手指-数字反应兼容性测试要求参与者通过用所有10个手指按下10个键中的1个来识别阿拉伯数字。手指-手指映射的方向通过操纵手-手指映射的全局方向以及每只手内的手指-手指映射的方向而变化（在每种情况下，从小手指到大手指，或相反）。从左到右的心理数字线的假设预测，一个完整的从左到右的映射应该更容易，而基于手指计数的表征的假设预测，计数一致的映射应该更容易。结果表明，当所有10个手指都用来回答时，与参与者报告的原型手指计数策略一致的映射比与从左到右取向的心理数字线一致的映射导致更好的表现，无论是手掌向下还是手掌向上的姿势，他们还证明了数手指的策略会影响数字信息的心理表征和处理方式。
Finger-digit response compatibility was tested by asking participants to identify Arabic digits by pressing 1 of 10 keys with all 10 fingers. The direction of the finger-digit mapping was varied by manipulating the global direction of the hand-digit mapping as well as the direction of the finger-digit mapping within each hand (in each case, from small to large digits, or the reverse). The hypothesis of a left-to-right mental number line predicted that a complete left-to-right mapping should be easier whereas the hypothesis of a representation based on finger counting predicted that a counting-congruent mapping should be easier. The results show that when all 10 fingers are used to answer, a mapping congruent with the prototypical finger-counting strategy reported by the participants leads to better performance than does a mapping congruent with a left-to-right oriented mental number line, both in palm-down and palm-up postures of the hands, and they demonstrate that finger-counting strategies influence the way that numerical information is mentally represented and processed.
