In a large rectangular room, 13 blindfolded women attempted to walk in a straight line from one end of the room to a target centered at the other end of the room. On 12 trials, the women walked forward, and on 12 trials they walked backward. On half the trials under each of these conditions, they walked toward the north, and on the other half to the south. Performance errors were highly correlated for northward and southward progression, an indication of good reliability for this veering task. Veering during forward progression was not significantly related to veering during backward progression. Individual consistency in veering was demonstrated in several ways, and approximately half the participants veered in the same direction on nearly all trials. These results indicate that veering should be considered as an additional manifestation of lateral preferences in human motor behavior.
在一个大的长方形房间里，13名蒙住眼睛的女性试图从房间一端沿直线走到位于另一端中心的目标处。在12次试验中，这些女性向前走，在另外12次试验中她们向后走。在每种情况下的一半试验中，她们向北走，另一半试验中她们向南走。向北和向南行进时的表现误差高度相关，这表明这项转向任务具有良好的可靠性。向前行进时的转向与向后行进时的转向没有显著关联。转向的个体一致性通过多种方式得到了证明，并且大约一半的参与者在几乎所有试验中都朝着相同方向转向。这些结果表明，转向应被视为人类运动行为中侧向偏好的另一种表现形式。
