Table 4.

Correlation coefficients between attention task outcome measures as in Table 3 and the Wechsler Abbreviated Scale of Intelligence (WASI) Perceptual Reasoning Index (PRI) and serial recall principal components.

Attention metric	WASI PRI	Serial recall ability	Vocoder sensitivity
Color–shape categorization RT difference	−.21	−.24	−.10
Stroop incongruent–congruent RT difference	−.21	−.09	.21
Stroop incongruent–neutral RT difference	−.30	−.30	.17
TOVA Response Time CNS	−.32	−.12	.10
TOVA Variability CNS	−.18	.04	−.01
TOVA Commission CNS	.22	.12	−.11
TOVA Omission CNS	−.09	−.17	−.13

Note. No correlations were significant at the p < .05 level. RT = reaction time; TOVA = Test of Variables of Attention; CNS = comparisons to normative samples.
