Table 1.
Pearson product-moment correlation coefficients of slopes and constants (of the linear regression ASW = a × IC + b) with participants’ age, binaural TFS threshold and localization precision for each of the three stimulus types. Where appropriate, coefficients are shown for all participants (df = 34) and after the forward slash for those with TFS data (df = 20). Below each main coefficient(s) are the coefficients for partial correlations controlling for the specified covariates (e.g., below the slope-age coefficients for all and just TFS participants are the partial slope-age coefficients controlling for precision and TFS threshold). The number of asterisks (1, 2 or 3) indicates coefficients that were statistically significant at the p < 0.05, 0.01 and 0.001 levels, respectively.
