TABLE III.
Results of regression analysis on data from all 51 participants. Dependent variables were derived by averaging performance across all SNRs. Predictor variables entered into the equation were age, high-frequency pure-tone average (HFPTA), the composite score derived from three of the cognitive tasks (Cog), and performance on the Connections task (Con).
