The study describes the mechanisms of visual text processing when various types of errors in oral reading occur. The paper presents the results of an experiment with 10 Russian speakers who read two texts in Russian aloud, while their eye movements were being recorded. The two main types of speech errors under consideration were self-corrections and unnoticed errors. The results indicate that the patterns of eye movements associated with the effects of late visual processing differ depending on the type of error. In the case of self-corrections, more regressions to the word where the error occurred, and from the next word to the previous one were observed. Furthermore, in general, it takes more time to read words with an error which was noticed and corrected. No differences were found in the effects of early processing of both the words with self-corrections and unnoticed errors. Presumably, the process of self-correction begins during the visual processing of the word following the erroneous one.
