婴儿何时以及如何发展出一个彼此相关的词汇语义系统？我们调查了词-词协会在早期词汇发展中使用适应的跨模态优先寻找任务，词对（而不是单一的目标词）被用来引导婴儿的注意力朝向目标图片。两个词（prime和target）被快速连续地呈现，之后婴儿被呈现一对图片（target和distracter）。启动目标词对是语义和联想相关或不相关的;目标是命名或未命名的。实验1表明，词汇语义启动效应的21个月的奥尔兹，但不为18个月奥尔兹：无关的启动词干扰语言目标识别21个月的奥尔兹。后续实验证实了不相关启动词的干扰效应，并确定了重复启动效应的存在，年轻的18个月的年龄。这些实验的结果表明，婴儿早在21个月大的时候就已经开始发展词汇之间的语义联想联系。
When and how do infants develop a semantic system of words that are related to each other? We investigated word-word associations in early lexical development using an adaptation of the inter-modal preferential looking task where word pairs (as opposed to single target words) were used to direct infants' attention towards a target picture. Two words (prime and target) were presented in quick succession after which infants were presented with a picture pair (target and distracter). Prime-target word pairs were either semantically and associatively related or unrelated; the targets were either named or unnamed. Experiment 1 demonstrated a lexical-semantic priming effect for 21-month olds but not for 18-month olds: unrelated prime words interfered with linguistic target identification for 21-month olds. Follow-up experiments confirmed the interfering effects of unrelated prime words and identified the existence of repetition priming effects as young as 18 months of age. The results of these experiments indicate that infants have begun to develop semantic-associative links between lexical items as early as 21 months of age.
