Abstract
People frequently coordinate their motor behavior in daily life, and stability of this joint motor performance is crucial for successful implementation of many tasks (e.g., passing a glass of water, care-giver interactions with patients, etc.). When a person executes a task alone, the central nervous system coordinates redundant sets of elements to stabilize task performance. However, when two persons share a task, their nervous systems can only interact via sensory feedback. Thus, it is unclear whether similar coordination strategy may be facilitated in these situations. I will discuss recent projects exploring performance–stabilizing synergies in motor tasks involving two actors, including accurate multi-finger force production and prehension tasks.
