Handedness and performance variability as factors influencing mirror movement occurrence

摘要: A finger flexion task was used to investigate the effect of hand preference and performance variability on intensity mirror movement. Right- left-handed subjects were asked maintain target forces, with either their index or small finger, that represented 25, 50, 75% maximum strength capacity for active finger. Greater movement occurred when active, where there greater in performance, while less dominant active. These findings consistent cortical activation explanation motor overflow (Todor & Lazarus, 1986a), suggest is an important factor influencing production. It concluded that, if reflects efficiency underlying control a voluntary task, then refined decreases potential occur. However, it necessary clarify relationship between preference, variability, overflow, perhaps by examining neural pathways involved
