Listeners adapt to diverse cues in real-time language processing. While younger adults can learn and adapt in complex multitalker settings, it remains uncertain whether this ability persists in older adults, especially when they must accumulate auditory inputs to learn novel statistics. We examined whether older adults adapt to talker-specific patterns using paralinguistic cues such as disfluency. In two experiments, older adults listened to instructions from two talkers: one used disfluency predictively (e.g., always referring to novel objects following disfluency) and the other used disfluency unpredictably (e.g., referring to either familiar or novel objects following disfluency). Experiment 1 examined a single-talker setting (
