Table 3.

Serial subtraction differences between memory groups.

Normal memory function (n = 41) Poor memory function (n = 35) p-Values
Serial subtraction ST habitual (# correct) 3.1 (1.7) 3.4 (1.6) p = .48
Serial subtraction ST fast (# correct) 3.2 (1.5) 2.8 (1.8) p = .32
Serial subtraction DT habitual (# correct) 4.5 (2.6) 3.8 (2.1) p = .21
Serial subtraction DT fast (# correct) 4.4 (2.0) 3.2 (2.3) p = .03
Serial subtraction DT habitual (#correct/sec) 0.50 (0.29) 0.36 (0.21) p = .02
Serial subtraction DT fast (#correct/sec) 0.57 (0.25) 0.34 (0.22) p < .001

Note. ST = single task; serial subtraction only; DT = dual task; serial subtraction accuracy during motor task. Values reported as means (SD).
