Age-Related Interference between the Selection of Input-Output Modality Mappings and Postural Control-a Pilot Study.

In addition, all main effects were more pronounced in old participants: they had stronger performance decrements in cognitive dual tasks compared to single tasks [difference between dual tasks and single tasks: old: M = 0.33; SE = 0.05; young: M = 0.09; SE = 0.02; difference between age groups: t (19) = 4.01, p < 0.001, d = 1.75], for modality incompatible compared to modality compatible tasks [difference between modality incompatible and modality compatible tasks; old: M = 0.21; SE = 0.02; young: M = 0.05; SE = 0.02; difference between age groups: t (19) = 4.93, p < 0.001, d = 2.15] and marginally significant higher decrements during standing compared to sitting [difference between standing and sitting: old: M = 0.07; SE = 0.02; young: M = 0.03; SE = 0.02; difference between age groups: t (19) = 1.87, p = 0.077, d = 0.82].
