“…Along with differences in frequency band, differences were also evident in the moment-to-moment event related potentials (ERPs), with increased negativity evident around 350-550 ms over the scalp regions down the central midline. This time window is consistent with familiar N400-type incongruence between sound and meaning in infants around this age (for review, see Friedrich & Friederici, 2006), effects which have been observed when as little as a single vowel is incongruent with the typical label for a currently viewed picture (Duta, Styles, & Plunkett, 2012). Asano et al (2015) propose that in the case of 11-monthold infants, sound symbolism is processed perceptually, on the basis of crossmodal binding mechanisms.…”

“…The timing of this effect, and its direction, are congruent with reports of an ERP effect known as the phonological mapping negativity (PMN: Newman & Conolly, 2009;Steinhauer & Connolly, 2008), understood to index goodness of fit of a phonological form to expectations generated by contexts including written words (e.g., Connolly, Service, D'Arcy, Kujala, & Alho, 2001) and also picture stimuli (e.g., Duta et al, 2012). The effect has been shown to be discrete from well known N400 effects of semantic congruence, and can be observed around 230-310 ms (Desroches, Newman, & Joanisse, 2008).…”

“…The effect has been shown to be discrete from well known N400 effects of semantic congruence, and can be observed around 230-310 ms (Desroches, Newman, & Joanisse, 2008). The effect has also been observed to be graded, with larger deviations from expectation generating larger differences in the ERP (Duta et al, 2012). Consistent with a PMN, the effect reported here shows more negativity for stimuli presented in the incongruent condition, suggesting that the phonology of the written stimuli in the incongruent condition mismatch phonological expectations generated by the shape of the frame.…”

“…In our study, however, the two effects seem to occur in two separate latency windows, which suggests that the two effects might be reflecting different processes. An early congruency effect, separate from the N400, has also been reported for both 18-month-olds (Sheehan, Namy, & Mills, 2007) and 14-month-olds (Duta, Styles, & Plunkett, 2012;Mani, Mills, & Plunkett, 2012).…”

a b s t r a c tAround their first birthday infants begin to talk, yet they comprehend words long before. This study investigated the event-related potentials (ERP) responses of nine-month-olds on basic level pictureword pairings. After a familiarization phase of six picture-word pairings per semantic category, comprehension for novel exemplars was tested in a picture-word matching paradigm. ERPs timelocked to pictures elicited a modulation of the Negative Central (Nc) component, associated with visual attention and recognition. It was attenuated by category repetition as well as by the type-token ratio of picture context. ERPs time-locked to words in the training phase became more negative with repetition (N300-600), but there was no influence of picture type-token ratio, suggesting that infants have identified the concept of each picture before a word was presented. Results from the test phase provided clear support that infants integrated word meanings with (novel) picture context. Here, infants showed different ERP responses for words that did or did not align with the picture context: a phonological mismatch (N200) and a semantic mismatch (N400). Together, results were informative of visual categorization, word recognition and word-to-world-mappings, all three crucial processes for vocabulary construction.

“…Children need to be able to identify whether a word is familiar or novel quickly and accurately, even if it is similar to a word they already know. Children, as well as adults, have shown sensitivity to mispronunciations of familiar words, both behaviorally (e.g., Bailey & Plunkett, 2002; Ballem & Plunkett, 2005; Mani & Plunkett, 2007; Merriman & Schuster, 1991; Swingley & Aslin, 2000, 2002; White & Morgan, 2008) and neurophysiologically (e.g., Duta, Styles, & Plunkett, 2012; Friedrich & Friederici, 2005). …”

This study was designed to investigate the relationship between vocabulary size and the speed and accuracy of lexical processing in preschoolers between the ages of 30-46 months using an automatic eye tracking task based on the looking-while-listening paradigm (Fernald, Zangl, Portillo, & Marchman, 2008) and mispronunciation paradigm (White & Morgan, 2008). Children's eye gaze patterns were tracked while they looked at two pictures (one familiar object, one unfamiliar object) on a computer screen and simultaneously heard one of three kinds of auditory stimuli: correct pronunciations of the familiar object's name, one-feature mispronunciations of the familiar object's name, or a nonword. The results showed that children with larger expressive vocabularies, relative to children with smaller expressive vocabularies, were more likely to look to a familiar object upon hearing a correct pronunciation and to an unfamiliar object upon hearing a novel word. Results also showed that children with larger expressive vocabularies were more sensitive to mispronunciations; they were more likely to look toward the unfamiliar object rather than the familiar object upon hearing a one-feature mispronunciation of a familiar object-name. These results suggest that children with smaller vocabularies, relative to their larger-vocabulary age peers, are at a disadvantage for learning new words, as well as for processing familiar words.
