音系复杂性可能是人类语言本质的核心。它可能影响语言中音素和音素序列的分布，还决定习得年龄以及在失语症中丧失的易感性。我们利用从一个意大利语音系转写词库（phonitalia，可在phonitalia.org获取）得出的频率统计数据、音素习得年龄（AoA）排名以及言语失用症（AoS）患者的音素错误率（作为发音复杂性的一个指标）来评估这一论断。这些测量指标与跨语言得出的标记性排名相关。我们发现了很强的对应关系。然而，AoA可由失用性错误和频率共同预测，这表明这些变量有独立的作用。我们的研究结果支持复杂性普遍原则的真实性。此外，这些结果表明这些复杂性原则有发音基础，因为它们调节言语失用症患者的语言产出，但不调节有更核心音系困难的患者的语言产出。
Phonological complexity may be central to the nature of human language. It may shape the distribution of phonemes and phoneme sequences within languages, but also determine age of acquisition and susceptibility to loss in aphasia. We evaluated this claim using frequency statistics derived from a corpus of phonologically transcribed Italian words (phonitalia, available at phonitalia,org), rankings of phoneme age of acquisition (AoA) and rate of phoneme errors in patients with apraxia of speech (AoS) as an indication of articulatory complexity. These measures were related to cross-linguistically derived markedness rankings. We found strong correspondences. AoA, however, was predicted by both apraxic errors and frequency, suggesting independent contributions of these variables. Our results support the reality of universal principles of complexity. In addition they suggest that these complexity principles have articulatory underpinnings since they modulate the production of patients with AoS, but not the production of patients with more central phonological difficulties.
