本研究探讨了儿童和成人产生抑扬格和扬抑格韵律形式的运动过程。记录下唇运动，同时16名年龄在3岁、10岁和4岁之间的儿童、9名（岁;月）和8名成人产生抑扬格（例如，[pe<$p^p]）和扬抑（例如，'p ^pep]）nonce words.对于儿童和成人来说，抑扬格和扬抑格词的运动模式是有区别的，但在性质上是不同的。最值得注意的是，儿童不产生振幅调制形式的扬抑音，也许反映了依赖于早期发展的节奏模式，如那些在规范的咿呀学语。相比之下，对应于Iambs的运动被很好地调制，并且对于两组扬声器特别稳定，这表明它们需要增加运动特异性。看来，韵律形式是在知觉和语言上建立起来的，儿童在他或她现有的运动技能中找到了可用的手段，以产生与抑扬格和扬抑格相对应的充分分化的运动。
The present study investigates motor processes underlying the production of iambic and trochaic metrical forms for children and adults. Lower lip movement was recorded while 16 children between the ages of 3;10 and 4;9 (years; months) and 8 adults produced iambic (e.g., [pép^p]) and trochaic (e.g., ['p^pep]) nonce words. For both children and adults, movement patterns for iambic and trochaic words are well differentiated, but in qualitatively different ways. Most notably, children do not produce amplitude modulated forms for trochees, perhaps reflecting a reliance on early developing rhythmic patterns such as those seen in canonical babbling. In contrast, movements corresponding to iambs are well modulated and particularly stable for both groups of speakers, suggesting that they require increased movement specificity. It appears that metrical forms are perceptually and linguistically established and that the child finds the means available within his or her existent motor repertoire to produce adequately differentiated movements corresponding with iambs and trochees.
