OBJECTIVE Target/standard discrimination difficulty was manipulated systematically to assess how this variable affects target and nontarget P300 scalp distributions for both auditory and visual stimuli. DESIGN AND METHODS A 3-stimulus paradigm (target, standard, nontarget) was employed in which subjects (n = 16) responded only to an infrequently occurring target stimulus. The perceptual discrimination difficulty between the target and more frequently occurring standard stimuli was varied as… Expand

P3a from Visual Stimuli: Typicality, Task, and Topography
TLDR
It is suggested that stimulus context as defined by the target/standard discrimination difficulty rather than stimulus novelty determines P3a generation. Expand
P3a, perceptual distinctiveness, and stimulus modality.
TLDR
The results support previous findings that target/standard stimulus context determines P3a generation for both auditory and visual stimulus modalities and suggest that the distinctiveness of the eliciting stimulus contributes to P 3a amplitude. Expand
Wavelet Analysis of P3a and P3b
TLDR
It is suggested that target/standard discrimination difficulty, rather than stimulus novelty, determines P3a generation for visual stimuli but that the underlying theta oscillations are differentially affected by stimulus novelty. Expand
Auditory and visual P300 topography from a 3 stimulus paradigm
TLDR
The findings suggest that both target and non-target stimuli in 3 stimulus oddball paradigm elicited the same type of P300 (P3b) for both stimulus modalities. Expand
P3a from auditory white noise stimuli
TLDR
White noise stimuli can be useful for clinical P3a applications, as it removes the variability of stimulus novelty, and indicates that white noise stimulus can produce reliable P 3a components. Expand
Stimulus context determines whether non-target stimuli are processed as task-relevant or distractor information
TLDR
The target/standard stimulus context influences the attentional set for stimulus processing such that it determines whether non-target stimuli are processed as task-relevant or distractor information. Expand

TLDR
The findings indicate that P3a from white noise is robust and should be useful for applied studies as it removes stimulus novelty variability. Expand
P3a from a passive visual stimulus task
TLDR
The P3a can be obtained with visual stimuli in the 3-stimulus paradigm under passive viewing conditions and theoretical implications and clinical applications are discussed. Expand
Increased visual task difficulty enhances attentional capture by both visual and auditory distractor stimuli
TLDR
This study investigated whether or not the increase of P3a can also be observed when the distractor stimuli are presented in a different modality from the standard and target stimuli, and found it could be reported when standard, target, and distractor stimulus were presented within one sensory modality. Expand
Distractor P3 is associated with attentional capture by stimulus deviance
TLDR
This is the first report showing that simple distractors can elicit large anteriorly distributed P3 in an easy task, and contributes to the clinical application of distractor P3 to assess the cognitive function of deviant processing. Expand

Stimulus context determines P3a and P3b.
TLDR
The findings suggest that target P300s are not influenced by the nontarget stimulus configuration, whereas the nontTarget P300 outcomes are determined directly by the stimulus context. Expand
P300 topography and modality effects from a single-stimulus paradigm.
TLDR
The findings suggest that the single-stimulus paradigm may be useful in experimental and applied contexts that require very simple ERP task conditions. Expand

TLDR
The findings suggest that the single-stimulus paradigm can provide reliable cognitive measures in clinical/applied testing for both passive and active response conditions. Expand

TLDR
The findings suggest that P300 amplitude and latency obtained from auditory discrimination paradigms reflect processing difficulty independently of stimulus target probability unless differences in task requirements affect stimulus encoding. Expand
Effects of rare non-target stimuli on brain electrophysiological activity and performance.
TLDR
Behavior (RT) and electrophysiological (event-related potential) data showed that stimuli that follow standard stimuli were processed differently compared to stimuli that followed deviant non-target stimuli. Expand
Intracerebral potentials to rare target and distractor auditory and visual stimuli. III. Frontal cortex.
TLDR
An early P3a-like activity that polarity inverts over short distances in the medial frontal lobe is demonstrated, and that it has a significantly shorter latency than similar potentials recorded in the temporal and parietal cortices. Expand
Intracerebral potentials to rare target and distractor auditory and visual stimuli. I. Superior temporal plane and parietal lobe.
TLDR
The early endogenous activity in auditory cortex may embody activity that is antecedent to the other patterns in multimodal association cortex, and may embody the cognitive closure that is also reflected in the scalp P3b or late positive component. Expand
Intracerebral potentials to rare target and distractor auditory and visual stimuli. II. Medial, lateral and posterior temporal lobe.
TLDR
Event-related potentials were recorded from 1221 sites in the medial, lateral and posterior aspects of the temporal lobe in 39 patients in order to localize seizure origin prior to surgical treatment. Expand

TLDR
The results suggest that P300 was produced by the same neural and cognitive mechanisms across tasks, and both P300 peak amplitude and latency demonstrated strong positive correlations between each pair of paradigms. Expand
The effect of stimulus deviation on P3 waves to easily recognized stimuli
TLDR
There are at least three different sets of circumstances under which P3 waves are triggered, each involving a different kind of processing, according to the a priori stimulus probability. Expand
