We report a developmental "mega-analysis" of the http://peekbank.stanford.edu dataset of eye-tracking during word recognition. Over years of effort by dozens of folks, we reconciled data from 30+ eye-tracking studies. This paper analyzes 24 datasets of kids ages 1-6 recognizing concrete nouns.

Our analysis shows continuous changes in the speed, accuracy, and variability of kids' word recognition. Consistent with "language as a skill" proposals, accuracy and log reaction time increase linearly in the log of age. Trial-wise variability decreases linearly in the log of age as well.

Word recognition is also coupled to total vocabulary size, consistent with proposals by Anne Fernald and Virginia Marchman. Kids who are faster language processors also show faster vocabulary growth.

In sum: word recognition is a skill that develops gradually across early childhood and this skill plays an important role in supporting early language learning!
