Fernald, Anne; Marchman, Virginia A.; Weisleder, Adriana – Developmental Science, 2013
This research revealed both similarities and striking differences in early language proficiency among infants from a broad range of advantaged and disadvantaged families. English-learning infants ("n" = 48) were followed longitudinally from 18 to 24 months, using real-time measures of spoken language processing. The first goal was to…

Continuous Processing in Word Recognition at 24 Months.
Peer reviewed Peer reviewed
Swingley, Daniel; Pinto, John P.; Fernald, Anne – Cognition, 1999
Three experiments used a visual fixation technique to examine whether toddlers interpret speech continuously. Found that 24-month-olds had delayed responses when a competing distractor picture's label overlapped phonetically with the target at onset, but not when the pictures' labels rhymed, showing that children monitored speech stream…

Zangl, Renate; Klarman, Lindsay; Thal, Donna; Fernald, Anne; Bates, Elizabeth – Journal of Cognition and Development, 2005
Online comprehension of naturally spoken and perceptually degraded words was assessed in 95 children ages 12 to 31 months. The time course of word recognition was measured by monitoring eye movements as children looked at pictures while listening to familiar target words presented in unaltered, time-compressed, and low-pass-filtered forms. Success…

When Half a Word Is Enough: Infants Can Recognize Spoken Words Using Partial Phonetic Information.
Peer reviewed Peer reviewed
Fernald, Anne; Swingley, Daniel; Pinto, John P. – Child Development, 2001
Two experiments tracked infants' eye movements to examine use of word-initial information to understand fluent speech. Results indicated that 21- and 18-month-olds recognized partial words as quickly and reliably as whole words. Infants' productive vocabulary and reaction time were related to word recognition accuracy. Results show that…
