Relationship between cognitive control and linguistic knowledge in 5 years old children

本研究探讨执行功能的发展是否影响语言知识的习得和运用。研究1考察了语言交际技能和执行功能（言语工作记忆和抑制功能）的个体差异。研究2进行了视觉世界范式实验，让5岁和6岁的儿童和成人理解颜色形容词短语。在研究3中，成人参与了视觉世界范式实验，其中视觉注意受视觉对比对象和句子理解过程的控制。综上所述，抑制功能主要促进语言加工的发展，对知识习得的贡献较小。

This study investigates whether development of executive function affects linguistic knowledge acquisition and utilization. Study 1 investigated individual differences of language-communication skills and executive functions(verbal working memory and inhibition function). Study 2 conducted a visual world paradigm experiment, where five-and six-years-old children and adults comprehended the color adjective phrases. In Study 3, adults participated a visual world paradigm experiment, where the visual attention was controlled by the visually contrastive objects and a sentence comprehension process. In summary, inhibition function primarily contributes to the development of language processing and its contribution to the knowledge acquisition is small.
