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

On the Time Course of Visual Word Recognition: An Event-related Potential Investigation using Masked Repetition Priming
TL;DR: A strong modulation of the N400 and three earlier ERP components (P150, N250, and the P325) that the authors propose reflect sequential overlapping steps in the processing of printed words are shown.

TL;DR: There are robustly identifiable features of the ERP that enable labeling of ERPs as belonging to individuals with accuracy reliably above chance, and these features are stable over time, as indicated by continued accurate identification of individuals from ERPs after a lag of up to six months.

CEREBRE: A Novel Method for Very High Accuracy Event-Related Potential Biometric Identification
TL;DR: It is argued that the averaged event-related potential (ERP) may provide the potential for more accurate biometric identification, as its elicitation allows for some control over the cognitive state of the user to be obtained through the design of the challenge protocol.

Regression-based estimation of ERP waveforms: I. The rERP framework.
Nathaniel J. Smith,Marta Kutas +1 more
TL;DR: The regression-based rERP framework is introduced, which extends ERP averaging to handle arbitrary combinations of categorical and continuous covariates, partial confounding, nonlinear effects, and overlapping responses to distinct events, all within a single unified system.

Revisiting the incremental effects of context on word processing: Evidence from single‐word event‐related brain potentials
TL;DR: Modelling word-level variability in ERPs reveals mechanisms by which different sources of information simultaneously contribute to the unfolding neural dynamics of comprehension, as well as probing the continuous and incremental effects of semantic and syntactic context on multiple aspects of lexical processing during sentence comprehension.

Masked priming from orthographic neighbors: an ERP investigation.
TL;DR: Two experiments combined masked priming with event-related potential (ERP) recordings to examine effects of primes that are orthographic neighbors of target words, showing the standard inhibitory priming effect in lexical decision latencies that sharply contrasted with the facilitatory effects of nonword neighbor primes.

Won’t get fooled again: An event-related potential study of task and repetition effects on the semantic processing of items without semantics
TL;DR: This work collects ERPs from participants performing a modified Lexical Decision Task, in which the presence of orthographically illegal acronyms rendered meaningless illegal strings more difficult lures than normal, and found that under these conditions illegal strings elicited robust N400 repetition effects, quantitatively and qualitatively similar to those elicited by words, pseudowords, and acronymyms.

Parafoveal N400 effect during sentence reading.
TL;DR: N400 amplitudes to the critical triads were smaller when the right flanker was contextually congruent than incongruent, indicating that parafoveal information was extracted and quickly and incrementally integrated within the evolving sentence representation.

Testing an assumption of the E-Z Reader model of eye-movement control during reading: using event-related potentials to examine the familiarity check
TL;DR: An event-related potential (ERP) experiment designed to examine the hypothesized familiarity check at the electrophysiological level indicates ERP components modulated by word frequency at the time of the predicted familiarity check, consistent with the hypothesis that an early stage of lexical processing is linked to the "decisions" about when to move the eyes during reading.

TL;DR: In two experiments, event-related brain potentials were recorded to fragmented objects during an indirect memory test to isolate transfer of a specific perceptual process from overlap of physical features between experiences.
