Reach-to-grasp actions are the outcomes of several voluntary sub-movements (Jeannerod, 1981, 1984; Paulignan et al., 1997) dependent on the object intrinsic position and shape characteristics (Fattori et al., 2009). The behaviors implemented in order to achieve the proximal goal (i.e., grasping) are further modulated by the action one wants to perform once the object has been grasped (distal go...

Acallosal and callosotomized subjects usually show impairments on tasks requiring bilateral interdependent motor control. However, few studies have assessed the ability of these subjects to learn a skill that requires the simultaneous contribution of each hemisphere in its acquisition. The present study examined whether acallosal and callosotomized subjects could learn a visuomotor skill that i...

An asymmetry in the prevalence of left-handedness vs. right-handedness society has supposedly resulted negative frequency-dependent advantages for left-handers interactive sports. The aim this study was to test whether these apply handball by examining being left-handed is beneficial when executing 7 m shots, a highly unimanual movement. All 1,625 shots at men’s 2016–2022 European championships...

Decision making and reinforcement learning over movements suffer from the curse of dimensionality: the space of possible movements is too vast to search or even represent in its entirety. When actions involve only a single effector, this problem can be ameliorated by considering that effector separately; accordingly, the brain's sensorimotor systems can subdivide choice by representing values a...
