Twenty-four first- and second-order sentential approximations of four words each were presented auditorily to two groups of eight normal children. Eight first- and eight second-order approximations were spoken at three rates: 90 (slow); 140 (normal); and 175 (fast) words/min. The 48 approximations were randomized and rates altered as necessary so that one group heard the material at a slow rate (90 words/min) of presentation and the other group at a normal rate (140 words/min) of presentation. The results indicated that although presentation rate did not significantly effect auditory perception, speaking rate did. It was concluded that a slow speaking rate can be expected to enhance the perception of low-level linguistic material regardless of the presentation rate, whereas a normal speaking rate would be best for higher level linguistic material.
分别由四个单词组成的24个一阶和二阶句子近似形式以听觉方式呈现给两组正常儿童，每组8名。8个一阶近似形式和8个二阶近似形式以三种语速说出：90（慢）；140（正常）；和175（快）词/分钟。这48个近似形式被随机排列，语速根据需要改变，以便一组以慢语速（90词/分钟）听材料，另一组以正常语速（140词/分钟）听材料。结果表明，虽然呈现速度对听觉感知没有显著影响，但说话速度有影响。得出的结论是，无论呈现速度如何，慢说话速度有望增强对低水平语言材料的感知，而正常说话速度对高水平语言材料最为合适。
