Più mosso (más rápido): El automovimiento rápido acelera la acción cíclica en la realidad virtual

Visually induced self-motion (vection) affects the speed at which actions are performed. However, it has been unclear whether this speedy action induced by vection is based on the modulation of mental tempo. To clarify this issue, we tested whether the speed of vection infuenced an observer’s cyclic action related to mental tempo. Observers viewed fast and slow moving optic fow stimuli and dynamic random dots, whilst handclapping at their preferred tempo. The results revealed that the clapping rate was the fastest in the fastest optic fow condition. This effect vanished when optic fow stimuli moved fast but did not induce vection. Fast optic fow stimuli also induced larger pupil dilation, suggesting that it increased the observer’s arousal level. These results suggest that illusory self-motion increased arousal levels, thereby modulating mental tempo.
