To validate the self-report measure of sensitivity, we correlated the threshold (M = 21.14 dB SPL, SD = 1.93) with ATQ orienting sensitivity. The threshold had a moderate negative relationship with orienting sensitivity, r = -0.31, p = 0.006. The Supplementary Material provides a full matrix of the uncorrected correlations between all ATQ scales (Supplementary Table 1) and subscales (Supplementary Table 2) and the threshold. It also provides a table with descriptive statistics for the ATQ (sub)scales (Supplementary Table 3).
