25个年轻人的能力进行了测试，以区分尺寸。将10 mm的参考棒放置在牙齿之间，与不同高度的测试棒交替。在应用参考棒之后，要求受试者最大程度地张开嘴。将测试棒放置在下门牙上，受试者慢慢地闭上嘴，直到他们的上门牙接触测试棒。然后，受试者被要求评估测试棒是否感觉高于或低于参考棒。使用这种实验方法，发现不正确的评估对称地分布在10 mm参考棒周围。提出了一种受体机制，并应用于解释本实验和以前的实验结果。
The ability of twenty-five young persons to discriminate dimensions was tested. A reference stick of 10 mm was placed between the teeth, alternating with test sticks of different heights. After application of the reference stick the subjects were asked to open the mouth maximally. A test stick was placed on the lower incisors and the subjects closed the mouth slowly, until their upper incisors contacted the test stick. The subjects were then asked to assess whether a test stick felt higher or lower than the reference stick. Using this experimental method, it was found that incorrect assessments were symmetrically distributed around the 10 mm reference stick. A receptor mechanism is proposed, and applied to explain the results of the present and a previous experiment.
