Correlations between mismatch indices and behavioral measures

Small deviant mismatch indices	Frequency discrimination skilla (N = 62)	Nonword repetition (N = 61)
Tones MMN mean amplitude	0.024	0.046
Tones LDN mean amplitude	−0.044	−0.018
Tones ITC 0–300 ms, 4–7 Hz	0.114	0
Tones ERSP 300–600 ms, 4–7 Hz	0.099	−0.217
Syllables MMN mean amplitude	−0.218	0.007
Syllables LDN mean amplitude	0.243	−0.094
Syllables ITC 0–300 ms, 4–7 Hz	0.010	0.113
Syllables ERSP 300–600 ms, 4–7 Hz	−0.138	−0.400

Correlation of 0.37 or more is significant at Bonferroni-corrected level of 0.05/16.

^aThresholds inverted so that a positive correlation means good skill corresponding to positive mismatch index.
