Figure 2 .

Individual z scores for adult word count and conversational turn count are shown with respect to the natural language study (NLS)-Age sample in the left panel and the NLS-Age/socioeconomic (SES) status sample in the right panel. The solid line indicates mean performance of each sample. Dashed lines indicate the range from +1 to −1 standard deviations from the NLS mean, typically understood as within the average range. Hard-of-hearing (HH) and normal-hearing (NH) children are plotted in triangle and diamond markers, respectively. AWC = adult word count; CTC = conversational turn count.
