In an event-related potentials (ERP) study, twenty-month-old children (n = 37) were presented with pseudowords to map to novel object referents in five presentations. Quicker attenuation of the visual Negative central component (Nc) to novel objects predicted a larger difference in N400 amplitude between congruous and incongruous presentations of pseudowords at test. Furthermore, better initial recognition of familiar objects (Nc difference between familiar and novel objects) predicted the strength of the N400 incongruity effect to the verbal labels of these real objects. This study presents novel evidence for a link between efficient visual processing of objects and word learning ability.
在一项事件相关电位（ERP）研究中，20个月大的儿童（n = 37）在五次展示中被呈现伪词以映射到新的物体指称。视觉负中央成分（Nc）对新物体的更快衰减预测了测试时伪词一致和不一致展示之间N400振幅的更大差异。此外，对熟悉物体的更好初始识别（熟悉物体和新物体之间的Nc差异）预测了对这些真实物体的语言标签的N400不一致效应的强度。这项研究为物体的有效视觉处理与单词学习能力之间的联系提供了新的证据。
