TABLE 1.
Descriptive statistics for the four auditory timing tasks: Single-interval timing, Metrical pattern discrimination; Tempo contour detection; and the five phonological tasks: Irregular word reading, Word/non-word reading, Non-word reading, Poem reading, Digit span. We report median values and mean absolute deviation (MAD), minimum and maximum, due to a number of deviations from normal distributions, marked by an asterisk next to the median* (Lilliefors Kolmogorov-Smirnoff test, p < .05). 1Note that regularity detection, digit span and Raven's scores are the only measures featuring larger values corresponding to better performance; all others feature smaller values for better performance (auditory: Thresholds; phonological and literacy: Number or incorrect items)
