Left-and right-handed human males and females were tested in an experimental analog of free-field observational studies which had demonstrated rotation (turning) biases in both rats and humans. When required to rotate through exactly twice 360 degrees clockwise (rightwards) or anticlockwise (leftwards) with reduced sensory input, dextrals, especially females, showed a rightwards bias and sinistrals a leftwards tendency. When attempting, blindfolded, to walk in a straight line, all four groups of subjects deviated to the right, though the effect was again slightly, and nonsignificantly, larger for females and dextrals. These lateral biases may relate to dopamine asymmetries in the basal gangalia.
对惯用右手和左手的男性及女性进行了一项自由场观察研究的实验模拟测试，该研究已证明大鼠和人类都存在旋转（转向）偏向。当要求在感觉输入减少的情况下顺时针（向右）或逆时针（向左）精确旋转两圈360度时，右利手者，尤其是女性，表现出向右的偏向，而左利手者则有向左的倾向。当蒙住眼睛试图直线行走时，所有四组受试者都向右偏离，不过女性和右利手者的这种效应再次略大，但不显著。这些侧向偏向可能与基底神经节中的多巴胺不对称有关。
