Dual-task testing

1. Dual-task testing impairs cognitive accuracy in humans.

   “Cognitive accuracy was also higher during the single compared to dual-task condition in the SCD (p < .001) and non-SCD (p = .005) groups.”

1. Dual-task testing impairs motor performance in humans.

   “Slower responses (p = .002) and less accurate (p = .024) and more variable (p = .001) finger tapping were observed during the dual compared to single tasks.”

1. Dual-task testing increases prefrontal cortex oxygenation in humans.

   “Within the SCD group, ∆HbO2 was greater during the dual compared to single cognitive condition (p = .002) and between the SCD and non-SCD groups (p = .016).”
