Oral ability to recognize forms and oral motor ability were examined in twenty children, aged 11 years, with normal occlusion. In the RF-test (recognition of form) the children identified the test pieces quicker but with a higher frequency of misidentification of the test pieces than a group of 17-year-old boys studied earlier. The effect of learning on the children was substantial with much quicker and greater certainty from one examination to another. Identification time and misidentification were positively correlated (individuals with long identification time also had a high frequency of errors). In the MA-test (oral motor ability) the children required a longer time to assemble the halves of the test pieces than did 17-year-old boys. A considerable effect of learning was found in the MA-test. The results of the RF-test and the MA-test varied independently of each other for which reason the two tests measure different components of oral ability.
对20名11岁咬合正常的儿童进行了口腔形式识别能力和口腔运动能力测试。在RF测试（形式识别）中，这些儿童识别测试片的速度更快，但与之前研究的一组17岁男孩相比，测试片误识别的频率更高。学习对儿童的影响很大，从一次测试到另一次测试，识别速度更快且确定性更高。识别时间和误识别呈正相关（识别时间长的个体错误频率也高）。在MA测试（口腔运动能力）中，儿童将测试片的两半组装起来所需的时间比17岁男孩长。在MA测试中发现了显著的学习效果。RF测试和MA测试的结果相互独立变化，因此这两项测试测量的是口腔能力的不同组成部分。
