Table 3.

Correlation coefficients (p-values) between speech sound accuracy (Percent Consonants Correct-Late 8) and average gray and white matter values in the regions in which the two groups differed

	L-STG gray	R-STG gray	CC white	R-LOG white
PCC-Late 8	-.37 (.001)	-.28 (.013)	-.31 (.006)	.449 (<. 001)
LSTG gray		.63 (<.001)	.07 (.52)	-.19 (.106)
RSTG gray			.01 (.98)	-.24 (.035)
CC white				-.11 (.331)
Nonparametric correlations for Speech Sound Error Group only (n=23):
PCC-Late 8	.00 (.98)	.22 (.31)	.08 (.72)	.32 (.14)

Note: Values in the top of the table reflect Pearson correlations based on n=54 TS and n=23 SSE participants. Values in the bottom row reflect the nonparametric (Spearman’s rho) correlation coefficient for PCC-Late 8 values for only the SSE group. p-values are listed in parentheses. PCC-Late 8=Percent consonants correct-late 8; L-STG=Left superior temporal gyrus; R-STG=Right superior temporal gyrus; CC=Corpus callosum; R-LOG= Right lateral occipital gyrus; SSE=Speech sound error.
