* 成人和婴儿表现出类似的影响所产生的意想不到的单词形式。* 14个月大的婴儿表现出成人PMN效应的类似物。* 婴儿从225毫秒开始检测错误的元音，更大的变化提前75毫秒。* 成人语义N400效应与期望相关PMN效应是离散的。* 新的数据可视化方法集成了空间和时间信息。我们在一项事件相关电位（ERP）研究中测试了14个月大的婴儿和成人，在这项研究中，熟悉物体的图片会产生对即将到来的单词形式的预期。预期的单词形式标记的图片（词条件），而意外的单词形式不匹配的词中间元音高度的小偏差（发音错误的条件）或从第一个语音段的开始大偏差（pseudoword条件）。婴儿和成人都对这两种意想不到的单词形式表现出敏感性。成人表现出一系列离散效应：N1波的阳性，P2波的阴性（PMN效应）和N2波的阴性（N400效应）。婴儿表现出类似的模式，包括类似于成人P2效应的稳健效应。这些观察结果得到了一种新的可视化方法的支持，该方法显示了随着时间的推移头皮带内ERP的动态变化。结果表明，共享的处理机制在整个发展，即使是微妙的偏离预期的单词形式索引在两个年龄组的特征波的振幅在早期听觉诱发电位的减少。
* Adults and infants show similar effects generated by unexpected word forms. * 14-Month-olds show an analogue of the adult PMN effect. * Infants detect mispronounced vowels from 225 ms, and larger changes 75 ms earlier. * Adult semantic N400 effects are discrete from expectation-related PMN effects. * Novel data visualisation method integrates spatial and temporal information. We tested 14-month-olds and adults in an event-related potentials (ERPs) study in which pictures of familiar objects generated expectations about upcoming word forms. Expected word forms labelled the picture (word condition), while unexpected word forms mismatched by either a small deviation in word medial vowel height (mispronunciation condition) or a large deviation from the onset of the first speech segment (pseudoword condition). Both infants and adults showed sensitivity to both types of unexpected word form. Adults showed a chain of discrete effects: positivity over the N1 wave, negativity over the P2 wave (PMN effect) and negativity over the N2 wave (N400 effect). Infants showed a similar pattern, including a robust effect similar to the adult P2 effect. These observations were underpinned by a novel visualisation method which shows the dynamics of the ERP within bands of the scalp over time. The results demonstrate shared processing mechanisms across development, as even subtle deviations from expected word forms were indexed in both age groups by a reduction in the amplitude of characteristic waves in the early auditory evoked potential.
