Dyslexics displayed longer MMN latency than controls for all linguistic contrasts and for vowel duration deviants, as well as for the frequency deviants in pure tones.

WebSep 1, 2024 · Source localization studies have shown that MMN generators for each acoustic deviant feature have different cortical generators (Giard et al. 1990; Garrido et al. 2009), which may help explain findings with pitch, but not duration deviants. Current results suggest that tDCS seems to have a variable effect on the different generators.

The deviants were otherwise identical to standards. Sound intensity was 56 dB SPL at the subject‘s head.
WebSubjects were presented 1600 binaural tone pips (3/second) comprising 1520 standards (75 dB, 1 kHz, 100 ms duration, 10 ms rise/fall) and 80 pitch-deviants (75 dB, 1.2 kHz, 100 ms duration, 10 ms rise/fall).

Specifically, we presented either two simultaneous melodies or two simultaneous repeating tones, one higher and the other lower in pitch (2–6).In each case, on 25% of trials, a pitch deviant was introduced in the higher voice and, on 25% of …
WebWe presented a duration deviant and a pitch/duration deviant in this study. Literature has shown that duration MMN was more robust in separating controls from schizophrenia patients than pitch MMN (e.g., Magno et al. 2008). Duration deviant was therefore our primary task. At the mean time, we explored whether one version of the duration/pitch ...
