This study investigated lower-lip motor processes underlying production of iambic and trochaic metrical forms with 16 children (ages 3 and 4) and eight adults. Movement patterns were well differentiated for both groups but in qualitatively different ways. Results suggest that metrical forms are perceptually and linguistically established.…

Motor control has long been associated with language skill, in deficits, both acquired and developmental, and in typical development. Most evidence comes from limb praxis however; the link between oral motor control and speech and language has been neglected, despite the fact that most language users talk with their mouths. Oral motor control is…

Data from 30 national service centers found the number of assessment instruments endorsed increased as centers adopted a multidisciplinary approach to education and treatment, the largest proportion of instruments fell within intellectual, motor, and language/communication domains, and instruments were used most frequently for diagnostic and…

Lip and jaw movements were studied longitudinally in 19-month-old children as they acquired the voicing contrast for /p/ and /b/. A movement tracking system obtained lip and jaw kinematics as participants produced the target utterances /papa/ and /baba/. Laryngeal adjustments were also tracked through acoustically recorded voice onset time (VOT)…

This document presents a detailed review and index of post-1960 modeling-imitation research relevant to the development and education of children. Each research study is described in terms of purpose, independent and dependent variables, task and procedures, model and subject characteristics, materials and results. In addition, an overall model is…
