Correlation between the MMN mean amplitude over the left hemisphere electrodes (F3, C3, P3) in response to non-native phoneme at the age of 1 year and the number of words produced by the children at the age of 2 years. Correlations are over both groups. Horizontal line is the MMN mean amplitude over the left hemisphere electrodes, vertical line the number of words produced by each child as shown by the MacArthur Communicative Development Inventories (CDI). The result showed that the more negative the mean amplitude indicating better discrimination of non-native phoneme, the less the child produced words at the age of two years.
