Note. Scores for individual contrasts are the number of correct binary responses in eight trials. Composite scores are in percentage correct after correction for guessing, using Equation 1. ID = identification; Race/ethnicity: W = White/non-Hispanic (n = 20), A = Asian (n = 2), B = Black (n = 2), H = White/Hispanic (n = 6); Gender: F = female (n = 16), M = male (n = 14); House Ear Institute (HEI) connection: a = child of HEI employee (n = 8), b = child of friend of HEI employee (n = 10), c = sibling of HEI patient (n = 6), d = none (n = 6); VH = vowel height; VP = vowel place; CV = consonant voicing; CC = consonant continuance; CPf = pre-alveolar consonant place; CPr = post-alveolar consonant place; re. = relative to.
