Individual Differences in Lexical Processing at 18 Months Predict Vocabulary Growth in Typically Developing and Late‐Talking Toddlers

Using online measures of familiar word recognition in the looking‐while‐listening procedure, this prospective longitudinal study revealed robust links between processing efficiency and vocabulary growth from 18 to 30 months in children classified as typically developing ( n = 46) and as “late talkers” ( n = 36) at 18 months. Those late talkers who were more efficient in word recognition at 18 months were also more likely to “bloom,” showing more...
