The sense of body ownership influences decision making and motor performance. The SPECS Research Group, led by ICREA Professor Paul Verschure, has conducted a study published recently in Scientific Reports that demonstrates this relationship through behavioural experiments with healthy individuals.

Visuotactile integration modulates motor performance in a perceptual decision-making task

June 13th, 2017|Categories: News|

Here, we investigate the specific question of whether experimentally induced ownership over a virtual limb can modulate the performance of that limb in a simple sensorimotor task. Using a Virtual reality (VR) environment we modulate body ownership in three experimental conditions with respect to the (in)congruence of stimulus configurations. Our results show that the degree of ownership directly modulates motor performance. This implies that body ownership is not exclusively a perceptual and/or subjective multimodal state but that it is tightly coupled to systems for decision-making and motor control.
