Abstract The human brain extracts statistical regularities from the surrounding environment in a process referred to as learning. Recent behavioural evidence suggests that developmental dyslexia affects However, surprisingly few neurophysiological studies have assessed how neural processing underlying In this study, we used electroencephalography explore correlates of an important aspect learning – sensitivity transitional probabilities individuals with dyslexia. Adults diagnosed (n = 17) and controls 19) were exposed continuous stream sound triplets which triplet endings location deviants (i.e., presented unexpected speaker direction) or had low probability given triplet’s first two sounds). Location elicited large mismatch negativity (MMN), was larger than dyslexics. Statistical small, yet significant MMN (sMMN) controls, whereas dyslexic did not exhibit MMN. These results suggest mechanisms are impaired Significance statement We deviants, namely word (as compared high transitions) MMN,
