Augmenting mental chronometry: the P300 as a measure of stimulus evaluation time
TLDR
The data support the proposition that the latency of P300 corresponds to stimulus evaluation time and is independent of response selection.Abstract:
A technique for measuring the latency of the P300 component of event-related brain potentials on individual trials is described. Choice reaction times and the latency of the P300 were compared under speed-maximizing and under accuracy-mazimising instructions. The choice stimuli required different levels of semantic categorization. The data support the proposition that the latency of P300 corresponds to stimulus evaluation time and is independent of response selection.read more

TL;DR: The empirical and theoretical development of the P300 event-related brain potential is reviewed by considering factors that contribute to its amplitude, latency, and general characteristics.

Reading senseless sentences: brain potentials reflect semantic incongruity
Marta Kutas,Steven A. Hillyard +1 more
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).
Journal ArticleDOI
Is the P300 component a manifestation of context updating
TL;DR: The amplitude of the P300 component is controlled multiplicatively by the subjective probability and task relevance of eliciting events, whereas its latency depends on the duration of stimulus evaluation as mentioned in this paper.

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.

Evoked-Potential Correlates of Stimulus Uncertainty
TL;DR: The average evoked-potential waveforms to sound and light stimuli recorded from scalp in awake human subjects show differences as a function of the subject's degree of uncertainty with respect to the sensory modality of the stimulus to be presented.

TL;DR: A priori probability and sequential structure appear to be independent determinants of the P300 complex, which was assessed to determine the waveform of event-related potentials elicited by task-relevant stimuli.
