The present study investigates the latent organization of inhibitory control in children aged between 2;3 and 3;0 years. In addition, it explores the relationships between temperament dimensions - social orientation, motor activity, and attention -, inhibitory control and language. One-hundred-twelve typically developing children were evaluated with tasks for inhibitory control and lexical skills, while ratings of temperament and language were collected from their caregivers. A Confirmatory Factor Analysis reveals that inhibitory control seems to be best described by a unitary dimension. A Structural Equation Model suggests that 78 % of the variance in vocabulary is explained by a model considering the language observed measures, the three temperamental dimensions, and inhibitory control and in which both temperamental attention and the latent dimension of inhibitory control are significantly related to vocabulary. In addition, inhibitory control does not mediate the relationship between temperament and language.
本研究旨在探究 2;3 岁至 3;0 岁儿童抑制控制的潜在结构。此外，还探讨了气质维度（社交定向、运动活动和注意力）、抑制控制与语言之间的关系。112 名典型发展儿童接受了抑制控制和词汇技能任务的评估，同时从他们的照顾者那里收集了气质和语言的评分。验证性因子分析表明，抑制控制似乎可以用一个单一的维度来最好地描述。结构方程模型表明，考虑到观察到的语言测量、三个气质维度以及抑制控制的词汇模型可以解释 78%的词汇方差，其中气质注意力和抑制控制的潜在维度与词汇显著相关。此外，抑制控制并不介导气质和语言之间的关系。
