The time course of contextual influences during lexical ambiguity resolution: Evidence from distributional analyses of fixation durations.

In the lexical ambiguity literature, it is well-established that readers experience processing difficulties when they encounter biased homographs in a subordinate-instantiating prior context (i.e., the subordinate bias effect).

Sumario:In the lexical ambiguity literature, it is well-established that readers experience processing difficulties when they encounter biased homographs in a subordinate-instantiating prior context (i.e., the subordinate bias effect). To investigate the time course of this effect, the present study examined distributional analyses of first-fixation durations on 60 biased homographs that were each read twice: once in a subordinate-instantiating context and once in a dominant-instantiating context. Ex-Gaussian fitting revealed that the subordinate context distribution was shifted to the right of the dominant context distribution, with no significant contextual differences in the degree of skew. In addition, a survival analysis technique showed a significant influence of the subordinate versus dominant contextual manipulation as early as 139 ms from the start of fixation. These results indicate that the contextual manipulation had a fast-acting influence on the majority of fixation durations, which is consistent with the reordered access model's assumption that prior context can affect the lexical access stage of reading.
