Table 2.

Mismatch negativity amplitude (in μV) from block 1 averaged across nine sites (Fz, FCz, Cz, F3, F4, FC3, FC4, C3, C4).

Duration type	n	MMN amplitude: mean and CI
		[a]		[ɑ]
Long	9	-1.714	(-2.357…-1.070)	-1.034	(-1.663…-0.406)
Short	9	-0.972	(-1.615…-0.329)	-0.676	(-1.305…-0.047)
Average across long and short	18	-1.343	(-1.798…-0.888)	-0.855	(-1.300…-0.411)

The table shows means and 95% confidence intervals (CIs) per vowel-quality and duration-type, and the number of subjects (n) in each group.
