TLDR
This article examined the time course of influence of variables ranging from relatively perceptual (e.g., bigram frequency) to relatively semantic on ERP responses, analysed at the single-item level.Abstract:
Visual word recognition is a process that, both hierarchically and in parallel, draws on different types of information ranging from perceptual to orthographic to semantic. A central question concerns when and how these different types of information come online and interact after a word form is initially perceived. Numerous studies addressing aspects of this question have been conducted with a variety of techniques [e.g., behaviour, eye-tracking, event-related potentials (ERPs)], and divergent theoretical models, suggesting different overall speeds of word processing, have coalesced around clusters of mostly method-specific results. Here, we examine the time course of influence of variables ranging from relatively perceptual (e.g., bigram frequency) to relatively semantic (e.g., the number of lexical associates) on ERP responses, analysed at the single-item level. Our results, in combination with a critical review of the literature, suggest methodological, analytic and theoretical factors that may have led to inconsistency in results of past studies; we will argue that consideration of these factors may lead to a reconciliation between divergent views of the speed of word recognition.read more

An electrophysiological megastudy of spoken word recognition
TL;DR: The results support cascaded interactive models of spoken word recognition and their influence reflected changes in the timing of the ERP components.

Frequency and regularity effects in reading are task dependent: Evidence from ERPs
TL;DR: The use of event-related potentials to investigate whether and when effects of task modulate how visually presented words are processed demonstrates that task demands affect how meaning and sound are generated from written words.

Contextual constraints on lexico-semantic processing in aging: Evidence from single-word event-related brain potentials
TL;DR: Findings indicate that older adults are less likely (or able) to use accumulating top-down contextual constraints, and therefore rely more strongly on bottom-up lexical features to guide semantic access of individual words during sentence comprehension.

Altered patterns of directed connectivity within the reading network of dyslexic children and their relation to reading dysfluency
Gojko Žarić,Joao Correia,Gorka Fraga González,Jurgen Tijms,Maurtis W. van der Molen,Leo Blomert,Milene Bonte +6 more
TL;DR: In this article, the authors investigated whether dyslexia scales with the level of reading dysfluency by examining EEG recordings during visual word and false font processing in 9-year-old typically reading children (TR) and two groups of dyslexic children: severely dysfluent (SDD) and moderately dysfluent (MDD) dyslexics.

An event-related potential study of the relationship between N170 lateralization and phonological awareness in developing readers.
Elizabeth Sacchi,Sarah Laszlo +1 more
TL;DR: Test the phonological mapping hypothesis by collecting ERPs while children grades 5-6 viewed words, objects, and word/object ambiguous items and predicted left-lateralization of the N170 component elicited in response to words (but not item types that were not word-like).

Reading senseless sentences: brain potentials reflect semantic incongruity

TL;DR: In a sentence reading task, words that occurred out of context were associated with specific types of event-related brain potentials that elicited a late negative wave (N400).

Thirty years and counting: Finding meaning in the N400 component of the event related brain potential (ERP)
Marta Kutas,Kara D. Federmeier +1 more
TL;DR: The effectiveness of the N400 as a dependent variable for examining almost every aspect of language processing is emphasized and its expanding use to probe semantic memory is highlighted to determine how the neurocognitive system dynamically and flexibly uses bottom-up and top-down information to make sense of the world.

The MRC Psycholinguistic Database
TL;DR: A computerised database of psycholinguistic information is described, where semantic, syntactic, phonological and orthographic information about some or all of the 98,538 words in the database is accessible, by using a specially-written and very simple programming language.
