TABLE 2.

Intercorrelations obtained in Experiment 1 between WISC forward digit span, memory game conditions, and WISC backward digit span.

Cochlear Implant Group N = 43 (Subgroup Values in Parentheses, N = 22)
		Memory Game
	WISC Forward Digit Span	Color-Names-Plus-Lights	Lights-Only
Memory game
Color-names-plus-lights	0.09 (0.14)	—
Lights-only	–0.02 (–0.07)	0.71** (0.60**)	—
WISC backward digit span	0.52** (0.47*)	0.46** (0.50*)	0.48** (0.57**)

Normal-Hearing Group N = 44 (Subgroup Values in Parentheses, N = 22)
		Memory Game
	WISC Forward Digit Span	Color-Names-Plus-Lights	Lights-Only
Memory game
Color-names-plus-lights	0.58** (0.54*)	—
Lights-only	0.01 (0.03)	0.20 (0.30)	—
WISC backward digit span	0.32* (0.08)	0.36* (0.52*)	0.19 (0.22)

^*p < 0.05

^**p < 0.01.

Although age in months has been partialled out of the calculations, age showed only a small positive correlation in the normal-hearing group and a near-zero correlation in the cochlear implant group, making the simple correlations almost identical to those shown above.
