 with fluent aphasia. The results allow to confirm psychological reality of the first version, since in balanced ambiguous words contextual bias influences the speed of lexical access. In addition, it was found that healthy population and participants with non-fluent aphasia are affected by the contextual bias even after processing information that resolves ambiguity.
