Relation between pitch strength and mutual information and pattern of their composited z-score. a Individual pitch strength as a function of mutual information. b The composited z-score as a function of individual JND. Fitted curves (solid line) were obtained by fitting the discrete data (filled circles) using the least square method. Data points for individual participants are numbered as given in Table 1. Prediction intervals corresponding to 95% confidence are indicated by the dashed curve
