“…We also found that children with DLD showed overall reduced amplitude of the N200/PMN response in the early time window across conditions. This potential has been linked to both phonological processing (Connolly & Phillips, 1994; Lee, Harkrider, & Hedrick, 2012) and early semantic processing following the initial phonological analysis of the available (incomplete) information about the word and early lexical selection (van den Brink, Brown, & Hagoort, 2001). In our data, the PCA-derived amplitude of this component was positively related to the PCA-derived amplitudes of the N400 effect in both the IPO condition ( r = .432, p < .01) and the UR condition ( r = .341, p < .05), and also to the behavioral measure of lexical development ( r = –.363, p < .05) but not the measure of phonological development ( r = .126, p > .05).…”

Lexical processing deficits in children with developmental language disorder: An event-related potentials study

Lexical processing deficits in children with developmental language disorder (DLD) have been postulated to arise as sequelae of their grammatical deficits (either directly or via compensatory mechanisms) and vice versa. We examined event-related potential indices of lexical processing in children with DLD (n = 23) and their typically developing peers (n = 16) using a picture–word matching paradigm. We found that children with DLD showed markedly reduced N400 amplitudes in response both to auditorily presented words that had initial phonological overlap with the name of the pictured object and to words that were not semantically or phonologically related to the pictured object. Moreover, this reduction was related to behavioral indices of phonological and lexical but not grammatical development. We also found that children with DLD showed a depressed phonological mapping negativity component in the early time window, suggesting deficits in phonological processing or early lexical access. The results are partially consistent with the overactivation account of lexical processing deficits in DLD and point to the relative functional independence of lexical/phonological and grammatical deficits in DLD, supporting a multidimensional view of the disorder. The results also, although indirectly, support the neuroplasticity account of DLD, according to which language impairment affects brain development and shapes the specific patterns of brain responses to language stimuli.

“…The authors reported more prominent negative MMR and diminished positive MMR with increasing age. Lee et al. linked this result to the idea that enhanced and more mature sound discrimination mechanisms are reflected by the negative MMR and more difficult discrimination is reflected by the positive MMR. Other studies investigating kindergarten or school‐age children have reported an adult‐like frontal negative MMR (Čeponienė et al., ; Gomot et al., ; Molholm, Martinez, Ritter, Javitt, & Foxe, ; Shestakova et al., ), a frontal positive MMR (Maurer et al., ; Ruhnau, Wetzel, Widmann, & Schröger, ), or a negative MMR with parietal maximum (e.g., Maurer et al., ; Wetzel, Berti, Widmann, & Schröger, ).…”

“…Interestingly, different polarity of MMR has also been observed in older children. For example, Lee, Harkrider, and Hedrick () observed positive and negative MMRs in 4 to 6‐year‐old children when responding to three types of syllabic features in Mandarin. The authors reported more prominent negative MMR and diminished positive MMR with increasing age.…”

The present review focuses on the development of involuntary attention mechanisms in the context of the occurrence of unexpected events during childhood. We introduce a prevailing three-stage model of auditory involuntary attention describing the processes leading to, accompanying, and following the distraction of attention by prediction violations: (a) the automatic detection of prediction violations (associated with the event-related potential [ERP] component mismatch negativity [MMN]), (b) the involuntary orienting of attention processes towards the prediction violating sound (associated with the ERP component P3a), and (c) the reorienting back to task-relevant information (associated with the ERP components reorienting negativity [RON] or late discriminative negativity [LDN]). Within this framework we give an overview of studies investigating MMN, P3a, RON/LDN, and behavioral distraction effects in children. We discuss the development of the underlying involuntary attention mechanisms and highlight the relevance of and future perspectives for this important field of research.

“…We do not expect to find a PMN in this study, however. Although phonotactics can set up expectations for upcoming phonemes (Massaro & Cohen, 1983), violations of these expectations do not seem to elicit a PMN (Lee et al, 2012). Rather, previous studies that have found ERP effects of phonotactic well-formedness have generally found effects appearing much later than the PMN window: in the N400 or P600 windows, discussed below.…”

Violations of Lab-Learned Phonological Patterns Elicit a Late Positive Component

et al. 2023

The experimental study of artificial language learning has become a widely used means of investigating the predictions of theories of language learning and representation. Although much is now known about the generalizations that learners make from various kinds of data, relatively little is known about how those representations affect speech processing. This paper presents an event-related potential (ERP) study of brain responses to violations of lab-learned phonotactics. Novel words that violated a learned phonotactic constraint elicited a larger Late Positive Component (LPC) than novel words that satisfied it. Similar LPCs have been found for violations of natively acquired linguistic structure, as well as for violations of other types of abstract generalizations, such as musical structure. We argue that lab-learned phonotactic generalizations are represented abstractly and affect the evaluation of speech in a manner that is similar to natively acquired syntactic and phonological rules.
