This report presents evidence suggesting that the phoneme-based approach taken by Romani, Galuzzi, Guariglia, and Goslin (Comparing phoneme frequency, age of acquisition, and loss in aphasia: Implications for phonological universals. Cognitive Neuropsychology, this issue) falls short of capturing the complexity of articulation planning in patients with apraxia of speech. Empirical and modelling data are reported to demonstrate that the apraxic pathomechanism resides in the hierarchical architecture of phonological words rather than in the context-independent properties of phonemes. Because the factors determining complexity of articulation planning are interlaced between gestural, syllabic, and metrical levels, they cannot be captured by markedness rankings limited to any of these levels.
本报告提供的证据表明，Romani、Galuzzi、Guariglia 和 Goslin（《比较失语症中语音频率、获得年龄和丧失：语音普遍性的启示》，认知神经心理学，本期）所采用的基于音位的方法未能捕捉到言语失用症患者发音规划的复杂性。报告了实证和建模数据，以证明运动性言语失用症的病理机制存在于音位词的层次结构中，而不是在音位的独立于语境的特性中。由于决定发音规划复杂性的因素交织在手势、音节和韵律层面之间，因此它们无法通过仅限于任何这些层面的标记等级来捕捉。
