行动观察已被证明有助于观察者的表现,并越来越多地被用作神经损伤后的康复工具。在对象操作,视觉观察的性能,建议使更新的感觉运动表征的对象属性。在这里,通过3个实验,我们研究了一个新的对象的动作观察更新的对象质量和重量分布的双手操作的效果。在每个实验中,天真的参与者被分成两人一组,并被指定为“表演者”或“观察者”。在实验1和2中,观察者坐在表演者对面。在实验3中,观察者站在表演者身后。两人观察并举起i)实验1中的一个轻或重的盒子,或ii)实验2和3中的一个质量中心左右不均匀的盒子。我们的研究结果表明,行动观察促进更新的对象质量信息,但没有关于重量分布的信息。具体地说,观察者的沉重的箱子随后施加更大的力量和力率在雅阁的质量的箱子。相比之下,表演者和观察者的不均匀的方块有大的峰值卷。我们认为,这表明了观测的鲁棒性,有利于理解物体质量,同时突出了操纵重量分布不均匀的物体的复杂性。
Action observation has been shown to facilitate the performance of the observer and is being increasingly used as a rehabilitation tool following neurological damage. During object manipulation, visual observation of performance is suggested to enable the updating of the sensorimotor representations of object properties. Here, through 3 experiments, we examine the effect of action observation of a novel object on the updating of object mass and weight distribution for bimanual manipulation. For each experiment, naïve participants were allocated into pairs and assigned as the “performer” or “observer”. For experiments 1 and 2, observers sat opposite the performers. For experiment 3, observers stood behind the performer. The pairs observed and lifted either i) a light or heavy box in experiment 1, or ii) a box with a left or right uneven center of mass in experiments 2 and 3. Our results showed that action observation facilitated the updating of object mass information but not information about weight distribution. Specifically, observers of the heavy box subsequently applied larger forces and force rates in accord with the mass of the box. In contrast, both performers and observers of the uneven box had large peak rolls. We suggest that this shows the robustness of observation in facilitating an understanding of object mass while highlighting the complexity of manipulating an object with uneven weight distribution.
