Children's lexical processing speed at 18 to 25 months of age has been linked to concurrent and later language abilities. In the current study, we extend this finding to children aged 36 months. Children ( = 126) participated in a lexical processing task in which they viewed two static images on noun trials (e.g., an ear of corn and a hat), or two dynamic video clips on verb trials (e.g., a woman stretching and the same woman clapping), and heard an auditory prompt labeling one of them (e.g., "Where is she stretching?"). They also participated in standard assessments of language and school readiness. The results indicated that lexical processing speed (i.e., how long they required to look to the labeled image or scene) was associated with measures of concurrent receptive vocabulary, as well as receptive vocabulary and school readiness two years later, although the associations are weaker than for younger children.
18至25个月大儿童的词汇处理速度已被证明与同时期及后期的语言能力相关。在本研究中，我们将这一发现扩展至36个月大的儿童。126名儿童参与了一项词汇处理任务，在名词测试中他们观看两张静态图像（如一根玉米穗和一顶帽子），在动词测试中观看两段动态视频片段（如一名女性伸展身体和同一名女性鼓掌），并听到一个听觉提示，指示其中一个（如“她在哪里伸展身体？”）。他们还参与了语言和入学准备的标准评估。结果表明，词汇处理速度（即他们看向标记图像或场景所需的时间）与同时期接受性词汇量的测量指标相关，也与两年后的接受性词汇量和入学准备相关，尽管这些关联比年幼儿童的情况要弱。
