An ERP index of task relevance evaluation of visual stimuli.

TLDR
The results showed that the P2a was present to task-relevant stimuli but had the same scalp topography and estimated source-dipole locations in both overt and covert responding, indicative of an index of stimulus evaluation, rather than response production.

A Boost and Bounce theory of temporal attention

TL;DR: A general theory, as well as a working computational model, that explains many findings that are problematic for limited-capacity accounts, including a new experiment showing that the attentional blink can be postponed.

When Things Are Better or Worse than Expected: The Medial Frontal Cortex and the Allocation of Processing Resources

TL;DR: A passive reward prediction design containing neither instructed attention nor response is used to demonstrate that the ERP over medial frontal leads at the P2a/MFN latency is consistent with activity of midbrain DA neurons, positive to unpredicted rewards and negative when a predicted reward is withheld.

ERP--correlates of response selection in a response conflict paradigm.

TL;DR: It is proposed that the frontocentral negative ERP-component, the N2, is related to the process of response selection which influences subsequent processing stages reflected in the P3.

Error and feedback processing in children with ADHD and children with Autistic Spectrum Disorder: an EEG event-related potential study.

TL;DR: This study shows that measuring ERPs of error and feedback processing is a useful method for dissociating ADHD from ASD and elucidating medication effects in ADHD on component processes of performance monitoring.

Perception and communication

TL;DR: In this paper, the authors describe a transition between behaviourist learning theory and the modern information processing or cognitive approach to perception and communication skills, and provide a principal starting point for theoretical and experimental work on selective attention.

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.

Attention and brain function

TL;DR: This book delineates cerebral mechanisms of attention in humans as they presently appear in the light of data obtained by using various modern brain-research techniques and develops an integrative view of human information processing.

Scalp distributions of event-related potentials: An ambiguity associated with analysis of variance models

TL;DR: Using potential distributions generated by dipole sources in spherical volume conductor models, it is demonstrated that highly significant interactions involving electrode location can be obtained between scalp distributions with identical shapes generated by the same source.
