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. Differences are also found in the evoked potential as a function of whether or not the sensorymodality of the stimulus was anticipated correctly. The major waveform alteration is in the amplitude of a positive-going component which reaches peak… Expand

Information Delivery and the Sensory Evoked Potential
The waveform of evoked responses recorded from human scalp is not determined solely by the physical eliciting stimulus, but also varies as a function of the effective information provided by theExpand
Evoked Potential Correlates of Auditory Signal Detection
A long-latency comnponent of the averaged evoked potential recorded from the human scalp varied in close relationship with subjects' perceptual reports in an auditory signal detection task. DetectedExpand
Knowledge of stimulus timing attenuates human evoked cortical potentials.
TLDR
The cognitive act of knowing when auditory stimuli will occur attenuates the amplitude and facilitates the poststimulus timing of cortical evoked potentials. Expand
Cerebral evoked potential correlates in forced-paced tasks.
TLDR
The evoked potential correlates of sensory overload in forced-paced auditory tasks are examined and it is found that the cerebral “decision” potential can reveal intermittency in the perceptual channel. Expand
Evoked Potential Correlates of Expected Stimulus Intensity
The electrophysiological responses to a flash of medium intensity have different wave shapes in trials in which the occurrence of bright stimuli or dim stimuli is expected. When a bright or dimExpand
Self-Stimulation Alters Human Sensory Brain Responses
Human electrocortical potentials evoked by self-administered auditory and visual stimuli manifest much smaller amplitude and faster poststimulus timing than do average brain responses evoked byExpand
Human auditory evoked potentials. II. Effects of attention.
TLDR
Evidence shows that human auditory attention is not mediated by a peripheral gating mechanism and that attention directed toward auditory stimuli causes a substantial increase in the N1 and P2 components of the auditory evoked potential without any change in preceding components. Expand

TLDR
Characteristics of the feedback-click waveforms were reliable within subjects, but were different across subjects and different from evoked potentials to informational or meaningful stimuli as generally reported in the literature. Expand
The Endogenous Evoked Potentials
This paper reviews some “endogenous” potentials that can be recorded from the human scalp in relation to the processing of sensory stimuli into behavioral responses. Twenty years ago, Sutton et al.Expand
Auditory stimulus processing at different stimulus intensities as reflected by auditory evoked potentials
TLDR
Evoked-potential equivalents of cognitive auditory stimulus processing could be shown to be loudness driven and to have highest amplitudes or shortest latencies at a stimulus loudness of 70 dB SL. Expand
