Table 1.

Demographic information, F0 difference limens (DL) in semitones (ST), and MBEA scores for 24 participants (12 amusics and 12 matched controls). Musical training is defined as the number of years of formal musical education. The cutoff for amusia is defined as two standard deviations below the general population mean of 88% correct, that is, approximately 78% correct (Peretz et al., 2003). MBEA scores are listed both globally (all six subtests) and for the pitch subtests only (Scale, Interval, and Contour). Mean values are shown, with standard deviations in parentheses. Bold values indicate between-group differences in two-tailed independent t-tests with p values less than 0.05.
