A preprint study published January 17, 2026 on bioRxiv reveals that adults who experience dyslexia patterns show measurable differences in how their brains process and predict temporal patterns in sounds. Researchers from Université Claude Bernard Lyon 1 and collaborating French universities found that when listening to rhythmic tone sequences, participants developing reading skills differently showed reduced ability to anticipate when the next sound would occur—even when the rhythm was highly predictable.

The study used an auditory task where participants identified target tones within sequences that varied in rhythmic regularity. While typical readers responded faster when patterns were predictable, those with reading differences showed minimal improvement with predictable rhythms. The researchers noted this suggests “altered temporal prediction abilities” that may affect how the brain processes the timing and rhythm inherent in spoken language.
