Journal ArticleDOI
Committee report: Guidelines for human startle eyeblink electromyographic studies.
Terry D. Blumenthal,Bruce N. Cuthbert,Diane L. Filion,Steven A. Hackley,Ottmar V. Lipp,Anton van Boxtel +5 more
TL;DR: Qualitative issues are raised and recommendations for optimal methods of startle blink electromyographic (EMG) response elicitation, recording, quantification, and reporting are presented.
Journal ArticleDOI
The effects of channel-selective attention on the mismatch negativity wave elicited by deviant tones.
TL;DR: Findings call into question the assertion that the auditory mismatch detection process and the associated MMN wave are wholly independent of attentional influence and provide evidence that the processing of stimuli in unattended channels can be attenuated or gated at an early sensory level under conditions of highly focused auditory selective attention.
Journal ArticleDOI
Electrophysiological evidence for temporal overlap among contingent mental processes.
Jeff Miller,Steven A. Hackley +1 more
TL;DR: Lateralized potentials in a choice reaction task with no-go trials indicate that movement preparation can begin once partial perceptual information about a stimulus becomes available, contrary to an assumption of fully discrete models of information processing.
Journal ArticleDOI
Cross-modal selective attention effects on retinal, myogenic, brainstem, and cerebral evoked potentials.
TL;DR: Results provide further evidence that the earliest levels of sensory transmission are unaffected by cross-modal selective attention, but that longer latency exogenous and endogenous potentials are enhanced to stimuli in the attended modality.
Journal ArticleDOI
Combined use of microreflexes and event-related brain potentials as measures of auditory selective attention.
TL;DR: Results indicate that evoked auditorv activity in the lower brainstem is obligatory and invariant with attention, whereas later activity mediated in the upper brainstem can be modulated by attention.
