Comparison of current-study JNDs to JNDs from previous studies with highly trained subjects. Current-study thresholds (○) are compared to thresholds from Hawkins and Wightman (1980, ◻), Koehnke et al. (1986, △), Smoski and Trahiotis (1986, +), Gabriel et al. (1992, ×), Smith-Olinde et al. (1998, *). Data points for NH listeners from Gabriel et al. (1992) and Smith-Olinde et al. (1998) studies are plotted as means from the set of listeners.
