Repairing Misperceptions of Words Early in a Sentence is More Effortful Than Repairing Later Words, Especially for Listeners With Cochlear Implants.

ABSTRACT: The process of repairing misperceptions has been identified as a contributor to effortful listening in people who use cochlear implants (CIs). The current study was designed to examine the relative cost of repairing misperceptions at earlier or later parts of a sentence that contained contextual information that could be used to infer words both predictively and retroactively. Misperceptions were enforced at specific times by replacing single words with noise. Changes in pupil dilation were analyzed to track differences in the timing and duration of effort, comparing listeners with typical hearing (TH) or with CIs. Increases in pupil dilation were time-locked to the moment of the missing word, with longer-lasting increases when the missing word was earlier in the sentence. Compared to list
