婴儿听到的大多数单词都是在流利的言语中出现的。因此，为了编制词汇表，婴儿需要从语音上下文中分割单词。这项研究首次调查了婴儿（此处为 10 个月大的婴儿）在初始接触和测试演示均为连续言语时是否能够识别单词。电生理学证据证明这种情况确实发生：相对于控制词，熟悉的目标词出现扩展的消极性（词识别效应）增加。事实证明，这种反应在个体层面上是恒定的：只有在测试中表现出这种消极情绪的婴儿在熟悉过程中第一次出现后的六次重复内才会表现出这样的反应。
Most words that infants hear occur within fluent speech. To compile a vocabulary, infants therefore need to segment words from speech contexts. This study is the first to investigate whether infants (here: 10-month-olds) can recognize words when both initial exposure and test presentation are in continuous speech. Electrophysiological evidence attests that this indeed occurs: An increased extended negativity (word recognition effect) appears for familiarized target words relative to control words. This response proved constant at the individual level: Only infants who showed this negativity at test had shown such a response, within six repetitions after first occurrence, during familiarization.
