通过手动控制设备（如轨迹球）来主动探索3D对象的视图，有助于随后的对象识别，这表明运动模拟有助于对象识别。此外，生物力学的限制，如手旋转的范围，可以影响心理旋转。因此，可以用手旋转对象的容易性可以调节通过手动控制的主动探索对对象识别的促进作用。在我们的实验中，参与者进行了两次视图匹配任务，在两者之间执行学习任务。在学习任务中，一组参与者（活跃组）使用他们的手旋转连接到阴极射线管监视器的手柄来观看和探索一个新的3D物体。另一组（被动组）在监视器上观察由主动组参与者操纵的3D物体的运动的重放。主动组的参与者接受了采访，以确定他们认为最容易旋转手的方向。观察概括性能进行了比较前和后的会议。虽然我们在两组中观察到的观点匹配过程中的促进作用，积极组表现出观点依赖性的促进。活动组在会后的观点概括范围在旋转方向上是不对称的。最有趣的是，对于大多数参与者来说，这种不对称的变化对应于最容易旋转手的方向（尺骨偏离）。这些发现表明，物体识别过程可以受到手旋转的影响，这是基于腕关节的生物力学约束。
Active exploration of views of 3-D objects by manually controlling a device, such as a trackball, facilitates subsequent object recognition, suggesting that motor simulation contributes to object recognition. Further, biomechanical constraints, such as range of hand rotation, can affect mental rotation. Thus, the ease with which an object can be rotated by hand may modulate the facilitative effect active exploration through manual control has on object recognition. In our experiment, participants performed two sessions of a view-matching task, with a learning task administered between the two. In the learning task, one group of participants (active group) viewed and explored a novel 3-D object using their hand to rotate a handle attached to a cathode-ray tube monitor. The other group (passive group) observed on the monitor a replay of the movements of the 3-D object as manipulated by an active-group participant. Active-group participants were interviewed to determine the direction they found easiest to rotate their hand. The view-generalization performances were compared between the pre and post sessions. Although we observed a facilitative effect on the view-matching process in both groups, the active group exhibited view-dependent facilitation. The view-generalization range of the active group in the post-session was asymmetric in terms of the rotation direction. Most intriguingly, for most participants, this asymmetric change corresponded to the direction that afforded the easiest hand rotation (ulnar deviation). These findings suggest that the object-recognition process can be affected by ease of hand rotation, which is based on the biomechanical constraints of the wrist joint.
