The aim of the present study was to investigate the effects of these attention dynamics on speech perception in adults, children with typical hearing (TH) and children with cochlear implants (CIs).</p><p><strong>Design: </strong>Twenty-seven adults with TH (mean age 20.8 years), 24 children with TH (mean age 10.6 years), and 8 children with CIs (mean age 10.1 years) were tested on a speech understanding in noise task using AVATAR, a realistic audiovisual paradigm. Participants were asked to repeat the sentence as closely as possible. In one task, participants performed an adaptive speech-in-noise task to determine speech reception thresholds for sentences recorded by a male and a female speaker. In the second task, both male and female speakers could speak simultaneously in controlled conditions that required participants to either switch attention from one to another or maintain attention on the first. Eye-tracking data were collected concomitantly with both listening tasks, providing pupillometry and gaze behavior data.

In addition, pupillometry data showed that children with CIs exerted more listening effort in the single-talker task.
