This investigation examined the existence of interconnectedness between developing linguistic subsystems. Spontaneous speech samples were collected from 31 typically-developing Greek-speaking toddlers across two age levels, at 28 and 36 months. Correlational analyses were performed synchronically and predictively, revealing significant positive relationships among all language skills within ages. Phonetic and grammatical skills also showed predictive value for later skills. In addition, a cluster analysis on the basis of performance on each individual skill revealed variable linguistic profiles: Low performers showed multiple interactions within and across ages, while High performers showed minimal such interactions. The current results revealed complex interdependencies among the different language skills with children exhibiting variable linguistic profiles, as supported by dynamic systems theory approaches to language acquisition.

这项调查检验了发展中的语言子系统之间是否存在相互关联。自发语音样本是从 28 个月和 36 个月大的两个年龄阶段的 31 名典型的希腊语幼儿中收集的。相关分析是同步和预测性地进行的，揭示了各个年龄段所有语言技能之间的显着正相关关系。语音和语法技能也显示出对以后技能的预测价值。此外，基于每项技能表现的聚类分析揭示了不同的语言特征：低表现者在年龄内和跨年龄表现出多种互动，而高表现者则表现出最少的此类互动。
