Attention and word learning in toddlers who are late talkers

J Child Lang. 2016 Sep;43(5):1020-37. doi: 10.1017/S0305000915000379.

Abstract

The purpose of this study was to examine attention allocation in toddlers who were late talkers and toddlers with typical language development while they were engaged in a word-learning task in order to determine if differences exist. Two-year-olds who were late talkers (11) and typically developing toddlers (11) were taught twelve novel pseudo-words for unfamiliar objects over ten training sessions. The toddlers' attention allocation during the word-learning sessions was measured as well as their comprehension of the newly learned words. Late talkers showed reduced attention allocation to objects during word-training sessions, and also comprehended fewer of the novel words than toddlers with typical language development. Attention allocation was found to be a stronger predictor of word learning as compared to cognition and auditory comprehension. Reduced attention allocation may contribute to the early lexical delay characteristic in late talkers.
