本研究采用纸笔测验的方法，以卡通人物为被试，对左右辨别能力进行了研究。该测试包括一个人的线条画，没有，一个或两个手臂穿过图中身体的垂直轴。受试者的任务是用铅笔尽可能快地在图中的右手或左手上做记号。从后面、从前面或在后面和前面视图之间随机交替查看线条图。进行了两项研究。第一组由393名成年人组成：153名男性和240名女性; 338名右撇子和55名左撇子。结果表明，男性的表现优于女性。左撇子和右撇子表现同样出色。然而，左撇子男性的表现比右撇子男性好。右撇子和左撇子女性之间的表现没有差异。第二项研究由175名右撇子大学生组成：63名心理学学生，54名医学生和58名法律学生。主要的发现是，医学生比心理学的学生表现更好的所有图形方向的子测试和所有的手臂位置。与法律系学生相比，医学系学生在后视图分测验上表现相同，但在前视图分测验上表现更好，在交替视图分测验上，他们在三个手臂位置中的两个上表现更好。
The present study investigated right-left discrimination, with a paper-and-pen test with cartoon figures. The test consisted of line drawings of a person with no, one, or both arms crossing the vertical axis of the body in the figure. The subjects' task was to mark with a pencil, as fast as possible, which was the right or left hand in the figure. The line drawings were viewed from the back, from the front, or randomly alternating between the back and front views. Two studies were conducted. The first consisted of 393 adults: 153 males and 240 females; 338 right-handers and 55 left-handers. The results showed that the males performed better than the females. The left-handers and the right-handers performed equally well. However, the left-handed males performed better than the right-handed males. There was no difference in performance between the right-handed and the left-handed females. The second study consisted of 175 right-handed college students: 63 psychology students, 54 medical students, and 58 law students. The main finding was that the medical students performed better than the psychology students for all figure orientation subtests and for all arm positions. In comparison with the law students, the medical students performed at the same level on the back view subtest, but they performed better on the front view subtest and on two out of three arm positions on the alternating view subtest.
